*1 Under the following conditions: Chilled water temp.: 20 °C, Ambient temp.: 32 °C, Max. discharge pump circulating load. Cooling capacity is at least 95 % of listed figures. Heating capacity will change according to operating conditions.
*2 Source voltage phase unbalance should be less than ±3 %.
*3 The figure noted is when the equipment is operating at the highest capacity of its normal operating range.
*4 When the current load is continuously within ±10 %, and the ambient temperature is stable. However does not include starting times or when the heat-load exceeds the chiller capacity.
*5 Comes standard with a built-in overload protection circuit breaker (NFB).
*6 Operating noise levels are from a position of 1 m in front of the product and at a height of 1 m.

Note 1) Liquid (chilled water) that can be used are either clean water and a 30 to 40 % ethylene glycol solution. Note that there will be a drop in cooling capacity of 10 % if using a 30 to 40 % ethylene glycol solution. Alternatively, if deionized water is to be used, it should have an electrical conductivity of at least 1 μs/cm.
Note 2) Heat output from the unit (in kW) is approx. 1.3 times that of the cooling capacity.
Note 3) Depending on the operating environment, condensation may form on piping inside the product, and temporary leakage of water from the pump mechanical seals may also occur, therefore a drain pan should be installed if required.
