Fresh Water Tank Low
Point Drain
The fresh water tank low point drain is used to empty the fresh water tank. Open the low point drain valve to drain the fresh water tank, and close
the low point drain valve when filling the fresh water tank or storing fresh water in the tank. This low point drain is located near the fresh water
tank and may be difficult to see from the outside. It is often located just behind the lip of the white drain pan when the fresh water holding tank is
located in the main water compartment. When the fresh water holding tank is located outside of the main water compartment, the fresh water tank
low point drain is typically near it.
9 Fresh Water Tap
The fresh water tap provides a connection for an additional hose hookup for access to potable water. Use the water tap to water plants, fill a pet's
water bowl, or wash the coach while still having access to the city water connection. If not connected to a pressurized water source, the water
pump must be turned on to use the water tap.
10
Hot and Cold Low Point
Drains
Typically the coach has one hot water low point drain and one cold water low point drain, which are used to empty the water lines. Open the valves
to relieve water pressure and drain the water lines. Close the valves for normal operation of the pressurized water system.
11 LED Light Strip Some lights are operated automatically via a plunger switch that activates the lights when the compartment door is opened.
12 Oasis Heat Exchanger
The Oasis heat exchanger is used to heat the water compartment in order to keep the bay temperature above freezing. This exchanger may be
located behind a panel or cover and may not be visible from the outside.
Note: Power must be supplied to the Oasis system and the system must be turned on via the control panel or SilverLeaf coach management
system in order for heat to be provided to the water compartment. Once both conditions are met, the thermistor will turn the heater on once the
compartment falls to approximately 40 degrees.
13
Sani-Con Discharge
Hose Shutoff Valve
The Sani-Con small hose shutoff valve is used to shut off the waste flow to the macerator drain hose. This valve can be shut off when using a 4"
gravity drain hose and/or to prevent pressure and waste in the small macerator hose when not in use or in the event that it develops a leak. This
valve must be open prior to turning on the macerator when emptying the holding tanks via the macerator drain hose. Open the valve all the way by
pulling on the T-handle to allow waste to flow through the small macerator hose. Close the valve by pushing on the T-handle.
14
Sani-Con Macerator
Discharge Hose
The Sani-Con macerator discharge hose is used to direct the effluent to a sanitary dump station.
15
Sani-Con Waste
Disposal Switch
The Sani-Con waste disposal switch is used to turn the coach's macerator on and off. The switch should not be turned on until the small macerator
discharge hose is connected to a proper dump station, the small hose shutoff valve is opened, and the black (sewage) or gray (waste) holding tank
dump valve is opened.
16 Sewage (Black) Tank
The black tank is generally for sewage waste from the stool. It is typically located between the frame rails in the water compartment. This tank may
be located behind a panel or cover and may not be visible from the outside.
17
Sewage (Black) Tank
Dump Gate Valve with
T-Handle
In conjunction with the sewage holding tank, the sewage tank dump valve provides adequate and safe storage and/or controls the disposal of
waste materials. Open the black tank gate valve all the way by pulling on the T-handle. The tank will start to drain to the macerator or drain outlet
as soon as the T-handle is pulled. The 4" drain line or macerator hose should be used to direct waste to the dump station for proper disposal.
18
Sewage (Black) Tank
Rinse Connection
When draining your sewer tank, attach a water hose to the sewage tank rinse connection. After the tank is drained, leave the gate valve open, and
open the water valve to the attached hose, allowing water to spray inside the sewage tank for several minutes to flush and rinse the tank.
19
Sewage (Black) Tank
Rinse Low Point Drain
On coaches equipped with sewage tank rinse low point drain(s), turn the tank rinse drain valve to the "open" position to remove pressure and drain
the tank rinse line. When finished using the tank rinse, it is recommended to turn off the water supply to the tank rinse connection. Open the valve,
and drain off the pressure in the line before disconnecting the water hose.
20
Sewer Hose Hatch
(Access Port)
The sewer hose hatch is a removable cover that allows the sewer hose or the small macerator hose to exit through the compartment floor in order
to connect to a proper dump station. This allows the compartment baggage door to close without hindrance from the hose. The cover may be
threaded or clipped.
Note: When routing the sewer or macerator hose through the hatch, do not place on or near the Oasis, generator, or engine exhaust pipes.
Otherwise, damage may occur.
21
SilverLeaf HMS404
Tank Monitor
Touchscreen Display
The SilverLeaf HMS404 tank monitor display allows the user to operate the water pump or auto fill function, as well as many other features. For
more information, refer to the operation and settings outlined in the SilverLeaf Touchscreen Guide specific for the coach model and year. This
guide can be located in Newgle.
22
Waste (Gray) Water
Tank
The gray water holding tank is typically located in the underbelly of the coach, sometimes on top of the fresh water tank. It is primarily used for the
drainage from the kitchen and bath sinks, shower, and the washing machine (if equipped).This tank may be located behind a panel or cover and
may not be visible from the outside.
23
Waste (Gray) Water
Tank Dump Gate Valve
with T-Handle
In conjunction with the gray (waste) water holding tank, the gray (waste) tank dump valve provides adequate and safe storage and/or controls the
disposal of waste water. Open the gray (waste) gate valve all the way by pulling on the T-handle. The tank will start to drain to the macerator or
drain outlet as soon as the T-handle is pulled. The 4" drain line or macerator hose should be used to direct waste to the dump station for proper
disposal. Newmar recommends dumping and flushing the gray (waste) water holding tank after the black (sewage) holding tank.
24
Waste (Gray) Water
Tank Rinse Low Point
Drain
On coaches equipped with gray (waste) tank rinse low point drain(s), turning the tank rinse drain valve to the "open" position will remove pressure
and drain the tank rinse line. When finished using the tank rinse, it is recommended to turn off the water supply to the tank rinse connection. Open
the valve, and drain off the pressure in the line before disconnecting the water hose.
Note: Not all coaches are equipped with gray tank rinse.
25
Waste (Gray) Water
Tank Rinse Connection
When draining your gray (waste) tank, attach a water hose to the gray (waste) tank rinse connection. After the tank is drained, leave the gate valve
open, and open the water valve to the attached hose, allowing water to spray inside the sewage tank for several minutes to flush and rinse the
tank.
Note: Not all coaches are equipped with gray tank rinse.
26 Water Pump with Filter
When not connected to city water, the coach's water pump is used to pump and pressurize water from the fresh tank for distribution through the
hot and cold water lines. When activated, the water pump will automatically turn on and off to maintain proper water pressure in the coach.
27
Whole House Water
Filter
The whole house water filter system uses a replaceable extruded carbon filter cartridge to remove sediment and certain impurities from the
incoming water supply. This filters the fresh water as it is brought in to the coach from the city water connection through the hose or hose reel.
28
Winterizing and
Antifreeze Inlet Valves
(A and B)
The winterizing valves are only used during the coach winterization process. To determine proper valve positioning throughout the process,
follow the posted instructions in the coach water compartment for the A and B valves. These valves may be located outside of the main water
compartment on some coaches.
