Cruise N Comfort HD 12L User Manual

1. Locate the area where the unit will be mounted and double check that there are NO
obstructions. Make sure that the location allows for the cold air to return to the units
evaporator. The unit has 4 large 3/8 “ holes punched into the stainless steel plate chassis.
We recommend you through bolt this unit to the floor using at least 3/8 grade #5 bolts with
lock nuts and fender washers. This unit is around 70 lbs very heavy so secure it
accordingly !!!
2. Find a suitable location for the remote condenser. This condenser is not designed to be in
front of a radiator, it will block the air flow and cause over heating. The remote condenser must be installed so
air can enter the front of the condenser and then is pulled thru the fan. It is a good idea to have the fan toward
the back of the vehicle so when traveling down the road air can easily go thru the condenser. The unit can be
mounted standing up with the large port being higher than the small port and the hose exiting out the side not
the top. Remote condenser can be laid almost flat, always maintain a minimum of a 15 degree angle so that
the large port is always higher than the small.
