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.).

5Connect the hoses.

•Securely connect the hoses to the ports of the unit and the external water tank of the external open system so that the fluid does not leak. See the figure shown below. The outside diameter of both discharge (OUT) and return (IN) ports is each 13 mm.

Note) Connect the priming pump port (IN) to the return (IN) port of the unit.

•Using a solenoid or throttle valve to shut off the circulating path may result in malfunction of the circulating pump or fluid leakage.

•Do not throttle the path excessively. Keep a flow rate of the circulating fluid at 1.5·/min or over.

•Slowly change the flow rate. A rapid change in the flow rate may reduce the service life of the circulating pump.

Installation Procedure

6Connecting the power.

Confirm that the leakage breaker and the POWER switch are turned "OFF", and then plug into an outlet.

7Installing the external water tank (optional accessory)

Install the external water tank in a higher place than the unit. If it is installed in a lower place, the flow rate may drop or air bleeding may not be carried out smoothly when pouring the circulating fluid for the first time.

8Pour the circulating fluid into the water tank.

•Remove the lid from the external water tank, and pour the circulating fluid. (Select a circulating fluid in response to the set temperature condition.)

•Open the air release valve cock.

•Push the priming pump more than ten times.

(Feed the fluid from the external water tank to the circulating pump inside the unit to let out air from the pump. The fluid circulates after air is let out.)

•Turn on the leakage breaker and the POWER switch. (The circulating fluid flows into the fluid tank of the unit.)

•After the fluid tank is filled with the fluid, it is discharged into the external water tank.

(If the circulating fluid still does not circulate, immediately turn off the leakage breaker and the POWER switch. Check the unit according to the procedure described on page 43.)

•Close the air release valve cock.

The circulating pump may malfunction if the unit is operated with the circulating fluid uncirculated.

•After the circulation of the circulating fluid is stabilized, resupply the circulating fluid to 80% level of the external water tank.

•After the resupply of the circulating fluid is completed, turn "off" the leakage breaker.

•Replace the lid on the external water tank.

Exercise care not to allow the circulating fluid to get on the unit.If it gets on any electric part, leakage or electric shock may result. If it splashes on the operation panel, wipe it out.
