1. discharge pipes may be increased or decreased at pump nozzle to suit pump capacity and particular conditions of installation Use eccentric reducers on suction connection with flat side uppermost Layout the suction line with a continual rise towards the pump without high points thus eliminating possibility of air pockets that may prevent the pump from operating effectively A strainer of three or four times the area of the suction pipe installed in the suction line will prevent the entrance of foreign materials into the pump 3 6 5 mm diameter perforations in the strainer is typical INSTALLATION amp OPERATING INSTRUCTIONS Vertical In Line pumps Commercial pumps Series 4300 4360 and 4380 8 In open systems test suction line for air leaks before starting this becomes essential with long suction line or static lift Install at the pump suction a straight pipe of a length equivalent to 4 or 6 times its diameter this becomes essential when handling liquids above 120 F 49 C Armstrong suction guides may be used in place of the straight pipe run and in line strainer Install an isolation valve in both suction and discharge lines on flooded suction application these valves are used primarily to isolate the pump for inspection or repair Install a non slam non return check valve in discharge line between pump and isolation valve to protect pump from excessive back pressure and to prevent water running back through t2. equipment ATTENTION FIG 1 Noise levels ODP TEFC FRAME DESIGNATION hp dB A 59 O75 d l3 180 12 61 1 5252 61 Seu 210 3 09 66 Deus 65 7 510 250 7 5 10 70 1a 10 69 1520 280 15 20 5 15 20 74 25 30 320 2530 77 25 30 Lf 40 50 360 40 50 80 40 50 80 60 75 400 60 75 82 60 75 84 100 125 440 100 125 85 100 175 66 150 200 1 1 INSTRUCTIONS FOR SAFE USE No installation of this equipment should take place AN unless this document has been studied and under stood Handling transportation and installation of this equipment should only be undertaken by trained personnel with proper use of lifting equipment See later diagrams for lift ing advice Refer to the pump nameplate for pump speed pres sure and temperature limitations The limits stated must not be exceeded without written permission from Armstrong 1 2 TEMPERATURE Where under normal operating conditions the limit of 68 C 155 F restricted zone for normal touch or 80 C 176 F unrestricted zone for unintentional touch may be experi enced steps should be taken to minimize contact or warn operators users that normal operating conditions will be exceeded In certain cases where the temperature of the pumped liquid exceeds the above stated temperature levels pump casing temperatures may exceed 100 C 212 F and not withstanding pump insulation techniques appropriate mea sures must be taken to minimize risk for ope
