INSTALLING THE POOL HEATER
Pool Heater installation is divided into two sections:
electrical connections, and pool piping
connections.
The Factory has fully installed the refrigeration loop and preset the controls. There are
no job-site installation requirements for the heat pump.
Wiring should only be done by licensed
electricians.
ELECTRICAL CONNECTIONS
Power to the Pool Heater
The AQUEFIER Pool Heater requires a separate 230 volt, 50 amp. circuit with a breaker, and a
ground connection. The pool heater grounding conductor shall be the same size or larger than the
live power supply conductors. See Figure 1 – Electrical Connections. For reference see Figure 3A,
Pool Heater 230 VAC Schematic.
Use a length of watertight flexible conduit to connect to the Pool Heater cabinet. Enter the Pool
Heater cabinet through the openings provided at the right /rear corner of the cabinet. Remove the
control box cover panel and connect directly to the
compressor contactor
inside the control box.
Ground the heat pump per local codes.
This pool heater is to be installed in accordance with Article 680 of the National Electrical Code,
ANSI/NFPA 70, and with the requirements of the authority having jurisdiction.
Bonding to Pool Steel:
Electrical corrosion, known as electrolysis, will occur if the heater is not
bonded to the pool reinforcement steel. Most local codes also require that the water pump be
bonded. Connect using a #8 gauge or larger solid copper wire to bond the cabinet to the pool
reinforcement steel.
Power to the Pool Pump
An optional feature on the Aquifier Pool Heater is the
Pump Hold Relay
. Since
the pool heater
can
not run without water flow
, the
Pump Hold Relay
will keep the pool pump and the pool
heater running until the pool has reached the desired temperature setpoint. If the pump hold relay is
not wired in, the heater can only run when the pump is either turned on manually, or by the pump
timer.
To wire this optional feature in, the pool heater requires a circuit from the pool pump timer to the
pool heater, and a circuit from the pool heater to the pool pump. See Figure 2, Pool Pump to Hold
Relay Wiring Schematic. The Pump Hold Relay can be used with either a 120 volt or a 230 volt, 1
phase pump, with current draws up to 25 amps. It should be noted that power to the pump can be
supplied by the Timer and the Pump Hold Relay at the same time. The polarity of both sources of
power to the pump must be the same. See Figures 1 and 2. The power supply to the timer and the
pump hold relay must come from the same breaker.
