WARNING
Only potable water from a reliable source should be used in these tanks. Do NOT store water in the tanks for more than two weeks. Please ensure you
sanitize, flush and drain the water tanks before using and a minimum of every 6 months thereafter or if you suspect there’s an issue with the quality of
your water. Do NOT use bleach to sanitize the tanks as they are stainless steel and it will cause corrosion. Please see the OPUS Care & Maintenance sec-
tion of this manual for more information on sanitizing your water system. Failure to maintain your tank can result in death or serious injury.
12v WATER PUMP
Your water system is connected to the 12v water pump which can be switched on via the main
control panel. Your two potable water tanks may be used to supply water to the bathroom including
the shower and sink as well as the kitchen sink. The potable water tanks also supply water to the
Truma hot water system AND the flushable toilet (see each section on the following page for more
information on these systems). The water pumps are pressure operated, so once the main power
switch is turned on at the control panel the pump will prime the system and as soon as you turn the
tap on the water will flow. Once the tap is closed, the pump will turn off until the tap is turned back on.
WARNING
Please turn off your pump at the main control panel when the water system is not in use as they will continue to use battery power when they are
turned on but not in use. Do not run your water pump when the tanks are empty as this could cause the damage to the water pump and circuit.
