Unit installation

REQUIRED BONDING TO POOL STEEL
Make sure that the unit cabinet is bonded to the pool
steel. Most codes require that the circulation pump be
bonded as well. You can connect at that point using at
least a #8 gauge or larger solid copper bond wire. Use
the external bond lug on the cabinet to insure a good
bond.
Bonding the unit to the pool steel will help reduce the
chance of electrolysis, also know as electrical corro-
sion. A heater left un-bonded may experience corro-
sion to the metal water tubing inside the heater. Do
not confuse with electrical ground.
START CAPACITOR FOR
208 VOLTAGE
The compressor must be protected from low voltage
situations to meet the warranty requirements. A unit
drawing high amps due to low voltage, is not consid-
ered a proper installation. Contact the factory service
for advise about low supply voltage. Many coastal com-
munities have 208 volts. 208 volt supply requires
changing transform leads to 208V from 240V, see
wiring schematic.
TIME DELAY COMPRESSOR
NOTE: The compressor will attempt to start after a 5 to
7 minute time delay has passed from when the unit was
activated. If the compressor starts then shuts right off,
allow the 5 to 7 minute time delay to pass before expect-
ing the compressor to start.

ELECTRICAL WIRING GROUND &
EQUIPMENT COMMON BONDING
A certified electrician should prepare to wire the heater according to national, local codes and specifications from
the factory in regards to supply voltage and amperes. Most codes require that a power disconnect be placed near
the heater for emergency shut off.
Inform the owners not to use the circuit breaker as
the on/off switch or the unit will not preheat as
needed between cycles. Turn the thermostat all the
way down when you do not want the unit to heat.
WIRE SIZE & GROUNDING
SEE SPECIFICATION SHEET TO DETERMINE
REQUIRED BREAKER AND WIRE SIZE.
The heater must be electrically grounded and bonded
in accordance with local codes, or in the absence of
local codes, with the latest national electrical codes
ANSI/NFPA No. 70. All wiring must comply with all
local codes, or in the absence of local codes, with the
latest national electrical codes ANSI/NFPA No. 70.
For proper wire and/or breaker size, please refer to
specification sheet and your local licensed electrician.
