Prevention of Damage due to Freezing
When draining 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
components 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 the unit 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.
Draining procedure
1. 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.
3. 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.
