CAUTION: WATER VALVE MUST BE INSTALLED PER
THE INSTRUCTIONS.
Classic Auto Air has done extensive testing on the correct method to install the water valve in order to get a
repeatable and progressive temperature control.
Locate the bottom connection from the evaporator/heater unit off of the firewall and attach a 6” piece of
5/8” dia. heater hose with the supplied hose clamp. Next attach the inlet side of the water valve using
another supplied hose clamp, (make sure the arrow on the water valve points toward the engine) Attach a
heater hose from the outlet side of the water valve and route to the connection on the water pump.
NOTE: WATER VALVE = WATER PUMP
CAUTION: WATER VALVE MUST BE INSTALLED ON HEATER LINE ROUTED TO
WATER PUMP.
NOTE: COMPRESSOR PURCHASED WITH KIT IS
SUPPLIED WITH THE CORRECT OIL CHARGE. DO NOT
