For technical reasons, the contact surface between the rotor and the
ceramic ball bearing in spherical motor pumps is very small. For this
reason, even if they have not been in operation for a long time, such as
after the summer, only a small amount of torque is required to start the
pump. Ecocirc pumps do not require (and thus do not have) a
release/vent screw.
Ecocirc pump has two standard and two auxiliary operation modes:
Constant Speed
Proportional Pressure
Automatic Air Purge
Standby
Instructions to change between operation modes:
- To change between standard operation modes (proportional pressure
and constant speed) the user shall turn the knob until the low end
position and turn the knob back to the desired setting within 5 sec.
Pump indicates mode change by switching the color of the knob LED
(proportional pressure is blue and constant speed is white). In both
cases the light is constant.
- To activate the air purge function the user shall turn the knob until the
low end position and wait at least 5 seconds before turning the knob
back to the desired setting. For air purge indication see section 9. After
air purge cycle finishes (approximately 10 minutes) the pump will return
to the previous standard operating mode.
Note: if user leaves the knob at the low end position pump will enter
standby mode after the air purge cycle finishes.
- To enter standby mode without going through the entire air purge cycle
the user shall first activate the air purge function, then, turn the knob to
=
The user can set the speed of the pump by
turning the knob into any position between
1 and 7, 7 is the fastest. The preset speed
remains constant, independently from the
flow.
=
The user can set the maximum strength of
the pump by turning the knob into any
position between 1 and 7, 7 is the
strongest. The pump automatically
decreases its speed at low flow, thus
providing energy saving.
=
The user can purge the trapped air from
the pumphouse.
=
The user can keep the power consumption
low (<1W) when pump operation is not
needed.
