Intended Use - Dometic SeaLand MasterFlush MF 7200 Series Operation Manual

Caution! Hazard of Flooding
If the toilet uses fresh water for flushing and is connected directly or indirectly to a
shoreside municipal water system at ANY time, shoreside water connections MUST be
disconnected if the boat is unattended (even if boat is unattended for a brief period) .
Failure to do so can result in flooding which can cause loss of property and life .
Caution! Hazard of Flooding
Before beginning any work on this product, be sure that all electrical power to the unit has
been turned off and that seacocks are in the CLOSED or OFF position . Failure to do so can
result in flooding which can cause loss of property and life .
Caution!
Overfilling the holding tank can create serious damage to the sanitation system, such as
rupturing the holding tank and releasing tank contents into the bilge . To prevent this
possibility, Dometic recommends using a "full" tank shut-down relay . The "full" signal from
the holding tank can be generated by an optional Dometic DTM01C tank monitor or DTM04
four-level tank monitor system .

macerator toilets:
• Adjustable toilet base. Toilet base can be positioned so that macerator pump housing
extends in any direction from the center of the toilet .
• Floorplan flexibility. Macerator pump allows toilet to be located up to 40 ft . (12 .2 m) away or
up to 4 ft . (1 .2 m) below holding tank or other discharge line destination .
• Self-priming sea water pump (sea water flush version only). Integral pump for sea water
flush is self-priming with a maximum lift of 4 ft . (1 .2 m) .
Automatic "full tank" shut-down (optional installation - tank level monitor and shut-down relay

tion system, electrical power to the toilet shuts off when the holding tank is full . This safety feature
prevents overfilling the holding tank, which may cause damage to the boat .
