Satellite Slide Tank - Manual (Page 22)

Additionally, the gas engine will also
provide a charge to the battery when the
sewage compartment is being filled
(during which time the water pump is not
in use). This will further add to the battery
charge, however, large demands on the
water pump can still leave the battery
depleted.

MAINTENANCE
When using the water pump frequently
throughout the day it is necessary to
recharge the battery using a battery
charger. Usually, this can be done at the
end of the day so as to avoid interfering
with normal operation.
As an alternative, frequent high amperage
demand on the water pump can be met by
wiring the unit into the electrical system of
your truck. This is a relatively
straightforward process requiring the
following materials:
• Number 12 automotive wiring
• A 15 amp fuse assembly
• A toggle switch assembly
Install the new circuit for the water pump by
splicing into an unused auxiliary circuit
under the dashboard. Most vehicles have
some unused auxiliary circuits available for
various vehicle options. Use a test meter to
verify which line in the circuit has an
amperage draw and which is the ground
wire.
Route the wiring from under the dashboard
to the back of the truck where the toggle
switch will be located. Mount the toggle
switch in a convenient location such as on
the weldment stand that supports the slide-
in engine and pump assembly.
Splice the fuse assembly into the wiring
run so that it will be in an accessible
location. Then, wire the run to the newly
installed toggle switch. Finally, detach the
water pump wiring from the existing switch
and attach it to the new switch. The water
pump will now start up when the truck
ignition key is in the accessory position
and the toggle switch is in the on position.
As an added note to pump operation,
during cold weather (below 32°), drain the
liquid from your pressure water pump to
prevent freezing and damage to the pump
housing. In addition, drain all water lines
and filters to protect them from freeze-up.
WARNING : DO NOT use a tight
fitting on the fresh water compartment fill
port. This port is designed to be self venting
and performs this function with the use of
your fill line of a smaller diameter. Failure to
allow the vent to function can result in
damage to the tank and serious personal
injury.
`
NOTICE : DO NOT allow water to freeze
inside the pump. Do not attempt to start the
pump if water has frozen inside it. Freezing
water can damage your pump. Take the
truck into a warm area and allow the pump
the thaw out.
Cold Weather Operation
Use the following guidelines when
operating your vacuum tank in
temperatures below 32°F.
Extremely cold weather can result in
formation of ice inside the vacuum pump,
due to residual moisture. If the pump
freezes up due to ice, take the truck into a
warm area and allow the pump to thaw.
DO NOT use a blowtorch or other similar
device to attempt to thaw a frozen vacuum
pump.
Frigid temperatures could also cause the
dump or load valves to freeze shut. Hot
water poured over a frozen valve should
loosen the ice. DO NOT use a blowtorch or
similar device to thaw a frozen valve. This
method could damage the valve.
