Integrated socket strip

The integrated socket strip can be used to connect — infusion pumps and — SpO

2 measuring equipment.

Connections may only be made by qualiﬁed technical staff.

Caleo does not monitor the power supply to external devices.

[ Do not exceed the maximum power input of the

connected accessories (all 4 sockets together: max. 2A). The maximum permissible total leakage current must not be exceeded. For the leakage current of Caleo® without socket strip, see "Technical Data" on page 106.

Checking readiness for operation Before using for the ﬁrst time

Checking readiness for operation

Before using for the ﬁrst time

● Check that the mains voltage supply corresponds to the

voltage rating on the nameplate (see page 125).

● Check that the altitude above sea level is correctly set

(see page 73).

Before each use

● Check that the equipment has been disinfected and

cleaned in accordance with the conditions laid down by the

hospital (see "Disinfecting/Cleaning/Sterilising" on

page 84).

● Check that an adequate gas supply is available for the

equipment to be used.

● Check that the required accessories and therapy

equipment are available and in perfect condition.

Only use parts that have been stripped down and sterilised.

Check readiness for operation in accordance with the

relevant Instructions for Use.

● Check that there are no cracks or sharp, chipped edges on

the incubator canopy.

● Check that the hinges and catches on the canopy are in

proper working order.

● Check that the cables and hoses have been routed

correctly and safely.

● If the control unit is mounted on the handle side, check that

the cable to the control unit is routed through the cable

guides on the basic pole.

● Check that there is sufficient space for adjusting the tilt and

height.

● Connect to the mains supply.

● Check that the slits of the sensor unit are not fouled.

Do not use multiple-plug adapters for the Caleo® power supply!

The patient leakage current may rise above the permitted limits if the protective earth conductor fails when equipment is connected to the socket strip. The risk of electric shocks cannot be excluded in such cases.

Before using the unit, make sure that the following tests have been performed:

Disinfect hands before each test!

Check that the hand ports are secure 1 Open hand port = press catch

● Close hand port until the catch engages.

● Pull the edge of the hand port – it must not open.

If the hand port fails to remain engaged:

● Call DrägerService.

Check that the front ﬂap is secure

● Open the front flap and fold it down (see page 18).

1 Raise and press the flap closed and turn the two knobs

outwards until they tangibly engage in the horizontal position.

Make sure that both knobs are engaged! The red latches must no longer be visible!

If the front ﬂap fails to remain engaged or if the red latches are visible:

● Call DrägerService.

Check that the side ﬂap is secure

● Open the side flap and fold it down (page 19).

2 Fold up the side flap and press it closed. Turn the two

knobs outwards until they tangibly engage in the horizontal position.

Make sure that both knobs are engaged! The red latches must no longer be visible.

If the side ﬂap fails to remain engaged or if the red latches are visible:

● Call DrägerService.

Check that the canopy is secure 3 Grasp the handle and open the canopy.

4 Lift open the flap (approx. 60o).

5 Raise the side prop.

● Lower the canopy until the prop is secured in the slot of the

canopy.

● Repeat the test on the other side.

Checking readiness for operation Before each use

1 Grasp the handles on the sides of the canopy with both

hands.

2 Lift the canopy horizontally off the pillar elements.

If the canopy holders are damaged:

● Call DrägerService.

Check that the double wall is securely in place

● All 4 retaining lugs in the canopy must be seated in the

oblong holes of the double wall.

If the double wall or the retaining lugs in the canopy are damaged:

● Call DrägerService.

Check that the trough is secure

● Remove the canopy.

● Remove the mattress.

● Remove the bed.

3 Check the catches of the trough.

● Place the bed on the trough.

● Place the mattress on the bed.

● Refit the canopy.

226 37 570

If the catches for the trough are damaged:

● Call DrägerService.

Remove the bed

● Open the front flap and fold it down.

4 Set both knobs horizontally to the position marked , 5 Grasp the bed by the recessed handle or by the knobs and

pull it out towards the front as far as it will go.

5 Push the bed back until it clicks into place, 4 turn the knobs to the position.

● Close the front flap.

If the bed cannot be pulled out or pushed in or if the knobs are damaged:

● Call DrägerService.

If the bed is not fully pushed in, the hot air duct will be interrupted, causing the control system to malfunction! The result may be excessive cooling or overheating of the patient!

Activate the self-test, check audible warning tone 1 Switch on the unit = press the on/off switch until it clicks

into position.

Checking readiness for operation

Before each use

During the self-test, the functions of the machine are checked.

The audible signal, alarm beep sequence, screen displays and LEDs must be checked by the user.

— An audible warning signal and an alarm beep sequence are

sounded.

If the warning signal or alarm beeps are not sounded,

● Call DrägerService.

— The screen and LEDs initially go dark and are then lit. If individual pixels fail to light up or screen images are burnt, or if the LEDs fail to light up,

● Call DrägerService.

— The opening screen is displayed. If the opening screen is not displayed,

● Call DrägerService.

Checking readiness for operation Before each use

Check the bed tilting mechanism 1 Tilt the bed.

During the tilting process, the entire housing of the Caleo must move uniformly. If not:

● Call DrägerService.

Do not reach in between the housing and the housing support while the unit is moving! Risk of injury!

2 Return the bed to the horizontal position (see page 23).

● The spirit levels in the bed show whether the bed is

horizontal. This check is especially important when using

the built-in weighing scales (see page 78)!

132 37 570

If the spirit levels are damaged:

● Call DrägerService.

Check the height adjustment mechanism

● Operate both foot pedals in succession to raise and lower

the Caleo® (see page 22).

● Then adjust to a comfortable working height.

When adjusting the height, the entire housing of the Caleo® must rise or descend uniformly. If not:

● Call DrägerService.

Check the power failure alarm

● Disconnect the unit from the mains.

3 The power failure LED must flash.

253 37 570

An intermittent tone must start. The volume of this tone must remain constant for at least 30 seconds.

If the volume decreases too soon:

● Leave the incubator connected to the mains and switched

on for 24 hours to recharge the NiCd battery.

● Repeat the test.

If the volume again decreases too soon:

● Call DrägerService.
