Heater-Hot Water - Regal 53 SC Owner's Manual

HEATER-HOT WATER

The hot water heater features an twenty gallon capacity and
has recirculating ability to keep water warm during cruising.
This is accomplished by a set of hoses connected between
the hot water tank and the circulating engine water pump.
Engine coolant runs through a heat exchanger which keeps
the tank water warm when the engines are running.
To initially fi ll the hot water heater, ensure the boat's fresh
water tank is full. When the tank is full water will be ejected
from the deck vent. At the DC side of the main ship's AC/
DC panel, turn the fresh water pump to the "on" position.
Make sure the water heater is full of water by opening
a hot water faucet until a steady stream fl ows out. At
this point with the generator running or the shore power
connected, switch on the hot water heater at the AC side
of the ship's service panel. The heating element will now
begin to heat the hot water tank.
Should the hot water heater reset button need to be
activated, turn off the hot water breaker at the AC side of
the main control panel. Then remove the panel cover to
expose the reset button. Press the red reset button. After
refastening the access panel, energize the hot water breaker
to continue the system operation.
Should the need arise there is a drain valve located at the
rear of the heater. Always turn the hot water breaker to the
"off " position before opening the drain valve. Make sure
the water is cold before attempting to open the valve. The
valve runs through the shower sump pump and then
overboard. Never try to adjust the thermostat or open the
drain valve before turning off the AC breaker. Contact a
marine professional for further information.
There is a T and P relief valve on the aft water heater. If
the unit temperature rises above the specifi ed temperature
of the T and P valve the unit will release the hot water
into a hose and subsequently exits a thru-hull fi tting. Turn
the hot water breaker off and determine the cause of the
overheating condition. Use exact replacement parts.
