First, pre-operation preparation 1, if necessary, to pump the antifreeze thoroughly rinse. 2, check over mouth tightened. 3, open all the valves to pump the adequacy of the level. 4, adjust pump outlet pipe valve, the pump can start at the lowest pressure. 5, check the belt to make it elastic medium. Second, start 1, turn on the power start pump. 2, check the suction pressure or vacuum is normal (21 ℃ shall not exceed 24Kpa, the pressure shall not exceed 1380Kpa). 3, check the pump with or without abnormal sounds, flow is stable. 4, found pump gas block system that can not absorb liquid should do the following treatments: a, turn off the power. b, remove the pump head at the bottom center of the drain plug. c, re-start the pump system, until the liquid outflow from the drain plug port. d, turn off the power, tighten the drain plug. 5, regulating water pressure controller, until obtaining the required operating pressure and bypass pressure (pump bypass pressure shall not exceed the pump pressure limits). 6, adjusting the pressure of the safety relief valve to make the required operating pressure than the pressure of high 690Kpa. 3, Close 1, the pump suction pipe and discharge pipe disconnect. 2, remove the pump drain plug at the bottom of the center, to open the pump until all the liquid inside the pump discharge. 3, did not break off the pump and install bolt. 4, such as transmission fluid off the outside temperature is below the freezing temperature, pour antifreeze to the pump.
