air.

The HRV is equipped with an aluminum core. The
device uses the stale air that is being exhausted to con­dition the fresh air as it is being brought in.

These instructions are intended as a general guide and do
not supersede local codes in any way. Consult authorities
who have jurisdiction before installation.

Location Selection

The HRV must be located in a heated space where it will
be possible to conveniently service the unit. Typically the
HRV would be located in the mechanical room or an area
close to the outside wall where the weather hoods will be
mounted. If a basement area is not convenient or does not
exist, a utility or laundry room may be used.

Attic installations are not normally recommended due to:

A) the complexity of work to install

B) freezing conditions in the attic

C) difficulty of access for service and cleaning

The HRV unit must be installed in a horizontal position as
shown in the illustration on the next page. The unit should
be suspended using the provided hanging straps. If nec­essary, the unit may be installed on a platform: however,
the cabinet should be isolated from the platform to prevent
vibration transmission. The unit must be level. Sufficient
clearance at the front of the access door is required for
servicing the air filters and core. A minimum of 25"
(635mm) clearance is recommended so the door can be
opened. Four PVC reinforced polyester hanging straps are
provided for hanging the HRV from the basement floor
joists.

Suspending the Unit

The hanging straps should be attached to the unit at the
top end corners (mounting screws are already located on
the HRV case). Securely fasten the other end of the straps
to the floor joists with wide head nails (not supplied), mak­ing sure the UNIT IS LEVEL. The straps are designed to
reduce the possibility of noise, resonance or harmonics;
therefore using the full length of the strap between the
HRV and the floor joists is recommended.

Weatherhood Location and Installation

Weatherhood kit includes two fixed-cover hoods with a 1/4”
(6mm) mesh screen.

Exhaust Weatherhood Requirements

• At least 6' (2 m) from the ventilation air intake*

• At least 18" (460 mm) above ground or above the
depth of expected snow accumulation*

Installation

Connecting Appliances to the HRV

The following appliances should not be connected to the
HRV:

• clothes dryer

• range top

• stovetop fan

• central vacuum system

NOTE: Connecting any of these to the HRV will

invalidate your warranty.

Clearances and Requirements

WARNING

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 air flows of
the ventilator, by using the balancing procedure
found in this manual.

CAUTION

It is always important to assess how the operation
of any HRV may interact with vented combustion
equipment (i.e. Gas Furnaces, Oil Furnaces,
Wood Stoves, etc.)

NEVER 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!

WARNING

Improper installation, adjustment, alteration,
service or maintenance can cause property
damage, personal injury or loss of life.
Installation and service must be performed by a
qualified installer or service agency.

WARNING

Electric shock hazard. Can cause
injury or death. Before attempting to
perform any service or maintenance,
turn the electrical power to unit OFF
at disconnect switch(es). Unit may
have multiple power supplies.

Lint, dust or grease will collect in the HRV
damaging the unit.

Air Duct Design and Installation

A well designed and installed ducting system will allow the
HRV to operate at its maximum efficiency.

Always try to keep duct runs as short and straight as pos­sible. See Installation Diagrams for various installation
options.

The inner and outer liners of the flexible insulated duct
must be clamped to the sleeve of the weather hoods (as
close to the outside as possible) and the appropriate port
on the HRV. It is very important that the fresh air intake line
be given special attention to make sure it is well sealed. A
good bead of high quality caulking (preferably

silicone sealant) will seal the inner flexible duct to both the
HRV port and the weather hood prior to clamping with a
large zip tie.

To minimize air flow restriction, the flexible insulated duct
that connects the two outside weather hoods to the HRV
should be stretched tightly and be as short as possible.

Twisting or folding the duct will severely restrict air flow.
See below for the recommended connection of flexible
insulated ducts to the the outside weather hoods and the
HRV.

Installing the Ducting Between
the HRV & Living Areas in the House

To maximize airflow in the duct system, all ducts should be
kept short and have as few bends or elbows as possible.
Forty-five degree elbows are preferred to 90° elbows. Use
“Y” tees instead of 90° elbows whenever possible.

