Hartell Pumps A2 Owner's manual

Literature # 900040 2019
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 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 designed for grounded installation. 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 back up 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 A2. A2SA and AL2 series 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) years 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.

INSTALLATION
Carefully unpack the pump and select a location on the floor. The pump must be level and the inlet must be
below the lowest drain, either coil or furnace. Remove and discard the shipping pin that is located in the side
of the switch cover box. This releases the float for fully automatic operation. (Not used on A2SA)
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” NPT piping to the
discharge port. Extend this piping
or 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) 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.
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. Connect
the back and white wires to the appropriate voltage source and the green wire to ground.
Models with an “X” designation are equipped with a 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
In normal applications, this pump requires no scheduled maintenance for efficient operation. However, to
extend motor bearing life it is recommended that they be oiled every six months with S.A.E. 20. If a problem
develops, 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 not 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.
DISASSEMBLY (Omit Step 5 for “A” models) (Omit Step 4 for “AL” models)
1. Turn off power supply at fuse box and then drain water from reservoir.
2. Remove the four switch plate screws and carefully remove the switch/float assembly from the reservoir.
3. Remove the three impeller cover plate screws and loosen impeller cover plate.
4. Remove the four reservoir cover plate screws and remove the motor/cover assembly.
5. Remove the three motor bracket screws and remove the motor/bracket assembly.
6. Remove all debris from inside the reservoir and wipe with damp cloth.
REASSEMBLY
Apply a small amount of gasket sealer (e.g., Silicone, Permatex, etc.) around the impeller chamber and
reassemble by reversing the above procedure.
Keep these sheets with the pump. They may be valuable if service is needed under the terms of the warranty.
