Pre-Operating Instructions: Connecting Water Inlet Hose Use commercially available hose, hose joint, and clamp. The water inlet hose must be of continuous structure and be rigid. The length of the hose should be no more than required. The effect of suction is greatest at shorter distances from the water surface. Suction time varies with the length of the water inlet hose.
Pre-Operating Instructions: Connecting Water Outlet Hose Use commercially available hose, hose joint, and clamp. A short hose with a big diameter will provide the best performance. A long hose with a small diameter will increase flowing resistance and decrease the power output of the water pump.
