• Running the pump with the
discharge completely closed.
• Pumping chemicals or
corrosive liquids.
19.Never work on the pump or
system without relieving the
internal pressure.
20.Do not pump water above 120°
Fahrenheit.
21.Never exceed the pressure
rating of any system component.
Read this guide completely
before installation.
Hydromatic recommends an
experienced serviceman to install
new systems.
Please read this entire guide before
installing your Hydromatic
submersible pump.
CAUTION: Do not run unit dry.
Unit can be severely damaged if
run dry.
15.Do not pump gasoline,
chemicals, corrosives, or
flammable liquids; they could
ignite, explode, or damage the
pump, causing injury and
voiding the warranty.
16.Do not run this pump with the
discharge completely closed.
This will create superheated
water, which could damage the
seal and shorten the life of the
motor. This superheated water
could also cause severe burns.
Always use a pressure relief
valve, set below the rating of
the system.
17.Pump is capable of building
pressures in excess of 100 psi.
Always use a pressure relief
valve.
18.The following may cause
severe damage to the pump
and void warranty. It could
also result in personal injury:
• Running the pump dry.
• Failure to protect the pump from
below freezing temperatures.
6. A clamp, a weld, or both if
necessary, is secured to the
equipment grounding lead, the
equipment grounding terminal,
or the grounding conductor
on the pump housing. The
equipment-grounding lead, if
one is provided, is the conductor
that has an outer surface
of insulation that is green
with or without one or more
yellow stripes.
7. The voltage and phase of the
power supply must match the
voltage and phase of the pump.
8. Do not use an extension cord;
splices must be made with an
approved splice kit and should
be checked for integrity before
submerging in water; above
ground joints must be made in
an approved junction box.
9. Do not work on this pump or
switch while the power is on.
10.Never operate a pump with a
frayed or brittle power cord,
and always protect it from
sharp objects, hot surfaces, oil
and chemicals. Avoid kinking
the cord.
11.Never service a motor or
power cord with wet hands or
while standing in or near water
or damp ground.
12.Do not use this pump in or near
a swimming pool, pond, lake
or river.
13.Motors are equipped with
automatic resetting thermal
protectors. The motor may
restart unexpectedly causing
the leads to energize or pump
to turn.
14.Check for nicks in the wire
and pump insulation by using
an ohmmeter and checking
resistance to ground before
installing the pump and after
installing pump. If in doubt on
the proper procedure, check
with a qualified electrician.
