v General Information

The HARTELL LTA-1 model pump is a completely self-contained unit designed to
remove wastewater from sinks when a traditional gravity drain line is not available.
Popular applications include; wet bar sinks, kitchenettes, utility sinks, and laundry tray
sinks. Lightweight and compact, the LTA pump mounts directly to the drain tailpiece of
your sink, eliminating all traps and inlet piping. The LTA design does not require any
connection to the main stack vent
systems. The LTA pump’s rugged construction, automatic operation, and ease of
installation provides the best value in a drain pump that will provide many years of
trouble free service. Proper installation practices will ensure virtually maintenance free
operation, and extend the life of your pump.

Installation Note: All pumping and piping systems will fail at some point due to a
variety of reasons including power failures, foreign objects, neglect, or “old age”. Proper
safeguards, and precautions such as alarms, safety switches, drain pans, etc. should be
installed with any system when system failure will result in damages to finished living
spaces. It is the responsibility of the installer to make appropriate provisions for system
failure consistent with each specific installation.

! WARNING

Risk of electrical shock. This pump is supplied with a grounding type
cord and plug. Do not modify cord or plug. Plug pump into a properly grounded,
grounding type, GFCI receptacle, following all local codes.

! WARNING

Risk of electrical shock. Do not handle pump, cord, or plug with wet

hands, or when standing in water or on a damp surface, when pump is plugged in.
Unplug pump before servicing or performing any maintenance. Do not work with
energized electrical equipment in a wet area. Reasonable care and safe practices
should be exercised during installation and maintenance.

! CAUTION

Pipe dope and other thread sealing compounds must not be

used to aid in the sealing of inlet or discharge threads. Pipe dope
will cause cracking of plastic parts. Use Teflonä tape only to aid in

thread sealing. Use of pipe dope will void warranty.

v Installation

1. Attach pump to sink drain tailpiece as follows:

a) Place fiber gasket over drain threads.
b) Place rubber o-ring over drain.
c) Lift pump and engage inlet threads with the sink drain threads. Exercise care

so that threads are properly aligned. Mis-alignment will damage threads and
may cause leaks.

d) Rotate the pump until tray adapter flange on pump inlet contacts the foam

gasket. Once contact is made, rotate pump until it is firmly secured to the
drain and the discharge is in the correct position for your installation.

2. Install discharge piping as shown in Figure 1.

a) 1” piping and valves are recommended; however 3/4” piping and valves

may be substituted in installations where lift requirements are less than six (6)
feet, or approximately one half of the pump’s maximum lift.

b) A check valve or back flow preventer (included) is required to ensure the

proper operation of the pump. A soft-seat, swing check valve is included;
however, a ball or spring type check valve may be used if the force required
to open them is no more than 3 feet of lift, or less than 1 psi. and does not
affect the required pump flow.

c) A discharge line shut-off or balancing valve (included) is required to

regulate the discharge flow to match the sink drain flow. This will minimize
cycling of the pump and allow cleaning and servicing of the check valve
without draining the discharge line.

3. Plug pump into a properly grounded, grounding type receptacle.

Follow all local codes. GFIC is recommended.

! CAUTION

A strainer must be installed in the sink drain to prevent debris and
foreign objects from entering and becoming lodged in the pump
chamber, preventing proper pump operation. If used with a washing
machine a lint trap or tube filter should be used on the washing
machine discharge hose.
