Drain Connection
The HRV may produce some condensation during a defrost
cycle. This water should flow into a nearby drain, or be
taken away by a condensate pump.
The HRV cabinet has pre-punched holes for the drain
(see below). Insert the drain spout through the hole in the
drain pan. Be sure to install the "O ring" which seals each
spout to the pan. HAND TIGHTEN the washer and lock nut
which hold the drain spout in place.
Construct a P-Trap using the plastic tee connector. Cut two
lengths of 1/2" drain hose (not included) and connect the
other ends to the two drain spouts. Position the "T" fitting to
point upward and connect the drain line. Tape or fasten base
to avoid any kinks. Pour a cup of water into the drain pan of
the HRV after the drain connection is complete. This
creates a water seal which will prevent odors from being
drawn up the hose and into the fresh air supply of the HRV.
Adjustable grilles can be used to balance the flow rates into
and out of various rooms. The grilles should not be adjusted
after balancing the unit.
Grilles or diffusers should be positioned high on the wall or
in the ceiling. Kitchen Exhaust grilles must never be
connected to the range hood. They should be installed at
least 4 feet (1.2 m) horizontally away from the stove.
Field supplied balancing dampers can be installed external
to the unit to balance the amount of stale air being
exhausted with the amount of fresh air being brought into
the house. Refer to Air flow Balancing section.
ZRT Zone Registers
are used to balance exhaust flow
rates and provide the ability to “boost” the flow rate from
each zone as needed.
The Algrille is a round, fully adjustable grille that provides
superior, quiet air distribution.

The HRV and all condensate lines must be

maintained above the freezing point or freeze
protection must be provided.
