maintaining the temperature you have 
selected for your comfort. The room 
thermostat should be in a central, draft free 
inside wall location for best operation. Do not 
place any heat producing apparatus such as 
lights, radio, etc., near the thermostat as this 
will cause erratic operation of the comfort 
system. The thermostat can accumulate dust 
or lint which can affect its accuracy. It should 
be cleaned annually. 

 

2)  Air Filter(s) -  All central air moving comfort 

systems must include air filter(s). These filters 
will be located either in the equipment or in the 
return air duct system upstream of the 
equipment. The filter(s) removes dust and 
debris from the air thus helping to keep your 
air-conditioned space clean. More important, 
the filter keeps dust and debris from collecting 
on the heat transfer surfaces thus maintaining 
optimum equipment efficiency and 
performance. Inspect and clean or replace 
filters every month. This routine maintenance 
procedure will pay big dividends in reduced 
operating cost and reduced service expense. 
Never operate comfort equipment without 
filter(s). 

 

3)  Fuses and/or Circuit Breakers-  This comfort 

equipment should be connected to the building 
electric service in accordance with local and 
National Electric codes. This electrical 
connection will include over-current protection 
in the form of circuit breakers. Have your 
contractor identify the circuits and the location 
of over-current protection so that you will be in 
a position to make inspections or 
replacements in the event the equipment fails 
to operate.

WARNING

 

a)  Do not store combustible materials or use 

gasoline or other flammable liquids or 
vapors in the vicinity of this appliance. 

b)  Do not operate the comfort equipment with 

panels removed. 

c)  Have your contractor point out and identify 

the various cut-off  devices, switches, etc., 

that serve your comfort equipment. There 
is a main switch that will cut off energy to 
your heating system. Know where they are 
so that you may cut off the flow of energy 
in the event of overheating. 

 

5)  Periodic Checkup and Service- This product is 

designed to provide many years of 
dependable, trouble-free comfort when 
properly maintained. Proper maintenance will 
consist of annual check-ups and cleaning of 
the internal electrical and heat transfer 
components by a qualified service technician. 
Failure to provide periodic checkup and 
cleaning can result in excessive operating cost 
and/or equipment malfunction. 

 

6)  Lubrication-  Direct drive blower motors are 

equipped with permanently lubricated bearings 
and do not require further lubrication. 

 

7)  Air filter replacement: An air filter can restrict 

the airflow of air to the fan coil if it is not 
cleaned or replaced periodically. When 
replacing the air filter, always replace with the 
same type and size as originally furnished with 
the unit.
