GENERAL INFORMATION

Inspection

Upon receipt of the equipment, carefully check the

shipment against the bill of lading. Make sure all units

have been received. Inspect the carton or crating of each

unit, and inspect each unit for damage. Assure the carrier

makes proper notation of any shortages or damage on all

copies of the freight bill and completes a common carrier

inspection report. Concealed damage not discovered

during unloading must be reported to the carrier within

15 days of receipt of shipment. If not ﬁled within 15

days, the freight company can deny the claim without

recourse. Note: It is the responsibility of the purchaser

to ﬁle all necessary claims with the carrier. Notify the

ClimateMaster Trafﬁc Department of all damage within

ﬁfteen (15) days of shipment.

Storage

Equipment should be stored in its original packaging in

a clean, dry area. Store units in an upright position at all

times. Stack units a maximum of 2 units high.

Unit Protection

Cover units on the job site with either shipping packaging,

vinyl ﬁlm, or an equivalent protective covering. Cap

the open ends of pipes stored on the job site. In areas

where painting, plastering, and/or spraying has not been

completed, all due precautions must be taken to avoid

physical damage to the units and contamination by

foreign material. Physical damage and contamination

may prevent proper start-up and may result in costly

equipment clean-up.

Examine all pipes, ﬁttings, and valves before installing

any of the system components. Remove any dirt or trash

found in or on these components.

Pre-Installation

Installation, Operation, and Maintenance instructions

are provided with each unit.. The installation site chosen

should include adequate service clearance around the unit.

Before unit start-up, read all manuals and become familiar

with the unit and its operation

. Thoroughly check the

system before operation.

Prepare units for installation as follows:

1. Compare the electrical data on the unit nameplate

with ordering and shipping information to verify that

the correct unit has been shipped.

2. Keep the cabinet covered with the shipping

packaging until installation is complete and all

plastering, painting, etc. is ﬁnished.

DO NOT store or install units in corrosive environments

or in locations subject to temperature or humidity

extremes (e.g., attics, garages, rooftops, etc.) Corrosive

conditions and high temperature or humidity can

signiﬁcantly reduce performance, reliability, and service

life. Always move units in an upright position. Tilting

units on their sides may cause equipment damage.

▲WARNING!

3. Verify refrigerant tubing is free of kinks or dents and

that it does not touch other unit components.

4. Inspect all electrical connections. Connections must

be clean and tight at the terminals.

GLW Physical Data

▲CAUTION

Corrosive system water requires corrosion resistant

ﬁttings and hoses and possibly water treatment.

Optional pressure-rated hose assemblies designed

speciﬁcally for use with ClimateMaster units are available.

Similar hoses can be obtained from alternate suppliers.

Supply and return hoses are ﬁtted with swivel-joint ﬁttings

at one end to prevent kinking during installation.

Refer to Figure 1 for an illustration of a Supply/Return

Hose Kit. Male adapters secure hose assemblies to the

unit and risers. Install hose assemblies properly and

check them regularly to avoid system failure and reduced

service life.

Installation of Supply and Return Piping

Follow these piping guidelines.

1. Install a drain valve at the base of each supply and

return riser to facilitate system ﬂushing.

2. Install shut-off / balancing valves and unions at each

unit to permit unit removal for servicing.

3. Place strainers at the inlet of each system

circulating pump.

4. Select the proper hose length to allow slack between

connection points. Hoses may vary in length by +2%

to -4% under pressure.

5. Exceeding the minimum bend radius may cause the

hose to collapse which reduces water ﬂow rate. Install

an angle adapter to avoid sharp bends in the hose

when the radius falls below the required minimum

and causes a slight kink.

Insulation is not required on loop water piping except

where the piping runs through unheated areas or outside

the building or when the loop water temperature is below

the minimum expected dew point of the pipe ambient

temperature. Insulation is required if loop water

temperature drops below the dew point.

Pipe joint compound is not necessary when Teﬂon

threaded tape is pre-applied to hose assemblies or when

Figure 1: Supply/Return Hose Kit

PIPING INSTALLATION

▲CAUTION

Piping must comply with all applicable codes.

ﬂared-end connections are used. If pipe joint compound

is preferred, use compound only in small amounts on the

pipe threads of the ﬁtting adapters. Prevent sealant from

reaching the ﬂared surfaces of the joint.

Note: When anti-freeze is used in the loop, assure that

it is compatible with Teﬂon tape or pipe joint

compound employed.

