Your equipment is covered by a LIMITED WARRANTY against
defects in material and workmanship.
This is a vertical, wallmount unit designed for many different
applications in both residential and commercial settings. It is self-
contained and arrives completely assembled, factory-charged and
wired. The unit is 100% run-tested at the factory to ensure proper
operation. Your unit is supplied with high-quality copper tubing and
enhanced aluminum-finned coils for high heat transfer efficiency
and long life. The unit cabinet is constructed of G-90 galvanized
steel. All exterior surfaces are finished with a baked-on polyester
coating. This will provide excellent corrosion protection in most
applications. However, if the unit is installed in an area with a
corrosive atmosphere, such as near an industrial plant or on the
seacoast, additional coating should be considered to extend the life
of the coils and cabinet.
This unit was designed for up to 105ºF of ambient temperature.
A thorough inspection of the shipping container should be made
immediately upon receiving your unit. Look for any punctures or
openings. If it appears as if damage has occurred, it should be
noted on the freight bill before signing. The delivering carrier should
be contacted immediately to inspect damage, and no installation
work should begin until this inspection is completed.

If heating and cooling functions are controlled by separate
thermostats, turn the furnace thermostat to the “OFF” position
during the cooling season to prevent simultaneous operation of
the heating and cooling systems. Reverse the procedure during
the heating season.
If the same thermostat controls both heating and cooling
functions, set the thermostat to either HEAT or COOL as desired.
Set the desired temperature on your thermostat dial and set the
fan switch to “ON” (for continuous air circulation) or to
“AUTOMATIC” (for air circulation only when the air conditioning
system is operating).
IMPORTANT: Wait at least three (3) minutes after turning the
air conditioner off before trying to restart. If an attempt is made to
start the compressor before the refrigerant pressures are
equalized, the compressor motor may trip on its overload. An
additional waiting period will be required before restarting.
1. Always install and keep filters clean. Check filters every 2 weeks.
Clean or replace if necessary. The factory-installed filter is
located behind the center front access panel.
TO CHANGE SYSTEM FILTER:
A. Turn the power to the unit off at the unit disconnect. The
disconnect is located on the front of the V Series unit behind
a small access door.
B. Remove the front center access door from the unit.
C. Remove and replace the filters with the type and size
indicated in the table below.
D. Replace the access door and turn on the power to the unit.
NOTE: If your system has a filter grille installed in the return air
opening, the unit filter should have been discarded during
installation.
The filter installed into the return air grille assembly should be
replaced with the same size and type provided with the grille.
If your system is equipped with a fresh air intake, the filter for the
fresh air assembly is accessed through the front center panel. The
filter is a permanent washable type.
