WATER TANK DRAINING
WITH ELECTRICAL POWER
Before draining the water tanks, make sure that all manual water shut-off
valves of the lavatories and the galleys are open.
Open the three service panel doors. Remove the cap of the fill/drain port on
the water service panel. Connect the drain hoses. Put the containers in
position under each panel.
On the water service panel, turn the control handle to the DRAIN position
and pull it out to the mechanical stop.
- the FWD and aft fill/drain valves open,
- the FWD drain valve opens,
- the control lights "FWD fill/drain valve open" and "FWD drain valve open"
come on,
- water drains from the fill/drain port on the water service panel and from the
drain port on the forward drain panel.
As soon as the water level in the forward tank(s) is 5%:
- the filling line drain valve opens,
- the control light "fill line drain valve open" comes on,
- water drains from the drain port on the aft drain panel.
When the system is drained, turn the control handle on the water service
panel back to its NORMAL position.
- the FWD and aft fill/drain valves close,
- the FWD drain valve closes,
- the filling line drain valve closes,
- the control lights "FWD fill/drain valve open ", "FWD drain valve open"
and "fill line drain valve open" go off.
Note: If the outside temperature is less than 0 deg.C (32 deg. F), the valves
must stay open.
Disconnect the drain hoses. Clean and dry the service panels. Install the cap
on the fill/drain port on the water service panel. Close the doors of the service
panels. Remove all equipment and ground support.
Note: In freezing conditions, do not close the service panel doors.
