Winterize The Equipment; Use The Water Dose Meter - Graco EcoQuip 2 EQm Instruction Manual

Operation

Winterize the Equipment

Vapor abrasive blasters must be winterized whenever
there is a possibility of freezing temperatures during
storage to avoid damage to the equipment.
1. Drain the pot. See Drain the Pot, page 25.
2. Disconnect the water inlet regulator from the pump
and install the winterizing tube. Insert the winterizing
tube into a windshield washer fluid container.
Choose a windshield wash with a rating that will
protect the equipment for the lowest temperatures in
your area.
3. Turn the selector valve (T) to WASH and open the
rinse ball valve (U). While holding the rinse hose
over the pot, run the pump until windshield wash
comes out of the rinse hose.

4. Move the selector valve (T) into the other two
positions (BLAST and OFF). Confirm that the
internal water tubing fills with windshield wash
before turning the selector valve to the next position.
NOTE: All water tubing should be filled with windshield
wash for full protection.
5. Engage the emergency stop (L).
6. Make sure that the rinse ball valve (U) is left open.
When ice forms behind the seals, the seals can
become damaged. During storage, position all ball
valves in the open position.

Use the Water Dose Meter

The water dose meter is a feature that allows the user to
adjust how wet the blast will be during operation.
1. Perform the Adjust Abrasive Media procedure,
page 19.
2. Adjust the water dose valve (N) to adjust how wet
the blast will be during operation.
