Cosmetic Care & Maintenance
FRESH WATER SYSTEM
The fresh water system in general requires very little
maintenance.
1. See the equipment operation chapter defining the
recommended seasonal disinfection procedure.
2. The fresh water filter needs to be cleaned periodically.
Simply remove the hose clamp and unscrew the fresh water
filter to access the screen. Rinse the screen off to remove
any foreign debris. Be sure to use teflon tape on the pump
fitting threads before installing the filter. Reinstall the
components and check for leaks. See the illustration.
3. Periodically check all fittings for leaks.
4. In colder climates, use Winterban or its equivalent in all
the fresh water system components after draining the
system.
HOT WATER HEATER
A. The most important maintenance factor with the hot
water heater is it should be treated with Winterban in colder
climates. Use the water heater drain valve to vacate water
from the tank. The water will automatically drain into the
shower sump pump and then will be sent overboard. Make
sure the water heater breaker is turned off before any
winterization is started to prevent the element from being
burned out.
B. If the system is constantly being used in warmer climates
it is a good idea to periodically drain the hot water valve
for 30 seconds or so to eliminate any scale that has built up
inside the hot water heater. Turn the breaker off just as a
precaution.
C. The hot water heater and heat exchanger parts are made
of aluminum. If engine flushing is required by the
manufacturer be sure to disconnect the heat exchanger from
the system temporarily. The caustic chemicals will damage
the hot water heater aluminum parts. Re-plumb the heat
exchanger after engine flushing.
D. Test the T& P valve periodically to make sure it works
properly. Its purpose is to let off excess water vapor (steam)
if the thermostat should stick and a critical temperature
situation develops within the tank. With the water heater
at operating temperature (use gloves) pull on the valve
trigger top and raise the trigger to 90 degrees to test it. The
water will vacate to the shower sump pump.
