OMEGA
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.

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.
