Winterizing a MistAway Gen II (PRO-CAP or Smart Cap) Tankless Unit

1. Flush coupler, dosing pump and insecticide flow line first with clean water and then with air.

b. Execute a Manual Charge to flush the dosing pump and line with clean water.

(MAINTENANCE Menu, INS, than hold down SELECT knob and the AUTO/ON/OFF button simultaneously for a period of 5 seconds.)

c. DOSE and a countdown will be displayed. The unit will run the dosing pump for an extended period, flushing insecticide out of the pump and line with clean water.

d. Remove PRO-CAP or Smart Cap from bottle and snap it by itself into Smart Coupler.

e. Execute another Manual Charge (same routine as above) to pump air through and evacuate fluid from insecticide flow line.

d. Allow the unit to run until the batch tank is empty.

3. Evacuate remaining fluid from inlet water line and pump discharge line.

a. Disconnect nozzle circuit from unit.

b. Use the INSpect function to open the inlet supply and agitation valve. Unit will think it is trying to fill tank with water. (MAINTENANCE Menu, INS, hold down SELECT knob for 5 seconds.)

c. Lift right side of unit about 4” to let water run out of valve and flow meter.
