SETUP AND DRIVE OPERATION
1. Unpack the drive. Save packing material until proper product operation has
been verified.
2. Install pressure gauge, pressure regulator/lubricator/filter assembly (B, C) and
muffler (D). See Figures 1 and 2 for proper orientation. (All items and fittings
included.) Use thread seal for all connections to reduce the possibility of air
leakage.
3. Connect compressed air line to 1/4 NPT(F) connection on regulator (or use
adapter for 3/16 in ID hose provided).
4. Mount Pump Head and load tubing. (See Pump Head manual.)
5. Turn on compressed air line to start pumping (maximum: 150 psig [10.3 bar]
inlet).
6. Adjust flow rate with the adjustment knob on top of the regulator.
Vary flow rate from 1 to 25 psig (0.07 to 1.72 bar). (Lock flow rate by using
snap-action push-pull knob.)
CAUTION:
Ensure that pump speed does not exceed 600 rpm. Speeds
higher than 600 rpm may damage pump.
7. For continuous-duty or high-speed applications, use of the lubricator is
recommended. Adjust the lubricator with the adjustment knob on top.
For higher speeds, set lubricator to provide 1 to 3 drops per minute. Use a lower
setting for lower speeds. See MAINTENANCE for RECOMMENDED LUBRICANTS.
(Lock lubrication rate by using snap-action push-pull knob.)
