APPLICATION The Maxi System has been designed to simplify the installation of pressurised fresh water systems in small vessels. It is supplied complete and ready for installation. It incorporates a stainless steel and all the components necessary for a reliable supply of hot and cold running water on board your vessel - at the turn of a tap. INSTALLING YOUR MAXI-SYSTEM. Install the unit in a dry and accessible location in the engine compartment or elsewhere.. Keep the inlet pipe from the water supply tank as short as possible ( metres maximum). The is self-priming, and may be mounted above the level of the water supply. Maximum vertical suction lift is metre. 3. Fix the plate firmly to a rigid surface. The may be mounted horizontally or vertically: if vertical, the head should be BELOW the motor.. The inlet pipe bore should be at least ½. Use rigid or reinforced pipe that will not deform or collapse under suction conditions. 5. Use the recommended Hep O fittings (see drawing) to connect the inlet and outlet pipework into your system. Inlet: CW93W or CW9W 90º connector (not supplied) Outlet: Hep O pipe (not supplied) HEP O PUSH-FIT PIPEWORK IS STRONGLY RECOMMENDED light-proof to discourage growth of algae tough, flexible, ultra-simple to install joints remain fully watertight, even when rotated under pressure suitable for hot and cold water frost protected to 0ºC quiet, non-reverberating low heat loss. Discharge pipe of at least ½ bore is recommended: a smaller bore will reduce the flow rate obtained at the outlets. 7. Make sure that the motor voltage corresponds to your supply voltage. Use cable of the recommended size: Note: Cable length is for line and return i.e. twice the run distance. If in doubt use the next largest wire size.

OPERATION. Check that the water supply tank is filled, and that the inlet pipe to the MAXI-SYSTEM is connected and airtight. The pressure in the accumulator tank has been pre-set and does not require adjustment.. Open all the taps and other outlets in the system. This allows the to self-prime easily. Follow the same procedure whenever the is restarted after running out of water. 3. Switch on the power at the master switch. The should start and prime itself, and water should flow from the open outlets within a short time.. Allow air to clear itself from each open outlet, then close it. The should run for a short period then stop automatically. The system is now operational. TROUBLE SHOOTING Problem Possible cause Action Pump does not prime: motor runs but no discharge Motor fails to start when switched on Pump fails to turn off with all outlets closed Pump runs intermittently with all outlets closed MAINTENANCE Restricted or blocked inlet or discharge pipe. Air leak in inlet pipe Dirt under valves. Pump diaphragm leaking Supply tank empty Loose wiring connection No power in circuit Blown fuse Failed pressure switch Supply tank empty Inlet or discharge pipe leak Insufficient voltage at Failed pressure switch Dirt under valves allowing leakage to suction side of Leaking pipework on discharge side of Check pipes Check for leaks Check valves Check diaphragm Fill tank Check wiring Check power source Check cause and replace Replace pressure switch Fill tank Check for leaks and repair Check supply voltage and cable size Replace pressure switch Check valves Check pipework Your MAXI-SYSTEM is designed to operate without frequent maintenance, but the following procedures will help to ensure that the system gives you lengthy and trouble free service.. Check the inlet strainer periodically, and clean if necessary.. Every months, check the pressure in the accumulator tank. Disconnect the electrical supply, open a tap until flow ceases and unscrew the end cap from the accumulator tank to expose the air valve. Use a car tyre pressure gauge to check the pressure in the tank. It should be approximately 8lb/in (0.55bar). Air may be ed in to raise the pressure if necessary, using a suitable foot or hand. Restart the system as detailed above.
