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 instructions
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 S4S/SB4S 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 4 wire with
the 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 guarantee
is void.
