For continuous operation, set the manual
switch to the “ON” position. To switch the
circulator off, set the manual switch to the
“OFF” position. The “ON”/”OFF” modes may be
used without affecting the function of either the
programming ring or the timer switch.

In case of power outage the timer will not keep
time. After power has been restored, the correct
time of day must be reset by rotating the
programming ring in the direction of the arrow
until the timing arrow points to the actual time
on the ring.

•
Disconnect line cord from
system power.
•
Remove (2) timer cover
screws.
•
Gently rotate speed
selection stim to desired
speed
(see Figure 7a).
•
Re-install (2) timer cover

9. Troubleshooting
When the pump is first started, the shaft may rotate
slowly until water has fully penetrated the bearings.
If the pump does not run, the shaft can be rotated
manually. To accomplish this, switch off the electrical
supply, and close the isolation valves on each side of
the pump. Remove the large screw in the middle of the
nameplate. Insert a small flat blade screwdriver into the
end of the shaft, and gently turn until the shaft moves
freely (see Figure 8a). Replace and tighten the plug.
Open the isolation valves and wait 2 to 3 minutes for the
system pressure to equalize before starting the pump.
