Winterize the Equipment
1. Drain the pot. Perform the Drain the Pot procedure,
page 26.
2. Drain the water tank by disconnecting the pump
inlet hose and opening the inlet ball valve (N).
NOTE: All disposals must comply with national,
state, and local regulations.
3. 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.
4. Turn the selector valve to WASH 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.
5. Move the selector valve 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.
6. Engage the emergency stop (Q).
7. Reconnect the pump inlet hose to the inlet ball valve
(N).
8. Make sure that the rinse ball valve (X) and the inlet
ball valve (N) are left open.
