PRECAUTIONS For Pumps with PVC & 316SS Liquid Ends WHEN USED IN SWIMMING POOLS OR SPAS / HOT TUBS (ANSI / NSF 50) Caution on Chemical Concentration: There is a potential for elevated chemical concentration during periods of no flow, for example, during backwash in the system.

SECTION 1 - GENERAL DESCRIPTION 1.4 PRODUCT CODE MacRoy G pumps are available in a variety of ® different configurations. For a breakdown of the options included in a specific pump, compare the pump model number and product code found on the pump nameplate with the model / product code breakdown shown in Figure 1.

SECTION 2 - INSTALLATION MacRoy G pumps are provided with mounting Pump Drive ® holes to accommodate anchor bolts. Refer to 1. Flood the gearbox compartment with a high Figure 3 for mounting hole dimensions. grade lubricating oil / rust preventative such as Mobile Oil Corporation product “Mobilarma 524”.
SECTION 2 - INSTALLATION To minimize viscous flow losses when handling • Use piping heavy enough to withstand maximum viscous liquids, it may be necessary to use suction pressures. piping up to four times larger than the size of • Remove burrs, sharp edges and debris from the suction connection on the pump.
SECTION 2 - INSTALLATION • When pumping a liquid near its boiling point, Suction Piping Considerations • It is preferable to have the suction of the pump provide enough suction head to prevent the liquid from “flashing” into vapor when it enters flooded by locating the liquid end below the the pump liquid end on the suction stroke.

SECTION 3 - OPERATION 3.1 INITIAL START-UP BEFORE SWITCHING FAILURE TO CHECK TORQUE POWER TO THE PUMP, TURN NONMETALLIC HEAD THE CAPACITY ADJUSTMENT KNOB TO ZERO. CHECK THAT BOLTS PRIOR TO STARTUP AND AFTER ONE WEEK OF ALL SHUT-OFF VALVES IN THE SUCTION AND DISCHARGE OPERATION MAY EXPOSE OPERATING PERSONNEL TO LINES ARE OPEN BEFORE INCREASING THE CAPACITY HAZARDOUS LIQUIDS.
Page 18
SECTION 3 - OPERATION Capacity Calibration After the first 12 hours of operation, the pump may be tested and calibrated to find the exact pump capacity under specific operating conditions. Usually, calibrating the pump at only 100, 50 and 10 percent capacity settings is enough to indicate pump performance throughout the adjustment range.