Maximum allowable torque for brass ﬁttings is 30 ft-lbs

[41 N-m]. If a torque wrench is not available, tighten

ﬁnger-tight plus one quarter turn. Tighten steel ﬁttings

as necessary.

Do not bend or kink supply lines or hoses.

▲WARNING!

GLW Unit Location

These units are not designed for outdoor installation.

Locate the unit in an INDOOR area that allows

enough space for service personnel to perform typical

maintenance or repairs.

The installation of water source heat pump units and

all associated components, parts and accessories which

make up the installation shall be in accordance with

the regulations of ALL authorities having jurisdiction

and MUST conform to all applicable codes. It is the

responsibility of the Installing Contractor to determine

and comply with ALL applicable codes and regulations.

UNIT INSTALLATION

Locate the unit in an indoor area that allows easy removal

of access panels, and has enough space for service

personnel to perform maintenance or repair. Provide

sufﬁcient room to make water and electrical connections..

Any access panel screws that would be difﬁcult to remove

after the unit is installed should be removed prior to

setting the unit. These units are not approved for outdoor

installation and, therefore, must be installed inside the

structure being conditioned. Do not locate in areas where

ambient conditions are not maintained within 40-100°F

[4-38°C] and up to 75% relative humidity.

▲WARNING

Load and source piping must include a 20 mesh

[0.84mm] ﬁlter to control suspended particles

ﬂowing through the unit's plate heat exchangers.

ClimateMaster provides a 20 mesh (841 micron)

strainer in the commercial price list that is a

REQUIRED option for all GLW units regardless

of application type.

GLW Unit Load Plumbing

The applications are too varied to describe in this document.

However, some basic guidelines will be presented. Much of

the discussions on water loop applications would be valid for

the load plumbing discussion as well. All plumbing should

conform to local codes with the following considerations:

Wide temperature variation applications such as heating/

cooling coils:

- Employ piping materials that are rated for the maximum

temperature and pressure combination. This excludes

PVC for most heating applications.

- EMPLOY A 20 MESH (841 MICRON) [0.84MM]

PARTICULATE STRAINER IN BOTH LOAD AND

SOURCE PLUMBING TO PROTECT THE PLATE

HEAT EXCHANGERS.

LOAD PLUMBING INSTALLATION

- Insure that load water ﬂow in high temperature heating

applications is at least 3 gpm per ton [3.9 l/m per kW]

to improve performance and reduce nuisance high

pressure faults.

- DO NOT employ plastic to metal threaded joints

- Utilize a pressure tank and air separator vent system to

equalize pressure and remove air..

Swimming Pool Hot Tub Applications:

- Load coax should be isolated with secondary heat

exchanger constructed of anti-corrosion material in all

chlorine/bromine ﬂuid applications.

Genesis Large Water-to-Water (GLW) Series Page 7

COMMERCIAL WATER LOOP APPLICATIONS

Commercial systems typically include a number of units

plumbed to a common piping system. Any unit plumbing

maintenance work can introduce air into the piping system,

therefore air elimination equipment is a major portion

of the mechanical room plumbing. In piping systems

expected to utilize water temperatures below 50°F [10°C],

1/2" [13mm] closed cell insulation is required on all

piping surfaces to eliminate condensation. Metal to plastic

threaded joints should never be employed due to their

tendency to leak over time. Teﬂon tape thread sealant is

recommended to minimize internal fouling of the heat

exchanger. Do not overtighten connections and route

piping so as not to interfere with service or maintenance

access. Hose kits are available from ClimateMaster

in different conﬁgurations as shown in Figure 2 for

connection between the GLW Series and the piping system

For satisfactory operation of GLW360, it is essential to

control the suspended solid particles in water to below 20

mesh (841 micron) [0.84mm] size. It is mandatory that

minimum 20 mesh (841 micron) [0.84mm] strainer be used.

Installation with a high concentration of solid particles

over 20 mesh (841 micron) [0.84mm] size should consider

using ﬁlters with adequate and scheduled maintenance. The

hose kits include shut off valves, P/T plugs for performance

measurement, high pressure stainless steel braid hose,

"Y" type strainer 20 mesh (841 micron) [0.84mm])

with blowdown valve, and "J" type swivel connection.

Figure 2: Typical Water Loop Application.

