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 contac-
tor 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 fi tting and rim of toilet could EVER be in a position below the waterline.
DANGER:
Failure to use a Vented Loop in raw water pump installation sites can lead to water fl owing into the toilet from the outside (siphoning)
which can cause loss of property and life!
