Notes

Use primary and secondary raw water filters .
Raw water pump MUST NOT be demand-type . Pump is controlled by flush switch .
Install vented loop as shown . It must be equipped with integral check valve that permits air into line to
prevent siphoning .
Dometic macerator toilets can operate with an
onboard pressurized freshwater system with a
minimum flow rate of 2 .0 gpm (7 .6 lpm) at the
toilet . Onboard fresh-water demand systems
include a water pump that automatically draws
water from a water storage tank when a valve
anywhere in the piping system is opened .
Dometic macerator toilets can flush on seawater but require a separate pump for this purpose . The
pump is activated by the signal from the toilet’s flush switch . If the raw water pump draws more
than 18 amps of current, a 12 or 24 V DC electrical relay must be installed .
Dometic 8100 series toilets are equipped with
an electrically operated water valve and an
in-line check valve to prevent contamination of
onboard potable supplies .
