CAT-303 Installation and Parts Manual
Installation Environment
1) The distance between the unit and outside wall or other goods should be kept over 200mm.The unit should be put in well-ventilated area and its temperature is within -10℃~+40 .℃
2) Check air supply pipeline of the unit and use air source with 3~10 bar to supply for the unit. When connecting the air source, please check if there is leakage in connector for air source and ensure that a certain distance between the air hose and heat source should be kept.
3) To ensure safety. Before connecting the air source, please confirm that the air pressure adjusting valve is closed. Never point the air outlet to personnel.
Connecting Hose
1) Lift the vehicle to proper height with lifter.
2) Remove the hose between the auto transmission and radiator. See Fig.5.
3) Fill desired quantity of new ATF into the unit according to the vehicle type.
4) Connect the return hose of the unit to the outlet hose of the auto transmission.
5) Connect the outlet hose of the unit to the inlet hose of the radiator.
6) Connect the air inlet on the unit to compressed air. Please be sure that the needle valve is in the open state and the air pressure adjusting valve is in the closed state before connecting the compressed air.
Exchange
1) Keep the needle valve is in fully open state. Start the engine and meanwhile slowly turn on the air pressure adjusting valve clockwise (It is advisable to adjust up to 10PSI~15PSI, and then adjust according to the quantity of the fluid inside the new/used tank), the unit will perform exchange. In this case, the fluid level inside new fluid tank should decrease and the fluid inside used tank should rise.
2) Equal adjustment: observe the quantity of the decreased new fluid and the quantity of the increased used fluid; meanwhile adjust the air pressure valve and the fluid return valve to make sure that the level inside the used tank is equal to the new tank. If the quantity of the increased used fluid is more than that of the decreased new fluid, adjust the return valve clockwise to slow the flow speed; If the quantity of the increased used fluid is less than that of the decreased new fluid, adjust the air pressure valve counterclockwise to decrease the filling quantity of the new fluid.
3) When the color of the used fluid becomes equal to the new fluid, stop the engine and turn off the unit.
