Diesel Engine driven Pump.
1.#.1
To start a diesel engine driven pump3 the operator should &e familiar &eforehand with the operation of this t"pe of e;uipment. The instruction &ook issued &u" the engine and control manufacturer should &e studied to this end.
1.#.
The storage &atteries should alwa"s &e maintained in good order to ensure prompt satisfactor" operation of this e;uipment.
1.#.#
Check electrol"te level and specific gravit"3 inspect ca&le conditions3 corrosion etc.
1.$ Fire Pump Settings 1.$.1.The fire pump s"stem3 when started &" pressure drop3 should &e arranged as follows4 1.$..The psi increments for each additional pump. In the case where a &ooster pump is &eing used3 the start point should not &e set so low that the pressure of the water suppl" feeding the pump will keep the pump from starting3 even at su&stantial flow rates. 1.$.).?here minimum run times are provided3 the pump will continue to after attaining these pressures. The final pressures should not e(ceed the pressure rating of the s"stem. 1.$.*.?here the operating differential of pressure switches does not permit settings3 the settings should &e as close as e;uipment will permit. The settings should &e esta&lished &" pressures o&served on test gauges. 5nother alternative that can &e e(plored when the operating differential of a pressure switch does not permit settings this close is to use separate3 independent switches for start and stop settings3 which will &e calculated and verified during the commissioning period.