Balancing valves to facilitate the balancing of the system,

and an external low pressure drop solenoid valve for use

in variable speed pumping systems, may also be included

in the hose kit. The piping system should be ﬂushed to

remove dirt, piping chips, and other foreign material prior

to operation. See page 17 for Piping System Cleaning and

Flushing Procedures. The ﬂow rate is usually set between

2.25 gpm and 3 gpm per ton [2.9 l/m and 4.5 l/m per kW]

of cooling capacity. ClimateMaster recommends 2.5 gpm

per ton [3.2 l/m per kW] for most applications of water loop

heat pumps. To insure proper maintenance and servicing, P/

T ports are imperative for temperature and ﬂow veriﬁcation,

as well as performance checks.

Cooling Tower/Boiler Systems typically utilize a

common loop maintained 60-90°F [16-32°C]. The use

of a closed circuit evaporative cooling tower with a

secondary heat exchanger between the tower and the

water loop is recommended. If an open type cooling tower

is used continuously, chemical treatment and ﬁltering will

be necessary.

Low Water Temperature Cutout Setting

CXM or DXM Control:

When an antifreeze is selected, the FP1 jumper (JW3)

should be clipped to select the low temperature (Antifreeze

15°F [-9.4°C]) setpoint to avoid nuisance faults. See Low

Water Temperature Cutout - FP1 on page 12.

Shut off valves should be included in case of servicing.

Boiler drains or other valves should be ʻteeʼdʼinto the line

to allow acid ﬂushing of just the heat exchanger. Pres-

sure temperature plugs should be used so that ﬂow and

temperature can be measured. Piping materials should be

limited to PVC SCH80 or copper.

Due to the pressure

and temperature extremes, PVC SCH40 is not recom-

mended.

Water quantity should be plentiful and of good

quality. Consult Table 2 for water quality guidelines.

For satisfactory operation of GLW360, it is essential to

control the suspended solid particles in water to below

20 mesh (841 micron) [0.84mm] size. It is mandatory

that minimum 20 mesh (841 micron) [0.84mm] strainer

be used. Installation with a high concentration of solid

particles over 841 micron [0.84mm] size should consider

using ﬁlters with adequate and scheduled maintenance.

The hose kits include shut off valves, P/T plugs for per-

formance measurement, and "Y" type strainer 20 mesh

(841 micron) [0.84mm] with blowdown valve.

In ground water situations where scaling could be heavy

or where biological growth such as iron bacteria will

be present, a closed loop system is recommended. Heat

exchangers may over time lose heat exchange capabilities

due to a build up of mineral deposits inside. These can be

cleaned only by a qualiﬁed service mechanic as acid and

special pumping equipment are required.

Genesis Large Water-to-Water (GLW) Series Page 9

In areas with extremely hard water, the owner should be

informed that the heat exchanger may require occasional

acid ﬂushing.

Expansion Tank and Pump

Use a closed, bladder-type expansion tank to minimize

mineral formation due to air exposure. The expansion

tank should be sized to handle at least one minute run

time of the pump to prevent premature pump failure us-

ing its drawdown capacity rating. Discharge water from

the unit is not contaminated in any manner and can be

disposed of in various ways depending on local building

codes; i.e. recharge well, storm sewer, drain ﬁeld, adjacent

stream or pond, etc. Most local codes forbid the use of

sanitary sewer for disposal. Consult your local building

and zoning department to assure compliance in your area.

Water Control Valve

Note the placement of the water control valve. Always

maintain water pressure in the heat exchanger by placing

water control valves at the outlet of the unit to prevent

mineral precipitation. Pilot operated or slow closing

valves are recommended to reduce water hammer. If

water hammer persists, a mini-expansion tank can be

mounted on the piping to help absorb the excess hammer

shock. Insure that the total ʻVAʼdraw of the valve can be

supplied by the unit transformer. For instance, some slow

closing valves can draw up to 35VA. This can overload

smaller transformers depending on the other controls

employed. A typical pilot operated solenoid valve draws

approximately 15VA. Note the special wiring diagram of

the AVM valve.

Flow Regulation

Flow regulation can be accomplished by two methods.

First, most water control valves have a built in ﬂow

adjustment. By measuring the pressure drop through the

unit heat exchanger, ﬂow rate can be determined and

compared to Table 6. Since the pressure is constantly

varying, two pressure gauges might be needed. Simply

adjust the water control valve until the desired ﬂow of

1.5 to 2 gpm per ton [2.0 to 2.6 l/m per kW] is achieved.

