Preventive Maintenance
4 Maintenance and Calibration
4.1 Introduction
The maintenance and calibration is comprised of four distinct activities:
1. Inspecting and/or replacing consumable parts
2. Adjusting individual potentiometers
3. Functional testing
4. Programming coefficients into stored memory
Consult the Preventive Maintenance chapter of this manual to determine the appropriate interval for
inspection and replacement of consumables, mechanical and electronic adjustments, testing and
programming.
Ensure that all testing materials, including gas drive, breathing circuits, test fixtures, tools and
documents are available and in good working order prior to beginning test procedures.
Testing and programming requires utilizing internal service software. A password is provided by
HEYER.
4.2 Calibration Warnings and Precautions
WARNING:
The Anesthesia Machine operates on line voltage and at high
pressure. Therefore, an electric shock hazard may exist when the instrument
covers are removed. Repair and calibration procedures should only be
preformed by qualified personnel who follow proper servicing techniques.
Warnings are given in appropriate location.
WARNING:
Possible fire hazard. Fuses (i.e., additional sockets) must only be replaced by
fuses of the same type with the same rating.
WARNING:
Possible electrical shock hazard. The machine may only be opened by HEYER
authorized service personnel.
CAUTION:
Refer to the maintenance intervals in the preventive maintenance section for
guidance on which steps are preformed when.
CAUTION:
Use surgical gloves whenever touching or disassembling valves or other
components of the patient module.
CAUTION:
Ensure that the gas supply of the machine always complies with the technical
specification.
CAUTION:
If the machine should show faults during the initial calibration or testing, the
machine should not be operated until the fault has been repaired by a qualified
service technician.
CAUTION:
After servicing, functional, compliance and leak tests must be carried out before
clinical use
CAUTION:
Failure to connect device to a grounded mains out may elevate leakage current
in excess of permissible values.
CAUTION:
During transportation of the patient module, transportation protection should be
applied to the rear to protect the diaphragm valves
