INSTALLATION WIRING
STE 1
Remove shipping plugs from pump ports. Some water
from factory testing may spill out.
STE 2
Connect fittings supplied with the pump to the RV’s
plumbing. Use 1/2’ I.D. Flexible hose (preferably braided
or reinforced) to reduce vibration through the plumbing
system as shown on Fig. 1. Use hose clamps on the
slip-on barb hose connectors.
STE 3
Slide rubber mounts fully into 4 mounting tracks.
STE 4
Mount pump vertically, with pump head down or
horizontally in an accessible location. If mounting
vertically, motor up, attach motor mounts first then pump
head mounts, while supporting weight of pump.
STE 5
Install inlet A and discharge B port connectors. Firmly
push slide clips C forward to lock port connectors in
place.
STE 6
Install a Flojet strainer in an accessible location (for
inspection and cleaning) between the tank and pump inlet.
This strainer or equivalent is required for pump warranty
to be valid.
STE 1
Use 14 gauge stranded wire to 20’, 12 gauge to 50’,
from power source.
STE 2
Use a 10-15 amp rated on-off switch on the (+) positive
(red) motor lead.
STE 3
Install a 10 amp fuse protection on the positive lead.
FIG. 1
Note: To help reduce noise and vibration of the pump
through the system use flexible lines on the inlet and
outlet of the pump as shown above. Be sure to use
lines rated to not collapse under pump vacuum.

Winterizing Sanitizing
SYSTEM CARE AND MAINTENANCE
Allowing water to freeze in the system may result in
damage to the pump and plumbing system.
Non-Toxic antifreeze for potable water may be used with
Flojet pumps. Follow manufacturers recommendations.
Refer to coach or equipment manufacturers instructions
for their specific winterizing and drainage procedures.
Do not use automotive antifreeze to winterize potable
water systems. These solutions are highly toxic and may
cause serious injury or death if ingested.
1. Drain the water tank. Open tank drain valve and
plumbing drain valves if applicable. You may use the
pump to drain the tank by opening all the faucets in the
system. Allow the pump to operate until the tank is
empty. Do not operate the pump more than 15 minutes
continuously.
2. Open all faucets and flush the toilet to purge all the
water from the pump and the plumbing system. Run
the pump until no water is coming through the faucets.
Turn power to the pump off. Be sure that all the water
from the drain lines are drained.
3. Remove quick connect inlet and outlet fittings from the
pump and turn the pump on to pump out remaining
water from the pump head. Be sure to have a catch pan
or a rag under the pump to prevent water from spilling
on to the RV. Turn the pump off once the plumbing is
empty. Leave the fittings disconnected from the pump
until the system is ready to be used again. Make a note
on your tank filler that the plumbing is not connected.
4. Be sure that all faucets are left open to protect against
damage to the plumbing.
Portable water systems require periodic maintenance to
deliver a consistent flow of fresh water. Depending on
use and the environment the system is subject to,
sanitizing is recommended prior to storing and before
using the water system after a period of storage.
Systems with new components, or ones that have been
subjected to contamination, should also be disinfected
as follows:
NOTE: The sanitizing procedure is in conformance with
the approved procedures of RVIA ANSI A119.2 and the
US Public Health Service.
1. Use of the following methods to determine the amount
of common household bleach needed to sanitize the
tank.
1. A) Multiply “gallons of tank capacity” by 0.13; the
result is the ounces of bleach needed to sanitize
the tank.
1. B) Multiply “Liters of tank capacity” by 1.0; the result
is the milliliters of bleach needed to sanitize the
tank.
2. Mix into solution the proper amount of bleach within a
container of water
3. Pour the solution (water/bleach) into the tank and fill
the tank with potable water.
4. Open ALL faucets (hot and cold) allowing the water to
run until the distinct odor of chlorine is detected.
5. The standard solution must have four (4) hours of
contact time to disinfect completely. Doubling the
solution concentration allows for contact time of one
(1) hour.
6. When the contact time is completed, drain the tank.
Refill with potable water and purge the plumbing of all
sanitizing solution.
