(1) Water Tank
(2) Relief Valve
(3) Filler Plug
(4) Air Valve
(5) Ball Valve
(6) Water Spray Nozzle Ball valve (5) controls the flow of water to the water hose and water spray nozzle (6). When the water cleaning system is not being used, ball valve (5) should be shut off. After ball valve (5) is shut off, the pressure in the water hose should be released through water spray nozzle (6).Fill
Do not remove the fill plug until the pressure in the water tank has been relieved. Personal injury may result.This fill plug has a cross drilled hole that allows the pressure to be relieved without disengaging the threads.Do not replace this fill plug with any other plug.
In order to fill water tank (1), release pressure in the system through water spray nozzle (6).
Unscrew filler plug (3) for two turns counterclockwise. After the pressure is relieved, remove the filler plugs.
Fill water tank (1) with water. The total volume of water tank (1) is 34 L (9 US gal). Water tank (1) will hold 25.5 L (6.75 US gal) of water and 8.5 L (2.2 US gal) of air. Note: If the outside temperature is below freezing, use a propylene glycol-based antifreeze in the water tank. The antifreeze should be a non-toxic antifreeze that is used in recreational vehicles.
Install filler plug (3) and pressurize water tank (1). Pressurize the Water Tank
Water tank (1) is pressurized to 345 kPa (50 psi). In order to pressurize water tank (1), connect an air hose to air valve (4). Relief valve (2) limits the tank pressure to 345 kPa (50 psi).
