 Breathing system problems (no alarm)
Symptom Problem Solution(s)
Gas scavenging flow is too low.  Suction supply problem. Use a different suction 
supply.
Filter blockage. Active 
systems have a flow 
indicator to show this.Replace the filter. Refer to 
“Disassemble the scavenging 
path” in Section2, Cleaning 
and Sterilization.
The bellows fills when the Bag/
Vent switch is set to Bag or the 
bag fills when the switch is set to 
Vent.Leak through Bag/Vent 
switch. Causes include dirt 
or damage to the o-ring.Refer to “Manifold 
maintenance” in Section 4, 
User Maintenance.
The ventilator does not read the 
position of the Bag/Vent switch. 
Use manual ventilation, if 
necessary.Ventilator or absorber 
malfunction.Ventilate manually. Ask a 
qualified service 
representative to repair the 
system.
The ventilator does not correctly 
identify the breathing circuit 
module.Broken identification tabs. Remove the module and look 
at the tabs on the rear. If there 
is damage, use a different 
module.
Dirt on the optical sensors 
that read the tabs.Use a DAMP alcohol prep to 
gently clean. Squeeze dry the 
prep before you use it.
Ventilator malfunction. Ask a qualified service 
representative to repair the 
system.
APL valve does not operate 
correctly.APL valve problem. Replace APL Valve seal and 
diaphragm - Refer to User 
Maintenance.
Bellows falls > 100 mL/min 
during bellows tests.Leak in the breathing 
system.Check/clean/reposition the 
pressure relief valve. If the 
problem persists, replace the 
pressure relief valve, bellows 
base, or bellows assembly.

If a circuit breaker opens frequently, do not use the system. Have 
an approved service representative repair the system
Symptom Problem Solution
Mains indicator is not on. The electrical power 
cable is not connected.Connect the power cable.
The inlet circuit breaker 
(toggle switch) is open.Close the circuit breaker 
(Figure 5-1).
The power cable is 
damaged.Replace the power cable.
The electrical socket the 
power cable connects to 
has no power.Use a different electrical 
socket.
An internal fuse is open. Have a service 
representative repair the 
system.
The electrical outlets do not 
have power but the mains 
indicator is on.The main outlet circuit 
breaker is open.Close the circuit breaker.
One electrical outlet does not 
have power.The outlet circuit breaker 
is open.Close the circuit breaker.
A circuit breaker opens 
frequently.Equipment connected to 
the outlet(s) uses more 
current than the circuit 
breaker rating 
(Figure 5-1).Use a different power 
supply for some of the 
equipment.
The equipment 
connected to the outlet 
has a short.Do not use the equipment 
until it is repaired.
Tec 6 has no power. Not plugged into outlet. Connect power cable.

::: :
No repair should ever be attempted by anyone not having experience in 
the repair of devices of this nature.
Symptom Problem Solution
High-pressure leak  Controls are not set correctly. Set the system switch to 
Standby and the auxiliary 
flowmeter to Off.
Equipment connected to pneumatic 
outlet.Disconnect the 
equipment.
High-pressure leak Incorrect cylinder connection (cylinder 
yokes).Make sure that there is 
only one cylinder gasket, 
the gasket is in good 
condition, and the 
T handle is tight.
Incorrect cylinder connection (DIN 
connection.)Make sure the nut is tight.
Low-pressure leak with 
a vaporizer on.The vaporizer is not correctly installed. Correctly install the 
vaporizer.
The vaporizer fill spout is loose (fill port 
type vaporizer).Tighten the fill spout.
Vaporizer port o-rings (external) are 
damaged or not installed.Install new o-rings.
A vaporizer malfunction (the leak stops if 
you use a different vaporizer in the same 
position).Send the vaporizer to a 
Datex-Ohmeda Service 
Center.
A port valve malfunction (the leak 
continues if you use a different vaporizer 
in the same manifold position). Have an approved service 
person repair the vaporizer 
manifold.
