MODEL LTA-1 (802210)
INSTALLATION • OPERATION • MAINTENANCE
READ ALL INSTRUCTIONS
Pump turns on and off (“cycles”) when no
water is in the sink.
BEFORE STARTING INSTALLATION
™General Information
Pump turns on and off (“cycles”) rapidly
when sink is full or at maximum water flow.
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.
-Balancing valve not adjusted properly.
(Pump will cycle with faucets partially on. This is normal and will not harm pump.)
Lightweight and compact, the LTA pump mounts directly to the drain
tailpiece of your sink, eliminating all traps and inlet piping.
™Service and Maintenance
The LTA design does not require any connection to the main stack vent1
which is common with other types of drain pump systems.
The LTA pump is designed to be virtually maintenance free when used in
accordance with the installation guidelines specified in these instructions.
Installation and preservation of an inlet screen will prevent excessive
accumulation of material in the pump chamber and possible obstruction of the
impeller by foreign objects such as stones, string, buttons, etc.
Before returning the unit for replacement, the pump housing should be removed
and the impeller chamber checked for obstructions.
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.
To check impeller, Unplug pump and remove from
sink. Remove four (4) ¼” hex head screws from
the “fins” of the housing as shown in figure 2.
Separate housing from motor base plate and
inspect for obstructions. After clearing any debris,
replace housing on the base plate making sure
that the rubber “o” ring is in place around the
