Specific Product Precautions 5
Operation Restart Time/Operation and Suspension Frequency
Caution
1. Wait five minutes or more before restarting operation
after it has been stopped. If the operation is restarted
within five minutes, the protection circuit may acti-
vate and the operation may not start properly.
2. Operation and suspension frequency should not ex-
ceed 10 times per day. Frequently switching be-
tween operation and suspension may result in the
malfunction of the refrigeration circuit.
Protection Circuit
Caution
If operating in the below conditions, the protection
circuit will activate and an operation may not be
performed or will stop.
Power supply voltage is not within the rated voltage range of
±
10%.
In case the water level inside the tank is reduced abnormally.
Circulating fluid temperature is too high.
Compared to the cooling capacity, the heat generation amount
of the user’s equipment is too high.
Ambient temperature is over 45
°
C.
Ventilation hole is clogged with dust or dirt
Maintenance
Caution
<Periodical inspection every one month>
Clean the ventilation hole.
If the dustproof filter of water-cooled type product becomes clogged
with dust or debris, a decline in cooling performance can result.
In order to avoid deforming or damaging the dustproof filter, clean
it with a long-haired brush or air gun.
<Periodical inspection every three months>
Inspect the circulating fluid.
1. When using tap water or deionized water
Replacement of circulating fluid
Failure to replace the circulating fluid can lead to the
development of bacteria or algae. Replace it regularly
depending on your usage conditions.
2. When using ethylene glycol aqueous solution
Use a concentration meter to confirm that the concentration
does not exceed 15%.
Dilute or add as needed to adjust the concentration.
<Periodical inspection during the winter season>
1. Make water-removal arrangements beforehand.
If there is a risk of the circulating fluid freezing when the
product is stopped, release the circulating fluid in advance.
2. Consult a professional.
This product has an “anti-freezing function”, “warming-up
function”, and “anti-snow coverage function.” Read the
Operation Manual carefully, and if any additional anti-freezing
function (e.g. tape heater) is needed, ask for it from the vendor.
