The outdoor and indoor conditions of your area will determine the frequency of filter
changes. Temspec recommends that the filters be changed every 3 months as a rule-of-
thumb. Note that dirty filters adversely affect the overall performance of the unit.
To change the filters, open / remove the filter access panel by loosening the Philips head
screws. On the VLC series units, simply slide out the old filters and replace them with the
new ones. On the VHC series units, unclip the filters. Be sure to note the airflow direction
that is marked on the filter(s).
The following are the recommended steps to cleaning the condenser coil.
CAUTION
:
Disconnect
power at the remote circuit breaker before servicing the
unit.
1.
Clean debris and leaves from between the blades of the exterior louver.
2.
VLC series:
Unfasten the removable section of the louver from the exterior side
of the building.
VHC series:
Remove the unit ventilator return air access panel and condenser
access panel from inside the room.
3.
Vacuum the entering air face of the condenser coil using a soft bristle
attachment. Be careful not to bend any of the aluminum fins on the coil.
4.
Use a foaming coil cleaning chemical (such as “Foam-Brite” from NU-CALGON,
product# 4178-08,
www.nucalgon.com
). Follow the manufacturers instructions
for safe handling and personal protective equipment.
WARNING: Do NOT use condenser coil cleaning compounds on the evaporator or
hot water coils.
WARNING: Do NOT use chlorine based cleaners or anti-fungal treatments on the
aluminum fins of any coil.
Depending on the wind conditions and building pressurization, a portable fan
may be required in the room to ensure that the fumes are properly exhausted out
of the building (VHC series only).