Secondly, a ﬂow control device may be installed. The

devices are typically an oriﬁce of plastic material that

is designed to allow a speciﬁed ﬂow rate. These are

mounted on the outlet of the water control valve. On

occasion, these valves can produce a velocity noise that

can be reduced by applying some back pressure. This is

accomplished by slightly closing the leaving isolation

valve of the well water setup.

Freeze Protection Thermistor

For all open loop systems the 35°F [1.7

°C]

FP1 setting

(factory setting-water) should be used to avoid freeze

damage to the unit. See "Low Water Temperature Cutout

- FP1" (Page 12).

▲WARNING

Load and source piping must include a 20 mesh

[0.84mm] ﬁlter to control suspended particles

ﬂowing through the unit's plate heat exchangers.

ClimateMaster provides a 20 mesh (841 micron)

strainer in the commercial price list that is a

REQUIRED option for all GLW units regardless

of application type.

▲CAUTION

Page 10 Genesis Large Water-to-Water (GLW) Series

GROUND LOOP APPLICATIONS

Pre-Installation

Prior to installation, locate and mark all existing

underground utilities, piping, etc. Install loops for new

construction before sidewalks, patios, driveways, and other

construction has begun. During construction, accurately

mark all ground loop piping on the plot plan as an aid in

avoiding potential future damage to the installation.

Piping Installation

All earth loop piping materials should be limited to only

polyethylene fusion for inground sections of the loop.

Galvanized or steel ﬁtting should not be used at any time

due to their tendency to corrode. All plastic to metal

threaded ﬁttings should be avoided due to their potential

to leak in earth coupled applications and a ﬂanged ﬁtting

substituted. P/T plugs should be used so that ﬂow can

be measured using the pressure drop of the unit heat

exchanger in lieu of other ﬂow measurement means. Earth

loop temperatures can range between 25 to 110°F [-4

to 43°C], and 2.25 to 3 gpm of ﬂow per ton [2.9 l/m to

3.9 l/m per kW] of cooling capacity is recommended in

these applications. Upon completion of the ground loop

piping, pressure test the loop to assure a leak free system.

Horizontal Systems: Test individual loops as installed.

Test entire system when all loops are assembled. Vertical

U-Bends and Pond Loop Systems: Test Vertical U-bends

and pond loop assemblies prior to installation with a test

pressure of at least 100 psi [689 kPa].

Flushing the Earth Loop

Upon completion of system installation and testing, ﬂush

the system to remove all foreign objects and purge to

remove all air.

▲CAUTION

The following instructions represent industry accepted

installation practices for Closed Loop Earth Coupled Heat

Pump Systems. They are provided to assist the contractor

in installing trouble free ground loops. These instructions

are recommended only. State and Local Codes MUST

be followed and installation MUST conform to ALL

applicable Codes. It is the responsibility of the Installing

contractor to determine and comply with ALL applicable

Codes and Regulations.

Antifreeze

In areas where minimum entering loop temperatures drop

below 40°F [5°C] or where piping will be routed through

areas subject to freezing, anti-freeze is needed. Alcohols

and glycols are commonly used as antifreezes, however

your local sales manager should be consulted for the an-

tifreeze best suited to your area. Freeze protection should

be maintained to 15°F [9°C] below the lowest expected

entering loop temperature. For example, if 30°F [-1°C]

is the minimum expected entering loop temperature, the

leaving loop temperature would be 25 to 22°F [-4 to -6°C]

and freeze protection should be at 15°F [-10°C] e.g. 30°F

- 15°F = 15°F [-1°C - 9°C = -10°C]. All alcohols should

be premixed and pumped from a reservoir outside of the

building when possible or introduced under water level to

prevent fuming. Initially calculate the total volume of ﬂuid

in the piping system. Then use the percentage by volume

shown in Table 3 for the amount of antifreeze. Antifreeze

concentration should be checked from a well mixed

sample using a hydrometer to measure speciﬁc gravity.

Freeze Protection Setting

CXM or DXM Control:

When an antifreeze is selected, the FP1 jumper [JW3]

should be clipped to select the low temperature (Anti-

freeze 15°F [-9.4

°C])

setpoint to avoid nuisance faults.

▲WARNING

Load and source piping must include a 20 mesh

[0.84mm] ﬁlter to control suspended particles

ﬂowing through the unit's plate heat exchangers.

ClimateMaster provides a 20 mesh (841 micron)

strainer in the commercial price list that is a
