• Remove the transport safety lock before

the compressor is used. Place it in the

transport safety lock holder.

• After unpacking the compressor, carry out

a function check.

• Pressure data for the Compressor Mini is

given in psi or kPa.

1 psi = 6,895 kPa

1 kPa = approx. 10 cm H2O

100 kPa = 1 bar ~ 1 atm ~ 1 kgf/cm2

(kp/cm2)

• In addition to the Important information

here, always follow local and national

regulations.

• The central compressed air supply, when

connected to Compressor Mini, must not

exceed a pressure of 94 psi (650 kPa/6.5

bar).

1. Before use

Connection

• The function check must always be carried

out before the unit is put into use, or once

a week when the unit is in continuous use.

• Make sure the mains power and gas fulfill

requirements for medical equipment.

• The Compressor Mini must only be

connected to a grounded outlet.

Operation

• When in use, the compressor must be

placed so that the air vents at the back and

on the underside are not covered.

• When in use, the drainage bottle must be

checked regularly.

• If the temperature alarm or the pressure

alarm is activated during operation, make

sure that a fully operational compressor is

connected as soon as possible.

Cleaning

The unit should be cleaned at least every 200

hours of operation or once a week when in

continuous use. If the compressor is used in

a dusty environment the dust filters must be

cleaned daily.

Service

• Service and repair must be carried out at

regular intervals by MAQUET-authorized

service personnel as follows:

5 000 hour preventive maintenance-

- 10 000 hour preventive maintenance

• Only original parts from MAQUET must be

used in the compressor.

Intended use

The intended use of the Compressor Mini is

to supply dry, filtered, compressed air for a

medical respiratory ventilator or anesthesia

machine that is compatible with the

specifications of the Compressor Mini. Its

capacity is approx. 30 l/min at 50 – 64 psi (350

– 450 kPa/3.5 – 4.5 bar).

Intended user

The Compressor Mini may be used only by

health care providers who have sufficient

training and experience.

1. Before use

Caution

• The Compressor Mini has been designed

and tested to comply with requirements

specified in electromagnetic compatibility

standard EN 60601-1-2. It is the

responsibility of the user to take necessary

measures to ensure that the EMC

environment in which the system will be

used is compatible with the requirements

of EN 60601-1-2. If limits are exceeded,

this may impair the safety of the system.

Such measures should include, but are not

limited to:

normal precautions with regard to

relative humidity and conductive

characteristics of clothing in order to

minimize the build-up of electrostatic

charges

-

- restricted use of cellular phones.

• This compressor can provide only limited

flow of compressed air (30 l/min), and the

compressed air will not be dried to the

same standard as compressed medical air.

The water content and the limited air flow

may adversely affect the operation of, or

may damage, certain ventilators or other

equipment. Verify that the equipment to be

supplied by this compressor is compatible.

• Do not direct the flow of compressed air

towards the eyes or other unprotected parts

of the body.

• Federal law restricts this device to sale by

or on the order of a physician.

Description

The Compressor Mini can be placed on a

ventilator cart to form a compact unit that is

easy to move. Since the compressor runs very

quietly, it can be used at bedside with a

minimum of disturbance.

The Compressor Mini is fitted with three

alarms:

- a temperature alarm that is activated if the

compressor overheats,

- a pressure alarm that is activated if the air

pressure drops or increases, outside the

specified ranges,

- a power failure alarm.

A high pitched audible alarm is heard, together

with an LED indication and a text displayed.

The Compressor Mini is equipped with a

Standby function. In Standby mode, the

compressor will start to deliver compressed

air to the ventilator if the central compressed

air supply fails. The compressor stops

automatically when the central air supply

returns.

Compressed air

When the Standby function is required, air

from the central compressed air supply is

connected to the inlet.

The compressed air hose to the ventilator is

connected to the compressed air outlet

Drainage bottle

There is a water separator in the compressor.

It is automatically emptied twice a minute by

a solenoid valve. The water collected in the

water separator drains into the drainage

bottle. A brief ”pssh” sound is heard each time

the solenoid valve opens. The bottle must be

checked regularly and emptied when

necessary. The higher the degree of humidity

in the ambient air, the quicker the bottle fills

Condensation drain valve

The drain valve is used to ensure that there is

no water build-up in the air reservoir by

releasing any collected condensed moisture.

If the compressor is running continuously, a

small amount of water may collect in the air

reservoir.

Preparation

KMP-032X

4 inch (10 cm)

• Place the compressor in a suitable location.

The air vent at the back of the compressor

must not be covered or blocked

Do not place the compressor near a

radiator or heating unit, since the

operating temperature might increase

and activate the temperature alarm.

-

- When the compressor is used as a

standby unit, connect the central

compressed air supply to the air inlet on

the compressor.

- Check that an empty drainage bottle is

fitted.

- MAQUET Compressor Mini mounting

kits are mandatory for both stand-alone

arrangements and for mounting on carts.

The mounting kits ensure that there is

sufficient air circulation around the

compressor.
