Raw water considerations

The Raw Water pump must be securely mounted in a dry, well-ventilated area. It
■
should be mounted not more than 6' at any time above the heeled waterline.
DANGER: The Raw Water pump must be powered by the toilet relay module. Use of
any pump that draws more than 15 amps requires installation of a pump contactor
relay. Do not wire pump directly to a D.C. power source so that it is controlled by its
pressure-activated switch. If a leak were to occur when wired directly, the pump
would run continuously and create risk of sinking of the boat and loss of life.
■
An in-line strainer MUST be installed to protect the system. Failure to use an in-line
strainer may void product warranty.
■
A Vented Loop of proper diameter MUST be installed if – UNDER ANY
CIRCUMSTANCE or CONDITION (including heel trim or load):
• Toilet is connected to a through-the-hull fitting and rim of toilet could
DANGER: Failure to use a Vented Loop in raw water pump installation sites can lead
to water flowing into the toilet from the outside (siphoning)
which can cause loss of property and life!
