Servicing your HRV on a regular schedule will result
in optimum operating efficiencies and prolonged life
of the equipment.
Due to numerous applications in which this
equipment can be installed, it is difficult to predict
servicing intervals. In certain situations where there is
heavy smoke, servicing the equipment every one -
two months may be needed; whereas ventilating a
meeting room for carbon dioxide may only need
service every six months to a year.
Motor
Access to the motor is through the front service doors.
Note heat exchanger core can be removed to provide
more room. See
CORE
in this section.
The motor is a permanent split capacitor type (PSC)
which uses a sleeve mechanism to steady the shaft.
Core
The heat exchange core is accessible through the
front service door. Special care and attention should
be given to this component as the edges may be
sharp, and the core itself susceptible to damage if
dropped.
When removing the core, the location it is removed
from should be noted.
The core is removed by carefully pulling the core
outward from the unit, sliding it evenly along its “H
channel” supports found in each corner of the core.
Note the core may have some resistance when
sliding out. Avoid tilting the core as this will result
in its edges catching the H channel and temporarily
preventing its removal.
In most cases, washing the core in a mild detergent
and warm water will be all that is needed to
completely clean them. Do not use harsh chemicals
as this may cause corrosion in the HRV. The time
between core service will depend on the application
the HRV has been installed in. It can be as often as
one - two months or at the very least, cleaned every
six months. When reinstalling the core you must
note foam location and drip edge location for proper
core placement. See diagram below.
With the core in its proper position, place the bottom
flange,(approximately 1/4”) into its H channel
support, then place the left side, the right side and
finally the top flange into place in the same fashion.
Once all four corners are in place, push the core
evenly into the cabinet until it reaches the back. Be
sure the drip edges are overlapping the drip trays.
Note the core will protrude slightly out from the front
of the cabinet, this is so the access door, when
closed, ensures a tight fit.
