4.4 NOZZLE INSTALLATION
The nozzle is simply screwed onto the monitor’s exit threads.
CAUTION
The nozzle threads must match the threads of the monitor elbow in both size and type. Mismatched
or damaged threads may cause the nozzle to leak or uncouple under pressure and could cause
injury.
CAUTION
Do not connect aluminum to brass or brass to aluminum. Dissimilar metals coupled together
can cause galvanic corrosion that will freeze the threaded joint or cause complete loss of thread
engagement. If dissimilar metals must be coupled together, the eff ects of corrosion can be greatly
delayed by various coatings on the metal such as powder paint, hard anodizing, or silicone grease.

4.6 DRAINING RESIDUAL WATER
There is no drain on the EF1 RC Monitor itself. A drain valve should be installed on the piping to which the monitor is attached.
WARNING
All monitors, valves, and standpipes exposed to freezing conditions must be drained immediately
following use to prevent damage. To drain a standpipe, a drainage port must be opened
underground below the frost depth to keep water out of the standpipe until the next use.
