SPRING START-UP – CONSULT A PROFESSIONAL:
1. Inspect and clean the heater, being sure the heater is free of leaves and debris prior to startup.
2. Be sure inlet and outlet piping are properly attached to the heater and the drain valve is closed.
3. Turn the filtration system pump "ON" and allow the system to run long enough to purge all the air
from the lines.
4. Turn the gas supply to the heater "ON".
5. Set the temperature control using the keypad to "POOL" or "SPA" and adjust the set point to the
desired temperature setting.
6. If operating difficulties are encountered, contact a qualified service company for assistance.

Information
On initial trial for ignition. Automatic reset is immediate once the gas valve
relay check results are acceptable.
If valve is open when it should be closed the heater will shut down and go into
lockout. Blower will operate until error condition is corrected. Automatic restart
2 minutes after error is corrected.
If valve is closed but flame is sensed the blower will run for 5 s then start a new
ignition sequence. If error occurs 10 times during a call for heat the control will
go into lockout. Automatic reset is 60 minutes.
If control input data is corrupted the heater will shut down and go into lockout.
If flame is sensed with the gas valve off the control will go into lockout. The
blower will run until error condition is corrected. When corrected, control will
run blower for 5 s then automatically restart after 2 minutes.
This code will display if 120V polarity is reversed, low voltage is detected, or if
the ground path is not sufficient. Reset is immediate after error is corrected.
If the blower prover switch does not close after the blower starts the control will
stop the ignition trial go into lockout. The blower will continue to run. Automat-
ic reset is immediate after the switch closes.
If the blower prover switch opens unexpectedly during operation the control will
