ABG Heat Pump: How It Works
•The Hayward HP50HA Heat Pump provides the
perfect pool water temperature to enhance the
enjoyment of your pool throughout the
swimming season. This is achieved through
heating and cooling modes that work in concert
to achieve an ideal swimming temperature that
is user defined.
•With its 45,000 BTU heating capacity, this heat
pump is designed for small above ground pools
up to 13,000 gallons.
•It features a durable Titanium Heat Exchanger,
has an electronic thermostat control, and offers
quiet operation.

Follow these steps when attempting to test a capacitor (using an multi-meter).
How To: Check A Capacitor (multi-meter)
First, document how wires are attached
then remove all wires from capacitor.
Set multi-meter to ohms (60K range OR
highest possible option if less than 60K).
Touch one probe to one set of terminals,
and while looking at the meter touch the
other set.
For a slit second, the meter should show
are reading and return to OL or blank.
Step 1
Step 4
Step 3
Step 2
Step 5a For a slit second, the meter should show
are reading and return to OL or blank.
Step 5b
If the meter’s display never shows a
reading, then the capacitor needs to be
replaced.
Visual Clues Warranting a Capacitor Replacement
If capacitor is swollen.
If any of the posts/terminals are loose.
More than one instance of a burned wire connecting to a capacitor
