Use this procedure when starting a new watermaker for the first time and whenever the sys-
tem has been pickled or cleaned. On new systems the green tag and washer prevent the
pressure relief valve from being closed and remind new owners to keep it open.
Avoid running the Catalina system if the vessel is in contaminated water. The system should
be fully tested before leaving port. If the location or weather prevents proper testing, refer to
Dry Testing with an Artificial Ocean on page 42.
Warning! Damage may occur if the purge sequence is bypassed and the membrane is
pressurized with storage chemical in it.
First check:

Thru-hull inlet and the brine discharge valves are open.

All of your hose connections are tight.

The pressure relief valve is open 1/2 turn (or tag and washer are still in place).

The toggle switch on the MPC control box is set to the Auto position.

There are at least several gallons of water in your fresh water tank for priming and the
ship’s pressure water system is on.
