Dayton Operating Instructions and Parts Manual

Models 3WY47, 3W735B, 3W736C, 3WY44, 3TE27A, 3WY45, and 3WY46

Operation

HIGH AND LOW TEMPERATURE OPERATION

Air temperature affects generator output. Output drops 1% for each 10° tempera- ture rise above 60° F. Very low tempera- tures may make the engine hard to start. See engine ownerÕs manual for more information.

GENERAL INFORMATION

This generator is not large enough to power your entire home. Do not connect generator to any existing electrical circuits. Plug items directly into generator recep- tacles. Do not exceed amperage rating of receptacles. Only use grounded cords.

Use only in well- vented areas. Make

sure area has plenty of free-moving, fresh, outside air. Never run generator in an enclosed or confined area. Never run generator inside occupied building. Engine exhaust contains poisonous carbon monoxide gas. Overexposure will cause loss of consciousness and will lead to death.

Never connect generator to any

existing electrical circuits. The genera- tor output will back-feed into the utility power line. This may electrocute a power company line repair person. Also, if generator is powering electri- cal circuits, the chance of an electrical fire exists.

NOTE: We supply the engine ownerÕs manual with generator. Refer to that manual for questions concerning engine operation.

USING RECEPTACLE

NOTE: Do not exceed amperage rating of receptacles. Exceeding rating will trip receptacle circuit breaker.

Use receptacles properly. Improper use could damage generator. Use only grounded extension cords. Power only grounded or double-insulated items. Do not overload receptacles. Models 3W736C, 3WY44, 3WY46, 3TE27A, and 3WY45 have the following receptacles (See Figure 21):

¥120V, 15-amp duplex receptacle

¥120V, 15-amp duplex GFCI receptacle

¥120V, 30-amp twist-lock receptacle

¥120/240V, 20 or 30-amp twist-lock receptacle

Model 3W735B has only the 120V duplex receptacle.
