NOTE: When installing the pump, some water from factory testing may spill
out.
INSTALLATION
Before installing the pump, check that all of the following components and
accessories are included in the box:
Water pump
Strainer
2 X ½” hose barb adapters
2 X ½” threaded adapters
12 volt battery alligator clips (w/ 15A fuse)

ENGLISH
Make sure to install the pump indoors in a dry area.
Mount the pump horizontally or vertically. If mounting vertically, make
sure to mount with pump head down to avoid damaging the motor in
case of leakage.
Secure the feet with 4 screws.

Insert the included hose barb or threaded quick connect adapters in the
inlet and outlet pump ports , and slide clips to lock port connec-
tions.
If using the included strainer, insert into the inlet port and slide clip to
lock port connection.
Use ½” (13mm) I.D. exible hose (preferably braided or reinforced) to
connect to the inlet and outlet of the pump. Use hose clamps to secure
the hose to the hose barb connectors (if hose barb adapters are being
used).

Connect the positive red wire to the positive (+) terminal of your battery
and the negative black wire to the negative (-) terminal of your battery.
A 15 amp switch is recommended and should be installed on the
positive red wire.
Use a 15 amp fuse protection on the positive red wire to protect the
pump.

WIRING
The pump should be wired on its own dedicated circuit protected by the
recommended fuse indicated in this Operating Manual.
It is highly recommended to install an approved marine duty (ignition
protected) switch rated at 15 amps or above to control power to the
pump.
Make sure to shut o power to the pump when not being used for ex-
tended periods of time.
Proper wire sizing is required for good pump operation. If the wire is
too small, low voltage will aect the pump performance and can create
a re hazard.
The total current draw on the circuit must not exceed 15 amps. If the
pump is used in conjunction with other components, overload current
protection (fuse or circuit breaker) and wire size must be for the total
amp requirements of all devices on the circuit.

ENGLISH
The inlet and outlet hose must be a minimum ½” (13mm) I.D. exible
hose to both ports. Using a hose with a smaller diameter can cause high
backpressure, cycling, low ow and noise.
Installation of a strainer is required to prevent debris from entering
the pump. Pump failure due to foreign debris is not covered by the
warranty.
Mount the pump within 5 feet of the tank (or any other water source) for
best performance and pump life. The greater the distance between the
pump and the water source, the greater the strain on the pump.
Plumb the system using high pressure, braided, exible hose to mini-
mize vibration and noise. The pump’s ports and strainer should not
be connected to plastic or rigid pipes. The pump’s normal oscillation
motion will transmit through rigid plumbing, causing noise and possibly
loosening or cracking components.
To prevent rapid cycling (pulsating ow) caused by excessive back pres-
sure, check for the following restrictive elements within your plumbing
system:
Water lters / puriers NOT on separate feed lines
Flow restrictors in faucets and showerheads
I.D. hoses and pipes smaller than ½” (13mm) throughout the plumbing
system

OPERATION
NOTE: This pump is designed for intermittent duty only. Continuous
duty usage will shorten the life of the pump and is not covered under
the warranty.
Make sure the pump is installed properly according to the installation
instructions above (wait before powering the pump).
Make sure the battery being used to power the pump is fully charged.
Open the water source (showerhead, faucets, etc.) connected to the pump.
Switch ON power to the pump. Water will begin to ow and ll the
water lines connected to a water heater, toilet, shower, etc. The goal
is to remove the air from the plumbing system and ll it with water.
Once the lines are completely lled with water, shut o all water x-
tures (showerhead, faucets, etc.).
When all water xtures are shut o, the pump will stop automatically
(if the pump fails to stop, switch OFF power to the pump and refer to
the Troubleshooting section of this Operating Manual).
The pressurized plumbing system is now ready for use. Open the water
xture needed and the pump will automatically start pumping water to it.

ENGLISH
Potable water systems require periodic maintenance to keep components
working and to deliver a consistent ow of fresh water. Depending on use
and the environment the system is subjected to, sanitizing is recommend-
ed prior to storage and before using the water system after a period of
storage.
If water is left to freeze in the water system, serious damage to the plumb-
ing and the pump may occur. Failures of this type will void the warranty. The
best guarantee against damage is to completely drain the water system.
SANITIZING
WINTERIZING
NOTE: Check your RV, watercraft or other equipment manufacturer’s
manual for specic sanitizing instructions.
NOTE: When used per the manufacturer’s recommendations, non-
toxic antifreeze for potable water is safe for use with the Onsen 3.0
Pump. Refer to the manufacturer for specic winterizing and drainage
instructions.
DO NOT USE AUTOMOTIVE ANTIFREEZE TO WINTER-
IZE POTABLE WATER SYSTEMS. THESE SOLUTIONS ARE
HIGHLY TOXIC AND MAY CAUSE SERIOUS INJURY OR
DEATH IF INGESTED.
WARNING

[e-mail]
Drain the water tank. If the tank doesn’t have a drain valve, open all
water xtures and allow the pump to operate until the tank is empty.
Do not operate the pump for longer than 15 minutes continuously.
Switch OFF power to the pump and make sure that all water in the
drain lines is evacuated.
Remove the quick connect inlet and outlet ttings from the pump
and switch ON power to the pump to remove any remaining water
from the pump head. Switch OFF power to the pump and leave the
ttings disconnected from the pump until the system is ready to be
used again.
All xtures must be left open to safeguard against any damage to the
plumbing.
