Maintenance and Inspection
When disassembling or removing the unit and its components, wait until
the internal pressure equals atmospheric pressure and the surface of the
components have cooled to room temperature.
Disassembling or removing components when hot or under pressure may lead
to discharge of fluids, causing burns, other injuries or damage.
When conducting an inspection during operation of the unit, it should be
carried out visually wearing protective glasses, being careful not to touch
the piping, etc.
Failure to do so may result in burns, as the piping and cover of the unit become
hot during operation.
Take measures to prevent people coming into direct contact with the
condensate outlet of the unit.
Failure to do so may result in burns or other injury from the discharge of fluids.
Be sure to use only the recommended components when repairing the
unit, and NEVER attempt to modify the unit in any way.
Failure to observe these precautions may result in a damage to the unit or
burns or other injury due to malfunction or the discharge of fluids.
Make sure the power switch is OFF before carrying out work on the wiring
or inspections involving disassembly.
If such work is carried out with the power on, there is a danger that unit may
malfunction or electric shock may occur, leading to injury or other accidents.
Make sure that wiring work requiring a special license is carried out by
qualified personnel.
If carried out by unqualified personnel, overheating or short circuits leading to
injury, fires, damage or other accidents may occur.
There are two types of inspection to be carried out for maintenance of the unit,
daily inspections and periodic inspections.
・
Daily inspection:
Check visually and by sounds from the unit to judge for
abnormal conditions.
・
Periodic inspection: Skilled maintenance personnel should carry out disassembly
of the necessary components for inspection.
1. Daily inspection
For trouble-free use of the unit, please check and record the following items on
a daily basis.
If inspecting the back of the unit, make sure to wear appropriate safety gear
(helmet, safety shoes, gloves etc.) and be careful of hot piping.
(1) Water/steam leakage
Check for any traces of leakage from valves,
flanges or pipe fittings during operation.
(2) Pressure gauge (No. 19)
If the facility manager has indicated the acceptable
pressure range on the pressure gauge, check that
the pressure is within the range.
