3.2. Operating the appliance

a) It is recommended to use a flexible hose for potable water or a PEX tube
instread of a rigid pipe to connect to the pump.
b) Do not use metal couplings for the connections. Use plastic couplings
whenever possible.
c) Only a qualified technician may adjust the bypass.
d) The pump can be installed in any orientation. If installed in vertical orientation,
the pump head must be at the bottom to avoid ingress of water into the motor
in the event of a failure.
e) The suction hose must be reinforced with a minimum I.D. of 3/8" (10 mm). The
discharge hose I.D. shall be 3/8" (10 mm).
f) Plumb the system using high-pressure rated (up to 2 x pump power rating),
braid-reinforced, flexible piping to minimise vibration and noise.
g) Do not apply an inlet pressure above 30 psi (2.07 bar) at the suction side. Avoid
any inlet overpressure whenever possible.
h) Avoid all kinks and couplings which would restrict the water flow too much.
i) Connect the filter on the inlet/suction side.
j) Secure all connections against leaks.
k) Use band clips to attach both ends of the hose and avoid air leaks into the
water line.
l) If a water stop valve is installed in the riser, its opening pressure shall not
exceed 2 psi.
m) If using a piping sealant or a sealing tape for water piping, do not tighten the
connections sealed with these products too much or the products can be
sucked into the pump.
n) Connect the water pump to a separate power line from the power source.
Connect the red (positive) lead to the positive (+) terminal post of the battery.
Connect the black (negative) lead to the negative (-) terminal post of the
battery.
o) Do not connect other electrical loads to the pump's power line.
p) Install a service switch in an accessible location for easy operation of the
pump's electrical power source. Always stop the pump if it is not going to be
used for a long time or when the tank is empty.
q) Always install a fuse with a suitable rating. If there is a short circuit, an
unsuitable rating of the fuse increases the risk of pump failure and may
potentially result in injury and/or a risk of fire.
