Product Water Outlet Connection
The product water outlet on the CPM is a barbed fitting for connection to
3
/8" ID hose. The
fitting is attached to the diversion valve that is mounted on the back of the CPM. The
product water outlet hose will carry water to the storage tank. Use only food-grade hose
(suitable for carrying fluids for human consumption and capable of withstanding working
pressures of 50 PSI). Suitable hose is available from your dealer (P/N 210-005).
Route the hose to the water storage tank using the most direct path. Secure the hose so
it will not be abraded or pinched. The storage tank must be vented to atmosphere and the
product-water hose must feed into the top of the tank so that the product water can flow
freely into the tank with no restriction or back pressure. Excessive back pressure will
reduce or stop the flow of product water from the CPM.
If the top of the storage tank is more than 15 feet above the CPM, a pump will have to be
used to help lift the product water. Contact a dealer or the factory for details. Use a
3
/8"
hose barb fitting and suitable adapters, if necessary, to connect the product water hose to
the storage tank. These fittings are available from your dealer. Secure the hose to the
barbed fittings using suitable hose clamps.
Waste Product Water Outlet Connections
On the Control Panel is a barbed fitting for
3
/8" ID hose. A hose connected to this fitting
will carry rejected product water overboard. Install a suitable discharge fitting above the
vessel's water line and connect the
3
/8" ID hose. Secure each hose end with hose clamps.
It is very important that no valve be installed in either of these lines since any restriction
could damage the RO membrane.
Input 12VDC Power Connection
A separate source of 12 VDC power is required for the Aqua-Pac integrated desalinator. The
power should be a 12 VDC-20 amp circuit protected by a 20-amp circuit breaker. (This
circuit is usually connected to the boat's main DC electrical panel).
This input power is connected to the "12 VDC IN" terminals on the Pre-Filter Relay Module.
Use 12 AWG wire for runs of up to 25 feet. Runs of over 25 feet require 10-gauge wire.
Protect the wire feed with a circuit breaker in the positive leg of the feed as close as
possible to the main power panel or bus. Be extremely careful to connect the positive lead
to the "+" terminal and the negative lead to the "-" terminal. Label the circuit breaker
"DESALINATOR" or "WATERMAKER".
Connecting Electrical Control Cable Between CPM and Pre Filter Pack
A 25' length of 6-conductor cable is supplied for connection between the terminal strip on
the back of the CPM and the junction box on the side of the pre filter pack.
Watermaker Pre-Filtration Module Installation
The Pre-Filtration Module should be mounted slightly above the source level (waterline) on
marine installations since most of the components are made of plastic and failure of a
component could result in flooding of the vessel.
Select a mounting site that will support the weight of the PFM when filled with water, will
allow easy access for maintenance, and that will have enough clearance below for
removing and reinstalling the filter bowl. If the top of the PFM has to be mounted more than
3 feet above the source level, a feed-water pump will be required or the PFM filter element
