5. Operation
WARNING: Always make sure the voltage on the pump data plate matches the
installation voltage before plugging the pump into a wall outlet or hooking up to
an electrical supply. If you are unsure, have a licensed electrician inspect and
install your pump.
5.1. Fixed and Adjustable Speed Pumps
CAUTION: Before plugging your pump into a wall outlet, take a moment and
locate the control panel of your pump. The control panel is located on top of the
pump underneath a removable clear polycarbonate rain guard. A simple thumb
screw secures the rain guard to the pump; its removal allows access to the
control panel. Both fixed and adjustable speed pumps are equipped with a 3-
position rocker switch mounted in the center of the control panel. Verify the
switch in is the neutral or off-position before plugging your pump into a wall
receptacle. (see Figure 6) Note that the image shown is for the Adjustable pump,
the Fixed-Speed pump comes with the 3-way rocker switch, only.
As previously mentioned, the rocker switch has three positions. The off-position
is the middle or neutral position of the switch. The switch also provides a
momentary-on function. By depressing and holding the switch toward the pump
head (100%), the pump becomes energized. Upon releasing the switch, the
rocker returns to the neutral, or off-position and pump operation ceases. This
function is very useful when priming and/or replacing worn tubing in the pump.
To turn the pump on, depress the rocker switch away from the pump head
(switch position “|”). The switch locks in place and the pump becomes energized
– see Figure 6 for specific functions. To turn the pump off (switch position “O”),
return the rocker switch to the middle or neutral position.
5.2. Adjustable Rate Pumps
If you purchased a pump with the adjustable feed-rate option, the control panel
on your pump includes a control knob that adjusts the pump on/off cycle time.
Rates are infinitely adjustable from 5% to 100% -- see Figure 6 for an illustration.
CAUTION: DO NOT USE THE CONTROL KNOB SET TO 0% TO TURN THE
PUMP OFF: ALWAYS TURN THE PUMP OFF AT THE ROCKER SWITCH.
