WARNING
Be sure to switch off all power supply before performing each of
the below checkings. Before obtaining access to terminals, all
supply circuits must be disconnected.
CHECK WATER PRESSURE
Water pressure should not lower than 0.05 MPa (with inspects the
Water Pressure Gauge d). If necessary add tap water into Tank
Unit. Refer to Tank unit installation instruction for details on how to
add water.
CHECK PRESSURE RELIEF VALVE c
•
Check for correct operation of Pressure Relief Valve c by turning
on the lever to become horizontal.
•
If you do not hear a clacking sound (due to water drainage), contact
your local authorized dealer.
•
Push down the lever after fi nish checking.
•
In case the water keeps drained out from the unit, switch off the

EXPANSION VESSEL b PRE PRESSURE CHECKING
[Lower limit water volume of the system]
Please ensure the capacity of the circulating water of the total
system including the capacity of the indoor unit is more than 30 L.
If the water capacity is insuffi cient, during deice operation, the water
temperature is lowered and the water will freeze in the system's
component leading to product failure.
