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:NOTE:
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.
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). Conrm
that the internal water tubing lls with windshield
wash before turning the selector valve to the next
position.
NOTE:NOTE:
NOTE:
All 3/8 in. tubing should be lled 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.
