3. While checking for leaks care must be taken to prevent solution from
contacting the electrical connections at the control. If electrical connections
at the control become wet, they must be thoroughly dried before attempting
to operate the water heater.
Electrical Connections
All electrical wiring and connections must be in accordance with the National
Electric Code ANSI/NFPA No. 70 (latest edition), or the Canadian Electrical
Code C22.1 (latest edition) and any local codes which may apply. The water
heater must be electrically grounded.
If a flexible line cord and plug is permitted by local code, then provide a 3 wire
grounding type receptacle within 6 feet
(1.9 m)
of the water heater and use the
flexible cord provided. Do not plug the line cord into a receptacle that can have
its power supply interrupted by a switch that is used to turn on and off lights.
If wiring in conduit is required, cut the flexible line cord flush with the bushing.
Remove the junction box cover and pull the pressure switch outside of the
junction box. Cut the three wires from the line cord at the bushing inside of the
junction box. Drill a hole to receive the 1/2 inch
(1.3 cm)
electrical conduit
connector on the backside of the blower. Wire the power supply into the circuit
at the appropriate locations. Replace the pressure switch and junction box
cover.
CAUTION
Turn off or disconnect the electrical power supply to the water heater before
servicing. Label all wires prior to disconnection when servicing controls.
Wiring errors can cause improper and dangerous operation. Verify proper
operation after servicing.
