By pressing the key ↵↵↵↵ the determined quantity is set and the pump is calibrated.
(During the pump doses it could be stopped by the key ←←←← . and the calibration process is stopped without a change).
The initial calibration should be done after at least 1 week in operation and should be done again after this time..
Experience has shown that during this period, the pump power changes. Then the pump power remains largely stable.
For new dosing pumps, additional modules rsp. pump heads please note: after initial calibration should be done a
recalibration every 4 – 6 weeks, as during this operating period, the hoses and rollers run in and the dosing quantity
may change. Thereafter, the dosing rate remains generally stable.
The dosing quantity can also vary over time as a functon of wear and pollution of the pump heads.
Regular cleaning of the pump heads and motor shafts are indispensable. See Attendance/Maintenance.

The programming of the EP-devices should otherwise be done as described above.
For programming of other additional devices of Messrs. GroTech, please see the
operating manual of the corresponding devices !
How to put the TEC 4 NG into operation:
1. Please place the TEC 4 NG close to the aquarium, below the top most water level. In order to avoid uncontrolled running
of liquids into the aquarium (in case of defect rubber hoses) that is good practice.
2. It is possible to change the direction of each of the pump heads to 90°, 180° or 270° (up, lateral and below). Therefore
please press the two clips, which are positioned left and right beneath the rubber hose outlets, pull off the pump head, turn
the pump head into the desired position and fix onto the driving shaft. Pump head is correctly installed after you heard
„click“.
3. Please connect rubber hose (rubber hose for air 4/6 millimetre) with the inlets and outlets of each pump via provided
connectors (inside of the box). Left rubber hose is pressure side and right rubber hose is suction side (to be seen if the
outlets are in below position).
Page 4
4. In order to avoid back-flow conditions (in case of defect pump rubber hoses) please make sure that the connection rubber
hoses on pressure side may not insert into the aquarium water.
5. Please insert the connection rubber hoses of the suction side into the trace-element reservoirs.
6. Please set the desired daily dosing quantity (weekly dosing quantity divided by 7) via the switches.
(Please see programming of pumps/adjustment of dosing quantity).
7. Please plug in the AC/DC-adapter (85-250 VAC/50-60 Hz).
8. Pump no. 1 starts pumping and LED begins to flash.
9. Now the rubber hoses will be deaerated.(Please see manual control of the pumps)
Attendance/Maintenance :
The TEC 4 NG is largely maintenance-free.
However, the pump cassettes of the individual dosing pumps should be dismantled every half year and the insides
of the cassettes, the rollers, the rubber hoses and the motor shaft be cleaned with a fluffy-free
cloth and some spirit.
According to the daily dosing quantity and the type of dosed liquids the cleaning intervals should be adjusted.
Under no circumstances the pumps should be oiled!
