and product damage or personal injury hazard may occur
without such background.
All power sources should be disconnect-
ed prior to servicing. Failure to do so may
cause personal injury or property dam-
age.
Product designed and manufactured to
permit installation in accordance with lo-

installer’s responsibility to ensure that product is installed
in strict compliance with national and local codes. Manufac-
turer takes no responsibility for damage (personal, product
or property) caused due to installations violating regula-
tions. In absence of local/state codes, refer to National Elec-
tric Code: NFPA 90A & 90B Uniform Mechanical Code.
When this unit is installed in an enclosed
area, such as a garage or utility room with
any Carbon Monoxide producing devices
(i.e. automobile, space heater, water heater etc.) ensure that
the enclosed area is properly ventilated.
The unit is designed for operation with
208/240 V, single phase, 60 Hz power sup-
ply. Aspen will not be reponsible for dam-
ages caused due to modification of the unit to operate with
alternative power sources.
Unit is not approved for outdoor installa-
tions.
This symbol indicates a potentially hazardous situation, which if not avoided,
may result in moderate injury or property damage.
Only factory authorized kits and acces-
sories should be used when installing or

-
tion. Modules are easily installed in the field using molex plugs or
can be ordered factoryinstalled. Easily accessible controls for quick
service. Electrical connections can be made from the top or left. Dis-
connect does not protrude through the wall panel. Fan time delay
relay standard for increased efficiency.
V. Electronic Circuit Board
Electronic circuit board provides 30 secs ON/OFF blower time delay
extracting more heat/cool from the coil.
VI. DX Coil

maximum heat transfer. All coils immersion tested at 500 psi then ni
-
trogen pressurized and factory sealed for maximum reliability. Liquid-
line Schrader allows pre-installation pressure testing. Available with
