The following steps should be
performed by an authorized
Hydromatic service center
or distributor.
Note: Use extreme caution
around electrical devices.
Electrical shock may occur.
1. Before removing pump from
the sump, check to be sure the
problem is not a blown fuse,
tripped circuit breaker or a
power cord not completely
inserted into the receptacle.
2. If the unit is being operated by
an optional control switch,
unplug the pump from the
piggyback receptacle and plug
the pump directly into the
power source. If the pump
starts each time it is plugged
directly into the receptacle and
does not start each time when
plugged into the piggyback
switch with the float raised or
diaphragm pressed up to a start
position, replace the complete
switch assembly and retest
with new assembly.
3. If pump fails the above two
steps, remove pump and
switch from power source to
avoid electrical shock. Then
pull the pump from the sump
by the handle. Sandblast, if
possible, any dirt or trash
from the outside of the pump
before dismantling.
4. If the above tests have not
resolved the problem, it may
be in the electrical components
of the pump. Starting with the
power cord, inspect for cuts or
nicks in the insulation. If the
cord is damaged – replace it!
5. Using the ohmmeter, check
the resistance of the motor
windings by connecting one
lead clip to each electrical
“flat” prong on the power cord
pump mud, cement, tar,
abrasives or chemicals.
If...
pump has been used for
pumping of hot water
(above 120° F).
If...
pump has been dismantled
by other than authorized
Hydromatic service center
or distributor.
12.To ensure that the pump is
properly installed, fill basin
with enough water to activate
pump. Allow the pump to go
through several on-off cycles
to assure satisfactory operation.
13.Use pump partially or
completely submerged for
pumping waterlike liquids
(temperature to 140°
F).
The SKV50 will pump solid
materials up to 2" (spherical)
in diameter.
Caution: Do not pump
flammable liquids, strong
chemicals or salt water.
Your pump warranty is void...
If...
power cord has been cut.
If...
pump has been used to
Read the following instructions
carefully before replacing any
parts. Reasonable care and safe
methods should be practiced.
Check local codes and
