NOTE: These installation and maintenance instructions should be left with the unit for future reference.
INSTALLATION:
This unit must be installed in accordance with all applicable codes. This unit is not to be used for
temporary heating of buildings or structures under construction.
FOR MAXIMUM PERFORMANCE, IT IS IMPERATIVE THAT THE COOLING CHASSIS AIR DIVIDER
BE SEALED TO THE CABINET AIR SEAL. ANY LEAKAGE WILL ALLOW OUTSIDE UNCONDITIONED
AIR TO INFILTRATE AND MIX WITH THE CONDITIONED AIR.THIS CONDITION WILL DEGRADE
UNIT PERFORMANCE. ALL UNITS SHOULD BE INSPECTED FOR THIS CONDITION, AS DURING
TRANSPORTATION AND INSTALLATION THE SEALS CAN BE DISTURBED. IF REQUIRED, A LIGHT
BEAD OF CAULKING IS RECOMMENDED TO SEAL THE CHASSIS TO THE AIR SEAL TO ELIMINATE
LEAKAGE.
The unit should be provided with support inside the building in the area of the return air opening. The support
should be high enough to allow for return air provisions to the unit. To reduce the possible transmission of
sound and vibration, a resilient material such as rubber or cork should be installed between the support and
the base of the unit. All spaces around the top, sides and bottom of the exterior grille area should be caulked
and sealed to the wall, making sure that the openings for drainage in the bottom edge are not blocked.
If the optional wall sleeve is used, caulk the spaces between the sleeve and the wall. Completely fill the
clearance on all sides between the unit and the wall sleeve with a polyurethane foam sealant (follow manufac-
turer’s suggested application manual). Provide the unit with support inside the building in the area of the
return air opening. Slide the unit into the wall sleeve and fasten the unit to the sleeve with the five screws
provided with the sleeve.
NOTE: For ease of installation, install the cabinet into the wall sleeve first without the cooling chassis.
Then slide cooling chassis in after cabinet is in place.
