When exchanging air with outside:
ZONE A: GSHH3K unit recommended*
ZONE B: GSEH3K unit recommended
* In ZONE A, the GSEH3K unit may be used, but below 16°F,
the duration of exchanging air with outside will decrease.

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.
Example: Basement installation
in Section 5.4.1
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.
The Return-to-Return
installation can be performed.
The Central Draw Point
installation can be performed.
Is the house equipped with a furnace or air handler?

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.)
