6. Prevention of damage due to freezing
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.
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.
