Ensure that the CHEB (Compressor, Heater, Evaporator, Blower) is placed so that all electrical wiring connections and
refrigerant ports are easily accessible for future maintenance and service.
NOTE: If the CHEB will be installed in a tight-fitting area, it is best to cut all holes and install supply and return air grilles before
installing the CHEB unit, so that nothing will interfere with hole saws or drilling locations. If so, see "Part 5: Duct and Grille
Installation" on page 13 before continuing with this section.
Tools required for this step:
•
Reciprocating Saw
•
Drill
•
Hole Saws: 1-5/8", 1-7/8", 2-1/2", 4", 4-1/2"
•
Utility Knife
•
Drill Bits: 1/8", 5/32", 9/32"
•
Nut Drivers: 1/4", 3/8", 5/16"
•
Phillips Head Screwdriver
•
Open End Wrenches
•
Light Machine Oil

NSTALLATION
1.
Cut out the template found on a panel of the cardboard box in which the unit was packed (or, the template may be
printed and packed inside the box). See Figure 2.
2.
Tape template to the floor to determine where holes will be drilled for line sets, and condensate drain. Double check
underneath the cab to ensure you will not cause damage to anything such as structural members, hydraulic,
air, or electric lines under the floor.
3.
Before drilling the correct size holes, drill a small pilot hole in each location, to see under the truck where the drill bit is
coming through. This is to confirm the location is clear of all obstructions.
4.
If floor mat is present use a 2-1/2" hole saw to cut through the floor mat ONLY in order to remove that area of the floor
mat.
5.
Use hole saws to cut each hole. You will need to cut (2) 1-7/8" holes for refrigerant line and condenser cord, and a
single 1-5/8" hole for the P-Trap.
