* When operating at 1 liquid temperature 20 ° C, ambient temperature 32 ° C, cooling water temperature 32 ° C. The cooling capacity is 95% or more of the display capacity.
* 2 The phase balance between power supply voltages should be within ± 3%.
* 3 Maximum operating current within the operating range.
* 4 When the load is stable, it indicates that the state within the current load of ± 10% continues (except when the capacity control solenoid valve opens and closes). Setting change can be set by parameter F15 (initial value: high accuracy).
* 5 Driving sound is the front 1 m, height 1 m value.
* 6 Built-in overload protection combined type earth leakage breaker as standard.
Note 1) Please attach the attached Y type strainer (40 mesh) to the liquid inlet piping.
Note 2) For the liquid (cold water) used in this machine, fresh water and industrial ethylene glycol aqueous solution with a concentration of 30 to 40% are recommended.
However, when using an industrial ethylene glycol aqueous solution of 30 to 40%,
please note that the cooling capacity drops by about 10% .
Also, in the case of pure water, please set the electric conductivity to 1 ?S / cm or more.
Note 3) Apparatus exhaust heat quantity (kW) is about 1.3 times the cooling capacity. (Limited to air cooling)
