Usage Precautions
CAUTIONS
Failure to observe the instructions contained in a CAUTION may result in injury or physical damage.
Do not feed incorrect liquid into the unit.
This chiller is designed to operate with fresh water (compliant with the water standards
developed by the Japan Refrigeration and Air Conditioning Industry Association, see page
26) or with an ethylene-glycol water solution that has a concentration of 30 to 40%. If you
are using pure water, use water with an electrical conductivity of 1
μ
S/cm or higher. Input
of a different type of liquid may damage the equipment and may lead to liquid leakage,
electric leakage, and electric shock.
Do not try to operate the chiller with the cooling water circuitbeing closed.
Such practice can cause failure on the compression pump leading to leakage of the
cooling water.
Do not sit on, lean on, or place objects on this equipment.
Overturning of equipment may result in injury or spillage. Spillage may in turn result in
electricity leakage.
Do not use flammable sprays in the vicinity of this equipment.
Also, do not place flammable objects in the vicinity of this equipment. Sparks generated by
switch action may ignite flammable material.
Don't touch the fin when cleaning the condenser.
Otherwise can result in personal injury.
Don't insert your fingers or a rod into the blowout or suction port.
Otherwise personal injury can result from a fan that is revolving at high speed inside the
cooler.
Periodically check that the leakage breaker is working correctly.
A defective breaker may fail to trip in event of electric leakage, leading to risk of electric shock.
Be sure to include this operating manual if transferring thisequipment to
another user.
If you sell or otherwise transfer this equipment to another user, tape this manual onto the
equipment so that the new user is sure to notice it. New users must read this manual to
ensure that they can operate this equipment safely.
