4. Open the valve on the Strainer and drain the boiler water from the Heater. It will be
necessary to loosen a Victaulic coupling by the Heat Exchanger to allow air into the pipe
during draining.
5. Next, connect a hose to the Drain Valve on the DHW Side of the piping assembly.
Remove the 1/4” plug on the side of the Strainer to allow air into the pipe during draining.
6. Open the Drain Valve to drain the domestic water from the Heater.
7. After the boiler water and domestic water have been drained from the Heater, replace the
1/4" plug removed in step 5 and tighten the Victaulic coupling loosened in step 4.
8. To prevent possible damage, ensure that all of the following precautions are observed:
 Under no circumstances should hydrochloric acid be used with STAINLESS STEEL
PLATES.
 Water of more than 300 ppm chlorine may not be used in the preparation of cleaning
solutions.
 It is very important that carrying bars and support columns in aluminum are protected
against chemicals.
 Do Not use brushes with carbon steel bristles or steel wool. A fiber type brush is
recommended. As a last resort, use a brush of similar material to the thermal plate. Be
careful not to scratch the plates or damage gaskets if they are to be reused.
 After brushing, rinse each plate with water.
 For better sealing, wipe all gaskets dry.
CAUTION
THE FOLLOWING SOLVENTS SHOULD NOT BE USED IN
CONTACT WITH GASKETS:
 KETONES (E.G. ACETONE, METHYLETYLKETONE,
METHYLISOBUTYLKETONE
 ESTERS (E.G. ETHYLACETATE, BUTYLACETATE)
 HALOGENATED HYDROCARBONS (E.G.
CHLOROTHENE, CARBON TETRACHLORIDE,
FREONS)
 AROMATICS (E.G. BENZENE, TOLUENE)
