See diagram 7. - Terminate the steam line with a 1/2" NPT male adapter. Stub the line out into the room 9,5 mm from the fi nished surface. - Secure the steam line to a structural member. IMPORTANT If the steam line is in an area where the temperature will be below 4 C, if the steam line is me than 6 m long, best results can be obtained by insulating the steam pipe. WARNING Do not put a shut off valve in the steam line. Avoid traps and valleys where water could collect and cause a steam blockage. The hot steam line must be insulated against user contact. Centering the steam pipe is critical in rooms made of plastic, acrylic, resin, fiberglass similar materials. Allowing the steam pipes to touch materials not rated f 100 C higher will result in damage to these materials. Do not install the steam head near bench(es) where steam may spray where condensation will drip on the user as this will present a scald hazard. The steam pipe entry and any other entry into the steam room must be caulked to avoid damage caused by steam leakage into the wall. C: At the steam room: Locate each steamer's outlet(s) 380 to 460 mm above the nearest surface, at least 300 mm away from surfaces to the sides and at least 150 mm between each outlet fi tting. Keep all steam outlets as far from bathers as possible.

INSTALL PRESSURE RELIEF VALVE Install the pressure relief valve into its pt on the generat. The pressure relief valve outlet must drain in accdance with local and national codes. 6. INSTALL DRAIN VALVE Install a 76 mm long 1/2" pipe nipple (provided) directly into the tank as shown in diagram 8. Install the drain valve (Refer to Amerec's ADK Installation Instructions, document 4211-112, f me detailed instructions). Install a 1/2" union on the outlet side of the drain valve. Run a 1/2" copper drain line to a gravity fl ow drain. Do not run the drain uphill. HEATING ELEMENT ACCESS WARNING Do not connect the pressure relief valve output into the steam line. The pressure relief valve must be installed in such a fashion that the risk of scalding is reduced to a minimum. Draining the pressure relief valve into the steam room may present a scald hazard. Boiling water may be discharged from the drain. Proper precautions should be taken too insure safety. Do not connect the drain valve into the steam line. Draining the tank into the steam room may present a scald hazard and/ damage materials used to construct the steam room. DIAGRAM 11 The drain must be connected in accdance with local and national codes. SECTION 5: WATER REQUIREMENTS The nature of a steambath generat requires testing of the feedwater to avoid potential high concentrations of impurities which can cause a deposit scale to fm on the internal surfaces. This deposit scale can interfere with the equipment's proper operation and even cause premature generat failure. CONDUIT VALVE 76 mm NIPPLE Concentration of impurities is generally controlled by treating the feedwater and "blowing down" the generat when it is not heating. The "blow down" process involves removing a ption of the tank water with high solid concentration and replacing it with makeup water. To insure proper operation, the water supply should be tested pri to operating the equipment. There are several treatment processes which can be used if you have a problem with hard water. A local reliable water treatment company can recommend the appropriate treatment if required. The recommended feed water quality is listed below. Feedwater Quality Hardness, ppm 10-30 (0.5-1.75 gpg) T-Alkalinity, ppm 150-700 (8.75-40.8 gpg) Silica Range, ppm 15-25 (1.28-1.45 gpg) IMPORTANT! Regular maintenance will help your steamer wk properly f a long time. Check f leaks, loose damaged wires, signs of crosion and calcium build up in the tank on the level probe. This is particularly imptant in areas with high calcium levels and other water quality problems. Calcium build can cause po steamer perfmance and damage the heating elements!
