Table 7.2-1 Daily check items
Check the installation
condition of the
product.
・Check that there is no heavy object on the product or
excessive force appying to the piping.
・Temperature should be within the specification range
of the product.
・Make sure the ventilation grille is not obstructed.
(For air-cooled type)
Check piping
connections.
Check that there is no fluid leakage from the connected
parts of the piping.
Amount of
circulating fluid
Check the fluid level
gauge.
Fluid level should be between "HIGH" and "LOW" levels
of the fluid level gauge.
Check the indications
on the display.
The display on the screen is clear.
Circulating fluid
temperature
Check on the touch
panel.
There should be no problem for operation.
Circulating fluid
discharge
pressure
Check on the touch

7.2.2 Monthly check
Table 7.2-2 Contents of monthly check
Ventilating condition
(air cooled type)
Clean the ventilating
grilles.
Make sure the ventilating grilles are not clogged
with dust, etc.
Cleaning of air ventilation port (Air cooled type.)
Clean the dust-proof filters with a long bristled brush or by air blow to prevent
the fins from being deformed or damaged.
If the fins of the air-cooled condenser become clogged with dust or
debris, heat radiation performance declines. This will result in the
reduction of cooling performance, and may stop the operation
because the safety device is triggered.
