AUTOMATIC WATER EJECTOR.

“AUTOMATIC” WATER EJECTOR – CHALMERS PATTERN

(Hand Operated Unit Available)

USES:
Draining Cellars, excavation etc., using water propulsion

SIZES:
3/4″ and 1 1/4″ (20 & 32mm)

CONSTRUCTION:
Bronze body and Brass, Copper Floats

FIXING INSTRUCTIONS:

Size of the well required is 1’9″ wide and 2′ deep. If firmly fitted with iron pipes, other support is not normally required. Do not fix the Ejector lower down than is necessary; every foot lower may mean much extra drainage and also greater proportionate cost to elevate. Stop cocks are not normally required but may be used for convenience in fixing and regular service. Keep the well clear of refuse as owing to the strong suction n this Ejector, perforations are liable to become clogged with paper, refuse, etc. It is necessary to unscrew and clean out the suction pipe and strainer at regular intervals are required.

NOTE:
When correctly installed and adjusted the injector gives good service under normal conditions. It should be tested through several cycles after installation to ensure correct operation and should be inspected at regular intervals. It should not be installed in an unattended location where failure of operation might result in unacceptable accumulation of water.
