8. INTRODUCTION

Safety

The suction pumps are designed and constructed according to the safety regulations of
IEC 601-1, the EMC standard IEC 60601-1-2 and EN 10079-1. For the user's and the
patient’s safety as well as to prevent equipment damage, please observe these safety
rules:

Safety Rules

• The suction pumps MASTER/SENATOR may only be installed and operated by
competent personnel.

• Use the suction pumps with the ARDO hydrophobic bacterial filter only.

• To ensure the proper venting of the pumps, the feet must be installed on the bottom

of the pumps if used without trolley.

• Never start operating the suction pump when the housing is open (rotating parts –
hazard of injury and electric shock).

• Capacitors may be charged even if device is without power. Discharge capacitors with
discharge set!

• Check contact points of the housing for tears. If there are any tears, exchange housing.

• See that MASTER/SENATOR are set into operation according to Chapter 4 - Installation -

in the operating instructions.

• Store the service manual in a safe place, so that it is available to the trained technical
personnel at all times.

General Safety Regulations

• Never use MASTER/SENATOR in the presence of ignitable gases as anesthetic
agents. Explosion hazard!

• The suction pumps may only be opened by qualified technical personnel.
Electric shock hazard!

• Always switch the suction pump off and disconnect from mains power before
cleaning and opening. Electric shock hazard!

• Do not use solvents for cleaning. Otherwise the surface of the housing or the
synthetic material parts may be damaged.

Responsibility

ARDO is only responsible for effects on safety, reliability and performance of the device, if:

• Installation, new adjustments, alterations or repairs and maintenance works are carried
out by authorized persons.

• For repairs and replacements of spare parts use original parts by ARDO only.

• The electric installations of the respective room meet the requirements of the standards

IEC 601 and MPG (German Medicinal Products Act), and if the devices are maintained
and repaired according to this standard and to EN 10079-1.

• The pump is used in accordance with the operating instructions.

Guarantee

The suction pumps MASTER/SENATOR have a guarantee period of 2 years.

General Conditions

Maintenance

Ardo medical AG warrants for material and production faults of
the manufactured products. The guarantee period can be taken
from the respective operating instructions. Faulty material is
replaced free of charge within the guarantee period, assumed
the device was not used improperly. Wearing parts are
excluded. For ensuring guarantee and faultless functioning of
the device, the notes of the operating instructions have to be
observed. Furthermore, only original spare parts by
Ardo medical AG may be installed and/or used.

The right to guarantee is waived, when non-authorized persons
interfere with the device or alterations not conforming to the
standard IEC 601 and EN 10079-1 are carried out. There is no
right to guarantee exceeding the described scope of guarantee,
as liability to consequential damages etc.

Read operating instructions Chapter 5 - Maintenance and Care,

9. TECHNICAL DESCRIPTION AND DIAGRAMS

Mechanical Layout

The ARDO suction pumps MASTER/SENATOR work according to the principle of a piston/
cylinder system.
Both power units are based on a modular driving concept, equipped with 2 cylinder units.

MASTER 45 2 cylinder power unit (approximately 300 rpm)
SENATOR 30 2 cylinder power unit (approximately 220 rpm)

A two-stage belt transmission was developed for driving the cylinder units that may be
used for both power units (MASTER and SENATOR).

Transmission reduction for the two power units can be adjusted with the two belt pulleys
of the first reduction level (motor pinion + belt wheel = 1. level).

Ardo medical AG 5 Service Manual
MASTER/SENATOR

Subject to change

For both power units a bipolar capacitor motor with built-in temperature sensor is used.
This protects the motor coil from heating to more than 125°C.

The piston is driven over a linear unit (slide). By using this system, the piston system is
exposed to only minimal thrust forces, which ensures low wear and high service life.
In MASTER/SENATOR the pistons work in angles of 90° to each other. This ensures a
well-balanced run of the pump with low vibration levels.

Electrical Layout

The driving motor is a bipolar capacitor motor and may be used for both power units
(MASTER and SENATOR).

MASTER is equipped with a electronically controlled start-up circuit (Pushstart), so that
the power unit starts also under difficult conditions (high vacuum with simultaneous

mains undervoltage). This start-up circuit is also used in the SENATOR with 115V motor.
This circuit increases the motor torque momentarily by parallel switching in a second
start-up capacitor.
After approximately 3 seconds this second capacitor is switched off again, so that the
motor is not overloaded during continuous operation.
This start-up circuit is activated each time the motor is powered up or mains power is
interrupted.

10. MAINTENANCE

General Maintenance

It is the user’s obligation to perform a maintenance check at least once per year. If the
manufacturer performs the maintenance check, a service confirmation is placed on the
suction pump.
If you do not observe the procedures and cleaning instructions there is a danger of
contamination!

Maintenance Works for Technical Personnel

General Maintenance

Checking of

Leak Test

Check of Tubing

Safety Check

Maintenance works include the following tests:

• Checking of vacuum level, liter performance, function of
vacuum regulator

• Leak test

• Check of tubing

• Safety check (electrical and mechanical parts)

Vacuum level, liter performance, function of vacuum regulator:

There are no specifications for these checks.
The permitted tolerances are:

- vacuum level ± 5%

- liter performance ± 15%

• Connect 1 liter or 2 liter suction jar

• Pinch off the patient tubing

• Switch pump on and turn vacuum regulator to maximum

vacuum level

• When maximum vacuum level of approximately 85kPa has

been reached, switch pump off and observe vacuum meter.
After 1 minute, vacuum level should not have decreased more
than 10kPa, otherwise complete sealing is not guaranteed.

• Check tubings on cleanness* and damages.

*If an overflow has occurred, pack suction pump in a synthetic
material bag and dispose of, after clarification with the
customer.

Electrical and mechanical parts

• Check power connection on damages. Check moving power

unit parts on abrasion or damage (cylinder system, ventilator).

• According to IEC 601 and EN 10079-1, the measuring of the

leakage current (using the safety tester) has to be carried out
after maintenance or service works.

Replacing Spare Parts

Always disconnect the suction pumps MASTER/SENATOR from mains power
before opening.

Only technical personnel may replace components or repair the suction pumps MASTER/
SENATOR. Due to reasons of functional safety and testing, replacement is limited to
mechanical parts and individual electrical components. When using foreign parts or
carrying out non-authorized works on the suction pump, we refer to operating instructions
Chapter 6 - Guarantee -. Replacing components shall be carried out according to the
specification, the processes and/or the photographic illustrations. If difficulties arise,
please contact the manufacturer Ardo medical AG.

Cylinder

Dismantling

Assembly

Initial position; power unit tray is dismantled from the
housing

• Loosen the two fixing screws on the cylinder base

• Loosen mounting of the piston rods on the slide

• Slide complete cylinder with piston rod up and out

• Place cylinder from above on the cylinder holder

• Insert a 0.3 mm feeler gauge between cylinder holder

and cylinder

• Set slide to the lower dead center

• Pull piston rod all the way down (do not damage

mechanically!)

• Fix on slide with Allen screw

• Pull out feeler gauge and adjust cylinder

• Tighten both Allen screws on the cylinder foot

Assembly of the second cylinder is done analogously.

CAUTION! Glass cylinders and graphite pistons must never
be exchanged or combined with another cylinder. These two
components are specially designed for alignment.

Valves

If device is contaminated or vacuum performance is poor,
check valves on cleanness and damage.

• The valves are fixed in place by a two-component epoxy
adhesive (araldite)
