Before Using This Unit
Requirements for Installation
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 receptacle which is supplied appropriate power and voltage.
9. Use a proper circulating fluid in response to working conditions
• Select a circulating fluid according to the working temperature.
Set temperature + 10°C or over: Water
Set temperature + 10°C or below: Antifreezing fluid (Nybrine
® - 60%, ethylene glycol - 50%)
If water is used at the set temperature of + 10°C or below, the cooling coil may freeze to cause
malfunction.
10. When using a Nybrine aqueous solution instead of water
• The freezing point of the antifreezing fluid depends on its concentration or type. Use an
antifreezing fluid having a 10°C lower at least than the working temperature. Any antifreezing
fluid, which freezes at a higher temperature than that, may freeze in the cooling unit and
deteriorates heat exchanging efficiency.
11. Do not use fluids other than water and antifreezing fluids (Nybrine
®
, ethylene glycol)
• Pour distilled water or tap water into the water tank. Water of poor quality may cause fur or
scale to accumulate on the heater pump, which may result in deteriorated performance or
malfunction (e.g. well water, etc.).
• A circulating fluid with high specific gravity or highly viscosity places overburden on the
circulating pump and damages the unit (e.g. Fluorinert, Galden, etc.).
• A corrosive fluid or a fluid that produces corrosive substances when heated may cause
malfunction (e.g. Fluorinert).
• Do not use any fluid whose vapor is toxic or hazardous because it may result in an accident
(methyl alcohol, etc.).
