Error and Display Codes:
See Table 13: Display Code Index
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”).
WARNING:
These instructions are intended for the use of qualified personnel trained and experienced in the installation and servicing
of this type of heating equipment and its related system components. Some states may require installation and service personnel to be
licensed. Persons not qualified should not attempt to repair this equipment according to these instructions. These instructions and pro-
cedures 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 fire.
Never operate heater with the pump shut off.
NOTICE:
As a preliminary check, make sure that all wire connections are clean and tight and that all wiring conforms to the wiring diagram.
FUSE SPECIFICATIONS:
The fuse designations are printed on the power board and the ignition control board. See Figure 20: Control Assem-
bly Components for board locations. Fuses are available as common hardware items or may be purchased from manufacturer in a service
parts kit. The fuse specifications are:
F1 fuse (low voltage): 3A blade style fast-acting automotive fuse, type 257
FC1 & FC2 (transformer primary) and FC4 (transformer secondary):3A slo-blo fuse, 5 x 20 mm
INTERNAL WIRING:
If the heater display is blank after the electrical has been installed, refer to
Troubleshooting Lookup Chart
to determine
the cause. Note, the ribbon cable between the display board and the ignition control board is keyed to ensure correct connection.
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 not fire. If there is no call for heat, the UI will continue to display the water temperature when the pump is off. No “LO”
code will be displayed. If there is a call for heat and the pump is off, an “LO” fault code will be displayed until the pump turns on. There will be a
2 minute delay after the water pressure switch is closed for the heater to fire. After the pump has primed, this wait can be avoided by manually
clearing the error code via the keypad by changing the mode through the “STANDBY” setting and returning to the initial setting (“SPA” or
“POOL”).
WARNING:
Pool heaters are heat producing appliances. To avoid possible over heating of the outer jacket and damage or injury with
such an event: (1) no materials should be stored against the jacket and (2) care should be taken to avoid unnecessary contact
(especially by children) with the jacket.
WARNING:
When lighting a gas heater, the lighting instructions must be followed exactly to prevent “flashback” of excess gas in the
heater. Electronic ignition heaters and electric heaters must have the power shut off when making adjustments for servicing, or coming
into contact with the heater.
WARNING:
UNDER NO CIRCUMSTANCES SHOULD FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT THINNERS, BE
USED OR STORED IN THE VICINITY OF THE HEATER OR IN ANY LOCATION FROM WHICH FUMES COULD REACH THE HEAT-
ER.
