Nu-Calgon 4771-3 No. 220CP Poly Sprayer

Directions

1. Inspect sprayer, and insure the hose is securely attached to the tank and to the shut-off handle.
2. Remove the pump from the tank by turning counter clockwise.
3. To minimize foaming when preparing a cleaning solution, add water to the tank before adding the cleaning solution. Fill tank to fill line on side of tank.
4. Close tank by inserting pump assembly through opening. Turn cap right (clockwise) until pump is sealed tightly into the tank (hand-tighten only).
5. Pump plunger to compress air and create pressure in tank. Twenty strokes of plunger provides a good working pressure. As pressure drops during use, recharge with 20 or more pump strokes. More strokes will be needed if the tank is not full, or as the sprayer is used and the pressure drops.
6. The nozzle tip may be adjusted to provide a single-needle stream (tip screwed all the way out) or a fine mist (tip screwed all the way in). Spraying time will vary from about 5 minutes with the needle spray to about 12-15 minutes with the fine mist. The needle spray should be used on finned coils to reach the third and fourth banks better. The mist is better for cleaning permanent filters.
7. Allow the cleaning solution to remain in contact with the dirty surface for about 15 minutes, then flush with water from a hose. If a hose is not available, fill the sprayer with water and flush using a course spray.
