Range for continuous operation
Range for operation
Range for pull down operation
Range for warming up operation
• Operation range of water volume is
50-150L/min
•
The unit is designed for the following operation range:
Water temperature: 20-35°C
Water volume: 60 L/minute or more
• During cooling operation when the outside temperature is very
low, it is possible that the thermostat switches off automatically in
order to protect the unit from freezing.
• Hold ambient temperature at 0-40°C
Heat-release from the unit: 0.71 kW/10Hp/hour.
It is therefore recommended to always ventilate the room.
2-3 Standard supplied accessories
• Make sure that the following accessories are included.
(Check by removing the front panel.)

SELECTION OF LOCATION
This unit does not have specifications for outdoor installation.
The unit must be installed indoors (example: machine room, …)
Always install it in a room.
(machine room, etc.)
Paying attention to the conditions mentioned below, select the place
for installation with a prior approval of customer.
1.
The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.
2.
Consider the space required for refrigerant piping work when
installing. Refer to [Necessary Space].
3.
There is no danger of fire due to leakage of inflammable gas.
4.
The piping length between the outside unit and the indoor unit
may not exceed the allowable piping length. “

5.
Locations where the noise of the unit operating will not disturb
nearby houses, etc.
6.
Locations with airflow and ventilation holes capable of dissipating
heat from the machine and where the ambient temperature
around the outside unit is between 0 and 40°C and the humidity
does not exceed 80%.
[Necessary Space]
When installing, secure the space mentioned below without fail.
