Sizing (Example) for maximum airflow normally required.

HRVs are typically sized to ventilate the whole house at a minimum of 0.35 air changes per
hour. To calculate, simply take the square footage of the house (including basement) and multi­ply by the height of the ceiling to get cubic volume. Then, divide by 60 and multiply by 0.35.
Example: SQFT of House 1100

Basement 1100

Total SQFT 2200

Compact top port design HRV with easy-mount wall bracket.
Brings a continuous supply of fresh air into a home while
exhausting an equal amount of contaminated air. HRVs use
what is called a “sensible” heat recovery core. This special
core transfers heat from the exhaust air stream to the
incoming air stream. Fresh incoming air is tempered by the
heat that is transferred from the outgoing air to save on
energy costs. The PHRV96 is equipped with automatic
defrost mechanisms so even if you live in the coldest cli­mates you can use your HRV all year long.

SPECIFICATIONS

CASE 24 gauge galvanized steel. Baked powder coated paint,

grey. Cabinet fully insulated with 1" (25 mm) aluminum foil­face high density polystyrene foam to prevent condensation
and meet the requirements of the UL 94HF.

MOTORS Two (2) German-manufactured, factory-balanced
ebm™ motors with backward curved blades. Motors come
with permanently lubricated sealed ball bearings to
guarantee long life and maintenance-free operation. Seven
(7) year warranty. Steep fan curves requires no balancing of
airflows.

CORE Aluminum heat recovery core configured for efficient
cross-flow ventilation. Core is 8.5˝ x 8.5˝ (216 x 216 mm)
with a 8˝ (205 mm) depth. Cores are manufactured by
Fantech to withstand extreme temperature variations.

FILTERS Two (2) Washable Electrostatic Panel Type Air Filters,

8.5˝ (216mm) x 8˝ (203mm) x 0.125˝ (3mm).

CONTROLS Unit is designed to accommodate the whole
series of Fantech HRV controls.

DEFROST

an outdoor air temperature of 23°F (-5°C) and lower. During
the defrost sequence, the supply blower shuts down & the
exhaust blower switches into high speed to maximize the
effectiveness of the defrost strategy. The unit then returns
to normal operation for 25 minutes, and continues cycle.

SERVICEABILITY Core, filters, motors and drain pan can be
easily accessed through latched door. Core conveniently
slides out on our new easy glide core guides. 10˝ (250mm)
of clearance is recommended for removal of core.

INSTALLATION

PRACTICAL TIPS

• Install the unit close to the outside
wall on which the supply and
exhaust hoods will be mounted.

• Have a nearby power supply 120
Volts, 60Hz. (power cord is 3
feet long)

• Mount the unit as level as
possible in order to allow proper
condensate drainage.

LOCATION

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

ould be located in the mechanical room or an area close to the outside wall where the weatherhoods will be mounted.

w
If a basement area is not convenient or does not exist, a utility room or laundry or closet may be used.
Attic installations are not normally recommended due to:

Connecting the following appliances to the HRV

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

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

- the complexity of work to install

- freezing conditions in the attic

- difficulty of access for service and cleaning

clothes dryer

-

- range top

- stovetop fan

- central vacuum system

is not recommended,

including:

• Have access to a water drain for
the condensate of the unit during
defrost.

• Have a certain amount of heat
around the unit (attic installation
is not recommended).

• Installations close to the living
space, such as closets, should be
design and to minimize noise or
vibration transfers.

• Have access for future
maintenance. (10” is
recommended for removal of core)

INSTALLING DRAIN LINE - Drainline not included in kit

Through normal operation and during its 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 the freezing point. A “P” trap should be made in the drain line. This
will prevent odors from being drawn back up into the unit.

1 Install the drain nipple.

2 Install the drain hose,
