Setting and Operating the Timer Control
and Starting the Pump
NOTE: Before the circulator is started, the system must
be filled with liquid and vented.
1. Set the timer switch to the actual time by turning the
programming ring in the direction of the arrow until
the timing arrow points to the actual time on the ring.
2. Switch on the power supply to the circulator and set
the manual switch to the “ON” position. The circula-
tor will now start.
3. Set the required “ON”/”OFF” times on the program-
ming ring by pushing the programming tabs either
away from or toward the center of the ring. Tabs
pushed away from the center indicate the circulator
is switched ”ON” while tabs pushed toward the cen-
ter indicate the circulator is switched “OFF”.
4. Set the manual switch to the “TIMER” position. The
circulator will now start/stop according to the settings
of the programming tabs.
8. Failure to Operate
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 indicator plug 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
7a). 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.
5. 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.
6. 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.
