5InstallationProcedure InstallationPrecautions for InstallationNote) 1. About the specified liquid level range1) During cooling operation with the liquid level lower than the specified range, the moisture of the atmospherecondenses on the exposed part of the cooling coil, causing the condensate to be mixed into the liquid.If the liquid level further decreases, it results in cooling capacity deterioration, and also causes a fault of theunit.2) During heating operation the liquid level lower than the specified range, the heating element of the heater isexposed or discolored, or may emit burning smell. If the liquid level further decreases, the heater activates theoverheat protection device. This condition hinders normal operation, and also causes a fault of the unit.3) If the liquid level falls below the specified range due to liquid level fluctuations during operation, the liquid over-flows from the tank. To prevent the above 1) to 3) problems, be sure to maintain the liquid level within thespecified range.∗Mount a float switch to ensure that the liquid level in the tank is within the specified range.2. Give thorough consideration to the layout of the partitions and inlet/outlet piping for the installation tank, so thatthe low-temperature liquid that has been cooled with the OILCON unit can be uniformly mixed with the high-tem-perature liquid returned from the machine.Installation place and oil piping To install this unit, select a place that meets the following conditions: Do not place an object that may block air flow within 500 mm from the air intake/exhaust port.1. Level, rigid floor (Inclination: 5˚ max.)2. A place where the unit is not exposed to direct sunlight or heat3. A place with proper ventilation and little humidity4. A place where exhaust air does not circulate (exhaust air willnot be taken into the unit)5. A place that allows easy access to piping and wiring6. A place with little contaminant, waste, dust particles oroil mist7. A place free from explosive atmosphere (evolution, inflow,retention or leak of inflammable gas)ObstacleExhaust air500 mm or more500 mm or more 500 mm or moreIntake air(Front)Obstacle Obstacle40 to 100 mm(Specified liquid level range)Liquid levelLegH(Tank depth)AgitatorCooling coilHeaterTank(Prepared by user)OILCON(Oil cooling unit)50 mm or more(From tank bottom surface)OILCON overall heightFloor surfaceA (Tank width)*For “A” and “H”, see page .6 |
