INSTALLATION • OPERATION • MAINTENANCE

NTRODUCTION

HARTELL LTS and LTP are general-purpose reservoir pumps developed for laundry and wet bar
applications. These models are utilized to pump wastewater from an area with no floor drains to
an overhead or remote drain line. The pump must be installed in conjunction with a (laundry) tub/
sink. This pump has been carefully engineered to provide long, trouble free service and is of the
highest quality workmanship and materials.

These pumps have been thoroughly inspected and tested, then carefully packaged to insure safe
delivery and operation. When you receive your pump, examine it carefully to determine that there
are no damaged or broken parts. If damage is detected, notify the firm from where the pump was
purchased. They will assist with a repair or replacement.

See the precautions listed below before continuing.

CAUTION: READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING INSTALLATION

- Pump should only be used with liquids compatible with pump component materials. Do not use
to pump flammable or explosive fluids. Do not use in explosive atmospheres.

- The pump is supplied with a grounding type plug. To reduce the risk of electrical shock be
certain that it is connected to a properly grounded, grounding receptacle.

- Do not handle pump with wet hands or when standing on a wet or damp surface, or in water.

- Shut off the electrical power at the fuse box before making any connections. All wiring must
comply with local codes.

- A strainer must be installed in the tub to prevent foreign objects, (buttons, screws, etc.), from

entering and damaging the pump. In laundry applications a lint trap must be installed to prevent
an excessive build-up of lint that could interfere with proper float/switch and impeller operation.
A nylon stocking works well as a lint trap.

- Applying heat directly to the tank with a torch, or indirectly by heat transfer through copper
tubing can melt the tank. This will void the warranty. Solder fittings and tubing first, allow to cool,
and then assemble to the tank. The use of some pipe dopes will soften and/or crack the plastic
used in this pump. This will void the warranty. Use only Teflon tape when installing threaded
fittings to the tank.

ONE YEAR LIMITED WARRANTY

HARTELL LTP and LTS waste water pumps are guaranteed to be free from defects in
workmanship or materials and to function satisfactorily, when properly installed, for a period of
ONE (1) year from date of installation. HARTELL will replace, without charge, any HARTELL
product found to be defective upon examination at our factory if returned within the guarantee
period, transportation charges prepaid.

This guarantee does not apply if the product has been misapplied or mechanically damaged,
HARTELL assumes no liability for resultant damages of any kind arising out of the use of its
products.

Keep these sheets with the pump. They may be valuable if service is needed under
the terms of the warranty.

INSTALLATION

1. Place the pump in the desired location under the tub/sink.

2. Install the piping necessary to connect the drain to the 1 ½” inlet. A trap is
recommended. The use of unions or slip fittings is also recommended to
encourage proper pump maintenance. Install the vent line and run it over the top
and into the tub/sink. This allows proper venting of the tank and the discharge of
soap foam back into the tub/sink in laundry applications.

3. A check valve is required and should be of a soft seat swing check design. A

spring loaded ball check is permissible if the lift is one half of the pump shut off

level and the spring pressure is equal to, or less than one (1) psi.

4. The installation of a shutoff valve is recommended in the discharge line. This will
allow the discharge flow rate to be modified, if required to match inlet flow and
prevent short cycling of the pump in low lift installations. In addition, it will allow
service to the check valve or the pump without draining the discharge line.

ELECTRICAL CONNECTIONS

Plug the pump into a properly grounded electrical receptacle. A ground fault style
receptacle or breaker is recommended. Alternatively, the power cord can be removed
and the pump hard wired into an existing circuit. Be sure to follow all applicable
electrical codes.

OPERATION

The LTS & LTP pumps operate automatically. Water from the tub/sink drains into the
tank where it raises the float to a pre-set power on point. The water is pumped out
the discharge and through the check valve to the drain line. The float drops with the
water level to a pre-set power off point. The check valve keeps the water from
draining back to the tank.

MAINTENANCE

The majority of maintenance is preventative. Keep foreign objects out of the inlet and
tank by using an inlet screen and lint trap. Be aware that the vent line, check valve,
and discharge piping contribute to system performance. Turn off power to the pump
before performing any maintenance or tests.

To inspect the tank interior and float/switch, remove the five (5) switch screws that

attach it to the tank. Inspect and clean the float as required. If the tank requires
cleaning the pump must be
removed from the plumbing lines first. Remove the eight (8) perimeter screws and lift
the motor and top portion of the tank as a single unit from the tank bottom. Inspect
and clean as required
including O-ring of impeller chamber cover and tank perimeter seal. Reverse the
above procedure to assemble. Be sure all seals, gaskets and O-rings are in place
and not pinched. Replace if worn or not sealing.

Tub/sink use, water conditions, soap and cleaning agents will impact the frequency of
maintenance required. Establish a maintenance procedure and follow it to prevent

system-related problems.

TROUBLESHOOTING

Problem Probable Cause

Pump does not run
when water is poured
into the sink/tub.

- check that pump is plugged in

- check power to outlet or circuit

- fuse/breaker blown or tripped

plugged in with no
water in tub/sink.

- damaged float/switch

- float “hanging-up” on tank wall due to buildup of soap scum or debris

- check valve leaking back to tank

Pump runs but doesn’t
empty sink/tub

- clogged discharge line

- ball check valve spring pressure too high

- lift too high and/or run is too long (shutoff @ 13’ LTP & 16.5’ LTS)

Pump leaks around
motor and/or float/
switch

- damaged float/switch

- discharge too high

- discharge clogged

has water standing in
stink/tub.
