Installation
Warning Sign
Mount warning signs in the spray area where they can easily be seen and read by all operators. An English Warning Sign is provided with the gun.
Ventilate the Spray Booth
Provide fresh air ventilation to reduce the risk of fire or explosion caused by the buildup of flammable or toxic vapors when spraying, flushing, or cleaning the gun. Do not operate the gun unless ventilation fans are operating.
Electrically interlock the gun air supply with the ventilators to prevent gun operation without ventilating fans operating. Check and follow all local, state, and national codes regarding air exhaust velocity requirements.
High velocity air exhaust will decrease the operating efficiency of the electrostatic system. Air exhaust velocity of 100 ft/min (31 linear meters/minute) should be sufficient.
