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

which is common with other types of drain pump
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.
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.
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.
