General precautions



 Power connection





 Power capacity

Determine the power capacity with reference to specification lists and wiring diagrams.

(Be sure to install a Molded Case Circuit Breaker (MCCB) suitable for the capacity at the

main power supply.)





 Rotation direction

OIL MATIC needs to be connected to the power supply such that an oil pump and a fan

motor in OIL MATIC make positive rotation. Since input terminals of the OIL MATIC power

switch are located in order of phases R, S, and T from the left side, connecting the phases

R, S, and T of the three-phase power supply to each of the terminals makes the rotation in

positive direction. (Since OIL MATIC is equipped with a reverse-phase protection relay, it is

not started in case of reverse phase.)





 Washing and cleaning

Wash the air filter regularly, at least twice a month (warm water, air-washing, etc.), to prevent it

from being clogged. (Also, clean the condenser fin unit at least once a year.)

 About OIL MATIC series V and KTV models





 Reservoir tank sizes

A reservoir tank in which the OIL MATIC series V and

KTV machines are installed will have larger plane

dimensions than OIL MATIC and the tank depth shall

be determined from the right table. Take into

consideration that the temperature will be

well-controlled if the tank capacity is equal to or larger

than three times the flow rate (L/min) of the liquid sent

from this tank.

(Note 1) A too small tank interferes with vortex motion and reduces the cooling capacity.





 Liquid level height

Keep the liquid level to the height that always makes the space between the bottom of a

chassis of the OIL MATIC series KTV/V models and the liquid level inside the tank, to be

30-100mm.

(Note 2) If the liquid level becomes lower than the specified level, then there is a possibility that dew is formed on the

cooling coil exposed in space and moisture may be mixed into the liquid. The low liquid level makes the cooling coil

exposed, which disables cooling of the liquid. For the OIL MATIC machines equipped with a heater, pay particular

attention to the liquid level to prevent the heater from operating without water, which is very dangerous.



 About water-cooled condenser

To use a water-cooled condenser-type OIL MATIC, piping work for

passing coolant, which is used to radiate condensation heat, will be

needed. The separate table shows coolant pipe diameters and required

flow rates.

*In terms of coolant quality, use soft water that causes little adhesion of

scales.

 About “OIL MATIC for coolant”

As the coolant for controlling temperature of the “OIL MATIC for

coolant,” use clean coolant filtered by a magnet separator, filter, etc. to

prevent failures caused by clogging of cooler, circulation pump, etc. from

occurring.
