Grounding
Grounding
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 F
Have a qualified electrician connect the grounding wire
to the generator. Check with national electric code for
grounding of mobile electric units. Be sure your installation complies with all National, State, and Local safety
and fire codes.
IG. 7.
Transporting Trailer
• Do not run generator while trailer is in motion.
• Do not exceed the gross vehicle weight requirement. See Technical Data on page 45.
• See warnings in trailer manual. See Related Man-
uals on page 3.
1. Read trailer manual before transporting or loading
the trailer. See Related Manuals on page 3.
2. Follow Pressure Relief Procedure, page 26.
3. Follow Short-Term Shutdown procedure, page 28.
4. Ensure that drums are properly secured into drum
holders. Tighten drum straps to ensure that they
don’t move during transport.
5. Lock tool cabinet and secure all loose articles in
trailer.

Power Sources
The trailer has two options for power sources. Generator
Power uses the electricity provided by the generator to
provide power to all of the components and outlets in the
trailer except for the 12V lights. Shore Power uses electricity from an external source, supplied through the
Shore Power extension cord, to provide power to certain
outlets in the trailer.
NOTE: Shore Power outlets are labeled with a plaque.
Outlets Powered by Shore Power in 20 ft Trailers

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.
The right air pressure regulator supplies air to gun via
the proportioner and should be set according to air inlet
recommendations in the gun manual. See Related
Manuals on page 3. Verify both regulators are set correctly. Fill ISO pump lube reservoir as required.
