Position aerial for base pump operations.

Aerial tower strips supply line off E4 and snubs wheel, allowing E4 to lay away to water source.

E4 positions itself for kink free deployment of front bumper LDH.

E4 starts supplying aerial tower with tank water and begins to hook up to hydrant.

Hook up 6" LDH to steamer connection and apply at least one additional gate valve.

With front intake drains in the open position, fully open the hydrant.

Move pneumatic valve to the open position, transferring water supply from tank water to hydrant water. You may then close intake drains.

Hook additional 4" line to gate valve and into side intake on E4. Open gate valve and ball intake valve to maximize pump capacity.

TIPS: Replenish E4 tank water early in anticipation of hydrant/water supply failure.
If immediate delivery of water is not necessary, open front intake pneumatic valve, then hydrant, before engaging pump.
