Installation introduction Installation of expansion water tank and priming valve 1 Install priming valve at the proper position of the upper end of water pump connection tube of solar station. The valve has no directionality. But the installation space must be convenient for late priming. 2 Install one tee at the outlet of the priming valve. One end of tee is connected with circulation water output tube and another end is connected with expansion water tank. 3 After determination of its position, drill two holes in the wall with percussion drill. The hole is 70mm in depth and 9mm in diameter. Then fix expansion water tank on the wall with two expansion bolts and corresponding fixing strap. Notice Priming valve and expansion water tank are both installed on the corresponding tubes at the water output of water storage tank. Priming antifreeze 1 Screw off the priming vent cap of priming valve, close the bigger check valve in the middle of priming valve ( when two blades on the valve handle is vertical to axle of valve, it is closed) and open another two smaller check valves. 2 Connect the output of priming equipment with one priming inlet and ensure the flowing direction is the same with installation direction of check valve. Then Connect another priming output with returning inlet of priming equipment. Start the priming equipment for priming. 3 Observe the returned antifreeze until uniform returned flow and no bubble is realized. At first close the check valve connected to returning inlet of priming equipment, then the check valve connected to outlet of priming equipment, and open the bigger check valve in the middle of priming valve. Disassemble the priming equipment. Notice After priming, put 3/4 fibre gasket in the priming inlet cap and tighten it to prevent the leakage of antifreeze. • The antifreeze used in the Circulation Pipe must be in conformity to local safety and environmental protection standards or laws. • The antifreeze must be primed by the qualified technician of Haier. • The disposal of the antifreeze must be in conformity to local safety and environmental protection laws. • The antifreeze may evaporable, flammable and toxic. If find leakage of it, contact the local after-sale sectors immediately. If drink or suck it by accident, contact the medical institution and see the doctor immediately. If the skin contacts the antifreeze accidently, wash it away and contact the medical institution and see the doctor immediately. 6 Haier solar water heater
