CALIFORNIA PROPOSITION 65 WARNING:
This product and related accessories contain
chemicals known to the State of California to cause cancer, birth
defects or other reproductive harm.
Submersible grinder pumps are not approved for use in
swimming pools, recreational water installations, decorative
fountains or any installation where human contact with the
pumped uid is common. This specialized pump is designed
to incorporate a grinding mechanism to remove wastewater
particulate and pump the resulting slurry.
On single and three-phase pumps, the motor protection must
be provided by the installer. All three-phase pumps must be
installed with magnetic starters having three-leg overload
protection in accordance with the national electric code. For
duplex installations, both pump motors must have separate
overload protection. Seal leak detectors must be connected to
the proper control circuitry.
Examine all lifting devices, rope or chain, for damage before
and after each lift. Do not use any lifting devices that are
not rated for and designed to lift the weights involved with
these
pumps.
Keep clear of suction and discharge openings and do not insert
ngers in the pump with the power connected. Make sure
lifting devices are securely fastened each time before lifting
pump and do not lift pump by the power cord. Do not exceed
manufacturer’s recommendation for maximum performance, as
this could cause the motor to overheat. Do not pump without
safety devices in
place.
sharp.
Control Panels and Controls: All Hydromatic
®
control panels used
on these grinders are UL listed and CSA certied. Intrinsically
safe type oat controls are recommended for all applications.
An intrinsically safe control panel relay will limit the current and
voltage to the level controls. Hydromatic control panels can be
supplied with this type circuitry.
The oat level controls maintain the basin sewage water level
by controlling pump turn-on and turn-o level. The lower
turn-o control should be set so that the pump stops at
approximately the top of the pump. The upper turn-on control
should be set above the lower turn-o control. The exact height
between the two controls is determined by the number of pump
starts desired and the depth of the basin. A maximum of 10
starts per hour should not be exceeded. The override control is
set at a specied height above the upper turn-on control. The
alarm control is set about 6" to 12" above the override control.
No control should be set above the inlet invert.
Pump: The HV200 pumps are equipped with 200 and 230
volt single-phase and 200, 230, 460 and 575 volt three-phase
with seal leak detector. HV200 Series pumps are available in
standard or high head ows. This pump is intended to grind and
pump all normal sewage.
Caution: Pump is only to be disassembled at Hydromatic
factory or an authorized Hydromatic service facility.
Single-phase motors are capacitor start, capacitor run and
the relays are mounted in the electrical control box. All singlephase motors must have a special electrical control box
by
Hydromatic. Installing single-phase motors with controls
other than Hydromatic voids warranty.
Pump has two oil-lled chambers, the motor and ball bearings,
and the seal chamber. The lower seal above the pump impeller
acts as a buer for the upper seal that holds oil in the motor
chamber. The lower seal detection will alarm if water enters the
chamber.
seal
Cords: Pump models with a seal leak detector use a ve-
conductor cord. The three power conductors are black, white
and red. The orange conductor connects to the seal leak probe
and the green conductor connects to the ground screw inside
the cord cap.
Single-phase pumps use the black and white as main winding
leads and the red for the start winding.
Cutters: The HV200 grinder is equipped with an axial style
cutter, a stationary plate and rotating cutter. To ensure proper
operation of the cutting mechanism, the gap between the
stationary plate and rotating cutter must be no more than .008".
If the pump is ever disassembled, the gap must be checked
before the pump can return to service. To check the gap, use
a .008" feeler gauge. If the .008" feeler gauge does not t
between the surface of the stationary cutter and rotating cutter
and the motor shaft turns freely, the gap is set properly. If the
.008" feeler gauge ts between the surfaces, shims must be
removed to close the
gap.
Three-Phase Control Box: Hydromatic three-phase control
equipment can be used for simplex or duplex operation. The
overload heaters are in accordance with full load amp
ratings.
If any amp readings are higher than listed, it indicates voltage
may be higher or lower than normal, or that the pump may
clogged.
be
Resistance of Winding: Every motor winding has a xed
resistance and windings must check close to the specication
values. This winding resistance also indicates if the motor is
connected for the voltage being used. Use ohmmeter to test
and read output directly in ohms.

TROUBLESHOOTING
CONDITION PROBABLE CAUSE
Pump runs but does not pump liquid from basin.
Red light comes on at control box.
Overload trips and high water level alarms.
Yellow run light stays on continuously.
Circuit breaker trips.
Pump is noisy and pump rate is low.
Grease and solids have accumulated around pump
and will not pump out of the basin
Pump impeller may be air locked; this occasionally occurs in a new
installation. Start and stop pump several times to purge air.
Run additional water into basin so that the pump will be submerged
deeper to clear air.
If air does not clear, it may be necessary to lift pump out of sealing
elbow and start motor to allow pump to pump for a few seconds. If
discharge is piped in with union, slightly break union and start pump
to clear air.
If pump has been installed for some time and does not pump, it may
be clogged at grinder inlet.
Discharge gate valve may be closed.
Discharge check valve may be clogged or have a broken clapper.
Discharge head may be too high. Check elevation.
This indicates some water has leaked past the lower seal and has
entered the seal chamber and made contact with the electrode
probe. Pump must be removed from basin immediately for
replacement of lower seal.
Push in red reset button to reset overload. If overload trips again after
short run, remove pump and check for damage.
Check grinder for clogged material as this can cause an overload
condition on the motor
A faulty component in the control box could exist.
Indicates H-O-A switch may be in the Hand position.
Level control switch may have failed causing pump to continue to
operate when water is below lower
Grinder assembly may be partially clogged causing pump to operate
at very reduced capacity.
Check valve may be clogged causing low pump ow. Gate valve may
be in O position.
Pump may be air locked.
Reset breaker by pushing clear down on the handle, then put back
to the On position. If breaker trips again in a few seconds, that
indicates excessive load probably caused by a short in the motor or
control box.
If condition happens after an electrical storm, motor or control box
may be damaged by lightning.
A resistance reading of the motor with the lead wires disconnected
from the control box can determine if the trouble is in the motor or
control box.
Grinder assembly may be partially clogged with foreign objects
causing overload on the motor.
Grinder impeller may be rubbing due to bent shaft or misalignment.
Pump On switch may be set too high.
Run pump on Hand operation for several minutes with small amount
of water running into basin to clean out solids and grease. This allows
pump to break suction and break up the solids.
Trash may have accumulated around lower weight causing
pump to turn o too soon. Clean the trash from the weight and
suspension
cable.
