6. Prevention of damage due to freezing
When discharging water from the unit, make sure to wait until the
unit has cooled down.
If carrying out work after hot water use, there is a risk of burns, as the unit
and the water inside the unit are hot.
Make sure measures are taken to prevent freezing of the unit
’s steam piping
system in cold climates. If a component is damaged due to freezing, repair will
be charged even within the warranty period.
Water in the water supply system cannot be discharged with the unit. To prevent
freezing of water supply system, contact the administrator of the water system.
(1) Draining procedure
Make sure that the steam inlet valve (No. 9) is closed and
the unit has completely stopped and cooled down.
(2) Open the condensate blow valve (No. 5) of the PowerTrap
unit to discharge steam condensate. Make sure to close the
valve after confirming the steam condensate has been
drained completely. Mistakenly leaving the valve open is
dangerous, as steam or condensate may be discharged
during operation start-up.
