Hartell A3X Guide

A3X / A5X
Commercial Condensate Removal Pumps
I N S T A L L A T I O N & O P E R A T I O N
Introduction
The Hartell A3 & A5 series condensate removal pumps are designed to collect and automatically remove the water pro-
duced by air conditioner evaporator coils and/or steam humidier units (for use with water up to 212°F). As designed, the
pump will collect water in its integral reservoir. After enough water has been collected, an internal oat switch activates
the pump and water “pump-out” will begin. Once enough water has been evacuated from the reservoir, the pump will
automatically de-activate and wait to begin the cycle again.
As with all Hartell products, the A3 and A5 series of pumps have been carefully engineered to provide long-term, trouble-
free service. Thorough factory testing of each pump ensures your pump has been built with the highest quality workman-
ship and materials.
READ ALL INSTRUCTIONS BEFORE INSTALLING PUMP!
FAILURE TO FOLLOW WARNINGS & CAUTIONS COULD
RESULT IN BODILY HARM AND/OR PROPERTY DAMAGE!
WARNING! WARNING! WARNING!
• WARNING! To reduce the risk of electrical shock this pump must be grounded with a properly wired grounding con-
nection.
• WARNING! Disconnect electrical power at the power source (fuse box, circuit breaker, etc.) before servicing pump!
• WARNING! DO NOT handle the pump with wet hands; or, while standing on a wet/damp surface or in water.
CAUTION! CAUTION! CAUTION!
• CAUTION! Pump should only be used to pump liquids compatible with pump component materials. DO NOT use to
pump ammable or explosive uids. DO NOT use in explosive atmospheres.
• CAUTION! In any installation where property damage and/or injury could occur as a result of an inoperable or leaking
pump, a back up system such as high level safety oat switch and/or alarm is highly recommended.
• CAUTION! For correct wiring installation, refer to the enclosed wiring diagram.
• CAUTION! THE A5X PUMP SERIES MUST BE SUPPLIED BY A DEDICATED 20 AMP SERVICE AND BREAKER
TO HANDLE CURRENT DRAW DURING MOTOR START-UP.
• CAUTION! Make certain that line voltage corresponds to voltage specied on pump motor’s nameplate.
• CAUTION! ALL WIRING MUST CONFORM TO LOCAL ELECTRICAL CODES. In areas where local codes are non-
existent, the National Electrical Code applies.

ONE YEAR LIMITED WARRANTY
HARTELL A3/A5 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) 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 liabil-
ity for resultant damages of any kind arising out of the use of its products.

Installation
1. Carefully unpack & inspect the pump. Examine it to ensure that no damage has occurred. If damage is observed, notify the rm where the pump
was purchased. They will assist with repair or replacement.
2. Determine which inlet is to be used. If the optional side inlet is to be used, the factory installed cap must be removed, and the loose cap supplied
with the pump must be installed over the top inlet to prevent foreign objects from falling into the reservoir. Use the clamp from the side inlet to se-
cure the top inlet cap. DO NOT REMOVE THE SIDE INLET CAP UNLESS THE SIDE INLET IS TO BE USED!
3. Position the pump so that the inlet chosen is close to and below the drain line. The pump MUST BE LEVEL!
Plumbing Connections
4. Connect a suitable drain line from the evaporator coil drain to the pump’s inlet. Ensure a downward slope of the line in order to provide proper
gravity drainage into the pump.
5. Connect the properly sized copper tubing to the discharge port’s check valve assembly. Do not run piping higher than 80% of the recommended lift
for the pump. For proper drainage of the discharge line, any horizontal run should have a downward slope.
Wiring Connections
6. WARNING! Disconnect electrical power at the power source (fuse box, circuit breaker, etc.) before servicing pump!
7. CAUTION! THE A5X PUMP SERIES MUST BE SUPPLIED BY A DEDICATED 20 AMP SERVICE AND BREAKER TO HANDLE CURRENT
DRAW DURING MOTOR START-UP.
8. CAUTION! All wiring to the pump must conform with local electrical codes. In areas where local codes are non-existent, the National Electrical
Code applies.
9. CAUTION! Make certain that line voltage corresponds to voltage specied on pump motor’s nameplate. For proper installation, connect pump only
to a constant source of power. Connection to an intermittent power source will not allow for proper pump operation
10. Once voltage and power source is veried, connect the green lead to ground, and the two brown leads to either hot or neutral.
11. In the event that electrical compartment connections are removed for pump service, refer to the wiring diagram below or on inside of electrical com-
partment cover to make proper connections.

13. CAUTION! Replace pump’s electrical compartment cover & re-install screws.
14. HIGH WATER LEVEL SAFETY SWITCH: This product is supplied with a factory installed auxiliary safety switch. (See Figure 1 for its location in
pump assembly.) This switch is a passive protective device providing protection from the possibility of pump overow due to clogged discharge
lines or pump malfunction. These switches are wired to work as an alarm trigger, but can be changed to act as a circuit breaker depending on the
application requirements.

Pump Test
Check for proper pump function.
1. Remove the drain line tubing from the pump inlet.
2. Pour water into the pump’s inlet until the pump turns on.
3. Pump should evacuate water then turn off. It will leave about ¾” of water in the
tank after “pump-out” is complete.
4. Reconnect the drain line tubing to the pump inlet.
Operation
When properly installed, the operation of the HARTELL pump is automatic. Under
most circumstances, the pump requires little maintenance for efcient operation. If a
problem occurs, check the following items or consult with the rm where the pump was
purchased.
WARNING! Disconnect electrical power at the power source (fuse box, circuit breaker,
etc.) before servicing pump!
ITEMS TO CHECK
• Check inlet and outlet piping for blockage or kinks that would inhibit ow
• Make sure oats move freely.
• Make sure the pump impeller casing is not clogged
• Make sure the check valve is not clogged.
Keep this sheet with the pump. It may be valuable if service is needed under the terms of the warranty.

The auxiliary safety switch is wired in the “normally open” position enabling
use as a trigger to close the circuit powering an external alarm system in the
event that the water inside the reservoir rises to a level where overow of the
pump is imminent.
OPTIONAL – Circuit Breaker Function – Normally Closed Wiring – (Fig-
ure 3)
The auxiliary safety switch is wired in the “normally closed” position and can
act as a circuit breaker to interrupt power to or disable the appliance or equip-
ment that is producing the condensate (heater, air conditioner, humidier, etc.)
!!CAUTION!! This option must not be used if cooling, heating or humidica-
tion requirements are critical.
15. Turn electrical power to pump on.
