Coil Freeze Protection (Auto Defrost)
:
The dehumidification coil (evaporator) is equipped with a low temperature freeze
thermostat; if the coil temperature is reduced to the point of ice buildup, this ther-
mostat will open the compressor control circuit while allowing the fan to continuing
running� Once the coil has returned to normal conditions the control will close and
allow the compressor to re-start� The prevailing conditions of the return air, tem-
perature and humidity, will determine the length of this cycle�
High Efficiency Air Filter:
The Comfort-D is supplied with a 2” pleated high efficiency air filter. The 2” filter is
rated MERV 11, and is more efficient than standard air filters and is able to catch
much smaller particles that can aggravate allergies� Operating the unit with a dirty
filter will reduce dehumidifier capacity and efficiency and may cause the compres
-
sor to cycle off and on unnecessarily� Under normal operating conditions, the
filter will last approximately 6 months. However, in high particulate concentrations
more frequent replacements may be required. It is recommended that the filter be
inspected regularly for the first three to four months to determine the loading and
correct replacement intervals� Your installation contractor should be contacted for
assistance�
To access the air filter, remove the filter access panel from the Front or Back side
of the unit, marked “Filter Access”. The filter should be readily visible and can be
removed by pulling it straight out of the unit�
Replacement filters can be purchased from your installation contractor or ordered
from the factory if a local representative is not available� DO NOT operate the unit
without the filter, or with a less effective filter than originally supplied. The heat
exchange coils inside the unit could become clogged and require disassembly
to clean. FAILURE TO MAINTAIN SERVICE AND CLEAN FILTERS WILL VOID
WARRANTY�
Oiling & Lubrication:
The fan motor is factory lubricated and sealed, and no further oiling is required�
There are no other components requiring the addition of lubricants�
Optional Fresh Air Ventilation (OSA):
If your system includes the optional fresh air system, it will have an outside air
intake� Check and clean the screen on the outdoor fresh air intake seasonally�
The intake screen must remain clear of any debris that could restrict airflow into
the system� This intake should never be located where undesirable fumes, gases
or odors make be taken up by the intake� In all cases local codes prevail as to the
location of fresh air intakes�
