Commissioning Procedure
1. Safety considerations for the commissioning:
Commissioning should be carried out by the person who installed the unit or by
the water system manager.
Make sure no-one touches the water (by washing hands, etc.) at the location
for water usage as this is a test operation as part of commissioning.
2. Checking each area before commissioning:
(1) Check the tightness of bolts and plugs.
Make sure that all joints for
flanges and plugs are tightened.
(2)
Check if valves are open or
closed.
・
Steam inlet valve (No. 9):
Closed
・
Steam control valve with
condensate separator (No. 10):
Closed
・
Condensate Blowdown Valve
(No. 5): Closed
Other valves on the water
supply system (not included with
the unit) should also be closed.
When starting up the unit, make sure to check the display for the
measured temperature and do not touch the hot water until the
temperature becomes stable as water at a temperature higher than
the set temperature may flow. Failure to observe these precautions is
dangerous and may result in burns.
CAUTION
The tank must be full of water before operating the heat exchanger.
In particular, if water has been discharged from inside the heat
exchanger for freeze prevention etc., make sure to restart the unit
after supplying water to the heat exchanger. Operating the heat
exchanger empty of water for a long period of time is dangerous,
and may result in the pump running dry and becoming damaged.
CAUTION
Operation should be carried out by an experienced person with
such as a steam and water piping technician or an electrician,
ensuring to wear a pair of leather gloves, helmet, protective glasses,
etc. to prevent burns. Failure to do so may result in burns, as the
piping and cover of the unit become hot during operation.
CAUTION
Install properly and DO NOT use this unit outside the recommended
operating pressure, temperature and other specification ranges.
Improper use may result in such hazards as damage to the unit or
malfunctions which may lead to serious accidents. Local regulations
may restrict the use of this unit to below the conditions quoted.
