Light Commercial Condensate Removal Pumps
INTRODUCTION
HARTELL condensate pumps are designed to collect and automatically remove the water produced from an air
conditioner evaporative coil and/or a gas-condensing furnace. 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 distributor where the pump was purchased from. 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.
–In any installation where property damage and/or personal injury might result from an inoperative or
leaking pump due to power outages, discharge line blockage, or any other reason, a backup system(s)
(aux. switch) and/or alarm should be used.
–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.
ONE YEAR LIMITED WARRANTY
HARTELL PABX condensate 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.
See our website for additional warranty information at www.hartell.com.
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.

INSTALLATION
Carefully unpack the pump and select a mounting location on the wall, the case of the air conditioner, or floor. The
pump must be level and the inlet must be below the lowest drain, either coil or furnace. If wall or case mounting, use
the mounting tabs on either side of the reservoir to secure the pump.
PIPING—Run flexible tubing or pipe from
the evaporator and furnace to the pump.
Insert the pipe into the drain inlet hole.
Make sure the pipe does not interfere
with the float. Cut an angle on the inlet
pipe so that it doesn’t close off against
the bottom of the pump. See Figure 1 –
exploded detail.
Connect 3/8” ID tubing to the barbed
check valve. Extend this tubing straight
up as high as necessary. (Do not extend
this tubing past the head/GPH of the
pump installed). Do not kink the tubing,
as this will block the flow. From this high
point, slope the discharge tubing
downward to a point above the drain,
then turn down and extend to a point
below or level with the bottom of the
condensate pump. If it is not possible to slope the discharge tubing downwards, make an inverted “U” trap directly
above the pump at the highest point. (Figure 1)
ELECTRICAL CONNECTIONS—review precautions on previous page
LINE VOLTAGE—Connect power cord to the proper voltage as indicated on the motor nameplate. Connect only to a
source of constant power, not an intermittent source such as a fan or limit
control circuit.
LOW VOLTAGE—AUXILIARY SAFETY SWITCH–Connect the leads of
auxiliary safety switch to the thermostat control circuit of the air
conditioner/furnace. This will disrupt the thermostat demand in a high-
water condition. (Figure 2) CAUTION –Thermostat demand disruption
should not be utilized if cooling or heating requirements are a necessity.
An alarm system should be used with the auxiliary switch instead.
OPERATION
After proper installation, the operation of the HARTELL condensate pump is automatic. Water is collected in the
reservoir and pumped out when the float raises to a pre-set point. As the water level goes down the float turns off
the motor at another pre-set point. Under most circumstances the pump requires little maintenance for efficient
operation. If a problem occurs, please refer to the maintenance instructions below.

MAINTENANCE
Visually inspect this pump seasonally to ensure there is no buildup of any kind inside the unit. If any problems
develop, or a buildup is seen during visual inspection, the following guidelines can help to return the pump to
service.
PUMP DOES NOT RUN
–Check to see that the power to the system (air conditioner and/or furnace) is on to allow production of condensate.
–Check that the pump is plugged in and the circuit is active (i.e. fuse or breaker not blown).
–Check the level of water in the reservoir; the level must be within 2” of the reservoir top to activate the switch.
(The inlet tube may be blocked and require cleaning if no water is entering the reservoir).
–If there is a proper amount of water in the reservoir, the float may be stuck due to dirt or algae formation. (Flush
the reservoir with warm water and a mild soap or detergent). See note below.
PUMP MOTOR RUNS WITH NO DISCHARGE
–Inspect the discharge tubing for its full length to make sure it is clear; make sure the tubing end is not plugged.
–Make sure the check valve is not clogged. (If clogged, UNPLUG THE PUMP, remove the fitting and clean with mild
soap or detergent). See note below.
–The discharge port of the impeller chamber may be clogged due to an accumulation of debris. (See instructions
below on how to disassemble unit and clean chamber).
NOTE: In case of extreme algae formation, UNPLUG THE PUMP, and fill the reservoir with a commercially available
algaecide. Follow directions for destroying the algae. After the proper waiting period DUMP the algaecide out of the
reservoir. Rinse with water, repeat if necessary. Be careful not to clog the check valve when starting the pump after
this thorough cleaning.
CLEANING Under most circumstances the pump requires little maintenance for efficient operation. If a problem
occurs, please refer to the maintenance instructions below.
DISASSEMBLY
–UNPLUG THE PUMP; drain the water from the reservoir
–Place the pump upside down; place a screwdriver under
the tab of the baseplate, (put a thumb over the tab to
prevent breakage), and pry the cover up and off. (Figure 3)
–Remove the “O” ring seal and keep it clean. (Figure 3)
–Remove any debris from the impeller chamber and spin the
impeller by hand to insure free movement.
Keep these instructions with the pump. They may be valuable if service is needed under the terms of the warranty.
ASSEMBLY
–Clean and lightly lubricate the “O” ring with vegetable oil
–Stretch the “O” ring onto the baseplate (Figure 3)
–Place the tab of the baseplate into the slot of the reservoir
base; hold the tab in place with the thumb and snap the cover
into the reservoir with the heel of the hand; tap the cover with
a plastic mallet if required to fully seat it. (Figure 4)
–Test for leaks; if a leak occurs, re-install cover using a new
“O” ring if necessary.
