Installation

Hydrants should be handled with care to avoid damage. It is recommendedto keep hydrants closed until use
If the hydrant is not to be used straight away then it is recommended tocoat threads and other machined parts with anti-rust oil and the hydrantshould be stored in a dry and ventilated area. For long-term storage,thehydrant should be checked regularly
Before installation of hydrants, the connection should be free from dirt orother matter
The positioning of the hydrant should be in accordance with local requirements.ldeally the pumper should face the street and all connections should beaway from any obstruction to connecting hoses
The inlet elbow should be placed on a solid surface and if possible bracethe side opposite the incoming flow to reduce reaction stresses
The underground parts of the hydrant should be surrounded with coarsegravel for support and drainage
After the hydrant has been installed and tested, it is recommended to fullyflush the hydrant before closing for service.Before replacing the nozzlecaps, it is recommended to check for correct drainage of the hydrant onclosing of the valve: This can be achieved by placing a hand over thenozzle opening, a suction should be felt.

Operation

Unscrew the nozzle caps and connect hoses
Open the hydrant using the hydrant key (included) to the fully openposition by turning the operation nut in an anti-clockwise direction.Donot force the hydrant to open further past the fully open position.Notethat the hydrant valve is not intended to control the flow, it should beused in either the fully open or fully closed position
To control flow, a pressure/flow control valve should be fitted to the nozzleoutlets on the hydrant
To close, turn the operation nut into a clockwise direction again, do notover tighten

Material List

Carry out a visual inspection for signs of significant corrosion which may impair performance
Where possible, carry out leakage tests by opening one of the nozzle caps slghtly and then open the hydrant valveOnce the air has escaped, tighten the hose cap and check for leaks
Close hydrant and remove one nozzle cap so that the drainage can be checked

Flush the hydrant
Clean and lubricate all nozzle threadsClean the exterior of the hydrant andrepaint if required
