2. Intended for residential installation only in accordance with the requirements of NFPA 90B.

3. For GSVH1K, GSHH3K and GSEH3K units only: Be sure to duct air outside. - Do not intake / exhaust air into spaces with
in walls or ceiling or into attics, crawl spaces, or garage.

4. Do not run any air ducts directly above or closer than 2 ft (0.61 m) to any furnace or its supply plenum, boiler, or other heat
producing appliance. If a duct has to be connected to the furnace return plenum, it must be connected not closer than 2 ft
(0.61 m) from this plenum connection to the furnace.

5. The ductwork is intended to be installed in compliance with all local and national codes that are applicable.

6. To avoid prematurate clogged filters, turn OFF the unit during construction or renovation.

7. Please read the unit specification label on the product for further information and requirements.

NOTES: 1. The unit door is removable. To do so, remove the stopper (A) located on the

right side of the door hinge, then, slide the door out of its hinge. For servicing, a minimum
of 15’’ (381 mm) clearance from any obstruction in front of the unit is sufficient to open
the door and remove it.

2. A minimum of 8” (203 mm) clearance from any obstruction on top of the unit is required
for the ductwork radius turn.

• The joist opening needed to install the Tandem®transition must be 9 3/4” (248 mm)

minimum. Also, the maximum height of the Tandem®transition is 8 3/4” (222 mm).

See Tandem®transition end view beside.

NOTES: 1. If there is not enough space to use the Tandem®transition, the optional exterior

single hood must be installed to bring the fresh outside air to the unit.
See Section 6.8.

2. When installing a HEPA Filtration model GSFH1K, there is no Tandem®transition.

4. PLANNING THE INSTALLATION

The Guardian Plus units are versatile appliances capable of delivering filtered air (model GSFH1K) or both filtered and fresh air to
your home (models GSVH1K, GSHH3K and GSEH3K). Because each installation is different, it is recommended you take the time to
plan your installation. The three main areas to plan for are:

• Where to locate the GuardianPlus unit

• How to pick-up the air from the room and distribute the filtered or fresh/filtered air

• Where to bring fresh air from outside and exhaust stale air to outside (models GSVH1K, GSHH3K and GSEH3K).

Use the following chart to determine the appropriate installation method for the unit.

Is the house equipped with a furnace or air handler?

YES

Is there enough space to connect the unit duct(s) to the existing

furnace or air handler ductwork? (The unit duct connection can be

performed on the cold air return duct or supply air duct, at a minimum

linear distance of 2’ (0.61 m) from the furnace/air handler.)

NO

Use Stand Alone installation.

See Section 5.3.

NO

YES

The Central Draw Point

installation can be performed.

Example: Basement installation

in Section 5.4.1

OR

The Return-to-Return

installation can be performed.

Example: Crawl space installation

in Section 5.5.1

CAUTION

Do not install duct or duct connector directly above the furnace. Do not connect the plenum connection closer than 2’ (0.61m)
to the furnace, as measured along the length of the duct.

4. PLANNING THE INSTALLATION (CONT’D)

4

.1 PLANNING OF THE DUCTWORK

• Keep it simple. Plan for a minimum of bends and joints.

• Keep the length of insulated ducts to the outside of home to a minimum.(not for HEPA Filtration model GSFH1K).

• Do not ventilate crawl spaces or cold rooms.

• If the house has two floors or more, be sure to plan for at least one exhaust register on the highest lived-in level.

Use the table below to plan the flexible ducts length.

!

WARNING

Do not attempt to recover in any ways the exhaust air from a dryer or a range hood. This would cause clogging of the filters
and recovery module (if applicable); this is also a fire hazard. Not following this warning will void the warranty.

5. TYPICAL INSTALLATIONS

Installations may vary according to the model number, the product orientation (vertical or horizontal) and the location in the home where
the unit is installed. Use the following illustrations as guidelines to help you decide the appropriate installation.

The unit allows for multi positional mounting (vertical or horizontal). It may be hung to the joists (preferred method),or it may be laid down
on one of three surfaces, and installed either vertically or horizontally.
NOTE: For more details, see Points 5.3 and 5.4 in Section 5 INSTALL THE UNIT.
In every case, bathroom fans and a range hood should be used as spot ventilation to exhaust stale air. Also, for homes with more than
one level, we recommend placing one exhaust register at the highest lived-in level.
There are threer installation methods: Stand Alone, Central Draw Point* and Return-to-Return*.
* Different connections to a forced air system.
Multiple furnaces or air handlers may require installation of GuardianPlus on each system for maximum IAQ benefit.

NOTE: A grounded three-prong electrical outlet has to be available within 3 feet from the unit.

5.3 STAND ALONE INSTALLATION

(Primarily for homes with no central air mover or equipped with wall furnaces, radiant hot water or electric baseboard heating.)

5.3.1 BASEMENT

• Ideal for homes without a central
furnace in the basement. Allows
filtration and a better air circulation
throughout the house.

• Easy access to perform the periodic

filter maintenance and servicing.

• Offers an ambient temperature

above freezing (32°F - 0°C).

• The HEPA Filtration model GSFH1K

has no connection to the outside,
so all parts encircled are not required.

INSTALLATION CONSIDERATIONS:

• Installing the unit near an exterior

wall will shorten the length of the
insulated ducts (not necessary for
HEPA Filtration only model GSFH1K).

• If a HEPA Filtration Fresh Air &

Heat Recovery Ventilation model
GSHH3K is installed, a water drain
must be close to collect the run-off.

Only for the models GSVH1K,

GSHH3K and GSEH3K that

use fresh outside air.

VH0039

Drain required only for the
GSHH3K model.

5.3.2 GARAGE CLOSET

• Ideal for homes without a central

furnace, or limited space applications,
allows filtration and a better air
circulation throughout the house.

• Easy access to perform the periodic

maintenance (twice a year).

• The HEPA Filtration model GSFH1K

has no connection to outside, so all
parts encircled are not required.

Only for the models GSVH1K,

VH0046

GSHH3K and GSEH3K that

use fresh outside air.

CAUTION

When the ambient temperature for the unit location is below freezing (32°F - 0°C), the unit must run continuously to prevent
condensation.

INSTALLATION CONSIDERATIONS:

• Installing the unit near an exterior wall will shorten the length of the insulated ducts

(not necessary for HEPA Filtration model GSFH1K).

• If a HEPA Filtration Fresh Air & Heat Recovery Ventilation model GSHH3K is installed, a water drain must be close to collect

the run-off.

• All ducts must be insulated.

• For the HEPA Filtration, Fresh Air & Heat Recovery Ventilation (GSHH3K) and the HEPA Filtration, Fresh Air & Energy

Recovery Ventilation (GSEH3K) models only, if the ambient temperature around the unit drops below freezing (32°F - 0°C),
go to Section 6.12 (Low Temperature Applications) for instructions on drain line protection (GSHH3K only) and other cold
environment installation details.
