4.8 FREEZE PROTECTION (CONTINUED)
d. Drains will also be installed anywhere that
there is a possibility of water not draining
through the above locations.
5. Utilize the air blow-out system to clear the hose
reel of water. Close the ball valve at the hose
reel, then connect compressed air to the tting
located at the hose reel. Use compressed air to
eliminate all water trapped in the hose.
If the spray head controls use water pressure for pilot
pressure, the diaphragm cavities must be drained
through the plugs/petcocks that are installed in
the valve bonnets. At the same time, the pilot lines
should be disconnected and drained to protect the
pilot valves. All valves should be left open, and all
lines disconnected, as long as the truck will remain
idle and there is a danger of freezing. Reconnect all
lines removed, and shut all valves opened, before
placing the water truck back in service.
