Section 02810 <br />Irrigation <br />the length of the control wire. Where it is necessary to run control wire in a <br />separate trench, the wire shall be encased in a PVC sleeve and have a <br />minimum cover of 12". <br />2 All wire connections at remote control valves and at all wire splices, the <br />wire shall be left with sufficient "slack" (minimum 12" coil) so that in case of <br />repair the valve bonnet or splice may be brought to the surface without <br />disconnecting the wires. All splicing of wire shall take place in valve boxes. <br />All splicing of wires shall be made by using UL listed waterproof wire <br />connectors as recommended by the wire manufacturer. <br />3 Each remote control valve or group of remote control valves, which is to be <br />connected to one station of a controller, shall have wire sizes as <br />recommended by the manufacturer. All remote control valves, which are to <br />be connected to the same controller, shall be connected to a common <br />ground wire of a size as recommended by the manufacturer. <br />4 Provide a 10" expansion coil at each valve to which controls are connected <br />and at 100' intervals. <br />5 Connection of wires from multiple valves operating from one controller <br />circuit shall take place at the controller location. A wire shall be installed <br />from the controller to each valve in the system. <br />6 Provide 2 extra control wires from the controller to the furthest zones <br />including the zones where the main line ends. <br />7 Utilize different color control lines for each controller. White will be used for <br />all common wires. A separate common is to be used for each controller. <br />The wire color should also be varied for the spare control wires. All pairing <br />of control lines shall be made at the controller. <br />3.12 Controller: <br />The controller shall be installed following the recommendations of the <br />manufacturer of equipment. The location of the controller shall be <br />approved by the Landscape Architect and/or his authorized representative <br />before actual installation of the controller. <br />2 Controller shall be hard wired to a waterproof toggle switch provided within <br />5' of the controller. <br />3.12 Control valves: Electric remote control valves shall be installed as indicated on the <br />drawings and according to manufacturer's recommendations. The flow control <br />stem on all remote control zone valves shall be adjusted downward to minimize <br />any over pressurization before any individual nozzle adjustments on the sprinklers <br />are performed. <br />3.12 Testing, Balancing and Adjustments: <br />02810-9 <br />Irrigation <br />State Road 60 and 43rd Avenue <br />
