General Information

CAUTION! 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

signi¿cantly reduce performance, reliability, and service life.

Always move and store units in an upright position. Tilting

units on their sides may cause equipment damage.

ѥCAUTION! ѥ

Pre Installation

CAUTION! CUT HAZARD - Failure to follow this caution

may result in personal injury. Sheet metal parts may have

sharp edges or burrs. Use care and wear appropriate

protective clothing, safety glasses and gloves when

handling parts and servicing heat pumps.

Inspection

Upon receipt of the equipment, carefully check the shipment

against the bill of lading. Make sure all units have been

received. Inspect the packaging of each unit, and inspect each

unit for damage. Insure that 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 ¿led

within 15 days, the freight company can deny the claim without

recourse. Note: It is the responsibility of the purchaser to ¿le

all necessary claims with the carrier. Notify your equipment

supplier of all damage within ¿fteen (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 3 units high.

Unit Protection

Cover units on the job site with either the original packaging

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, ¿ttings, and valves before installing any of

the system components. Remove any dirt or debris found in

or on these components.

Pre-Installation

Installation, Operation, and Maintenance instructions are

provided with each unit. Horizontal equipment is designed for

installation above false ceiling or in a ceiling plenum. Other

unit con¿gurations are typically installed in a mechanical

room. 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 original packaging until

installation is complete and all plastering, painting, etc. is

¿nished.

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.

5. Remove any blower support packaging (water-to-air

units only).

6. Loosen compressor bolts on units equipped with

compressor grommet vibration isolation until the

compressor rides freely on the grommets.

7. Locate and verify any hot water generator (HWG), hanger,

or other accessory kit located in the compressor section

or blower section.

Horizontal Installation

Mounting Horizontal Units

Horizontal units have hanger kits pre-installed from the

factory as shown in Figure 1. Figure 3 shows a typical

horizontal unit installation.

Horizontal heat pumps are typically suspended above a

ceiling or within a sofﬁt using ﬁeld supplied, threaded rods

sized to support the weight of the unit.

Use four (4) ﬁeld supplied threaded rods and factory

provided vibration isolators to suspend the unit. Hang the

unit clear of the ﬂoor slab above and support the unit by the

mounting bracket assemblies only. DO NOT attach the unit

ﬂush with the ﬂoor slab above.

Pitch the unit toward the drain as shown in Figure 2 to

improve the condensate drainage. On small units (less than

8.8kW) ensure that unit pitch does not cause condensate

leaks inside the cabinet.

Drain

Connection

1/4” (6.4mm) pitch

toward drain for drainag

Figure 1: Hanger Bracket

Figure 2: Horizontal Unit Pitch

Horizontal Unit Location

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

without removing unit from the ceiling. Horizontal units

are typically installed above a false ceiling or in a ceiling

plenum. Never install units in areas subject to freezing or

where humidity levels could cause cabinet condensation

(such as unconditioned spaces subject to 100% outside air).

Consideration should be given to access for easy removal of

the ﬁlter and access panels. Provide suﬃcient room to make

water, electrical, and duct connection(s).

If the unit is located in a conﬁned space, such as a closet,

provisions must be made for return air to freely enter the

space by means of a louvered door, etc. Any access panel

screws that would be diﬃcult to remove after the unit is

installed should be removed prior to setting the unit. Refer to

Figure 3 for an illustration of a typical installation. Refer to unit

speciﬁcations catalog for dimensional data.

Conform to the following guidelines when selecting

unit location:

Provide a hinged access door in concealed-spline or

plaster ceilings. Provide removable ceiling tiles in T-bar

or lay-in ceilings. Refer to horizontal unit dimensions for

speciﬁc series and model in unit speciﬁcations catalog.

Size the access opening to accommodate the service

technician during the removal or replacement of the

compressor and the removal or installation of the unit

itself.

Provide access to hanger brackets, water valves and

ﬁttings. Provide screwdriver clearance to access panels,

discharge collars and all electrical connections.

3. DO NOT obstruct the space beneath the unit with piping,

electrical cables and other items that prohibit future

removal of components or the unit itself.

4. Use a manual portable jack/lift to lift and support the

weight of the unit during installation and servicing.

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.

