During the winter, water inside the sprinkler can freeze, creating the risk of spray damage. If the outdoor air
temperature becomes 0°C or less, use one of the following two methods to drain water from the sprinkler.
[Drain all at once from module controller] * Group must be stopped
(1) Set the operation of the heat pump to Stop.
To stop using the module controller, switch to "Stop" in the MC operation change screen.
(2) Set the module controller to Unit.
In the Remote change screen of the module controller, switch to "Unit".
(3) Close the gate valves of the water supply main pipe for the spray and stop water supply to each
module.
(4) Fully open the manual flow rate adjustment valve of the sprinkler inlet.

(5) Set the solenoid valve for the spray to ON (open).
From the operation screen, select "Main screen →Service →MC func →MC mainte →Fan and Spray check",
and set the spray of "System A (or B)" to ON.
(6) When water of all modules are completely drained, set the solenoid valve for the spray to OFF
(close).
(5) Set to ON (open).
(6) Set to OFF (close).
This method can only drain water from the spray inside each module.
As shown in "Pipe example", water drain valves (procured locally) also need to be provided in the
collecting pipe to each module. Be sure to use these valves to drain water.

[When draining separately with unit controller of each module] *Stopping by each module is possible
(1) Touch REMOTE in the power control box of the module to drain, set it to Unit (REMOTE lamp off),
and touch STOP to stop the module.
(2) Close the gate valves of the main pipe and stop water supply to the module.
(3) Fully open the manual flow rate adjustment valve of the spray inlet.
(4) Use UP or DOWN of the unit controller to select "E.COdE", and touch ENTER.
(5) Use UP or DOWN to select SPry, and touch ENTER to enter the manual mode of the solenoid
valve for the spray.
(6) Use UP or DOWN to select On (open), and touch ENTER.
* In the manual mode, use UP or DOWN to select Ctrl (automatic), On (open), or OFF (close), and touch ENTER to confirm.
(7) When water is completely drained, select Ctrl (automatic) and touch ENTER. Then touch BACK
to exit the manual mode.
(8) Perform the same procedure to drain water from the other modules.
