25 The Ventilator must be connected to a suitably
rated and grounded electrical power source. The
ventilator must not be started or used on battery
power alone.
26 The ventilator must have its batteries charged
every 14 days. The ventilator must be connected
to a mains power source for 24 hours to ensure a
full charge. Failure to charge the batteries will
shorten the service life of the batteries which will
result in reduced battery life in a mains power fail
situation.
27 The ventilator can operate on battery power in
the event of mains power failure for a maximum
of 45-60 minutes (If battery fully charged at start
of mains power failure). Whilst on battery power
an alternative form of ventilation should be made
ready if the mains power supply cannot be
restored.
28 If the ventilator is operating on battery power and
allowed to completely discharge the battery, it
should be recharged as soon as possible. This is
to avoid damaging the batteries by allowing them
to remain in a deep discharged state for any
period of time. Allowing the batteries to remain in
the deep discharged state will shorten the life of
the batteries and the amount of time the
ventilator can remain on battery power.
29 If the ventilator is not going to be used for a
period in excess of 40 days then disconnect the
batteries from the power supply. (See
“Suspension of the “Main Power Fail” alarm.” on
page 61).
30 If the ventilator is adversely affected by
equipment emitting electromagnetic interference
then that equipment should be switched off or
removed from the vicinity. Conversely, if the
ventilator is the source of interference to other
neighbouring equipment, it should be switched
off or taken to another location.
31 The functioning of this machine may be
adversely affected by the operation of equipment
such as high frequency surgical (diathermy)
equipment, defibrillators, mobile phones or short-
wave therapy equipment in the vicinity.
32 The equipment is not suitable for use with, or in
the presence of flammable anaesthetic mixtures.
33 The ventilator flow monitoring system is
calibrated to work in an air/oxygen mixture, the
use of other gas mixtures may affect the flow
monitoring accuracy of the ventilator.
34 Do not clean the touchscreen whilst the
ventilator is in operation.
35 Disposal of the Oxygen cell should be in
accordance with local regulations for hazardous
substances. Do not incinerate. SLE offers a cell
disposal service.
36 The ventilator contains six batteries, three
sealed lead acid batteries, two alkaline and one
PCB mounted lithium* battery. At the end of their
useful life these batteries should be disposed of
in accordance with local authority guidelines.
Note: these batteries should only be replaced by
service personnel.
* For models A & B only.
37 Apart from the batteries, the ventilator and
accessories do not contain any hazardous
components therefore no special precautions are
required for their disposal. The ventilator should
be disposed of in accordance to the local WEEE
(Waste Electrical and Electronic Equipment)
guidelines.
38 Care should be taken when attaching other
equipment as this may affect mechanical
stability.
39 There is no special protection provided against
ingress of water or liquids.
40 When using the ventilator with Nitric Oxide
therapy devices, two N4110 filters are required to
scavenge all the waste Nitric Oxide. See “Nitric
Oxide Therapy” on page 76.
41 In the event of main LCD screen failure remove
the patient as soon as possible (under clinical
supervision) from the ventilator to an alternative
form of ventilation. The ventilator will continue to
ventilate on the set parameters whilst this is
arranged.
42 Do not use solvent based cleaning solutions to
clean the touchscreen or covers.
6.1.1.2 Humidifier / Patient Circuit
43 Use only SLE approved patient circuits. On no
account should antistatic or electrically
conductive tubing be used.
44 The humidifier used in the patient circuit must be
operated and maintained in accordance with the
manufacturer’s instructions.
45 Any water trap used in the patient circuit must be
held in the upright positions and drained
regularly before it is full.
46 The patient circuit should not be modified.
Modified patient circuits or circuits with additional
sections or components may produce too high a
circuit resistance and circuit compliance for
effective ventilation.
