Attach the yellow refill hose coming from behind the tank to the
source tank fitting. Open the source tank valve. To avoid the
possible of lost refrigerant, the external source tank should be
checked for leakage around the tank valve. If leakage is found,
close the valve and keep it closed at all times
except during a
manual tank refill operation as described in Section 3.8.

Refrigerants can cause injury. Read and follow all warnings at the
beginning of this manual before operating this unit.
