Open a faucet, allow air to vent and close faucet when water flow is steady. Faucet strainers and aerators should be cleaned regularly.

1. Remove shipping caps from pump ports. Some water from factory testing may spill out. 2. Mount pump vertically, with pump head down or horizontally in an accessible location. Do not compress feet with mounting screws. 3. Use 3/8″ I.D. flexible hose (preferably braided or reinforced). Use hose clamps on the slip-on hose barb connectors. 4. Install a Jabsco inlet 40 mesh strainer in an accessible location (for inspection and cleaning) between the tank and pump inlet. This strainer or equivalent is required for pump warranty to be valid. In an easily accessible location, install a switch to control electricity to the pump. Turn the pump off when not in use for extended periods, when traveling or when tank is out of water. A 4 amp fuse should be installed in the positive lead with the pump being its only load. Wire size based on total wire length, both positive and negative leads. 0 – 30 ft. #16 AWG 0 – 60 ft. #14 AWG 0 – 80 ft. #12 AWG We also stock the Par Max 1 Plus
