5. TYPICAL INSTALLATIONS (CONT’D)
- 12 -
5.3 STAND ALONE INSTALLATION (CONT’D)
(Primarily for homes with no central air mover or equipped with wall furnaces, radiant hot water or electric baseboard heating.)
5.3.3 ATTIC
• Ideal for homes without a central
furnace, or limited space applications,
allows filtration and a better air
circulation throughout the house.
• Only one partition to go through to
install the registers.
• No visible ducts.
• The HEPA Filtration model GSFH1K
has no connection to the outside,
so all parts encircled are not required.
CAUTION
When the ambient temperature for the unit
location is below freezing (32°F - 0°C), the
unit must run continuously to prevent
condensation.
VH0054
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.
• 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.
Only for the models GSVH1K, GSHH3K
and GSEH3K that use fresh outside air.
Drain required only for the GSHH3K
model .
5.4 CENTRAL DRAW POINT INSTALLATION
(Connection to a Forced Air System)
5.4.1 BASEMENT
• Simplified installation by using the
home existing ductwork to supply
filtered air throughout the house.
• The central draw point should be
located in the main area where
most of the pollutants are produced.
• The furnace/air handler does not
need to run continuously.
• Easy access to perform the periodic
maintenance (twice a year).
• Offers an ambient temperature
above freezing (32°F - 0°C).
• The HEPA Filtration model GSFH1K
has no connection to 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.
VH0040
Only for the models GSVH1K,
GSHH3K and GSEH3K that
use fresh outside air.
Drain required only for the GSHH3K.
