Aqua Flo Medium-Head Dominator Pump Diagram Aqua Flo Dominator Pump Diagram PRIMING PUMP At initial start-up, pump must be primed by filling hair and lint trap with water. To prime pump, remove cover from hair and lint trap: fill pump and suction trap with water. Replace cover (make sure the O-ring is in place) and tighten lock ring. Pump will now prime, with priming time depending upon lift and horizontal distance of suction piping. CAUTION: Do not remove hair and lint strainer lid while pump is running or under pressure! Lid is held in place by a lock ring which can be removed or tightened by hand. Basket must be kept clear of leaves and debris at all times. CLEANING BASKET Turn off motor. Remove lock ring by rotating counter clockwise. DO NOT USE TOOLS. Remove lid. Remove basket and empty debris. Replace basket, fill with water, replace lid and lock ring securely to prevent air from entering and tighten. DO NOT USE TOOLS. Turn on motor Open air-relief valve on top of filter until steady stream of water comes out. NOTE: If pump is installed below water level of pool, close return and suction lines prior to opening hair and lint pot. Make sure to re-open valves prior to operating. DO NOT RUN PUMP DRY! Always maintain proper water level in pool. If water level falls below skimmer intake, pump will suck air. Pump is equipped with a maintenance-free, heavy-duty mechanical seal. Damage will occur if pump runs dry, and warranty will be voided. TO PREVENT FREEZING Drain liquid from pump through plug at bottom front section of volute. It is recommended to apply a good rust inhibitor into liquid end to prevent corrosion. Be sure motor is kept dry and covered. In mild climate area, when freezing may occur, run pump and filter equipment continuously to prevent freezing.
