Service and Maintenance
Filters
Open front service door to access the filters located in
both supply and exhaust air streams. Note to remove and
install filters, it may be easier to first remove the core(s).
Refer to HRV Core.
The filters are designed to stop large particles from enter-
ing in the core. The filters are fastened in place by a met-
al spring rod. To remove filters from core(s) simply pull
the rod from one end, outward until free from core lip,
and remove.
Only use warm water with a mild detergent to wash the
filters. Do not use harsh chemicals.
The time between filter service will depend on the applica-
tion the HRV has been installed in. It can be as often as
one - two months or at the very least, cleaned every six
months.
Condensate Drains
The condensate drains consist of two drain pans which
may collect water after the HRV initiates a defrost cycle,
and a drain line to remove the condensate.
Maintenance on this portion of the system should be done
as often as possible and should not exceed six months.
Note bacterial growth in standing water is a major con-
cern to healthy indoor air quality, and should be avoided
whenever possible.
To clean these components, open the front service door
and flush the pans with water. Ensure that the pans drain
completely and in a reasonable amount of time. Note if
the water does not drain right away, check for blockage in
the drain line, also check that the drain line has a good
slope to it. (1/8 - 1/4” per foot)
The drain line itself should have a “P” trap in it below the
HRV which is to be filled with water to prevent odors or
gases from entering back into the unit.
Duct Work
It is a good idea to inspect ducting, outside weather
hoods (wall caps), and grilles for blockage and dirt
buildup, at least every six months.
Outside weatherhoods should be protected by a bird
screen which can plug up with debris. Also, it is a good
idea to visually confirm that the fresh air supply is free
from any sources of contamination, such as other vented
combustion equipment added after the fact.
Damper Motor
The damper motor, (if applicable) is a self contained mo-
tor and does not require service. The damper door at-
tached to the motor could use a little lithium grease on
the shaft opposite the motor, where it enters its holder,
once every two - three years.
General Maintenance
As a final step in a routine maintenance schedule, it is a
good idea to confirm operation of the system, checking
speed control functions and remote control operation, if
applicable.
Wipe the inside of the cabinet to remove dust and cob
webs as needed.
It is a good idea to keep a service/maintenance log of the
unit.
