M. Grounding provisions shall be in the main terminal box. 2.03 STRAINER CONTROLS A. General: The strainer controls shall consist of a single NEMA 4X FRP enclosure

incorporating the activation of the rotating drum motor and the motorized backwash ball valve. Modes of operation shall be manual for backwash activation regardless of operating time or differential pressure and automatic for backwash cycle activation based on operating time with a differential pressure switch providing a back-up to activate the backwash cycle anytime differential pressure increases three (3) PSID over the clean differential pressure.

B. Control Enclosure: The control enclosure shall be of FRP construction and rated

NEMA 4X for outdoor installation. C. Rotating Drum Motor Control: The strainer controls shall start and stop the

rotating drum motor via an interlock signal from the vertical turbine pump controls. A suitably sized NEMA rated combination starter with overloads shall be provided.

D. Control Power Transformer: The strainer control panel shall be equipped with a

control power transformer sized to provide the required 115/1/60 control power for operation of the strainer controls and backwash valve operation. The transformer shall be fused on the primary and secondary sides.

E. Strainer Differential Pressure Switch: The strainer backwash cycle shall be

activated by a differential pressure switch with a field adjustable set point initially set at three (3) PSID above normal “clean” condition differential pressure . The differential pressure switch shall activate the backwash control ball valve on reaching the setpoint and deactivate the control valve once differential pressure returns to normal indicating a clean strainer. The differential pressure switch shall be fitted with a NEMA 4X housing with contacts rated for the 115/1/60 power required to activate the control valve.

15521-5

F. Backwash Timer: The backwash timer shall be field adjustable with a range of 0-

100 hours. The timer shall activate the backwash valve control valve with an initial cycle setting of thirty (3) minutes with an activation time of two (2) minutes.

G. Backwash Valve: The backwash control valve shall consist of a two (2) inch

actuated ball valve with brass body, 316 stainless steel ball and stem and PTFE body seal. The valve actuator shall be housed in a NEMA 4X rated PVC composite enclosure and shall be rated for 600 in/lb.

H. Main Disconnect: The automatic strainer control panel shall be provided with a

main disconnect with lockable thru-door operator and fused output. I. Selector Switches: The automatic strainer control panel shall have an

Automatic/Manual/Off selector switch to select the mode of operaton and an Open/Closed selector switch to control activation of the backwash valve when in the manual mode of operation.

J. Pilot Lights: 22 mm pilot lights shall be mounted on the enclosure exterior for

“Strainer Running” (Red lens), “Backwash Valve Open “(Red lens) and “Backwash Valve Closed” (Green lens).

K. Push Buttons: Pushbuttons shall be provided for “Strainer Start” with a black

operator and “Strainer Stop” with a red operator. PART 3 - EXECUTION 3.01 INSTALLATION Equipment shall be installed in strict accordance with written instructions of manufacturer. 3.02 FACTORY START-UP SERVICES A. A factory trained service representative shall be made available for start-up
