pump controls in such a way that if either device operates , the pump will shut down . The <br /> devices shall be self-resetting. The cable shall be fixed to the pump using a watertight <br /> trumpet assembly. The pump shall be capable of running continuously in a totally dry <br /> condition under full load, without damage, for extended periods . Before final acceptance, a <br /> field running test demonstrating this ability , with four (4) hours of continuous operation <br /> (water supplied by the contractor) under the above conditions , shall be performed for all <br /> pumps being supplied, if required by the IRCDUS . Pump motor cables shall be suitable for <br /> submersible pump applications and shall be properly sealed. <br /> B . Power cables shall be sized according to NEC standards and shall be of sufficient length to <br /> reach the control panel without splicing. The cable shall be oil resistant and capable of <br /> continuous submerged operation in raw sewage. The pump cable entry shall provide strain <br /> relief for the cable. The cable and entry into the pump shall be "Factory Mutual" approved <br /> for use in NEC Class 1 , Division 1 , Groups C and D hazardous locations . <br /> C . Lifting cables shall be provided for each pump . Each pump shall be fitted with a braided, 316 <br /> stainless steel lifting cable of adequate strength, and shall be five (5 ) feet longer than wet well <br /> depth to control panel to permit raising the pump for inspection and removal . <br /> 2 . 04 PUMP GUIDE RAILS & BRACKETS <br /> A. A guide rail base for sliding pump mount shall be an integral part of the pumping unit, and <br /> the pump casing shall have a machined connecting flange to connect with the cast iron guide <br /> rail base. The base shall be bolted to a stainless steel base plate affixed to the wet well bottom <br /> with stainless steel anchor bolts and so designed as to receive the pump connection without <br /> the need of any bolts or nuts . Sealing of the pumping units to the guide rail base shall be <br /> accomplished by a simple linear downward motion of the pump with the entire weight of the <br /> pumping unit guided by stainless steel guide tubes or T-bars which will press it tightly <br /> against the discharge connection or a single stainless steel guide with a locking guide rail <br /> base as approved by the Engineer. No portion of the pump shall bear directly on the floor of <br /> the sump and no rotary motion of the pump shall be required for sealing . The guide rail base <br /> shall have a 4-inch discharge elbow which shall be totally supported by the pump mount. <br /> 2 ,05 PUMP CONTROL SYSTEM <br /> n <br /> A. General <br /> 1 . A pump controller shall be provided for the wastewater pumping station . The <br /> controller shall respond to the liquid level switches to automatically start and stop <br /> pumps in response to liquid level in the wet well . <br /> I I j <br /> 2 . The pump controller shall be the standard system of the manufacturer as modified for <br /> this application . The wet well levels to be used in operation are as shown on the <br /> Drawings . <br /> 3 . All components within the pump control system shall be designed and sized to handle <br /> their maximum potential full load amperage and ground fault capacities . <br /> 4 . All electrical installations shall be conducted in accordance with the National Electric <br /> Code and all applicable local codes . <br /> 51 Prior to ordering electrical components the Contractor shall contact Florida, Power <br /> and Light to confirm the electric service and ground fault currents .
