REFRIGERANT and HEATER HOSE INSTALLATION
1.
Refrigerant hoses should be routed over the top of the cab and down the back or side wall to the
compressor. For vehicles where the cab tilts or moves relative to the compressor ensure that the hoses
will not bind or kink in any possible cab position. Secure hoses so they will not chafe or become damaged.
Hoses must not come in contact with hot vehicle components; exhaust manifolds etc. Check to insure
hoses will not be subject to mechanical abrasions.
2.
A #12 suction hose is recommended for hoses over 10ft.
3.
On units that have the optional heater attach hoses to the unit as shown below. Secure heater hoses
along the refrigerant hoses.
4.
Route drain tubes over top of cab secure with clamps or tie-wraps. Be sure drain hoses are at no point
higher than where they leave the air conditioner. Do not let condensate drip on stairs or walkways where
it could cause a slip hazard.
