USE AND OPERATION
6.1.2
OXygENATOR
We recommend using Meods oxygenators.
• We recommend using Medos oxygenators.
Before connecting, check the oxygenator for damage.
Only use undamaged oxygenators. Follow the directions
in the oxygenator manual.
WARNINg
Only use oxygenators than can sustain a
water pressure of 0.15 bar.
Oxygenators can be connected or disconnected with the
unit on or off.
Disconnecting oxygenators during
operation
• In heating mode:
Reduce the target temperature before
disconnecting the oxygenator. Otherwise,
the water in the unit’s circuit will briefly
rise above the target temperature and
may trigger the alarm TEMP.DIFF > 1 °C
(depending on the time lapse).
• In cooling mode:
Increase the target temperature before
disconnecting the oxygenator. Otherwise,
the water in the unit’s circuit will briefly
fall below the target temperature and
may trigger the alarm TEMP.DIFF > 1 °C
(depending on the time lapse).

OPERATION
6.2.1
SWITCHINg ON
Fill the water tank (see „4.3.1 Filling the system with
water“ on page 12) to the MAX mark with sterile water.
Follow the instructions on disinfecting (see “7.2.2 Chang-
ing water and disinfecting the water circuit” on page 27).
• Switch on the unit using the push button (8).
The push button at the front of the unit remains
pushed in while the unit is on.
• Allow the unit to run until the air is eliminated
from the unit and the hoses. For this pupose posi-
tion the hoses level with the unit or lower.
• Check the water level on the gage (5). If necessary,
switch the unit off, disconnect the power and top
up with sterile water.
• Connect the oxygenator to the unit. Check the
water level on the gage (5), especially if you have
connected an empty oxygenator.
• The height difference between oxygenator and
unit must not exceed 75 cm.
• Reconnect the unit to the power supply, switch
it on and allow it to run for about two minutes to
remove air from the circuit.
• Check the water level on the gage (5) again. If nec-
essary, switch the unit off, disconnect the power
and top up the water.
Please note that the tank contents may
leak out if there is a fault. For this reason,
be prepared in advance to take corrective
action
