1. TYPICAL INSTALLATIONS

Installations may vary according to the model number and the position in which the unit is installed. Use the following illustrations as
guidelines to help you decide on how your unit will be installed.

All the units should be hung from the joists, and installed either vertically or horizontally.
NOTE: For more details, see Point 5.2 in Section 5 INSTALL THE UNIT.
In every case, bathroom fans and a range hood should be used to exhaust stale air. Also, for homes with more than one level, we

recommend one exhaust register at the highest level.
There are 3 installation methods: Stand Alone, Central Draw Point and Return-to-Return Installation.
NOTE: An electrical outlet has to be available within 3 feet of the unit.

1.1 HRV 2500, HR 2.5, HEPA 3000, HF 3.0 AND HEPA 4000 UNIT INSTALLATIONS

1.1.1 STAND ALONE (PRIMARILY FOR HOMES WITH RADIANT HOT WATER OR ELECTRIC BASEBOARD HEATING.)

HEPA 3000, HF 3.0 AND HEPA 4000 UNITS ONLY

A portion of stale air coming from the register located
at the highest level of the house is exhausted to the
outside and the rest is drawn to the unit. Outside
fresh air is blended with interior air and then filtered.
Fresh filtered air is supplied by the register located
in the lowest liveable level. See figure at right.

1.1.2 CENTRAL DRAW POINT (CONNECTION TO A FORCED AIR SYSTEM)

ALL UNITS:

For this type of installation, it is not essential that
the forced air system blower runs when the unit is
in operation, but we recommend it.

NOTE: Home with multiple forced air systems

should have 1 unit on each system.

Do not connect the unit (HRV 2500, HR 2.5,
HEPA 3000, HF 3.0 or HEPA 4000) to an

y forced

air system supply duct.

CAUTION

HRV 2500 AND HR 2.5 UNITS ONLY

Stale air coming from the register located at the
highest level of the house is exhausted to the outside.
Outside fresh air is filtered and supplied by the register
located in the lowest liveable level. See figure at right.

HRV 2500 AND HR 2.5 UNITS ONLY

Stale air coming from the register located at the
highest level of the house is exhausted to the outside.
Outside fresh air is filtered and supplied to the return
(plenum) of the forced air unit. See figure at right.

HEPA 3000, HF 3.0 AND HEPA 4000 UNITS ONLY

A portion of stale air coming from the register located
at the highest level of the house is exhausted to the
outside and the rest is drawn to the unit. Outside

This filtered air is supplied to the retur

n (plenum) of

the f

orced air unit. See figure at right.

1.1 HRV 2500, HR 2.5, HEPA 3000, HF 3.0 AND HEPA 4000 UNIT INSTALLATIONS (CONT’D)

Do not connect the unit (HRV 2500, HR 2.5,
HEPA 3000, HF 3.0 or HEPA 4000) to an

y forced

air system supply duct.

CAUTION

The HEPA 4000 unit was created to meet specific requirements related to geographic locations. Take a look at the map below.
This unit can be installed anywhere in the USA, but the ventilation will be reduced in cold weather. HEPA filtration is not affected however.

NOTE:The HEPA 4000 unit is designed to assist in the management of humidity introduced into the home. In extreme humidity

conditions, the use of additional dehumidification may be required to quickly remove all excess moisture.

1.2 INSTALLATION FOR HEPA 4000 ONLY

1.2.1 GEOGRAPHICAL LOCATION

HRV 2500 AND HR 2.5 UNITS ONLY

Stale air is exhausted to the outside. Outside fresh
air is filtered and supplied to the retur

n (plenum) of

the forced air unit

. See figure at right.

air unit. See figure at right.

ALL UNITS:

To avoid cross-contamination and achieve the highest
efficiencies, the forced air system blower must
always be ON.

NOTE: Home with multiple forced air systems

should have 1 unit on each system.

NOTE: Home with multiple forced air systems should have 1 unit on each system.

Do not connect the HEPA 4000 to any forced air system supply duct.

CAUTION

Due to the potential temperature difference between the attic and the rest of the house, all unit ducts must be insulated.

CAUTION

The attic temperature must always be above 0°C (32°F).
