chromates, boiler seal or other chemicals.
Warning:
No pressure reduction valve is required unless the water pressure exceeds
1,000 kPa
Warning:
Do not fit any valves, restrictors or obstructions to the outlet of the water
heater, or to the pressure relief located on the hot water outlet connection.
When water is required in one part of the system at a higher temperature than in the
rest of the system, means such as a mixing valve shall be installed to temper the water
to reduce the scald hazard.
Flush water through the pipe to clean out metal powder, sand and dirt before
connecting it.
Prevent from using joints as many as possible to keep the piping simple.
Failure to supply the proper pressure to the unit may result in noisy operation, shorter
life time of the unit, and may cause the unit to shut down frequently.
