Thank you for purchasing your
Hydromatic®pump. To help ensure
years of trouble-free operation,
please read the following manual
carefully.
Before Operation:
Read the following instruc-
tions carefully. Reasonable care
and safe methods should be
practiced. Check local codes and
requirements before installation.
Attention:
This manual contains important
information for the safe use of
this product. Read this manual
completely before using this
product and refer to it often
for continued safe product use.
DO NOT THROW AWAY OR
LOSE THIS MANUAL. Keep
it in a safe place so that you may
refer to it often.
Unpacking Pump:
Remove pump from carton.
When unpacking unit, check for
concealed damage. Claims for
damage must be made at the
receiving end through the delivery
carrier. Damage cannot be
processed from the factory.
WARNING: Before handling
these pumps and controls,
always disconnect the power
first. Do not smoke or use
sparkable electrical devices or
flames in a septic (gaseous) or
possible septic sump.
Pumps Not Operating or
in Storage:
Pumps with carbon ceramic seals
must have impellers manually
rotated (6 revolutions) after
setting non-operational for 3
months or longer and prior to
electrical start-up.
Pump:
The S3SD/S4SD series
submersible pumps are supplied
for 1 and 3 phase and for 200,
230, 460 or 575 volts. Pump is
supplied with 15 feet of power
cord. Longer cable lengths can be
furnished but must be specified
at time of order. Power cable
is supplied with a green wire
for ground. Be sure green wire
is connected to a ground lug in
the control panel and the control
panel must be connected to a
ground rod or ground wire from
supply service.
NOTE: All single phase pumps
require properly sized start
capacitor, start relay and run
capacitor in the panel.
Sump Level Control:
Sump level is controlled by
Hydromatic 3900 mercury
switch level controls. The 3900
level controls is a metal case
mercury switch sealed in a solid
polyurethane float. The float
is held in position by a weight
attached to the power cord above
the float. The cord supports the
float and is adjusted for height
from the surface.
Typical duplex systems use three
floats; the lowest float turns the
pumps off, the next higher float
starts the lead pump, the next
higher float (override) starts the
lag pump. The pumps alternate
on successive cycles.
General
Information
Two pumps operate together only
if sump level rises to the third or
override float. The override float
also brings on the second pump in
case of failure of the first pump.
Extra floats with appropriate
controls can be supplied for alarm
functions. Triplex systems use
four floats. The fourth highest
float brings on the second lag
pump. Three pumps operate
together only if sump level rises to
the fourth float (second override).
This float also brings on the third
pump in case of failure of either or
both of the first two pumps.
Alarm Controls:
The alarm float is usually set
above the override level so the
alarm will signal only if the
override level is exceeded.
However, some engineers prefer
to have the alarm float set below
the override level as it is possible
for one pump to fail and the other
pump to operate on the override
level with the sump level never
reaching the alarm level. This is
particularly true in cases of low
inflow capacity.
Electrical Control Panel:
It is recommended that the
Hydromatic control panel be used
with all pumps as proper start
components and pump protection
are furnished.
NOTE: All single phase pumps
require properly sized start
capacitor, start relay, and run
capacitor in the control panel.
IMPORTANT: If Hydromatic
control panel is not used and the
motor fails because of improper
components, the motor guaran-
tee is void.
