Installation Method
5. Power Plug Connection
Check the earth leakage breaker, the refrigerator switch and the pump switch are turned "OFF", and
plug the power cord in the receptacle.
6. Insert the cooling liquid into the bath
Remove the cover of the bath, and insert the antifreezing liquid into the bath with its cooling coil hidden.
When supplying the liquid, remove the cap of the overflow on the left side surface of the bath without
fail, and prepare the pan for the bath.
With this status, turn on the pump switch, and circulate the liquid. At this time, check that the liquid
is circulated with no abnormal noise. There would be the case that the liquid is not circulated
because of the remained air in the bath. Turn on and off the pump switch for several times for
evacuating the remained air. After completing the evacuation of the remained air, the liquid might be
circulated. Even though the liquid is not circulated yet, turn off the power of the refrigerator and pump
switch immediately, check the status of the relevant devices referring to Page 24 "In the Event of
Failure…". (Keeping the operation of the device without circulating the liquid could cause the
malfunction of the circulation pump.)
After stabilizing the liquid circulation, supply the liquid up to the position where the cooling coil is
hidden with the liquid.
After supplying the liquid, turn OFF the power.
Cover the bath.
7. Connection of the overflow hose
I prepare a bat of around 3L separately, and please install it to prevent circulation liquid from
overflowing from a water tank by the afflux from the outside connection device at the time of the
shutdown.
