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.\u003c\/li\u003e\n\u003cli\u003eThe 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.\u003c\/li\u003e\n\u003cli\u003eAllow 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.\u003c\/li\u003e\n\u003c\/ol\u003e","brand":"Nu-Calgon","offers":[{"title":"Default Title","offer_id":47344365535405,"sku":"4771-3","price":65.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0785\/5895\/3645\/files\/47713.png?v=1787907275","url":"https:\/\/www.bostonheatingsupply.com\/products\/nu-calgon-4771-3-no-220cp-poly-sprayer","provider":"Boston Heating Supply","version":"1.0","type":"link"}
