ELECTRICAL CONNECTIONS

POWER REQUIREMENTS: 120 VAC, 60 Hz., 7 Amp. (Use a 15 Amp Circuit)

Always disconnect electric supply cord from the wall outlet or service disconnect before servicing this appliance. Observe all governing codes and ordinances when grounding, in absence of which, observe National Electrical Code ANSI / NFPA No. 70.

RECOMMENDED GROUNDING METHOD

This appliance is factory equipped with a power supply cord with a three- prong grounding plug (with polarized parallel blades). It must be plugged into a mating grounding type receptacle, connected to a correctly polarized 120 Volt circuit. If the circuit does not have a grounding type receptacle, it is the responsibility and obligation of the installer or user to have the existing receptacle changed to a properly grounded and polarized receptacle in accordance with all applicable local codes and ordinances by a qualified electrician. In the absence of local codes and ordinances the receptacle replacement shall be in accordance with the National Electrical Code.

THE THIRD PRONG SHOULD NOT, UNDER ANY CIRCUMSTANCES, BE CUT OR REMOVED (See Fig. 8 & 9).

ALTERNATE GROUNDING

METHOD

If installation of a properly grounded wall receptacle is impossible at the time of installation, consult your local electrical inspector for permission to connect a temporary adapter (with polarized blades) which could be plugged into your present 2-wire receptacle; however, this is not recommended. If this is done, you must attach the lug and/or the green adapter wire to the receptacle cover plate screw. Ground from it to a grounded metal cold water pipe* (See Fig.9). Do not ground to a gas supply pipe. You must permanently ground the adapter before connecting the appliance to the power supply.

CAUTION:

Attaching the adapter ground wire to wall receptacle cover screw does not ground the appliance unless the cover screw is grounded through house wiring.

If there is any doubt as to whether the wall receptacle is properly grounded, the customer should have it checked by a qualified electrician.

*Cold water pipe must have metal continuity. The electrical ground cannot be interrupted by plastic, rubber or other electrically insulating connectors (including water meter or pump) without adding a jumper wire at these connections (See Fig.10).
