Install Instructions

Location of the HRV for Mounting
The HRV must be located in a heated space where
the surrounding air temperature does not fall
below 60°F (16°C). The unit must
be mounted
level (horizontal) to obtain proper drainage of
water from the heat exchange element and drip
pans. The warranty will be void if these conditions
are not met.
Typically, the HRV is positioned close to an outside
wall or the roof to simplify the connections and keep
the length of insulated ducting required for the
fresh air intake to a minimum.
A minimum clearance of 30 inches (76 cm) in front
of the HRV is recommended to service the heat
exchanger cores and th
e filters. The HRV may
be mounted on an equipment platform providing
the drain hoses are clear and there is sufficient
space to open the doors for servicing.

rods and "U" channel

Operating the HRV without a
Main
Control
and
Adding Dry
Contact Controls
A jumper must be in place between 2 (ON)
and 3
(RED)
on the Terminal Block
to
activate the HRV for timers and/or dry
contact
controls.
Adding Dry Contact Controls
Low Speed - A jumper between 2 (ON)
and 1 (LOW) initiates low speed ventilation.
High Speed - A jumper between 2 (ON)
and 6 (HI) initiates high speed ventilation.
Dehumidistat - A dry contact for a
dehumidistat is connected between 2 (ON)
and 10 (BLK).
The
Terminal Block
(located on the HRV)
The HRV must have a Jumper in
place between
2 (ON) and
3 (RED)
on
the
Terminal Block when
installing the unit without a Main
Control.
