The surface temperature of the water pipe would be very high, depending on the set temperature. Insulate the pipe
to prevent burns. When operating PWFY-P100, P200VM-E1-AU with cold water, insulate the water pipe to prevent
condensation.
Wrap insulation material around water pipes as shown in [Fig. IV. 3.(6).1].
• Any heat source piping.
• Indoor piping in cold-weather regions where frozen pipes are a problem.
• When air coming from the outside causes condensation to form on piping.
• Any drainage piping.
