[1] Initial Operation

1. Make sure the Run/Stop switch that controls the unit on the local control panel is switched off.
2. Switch on the main power.
3. Leave the main power switched on for at least 12 hours before turning on the Run/Stop switch that controls the
unit on the on-site control panel to warm up the compressor. (The compressor will not be warmed up if initial
settings have not been made. Make sure to make initial settings.)

To start an operation
Switch on the Run/Stop switch that controls the unit on the local control panel, or press the ON/OFF button on the
remote controller. (*1)
Note
The unit described in this manual features a circuit that protects the compressor from short-cycling. Once the
compressor stops, it will not start up again for up to 10 minutes. If the unit does not start when the ON/OFF switch
is turned on, leave the switch turned on for 10 minutes. The unit will automatically start up within 10 minutes.
To stop an operation
Switch off the Run/Stop switch that controls the unit on the on-site control panel, or press the ON/OFF button on
the remote controller. (*1)
(*1) Refer to the following pages for how to use the remote controller.

IMPORTANT

• Keep the main power turned on throughout the operating season, in which the unit is stopped for three days or
shorter (e.g., during the night and on weekends).
• Unless in areas where the outside temperature drops to freezing, switch off the main power when the unit will not
be operated for four days or longer. (Switch off the water circulating pump if the pump is connected to a separate
circuit.)
• When resuming operation after the main power has been turned off for a full day or longer, follow the steps under
"Initial Operation" above.
• If the main power was turned off for six days or longer, make sure that the clock on the unit is correct.
