Pump Solutions Group Neptune Series 600 dia-PUMP MODELS 610 thru 647 - Manual (Page 11)

5.0 INSTALLATION OUTDOORS
The “dia-PUMP” is a totally enclosed pump which can be used outdoors or indoors. When installed outdoors, make
sure that the pump is protected against extremes of nature as follows:
5.0.1 Running of the pump when exposed to tropical sunshine with ambient temperature above 90° F (32°C)
would cause excessive oil motor temperatures. The pump should be shaded and located in such a way
as to permit an ample degree of air circulation.
5.0.2 Under cold conditions, the pump should be insulated and a heater should be supplied in order to
maintain the hydraulic fluid at an ambient temperature above 30°F (-1°C).
6.0 START UP PROCEDURE
The following start up procedure is complete and does repeat instructions on filling the gearbox and pump.
6.0.1 Remove backpressure spring (anti-siphon spring) for start up. Reinstall after pump is operational if
needed.
6.0.2 Flooded Suction: Refer to Section II, Paragraph 1.0.9, for instructions on filling gearbox with hydraulic
fluid.
6.0.3 After having let pump stand for 30 minutes and having rechecked fluid level, set pump capacity indicator
at approximately 30%. Be certain that pump suction and discharge lines are open.
6.0.4 Make certain that pumping chamber is flooded by loosening vent plug (FIG. #1412 for Models 610 &
615, FIG #2314 for Models 620 & 625, FIG. #3214 for Models 635 & 637) and allowing solution to
appear. Then tighten discharge vent plug. This procedure will also allow air to vent from pumping
chamber. The “dia-PUMP” WILL NOT FUNCTION IF AIR IS TRAPPED IN THE HYDRAULIC FLUID
OR LIQUID PUMP CHAMBERS. Start pump.
6.0.5 On initial start-ups: Check for proper motor rotation (Refer to Paragraph 1.0.9). Run the pump for 10-20
seconds, then stop for 20-30 seconds. Repeat approximately 15 items in order to fill the diaphragm oil
cavity. During these short runs, listen for any abnormal motor or crank noises, and if present, refer to
trouble shooting chart.
WARNING
BEWARE APPLICATIONS WHERE WATER IS NOT COMPLETE WITH CHEMICAL TO BE PUMPED.
EXAMPLE: NEVER FORCE PRIME WHEN PUMPING ACID OR OIL BASED PRODUCTS.
