variable speed drives are powered by a DC gearmotor. A
specially designed electronic speed control system provides smooth
acceleration control over the entire flow range. The three position
on/off switch allows the user to maintain speed setting when unit is
turned off or reversed. This unit is designed for continuous operation at
any speed. All variable speed drives are rated for continuous duty at
25°C ambient.
Fuse: Replace with type AGC-1/2 Amp. Use AGC-1 Amp for dual head
pump.
Alternate Tubing Replacement Method for Medium and High
Variable Speed Units
With unit running at high RPM, pull old tubing out from outlet port of
pump. Install new tube by inserting into inlet port; continue feeding

" in at a time, allowing the roller assembly to push tubing until
tube extends out from outlet port. Pull tubing from outlet port until
desired tubing extension is obtained. Run unit for about one minute to
allow tube to seat properly.
Depending on pump model, tubing in use and fluid being
pumped, roller assembly may stop rotating when
speed/flow control is set at the low end range. Avoid
prolonged operation in the stalled position for longer motor
life.