Figure 5: Right Return Side to Back

Figure 4: Left Return Side to Back

Overview -

Horizontal units can be ﬁeld converted between

side (straight) and back (end) discharge using the instructions

below.

Note: It is not possible to ﬁeld convert return air between left or

right return models due to the necessity of refrigeration copper

piping changes.

Preparation - It is best to ﬁeld convert the unit on the ground

before hanging. If the unit is already hung it should be taken

down for the ﬁeld conversion.

Side to Back Discharge Conversion

Place unit in well lit area. Remove the screws as shown in

Figure 4 to free top panel and discharge panel.

2. Lift out the access panel and set aside. Lift and rotate

the discharge panel to the other position as shown, being

careful with the blower wiring.

Check blower wire routing and connections for tension or

contact with sheet metal edges. Reroute if necessary.

4. Check refrigerant tubing for contact with

other components.

5. Reinstall top panel and screws noting that the location for

some screws will have changed.

6. Manually spin the fan wheel to ensure that the wheel is

not rubbing or obstructed.

7. Replace access panels.

Back to Side Discharge Conversion - If the discharge is

changed from back to side, use above instruction noting that

illustrations will be reversed.

Left vs. Right Return - It is not possible to ﬁeld convert return

air between left or right return models due to the necessity of

refrigeration copper piping changes. However, the conversion

process of side to back or back to side discharge for either

right or left return conﬁguration is the same. In some cases,

it may be possible to rotate the entire unit 180 degrees if the

return air connection needs to be on the opposite side. Note

that rotating the unit will move the piping to the other end of the

unit.

Figure 6: Horizontal Condensate Connection

Horizontal Installation

Condensate Piping – Horizontal Units

Pitch the unit toward the drain as shown in Figure 2 to

improve the condensate drainage. On small units (less

than 2.5 tons/8.8 kW), insure that unit pitch does not cause

condensate leaks inside the cabinet.

Install condensate trap at each unit with the top of the trap

positioned below the unit condensate drain connection as

shown in Figure 6. Design the depth of the trap (water-seal)

based upon the amount of ESP capability of the blower

(where 2 inches [51mm] of ESP capability requires 2 inches

[51mm] of trap depth). As a general rule, 1-1/2 inch [38mm]

trap depth is the minimum.

Each unit must be installed with its own individual trap and

connection to the condensate line (main) or riser. Provide

a means to ﬂush or blow out the condensate line. DO NOT

install units with a common trap and/or vent.

Always vent the condensate line when dirt or air can collect

in the line or a long horizontal drain line is required. Also vent

when large units are working against higher external static

pressure than other units connected to the same condensate

main since this may cause poor drainage for all units on the

line. WHEN A VENT IS INSTALLED IN THE DRAIN LINE, IT

MUST BE LOCATED AFTER THE TRAP IN THE DIRECTION

OF THE CONDENSATE FLOW.

 CAUTION! 

Duct System Installation

The duct system should be sized to handle the design

airﬂow quietly. Refer to Figure 3 for horizontal duct system

details or ﬁgure 8 for vertical duct system details. A ﬂexible

connector is recommended for both discharge and return

air duct connections on metal duct systems to eliminate

the transfer of vibration to the duct system. To maximize

sound attenuation of the unit blower, the supply and return

plenums should include internal ﬁberglass duct liner or be

constructed from ductboard for the ﬁrst few feet. Application

of the unit to uninsulated ductwork in an unconditioned

space is not recommended, as the unit’s performance will be

adversely aﬀected.

At least one 90° elbow should be included in the supply

duct to reduce air noise. If air noise or excessive air ﬂow is

a problem, the blower speed can be changed. For airﬂow

charts, consult speciﬁcations catalog for the series and

model of the speciﬁc unit.

If the unit is connected to existing ductwork, a previous

check should have been made to insure that the ductwork

has the capacity to handle the airﬂow required for the unit.

If ducting is too small, as in the replacement of a heating

only system, larger ductwork should be installed. All existing

ductwork should be checked for leaks and repaired as

necessary.

DUCT SYSTEM INSTALLATION

CAUTION! Ensure condensate line is pitched toward drain

1/8 inch per ft [11mm per m] of run.
