Commissioning Procedure
When starting up the unit, make sure to check the display for the measured
temperature and do not touch the water until the temperature becomes
stable at a temperature higher than the set temperature may flow.
Failure to observe these precautions is dangerous and may result in burns.
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.
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 heat-resistant 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.
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 below the conditions quoted.
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.
