PLUMBING
CAUTION
!
Never allow the pump to run for long periods of time
without water in the supply tank, as pump damage or
blown fuses may result.
Operation
1. Fill or partially fill the fresh water supply tank.
2. Open the kitchen and bathroom faucets.
3. Turn the water pump switch on, and allow the water to
fill the water line and the hot water heater. The switch
to this pump may be located in the exterior water
compartment, in the kitchen, or in the bathroom.
4. Close each faucet after it delivers a steady stream of
water (close the cold water first). Leave the hot water
faucets on until they also deliver a steady stream of
water. This will ensure that the water heater is filled
with water.
5. The water pump should stop running once all faucets
are closed.
6. The pump is now ready for automatic operation. The
pump will run when a faucet is opened and stop when
a faucet is closed and the correct pressure has been
reached.
Water Pump Operation and Basic Troubleshooting
The water pump is self-priming and totally automatic, operating on demand whenever water is required. 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.
Water Pumps and Controllers
When the water pump switch is turned on, the water
pump builds pressure in the system and will shut off
as soon as the system is correctly pressurized. When a
faucet is opened, the pump will turn on and operate as
necessary to maintain the preset pressure in the system.
Water pump operation is not necessary while the coach is
connected to city water, since the potable water is already
pressurized.
When using water at a low flow rate (GPM), the pump may
pressurize the system and short cycle, meaning the pump
shuts on and off quickly. In many cases, the pump will
stop short cycling if the flow rate of the water is increased.
Care and Maintenance
All of the water should be drained from the fresh water
system when the unit is not in use for more than one
week.
Troubleshooting
If water doesn’t flow when a faucet is turned on
while using the demand system, use the following
troubleshooting tips.
If the pump is running, but there is no water:
•
Fill the tank.
•
Clear the water line to the pump or the pump inlet
filter.
•
Rotate the city water / tank fill valve to the correct
position.
If the pump isn’t running:
•
Check the pump switch.
•
Check the 12 Volt fuses.
•
Check the electrical connections.
•
Check the battery.
Water Pump Operation via SilverLeaf
This article provides a basic overview of the water pump operation via the SilverLeaf system. The water pump may be
operated from one or multiple locations, depending on the coach model, year, and floorplan.
The SilverLeaf TM-102 module receives inputs from
the water pump button or switch on the SilverLeaf
touchscreen panel, the remote monitor panel in the
water compartment, or the KIB V-BUS switch panel(s) (if
equipped). By activating the water pump button or switch,
the TM-102 energizes the water pump relay in the KIB
circuit board, which grounds the circuit. Once the pump
pressure switch makes contact, the pump will supply
water pressure to the fresh water system. The pump will
shut off once the pump pressure switch is satisfied.
