CAUTION
DO NOT release the fresh water hose during the retraction process. Spring tension on the hose reel
can cause the hose to retract very quickly, and can cause physical harm or injury to you and damage
to your coach.
Fill Valve Operation
The rotating “Fill Valve” located in the center of the water compartment is used to pressurize the
fresh water system in your unit, as well as to fill the fresh water demand tank. When the unit is
connected to city water, the “Fill Valve” is used to pressurize the fresh water plumbing in your
unit, or fill the fresh water tank, or both. The panel is clearly labeled; simply rotate the “Fill
Valve” to the appropriate position to perform the desired function. You can monitor the fresh
water tank via the small “Multiplex” display unit located in the basement water compartment.
Domestic Hot Water
The hot water in your unit is heated by the Oasis hydronic heating system. Turning the 110
heating element on will usually provide sufficient hot water for most household chores. To
operate an appliance that uses water, or to assure plenty of hot water for showering, turn on the
Hydro-Hot boiler in the front overhead cabinet. Both heat sources can be used at the same time.
Water Filtration System
Your Essex was manufactured with a fresh water filtration system. This system uses extruded
carbon filter cartridges to remove sediment and certain impurities from the incoming water
supply. The filter assembly is located in the basement water compartment.
To replace the filter cartridge, turn off the water supply to the RV (at the city water connection).
Unscrew the filter canister by rotating it clockwise. Replacement filter cartridges are available
through your Authorized Newmar Dealer; have them order part number 03738.
Insert the new filter cartridge, positioning it so the opening in the bottom of the filter seats on the
molded ring at the bottom of the canister. Reattach the canister to the filter housing by rotating
the canister in a counter clockwise direction. When replacing the filter, make certain the rubber
“O-Ring” seal is properly positioned in its groove in the cartridge housing. An improperly seated
or missing seal will cause leakage around the perimeter of the filter housing. Use caution not to
over tighten the canister when attaching it back to the housing.
IMPORTANT
DO NOT ALLOW WATER TO FREEZE IN THE WATER FILTER CANISTER. Freezing will crack and
permanently damage the filter housing and associated plumbing. ALWAYS REMOVE THE FILTER
CARTRIDGE PRIOR TO WINTERIZATION.
