Grounding Grounding Transporting Trailer See grounding procedure and related warnings in supplied manuals. See Related Manuals on page 3. • • • The trailer must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. When grounding the trailer, ground to one of the bolt holes on the rear, side of generator block. See FIG. 7. Have a qualified electrician connect the grounding wire to the generator.
Setup Setup NOTE: Shore Power outlets are labeled with a plaque. Outlets Powered by Shore Power in 20 ft Trailers • • See setup procedure and related warnings in supplied manuals. See Related Manuals on page 3. • The left two outlets of the 4-gang outlet in the main room, on the driver side wall of the trailer The two-plug outlet in the main room to the left of the electrical panel, on the partition wall The outlet (W) in the generator room Power Sources The trailer has two options for power sources.

Setup Shore Power Generator Power Shore Power can be used to provide power to certain outlets in the trailer. The powered outlets can be used to run low amperage items. When using Generator Power, all outlets in the trailer are hot, including Shore Power outlets. 1. Turn off main breaker. 1. Turn main breaker off. 2. Turn Shore/Generator Power Switch (AF) to the “OFF” position. See FIG. 12. 2. Turn generator off. 3. Turn Shore/Generator Power Switch (AF) to the “OFF” position. See FIG. 10.
Setup Air Regulators Assembly The left air pressure regulator on the air regulators assembly (F) supplies air to the transfer pump and should be set according to air inlet recommendations in the transfer pump manual. Pump fluid outlet pressure may vary based on air inlet pressure. Verify the fluid outlet pressure meets proportioner fluid inlet recommendations in Proportioner manual. See Related Manuals on page 3.
Setup Air Conditioning 1. Verify Air Conditioning breaker is in the “ON” position. 2. See setup instructions in Air Conditioning manual. See Related Manuals on page 3. Breathable Air System See setup instructions and related warnings in supplied manuals. See Related Manuals on page 3. 1. Verify breathing air filter system is plugged in. 2. Set setup instructions in Breathable Air System manual. See Related Manuals on page 3. Band Heaters See setup instructions and related warnings in supplied manuals.
Startup Startup See startup instructions and related warnings in supplied manuals. See Related Manuals on page 3. Start Generator NOTE: Refer to generator operator’s manual for cold weather startup instructions. 8. Press and hold bypass button. Prepare for Generator Startup 1. Ensure main breaker for the generator is in the OFF position. The main breaker is the only breaker located in the generator room. 2. Turn Shore/Generator Power Switch (AF) to the “GEN” position. 3.
Startup Start Trailer Components 12. Turn on main breaker in the generator room. 13. Verify voltage and frequency displayed on the digital voltage/amp meter. With engine at normal operating temperature and not under load, voltage should be 220V +/- 1% and frequency should be 60Hz +5%/-2%. 14. Start proportioner. See Proportioner manual for instructions, see Related Manuals on page 3. 15. Start compressor. For all non-screw compressors, engage starter. Verify readout on air pressure gauge on compressor.
Pressure Relief Procedure Pressure Relief Procedure Chemical Pressure Relief 1. Turn off feed pumps and agitators if used. See pressure relief procedure and related warnings in supplied manuals. See Related Manuals on page 3. Generator pressure must be relieved prior to performing generator maintenance or repair. See generator manual. 2. Turn off proportioner. 3. Relieve pressure in gun and perform gun shutdown procedure. See Gun manual. See Related Manuals on page 3. 4. Relieve pressure in proportioner.
Operation Operation See operation instructions and related warnings in supplied manuals. See Related Manuals on page 3. Trailer Interior Lights 120V Lights The trailer interior lights on the walls and the fluorescent light under the cabinet (if installed) can be powered by either Generator or Shore Power. To use these lights, setup Generator Power or Shore Power, see Setup on page 19. There is one light switch for the 120V lights in each room.
Shutdown Shutdown 8. Run generator unloaded for at least two minutes to allow engine to cool. See generator operator’s manual for details. See shutdown instructions and related warnings in supplied manuals. See Related Manuals on page 3. 9. Turn generator ignition switch to the off position. 10. Turn Shore/Generator Power Switch (AF) to the “OFF” position. Short-Term Shutdown 1. Turn off proportioner. Refer to proportioner manual for shutdown procedure. See Related Manuals on page 3. 2.
