GENERAL:
ATTENTION:
These instructions are intended for the use of quali
fi
ed personnel trained and experi-
enced in the installation and servicing of this type of heating equipment and its related system compo-
nents. Some states may require installation and service personnel to be licensed. Persons not quali
fi
ed
should not attempt to repair this equipment according to these instructions. These instructions and
procedures are not for the use of “do-it-yourself” consumers.
WARNING: BURN HAZARD
The operation of the heater with the pump shut off
could cause heater overheating and
fi
re. Never operate heater with the pump shut off.
ATTENTION:
As a preliminary check, make sure that all wire connections are clean
and tight and that all wiring conforms to the wiring diagram.
AUTOMATIC RESET TIME:
The heater will automatically reset when an error condition is corrected and resume operation. The heater
can be manually reset using the keypad by cycling the MODE button through STANDBY and back to the
original operating mode (POOL or SPA).
SUPPLY WIRING:
If the heater is connected to the
line
side of the circuit it will be powered at all times. In this situation,
when the pump shuts down the heater will display a fault code of “LO”. If there is a call for heat and the
pump then restarts there will be a 2-minute delay for the heater to
fi
re. After the pump has been running for at
least 2 minutes there is no delay for heater operation.
Wiring the heater to the load side of the timer or controller will not result in a 2-minute delay if the pump
primes quickly enough to activate the heater’s water pressure switch. If the pump is slow to prime the heater
may display an “LO” fault code and will take 2 minutes to automatically restart. If the pump has primed,
this wait can be avoided by manually clearing the error code via the keypad by cycling the mode through the
STANDBY setting and returning to the initial setting (SPA or POOL).
When a heater is wired to the line side of the power circuit (continuous power) the blower will not operate
when the pump is cycled via a time clock or other switch method.
INTERNAL WIRING:
If the heater display is blank after the electrical has been installed, re
fer to Figure 21 and Figure 22 to
d
etermine the cause. The ribbon cable between the display board and the ignition control board is keyed and
cannot be inserted upside down if it was removed when electrical was done.
FUSE SPECIFICATIONS:

control board. See Figure 15 for board locations. Fuses
are available as common hardware items or may be purchased from Hayward in a servi
ce parts kit. The fuse
speci
fi
cations are:
