Preparations For Final Check; Entering Device Data; Testing For Leaks And Checking Pressure Reading - Weinmann MEDUMAT Basic Servicing And Repair Instructions

3.2 Preparations for final check

1. Connect MEDUMAT Basic / Basic p to pressure supply 4.5 – 6 bar of cylinder system.
2. Connect respiration tube and pressure measurement tube to MEDUMAT Basic / Basic p.
3. Set MEDUMAT Basic / Basic p with switch in position No Air Mix to Freq. = 30 min
and P = 45 mbar.
max
4. Start check.

3.3 Entering device data

• Enter the device number and date of manufacture in the Test Record.

3.4 Testing for leaks and checking pressure reading

3.4.1 Testing for leaks on the inlet side
• With device switched off, apply pressure of 6 bar to inlet side and shut off outlet pressure.
• Set lever to
No Air Mix.
The pressure drop must be less than 0.2 bar/min.
Requirement:
• Set lever to
Air Mix.
The pressure drop must be less than 0.2 bar/min.
Requirement:
3.4.2 Testing for leaks in pressure measurement segment
• Apply pressure of 60 mbar to pressure measurement segment of MEDUMAT Basic / Basic p.
• During the measurement, a traction force of approx. 3 N must be applied manually to the elbow outlet.
The pressure drop must be less than 2 mbar/min.
Requirement:
3.4.3 Checking pressure reading
1. Attach T-connector with injector (WM 15359)
to pressure measurement connection
2. Connect test pressure gauge 0 - 100 mbar or
Timeter to free end of T-connector (pressure
gauge/volumetric flowmeter not supplied with
device).
3. Use injector to create a pressure of 55 mbar
as shown on the test pressure gauge.
Requirement: Respiration pressure reading must not
deviate from set value by more than ≤ ≤ ≤ ≤ 1.5 mbar.
