information Practical tip

PLEASE READ THIS MANUAL BEFORE INSTALLING UNIT

Before installation, careful consideration must be given to how this system will operate if connected to any other

piece of mechanical equipment, i.e. a forced air furnace or air handler, operating at a higher static. After installation,

the compatibility of the two pieces of equipment must be confirmed by measuring the airflow’s of the Heat / Energy

Recovery Ventilators. It is always important to assess how the operation of any HRV/ERV may interact with vented

combustion equipment (i.e. Gas Furnaces, Oil Furnaces, Wood Stoves, etc.).

Install a ventilator in a situation where its normal operation, lack of operation or partial failure may result in the

backdrafting or improper functioning of vented combustion equipment!!!

Products are designed and manufactured to provide reliable performance, but they are not guaranteed to be 100%

free of defects. Even reliable products will experience occasional failures, and this possibility should be recognized

by the user. If these products are used in a life support ventilation system where failure could result in loss or injury,

the user should provide adequate back-up ventilation, supplementary natural ventilation or failure alarm system, or

acknowledge willingness to accept the risk of such loss or injury.

Your ventilation system should be installed in accordance with the local building code that is in effect, in absence

of such requirements, it is recommenced to check with local authorities having jurisdiction in your area prior to

installing this product.

Here are the conditions that permit moisture reduction enclosure.

• Ventilation is a year round solution for providing better indoor air quality. Ventilation also provides moisture removing capabilities but may not be

sufficient to control excess moisture year round.

• The pool and its environment must be operated according to the ASHRAE Application handbook guidelines. Failure to do so may lead to excessive

moisture conditions. Consult with our technical support department for further assistance on sizing and guidelines. Unit should be set up and com-

missioned by qualified individuals.

Installation

Location

The HRV must be located in a conditioned space where it will be possible to conveniently service the unit. Typically the HRV would be located in the

mechanical room, above a drop ceiling or an area close to the outside wall where the weatherhoods will be mounted. Attic installations are not recom-

mended due to extreme temperatures, and difficulty in performing, required service & maintenance. Care must be taken to locate the recirculation port in

an area that will not cause any unwanted contaminant to be drawn into the living space during recirculation and defrost.

Flexible duct connectors should be installed between the HRV and the galvanized ductwork.

Connecting appliances to the HRV It is not recommended, including:

• clothes dryer

• kitchen exhaust hoods

• combustion venting

• central vacuum system

These appliance may cause lint, dust or grease to collect in the HRV , damaging the unit.

Connecting any of these type of appliances to the HRV will invalidate your warranty

Installing Drain Line

Through normal operation and including defrost mode, the HRV may produce some condensation. This water should flow into a nearby drain, or be taken

away by a condensate pump. The HRV and all condensate lines must be installed in a space where the temperature is maintained above freezing point. A

“P” trap should be made in the drain line. This will prevent odors from being drawn back up into the unit.

Installing ducts going to / from outside

INSTALLING THE DUCTING TO THE WEATHERHOODS

OUTSIDE WEATHERHOODS – The weatherhoods must have built-in "bird" screens with 6.35 mm (1/4 inch) minimum mesh to prevent birds and rodents

from entering into the ductwork. Do not use smaller mesh as it will be very susceptible to plugging up. The preferred location of the weatherhoods is:

• No less than 3 m (10 ft.) apart from each other.

• At least 457.2 mm (18 inches) snow line or ground level.

• Supply hood must be kept away from sources of contaminant, such as automobile exhaust fumes, gas meters, garbage cans, containers,

cooling towers, tar roofs, etc.

• Avoid prevailing winds, whenever reasonably possible.

The outside perimeter of the weatherhood must be sealed to prevent leakage into the building.

DUCTING FROM THE WEATHERHOODS–TO AND FROM THE HRV – Galvanized sheet metal ducting with sufficient cross section with an integral single piece

of insulated wrap with vapor barrier should be used to connect the HRV to the weatherhoods. The R-value of the insulation should be adequate for

condensation control. Insulated flex duct may be used in moderation, if sized and installed properly. (Consult local codes)

All ducts should be sealed using a good bead of high quality caulking (preferably acoustical sealant) and a high quality aluminum foil tape, or other

approved duct sealant.

AThe duct’s airflow velocity

is generally measured

with a magnehelic gauge

and a pitot tube.

• To avoid airflow turbulence

and incorrect readings, the

airflow velocity should be

measured on steel ducting

a minimum of 3 duct

cross-section from the unit

or elbow and before any

transition.

• The balancing procedure consists of measuring the exhaust air leaving the system and the supply air entering the system and ensuring that these

two are equal. A deviation of 10% or less is acceptable.

AIR FLOW BALANCING

Pitot tube and gauge

A professional air balancer should be contacted to commission the system properly. A skilled HVAC Tech may complete the bal-

ance of air providing they possess the proper equipment. Call Fantech Technical support for assistance.

Exhaust Air ducting

The stale air exhaust system is used to draw air from the points in the building where the worst air quality problems occur. ( See installation

examples in the manual.)

Installing ducts to / from inside

Direct Connection to Furnace/ Air handler return duct

• Should you wish to hard duct the supply air directly into the cold air return of the HVAC systems, remember to check the airflow balance of the HRV

with the HVAC systems fan both “on”and “off” to determine that it does not imbalance the HRV more than 10%. Make sure you respect the minimum

distance from the supply air in of the HRV and the HVAC systems.

• It may be necessary to install a separate fresh air supply ductwork system if the heating is other than forced air.

When installing an HRV, the designer and installer should be aware of local codes that may require smoke detectors and/or firestats in the HVAC

or HRV ductwork.

Because an HRV is designed to bring fresh air into the building, structures may require supply voltage interrupt when smoke or flame sensors are

triggered, or when a central fire alarm system is activated.

To maximize airflow in the ductwork system, all ducts should be kept short and have as few bends or elbows as possible. Forty-five degree are

preferred to 90Þ elbows. Use “Y” tees instead of 90Þ elbows whenever possible.

All duct joints must be fastened with screws or duct sealant and wrapped with a quality duct tape to prevent leakage. Aluminum foil duct tape is

recommended.

SUPPLY AIR DUCTING

In buildings without a forced air HVAC systems, fresh air should be supplied to all habitable areas. It should be supplied from high wall or ceiling

locations. The grilles that are to be used should be designed to properly and comfortably sweep cold surfaces.

Optional inline duct heaters may be used to add heat if required. Typically the reheat is best done using a coil off the same boiler that heats the pool water.

1. Loosely fasten both

brackets “B” to cabinet

using screws in the pilot

holes (Fig. 1). Don’t drive

the screw all the way;

leave about ¼” of thread

for the step 4.

2. Using the same screw

already on the unit,

assemble bracket “A” on

the cabinet (Fig. 2).

3. Install BPM by tilting it

(Fig. 3) so that the hole

on the mounting bracket

“A” lines up with the

pilot hole on top of the

BPM. Secure it with the

fastener and release

the BPM. The tilting

will enable the hole to

line up properly and will

compress the gasket

once released.

4. Assemble the remaining fasteners to secure the BPM

(Fig. 4). Continue to tighten the fasteners holding the

bracket “B” to cabinet in order to compress the gasket

between the BPM and the cabinet (Fig. 5).
