connectors are properly engaged.
5. Place one hand on top of the Portable directly over the fill connector
and press straight down. This will lower the Portable unit
approximately
correctly.
6. While holding the Portable unit in the fill position (Figure 12), move
the vent valve lever to the open position (90° from the normal "off"
position). This will result in a loud hissing noise.
Figure 12: Filling the Portable Unit
Do not leave the Companion Portable unattended
during the filling operation.
Note: During filling, maintain a slight downward pressure
on the unit with one hand to keep the unit steady and
maintain proper filling position. About 20 to 30 seconds into
the filling procedure, close and reopen the vent valve one or
more times to break up any ice that may begin to form
around the valve stem. This will help prevent the vent valve
from freezing open.
