PRESSURE SWITCH

The pressure switch, or heater actuator, ensures that the heater operates only when the filter pump is in operation. It is factory set at 1.75 PSI for deck level installations. When the heater is located below the level of the spa or pool it may be necessary to reset the pressure switch to compensate for the no-flow static head. If it is necessary to reset the pressure switch, we recommend the following procedure:

PRESSURE SWITCH ADJUSTMENT:

1.Make sure the pool filter is clean before adjusting the switch.

2.Set the heater control to the OFF mode.

3.Turn the filter pump on and confirm that the pressure switch is closed (use a multimeter to check). If the pressure switch fails to close, either the switch setting is too high or the filter pump is not supplying enough pressure.

4.Turn the heater ON.

5.Manually turn the pressure adjustment knob clock- wise until the heater shuts off. (A flat screw driver may be necessary if knob is too tight).

6.Slowly turn the adjustment knob counter-clockwise until the heater calls for heat again.

7.Turn an additional 1/2 turn counter-clockwise.

8.While the heater is running, check the adjustment by turning the pump off and on several times. The burners should shut off immediately when the pump is turned off. If it does not, repeat the above steps until proper operation is observed.

5' Max

NOTE: If heater is installed outside of the limits shown, a flow switch must be used in place of the pressure switch when mounted and wired adjacent to the heater.

TWO SPEED PUMPS

In some cases, the flow on the low speed is insuffi- cient to operate the heater. This is apparent when the pressure switch cannot be further adjusted or if the heater makes banging noises. In these cases, the pump must be run at high speed when heating the water.

CAUTION: Do not operate the heater without a function- ing and properly adjusted pressure switch.

HIGH LIMITS

The heater is equipped with two automatic high limits. Set to operate at 135°F and 140°F.

NOTE: An erratic high limit is often characteristic of internal heat exchanger problem, i.e. scale build-up, U.G. operation. Refer to troubleshooting sections.

HIGH LIMIT REMOVAL

1.Shut off main electrical power switch to heater.

2.Remove inspection panels.

3.Drain heater.

4.Remove defective high limit and replace with a new high limit.

5.Reverse above procedure to re-install.

PILOT SAFETY

The heater employs a pilot safety which closes the main gas valve within 8/10ths of a second whenever the pilot flame is interrupted. Pilot flame is automatically lit when the device is powered. Unit performs its own safety check and opens the main valve only after the pilot is proven to be lit.

BURNER DRAWER REMOVAL

1.Shut off main electrical power switch to heater.

2.Shut off gas upstream of heater.

3.Remove front door.

4.Disconnect gas line from gas valve.

5.Remove (2) screws that mount burner tray to unit, and (2) screws that secure gas valve to jacket.

6.Disconnect wires that terminate at gas valve.

7.Slide out burner tray.

8.Reverse above procedure to reinstall.
