Winterizing the Equipment

Vapor-Abrasive Blasters must be winterized whenever there is a possibility of freezing temperatures during storage. It is imperative that you anticipate the possibility of a freeze and always protect the unit during fall and winter seasons, even if being stored only overnight.

1.Make sure all of the water has been drained from the pot. Reconnect the abrasive hose after draining the pot.

2.Make sure the pot bung is in the closed position. This will prevent debris from entering the pot during storage.

3.Drain the water tank by disconnecting the pump inlet hose and opening the inlet ball valve.

NOTE: All disposals must comply with national, state, and local regulations. In addition, if the water contains a rust inhibitor, you may want to retain and preserve the water due to the expense of the inhibitor.

4.Drain the pump inlet hose, then insert the end into a windshield wash container. Choose a windshield wash with a rating that will protect the equipment for the lowest temperatures in your area.

Operation

5.Turn the selector valve to RINSE and open the rinse ball-valve. While holding the rinse hose over the pot, run the pump until windshield wash comes out of the rinse hose.

6.Move the selector valve into the other three positions (WASH, BLAST, and FILL). Confirm that the internal water tubing fills with windshield wash before turning the selector valve to the next position.

NOTE: All 3/8 in. tubing should be filled with windshield wash for full protection.

7.Engage the Emergency Stop.

8.Reconnect the pump inlet hose to the inlet ball valve.

9.Add 1–2 gallons (4–8 liters) of windshield wash to the water tank. Make sure that the rinse ball-valve and the drain ball-valve are left open.

NOTICE

When ice forms behind the seals, the seals can become damaged. During storage, position all ball-valves in the open position.