All duct joints must be fastened with screws, rivets or duct
sealant and wrapped with mastic or a quality duct tape to
prevent leakage. Mastic is preferred but if duct tape is
used, we recommend aluminum foil duct tape.

Galvanized ducting from the HRV to the living areas in the
house is recommended whenever possible, although flexi­ble duct can be used in moderation if necessary.

To avoid possible noise transfer through the duct system, a
short length (approximately 12 inches or 300mm) of non­metallic flexible insulated duct should be connected
between the HRV and the supply/exhaust duct system.

The main supply and return lines to/from the HRV must be
5 inches (150mm) minimum. Branch lines to the individual
rooms may be as small as 4 inches (100mm), but 5 inch
(125mm) lines are preferred .

All ducts running through attics and unheated spaces must
be sealed and insulated to code.

Fresh Air Ducting

In applications that do not include an air handler, fresh
air should be supplied to all bedrooms and living areas,
excluding bathrooms, kitchen and utility areas. Grilles
should be located high on a wall or in ceiling locations.
Grilles

that diffuse the air comfortably such as the Round Diffuser

are recommended.

If the floor is the only option available, then special care
should be taken in locating grilles. Areas such as under
baseboard heaters will help to temper the air. Also optional
inline duct heaters are available for mounting in the supply
duct work to add heat if required.

Direct Connection to Air Handler Duct System

Should you wish to hard duct the fresh air from the HRV
directly into the cold air return of the air handler, remember
to check the air flow balance of the HRV with the air han­dler fan both "ON" and "OFF" to determine that it does not
imbalance the unit more than 10%.

Indirect Connection to Air Handler Duct System

If permitted by local codes, an indirect connection may
be made between the HRV fresh air duct and the air han­dler return plenum. The fresh air from the unit may be
directed at a grille installed in the cold air return duct of the
air handler. The fresh air outlet from the HRV should be no
closer than 4 inches (100mm) and no more than 12 inches
(300mm) from the grille.

WARNING

Include a short length of fabric, flex duct or
other non-metallic connector in the “Fresh Air to
Building” hard ducted line in order to keep the
HRV separately grounded (electrically) from the
air handler. This will avoid a possible shock
hazard to service people if a short to ground
develops in one of the devices.

Stale Air Exhaust System

The stale air exhaust system draws air from the points in
the house where the worst air quality problems occur.
Stale air ducts should be installed in the bathroom,
kitchen, and laundry room. Applications such as green­houses, atriums, swimming pools, saunas, etc. have
unique ventilation requirements which should be
addressed with an isolated ventilation system. Also, the air
handler return duct may be used to exhaust from. In this
method, the exhaust air is not ducted back to the HRV with
"dedicated lines" from bathrooms, kitchens, etc. Instead,
the exhaust air is drawn out of the cold air return of the air
handler. The air handler blower must be running when

the unit is operating for this system to be effective.

Balancing Dampers and Grilles

Balancing dampers and/or adjustable grilles should be
used to balance the flow rates into and out of various
rooms.

Grilles or diffusers should be positioned high on the wall or
in the ceiling. Kitchen exhaust grilles must never be con­nected to a range hood. They should be installed at least 4
feet (1.2m) horizontally away from the stove. A hinged
6”X10” (150 X 250mm) rectangular kitchen exhaust grille is
available as part number. This grille includes a removable
grease filter. Canadian building codes require that kitchen
grilles be equipped with washable filters.

Field-supplied balancing dampers should be installed
external to the unit to balance the amount of stale air
being exhausted with the amount of fresh air being
brought into the house. Refer to Air flow Balancing section.

The Round Diffuser is available in

4" (100mm)
5” (125mm)
6" (150mm)
8" (200mm)

Drain Connection (HRV Only)

During a defrost cycle, the HRV may produce some con­densation. This water should flow into a nearby drain, or
be taken away by a condensate pump.

The HRV cabinet has prepunched holes for the drain (see
below). Insert the drain spout through the hole in the drain
pan. Make certain the rubber washer is on the drain spout
before inserting.

Construct a P-Trap by looping the condensate hose and
taping in place.

Pour a cup of water into the P-Trap to create a water seal
which will prevent odours from being drawn up the hose
and into the fresh air supply to the HRV.
