Before Using this unit
Requirements for Installation
7. Before/after installing
It may cause injure to a person if this unit falls down or moves by the earthquake and the
impact. etc..To prevent, take measures that the unit cannot fall down, and not install to busy
place.
Though this unit has the air-cooled refrigerator, the device exhausts the heat. Do provide
the vaporization with enough so as not to raise the ambient temperature caused by the
exhaust of the heat, or install this unit with its air controlled completely. If the ambient
temperature becomes high, the operation efficiency becomes worse, and could cause the
malfunction of the device by high temperature and humidity.
8. Handling of power code
Do not entangle the power cord. This will cause overheating and possibly a fire.
Do not bend or twist the power cord, or apply excessive tension to it. This may cause a fire
and electrical shock.
Do not lay the power cord under a desk or chair, and do not allow it to be pinched in order to
prevent it from being damaged and to avoid a fire or electrical shock.
Keep the power cord away from any heating equipment such as a room heater. The cord's
insulation may melt and cause a fire or electrical shock.
If the power cord becomes damaged (wiring exposed, breakage, etc.), immediately turn off
the power at the rear of this unit and shut off the main supply power. Then contact your
nearest dealer for replacement of the power cord. Leaving it may cause a fire or electrical
shock.
Connect the power plug to the receptacl which is supplied appropriate power and voltage.
9. Before/after installing
Connect the circulation port of the main
body to the coolant device securely so
as not to leak cooling liquid.
Closing the circulation path with the
solenoid valve or throttle valve might
cause the malfunction of the pump such
as water leakage.
Please open the stop valve discharge
and the return at the time of the pump
driving by all means.
Pay attention to the over-throttle. Keep
minimum flow rate of circulating solution
more than 10% of Pump Max.Flow Rate
according to Specification Table on
page 26.
In case that there are solenoid valve on
the device to be performed the
circulation cooling, or in case that the
flow rate of the device is lower than the
1.5 liter per min. set the bypass circuit
between the main device and peripheral
devices.
