4.1Remote control transceiver PCB installation

Warning: For safety reasons, disconnect the power supply to the water heater before performing installation.

Pre-installationpreparation

B Disconnect power supply to heater.

B Remove plastic decals on front panel.

B Loosen two Philips head screws located behind plastic decals.

B Lift front cover upward and remove.

Fig. 2

B Remove the 5 screws on the front retaining bar (see Fig. 2, pos. 1 and 2) being careful not to damage the foam sealant material on it.

B Remove control unit auxiliary cover (Fig. 2, pos. 4).

B Remove the two electrical strip connectors inside the auxiliary cover (Fig. see diagram below) and then loosen the 110V power supply cord retaining nut located underneath the heater. Once loosened, the power cord can be pulled up through the heater to provide sufficient slack.

Remote control installation

Once auxiliary cover is off, pull off the two electrical strip connectors from the board. Once off, the wiring harness can be removed from the case by pulling their rubber seals outward.

Electrical strip connectors

BAt the ignition electrodes, pull off the 2 yellow igniter wires that come from the top of the control unit (Fig. 2, pos. 3). Then pull the complete control unit forward and out of the heater, pull up the power supply cord further if more slack is needed.

BWhile holding the unit in one hand or resting it on a flat surface, remove the front cover of the control unit by removing the 4 screws.

Remote control transceiver PCB installation

BOpen control unit top cover (Fig. 3, pos. 1).

BRemove the protective paper (Fig. 3, pos. 2) from one face of the support

and attach it to the main PCB as shown in Fig. 4.

Fig. 3

BRemove the other protective paper and attach the remote control PCB as shown in Fig. 5.

BUse the supplied cable to connect between the main PCB and the remote control PCB as shown in Fig. 5.

BReplace the control unit cover with the 4 Philips head screws (Fig. 3, pos. 1).

B Slide control unit back into heater.

BPlug 2 yellow electrode wires from the top of the control unit back onto the ignition electrodes. Ensure all connections are secure and tight (Fig. 2, pos. 3).

Wire polarity does not

imatter on the electrode wires.

B Pull end of power cord to take up excess slack and tighten retaining nut on the bottom of the heater.

B Reinstall the two electrical strip connectors onto the PCB. The larger connector connects to the lower connection on the PCB. Reseat the rubber seals for both connectors.

B Replace the control unit auxiliary cover. (Fig. 2, pos. 4).

BReplace front retaining bar using 5 Phillips head screws. (Fig. 2, pos 1).
