Operation

Connecting the Blast Hose and Air Hose

3.Open the air supply valve (125 psi, 8.6 Bar, 0.86 MPa maximum). If necessary, use a regulator in the supply air line to meet these specifications.

1.Always purge the air supply hose 15–20 seconds before connecting the air supply hose from the compressor (or on-site compressed air source) to the panel. Make sure all debris is cleared from the hose.

2.Connect an appropriately sized air supply hose to the air inlet. See Technical Specifications, page 45.

NOTE: Make sure the air supply meets the appropriate air flow requirements. See Technical Specifications, page 45.

4.Connect the blast hose, hose restraints, control hoses, and coupler pins.

NOTE: Make sure to properly install hose restraints and coupler pins to the quick-coupler and the air line. If the holes on the quick-coupler do not align, there is something wrong and the two couplers are not compatible. DO NOT TURN ON THE AIR. Seek help to get the situation resolved.

NOTE: If you are using an electric blast control, check all of the electrical connections from the panel to the blast control.

NOTICE

Make sure no electrical connections will be exposed to water. Exposure to water could cause a short circuit and damage the equipment.
