Operating and safety instructions

General remarks

The health and lives of people may depend on this tester. All persons who make decisions

regarding its use, who operate, service and maintain it or who check whether it is fully

functional must thoroughly and carefully read, understand and follow the instructions in this

operator's manual. The tester has been tested and has left the factory with all features in

perfect working order.

The information provided in this manual is subject to change without notice. Errors and

omissions excepted.

Remarks on performing tests

Do NOT use thetester for performing tests on pieces of equipment other than those mentioned

in this manual. Never apply medium pressure to a lung-governed demand valve while it is

attached to the tester’s equipment connector. Otherwise, the low-pressure gauge and/or the

lung-governed demand valve may get damaged. For more information on how to test

equipment, please refer to the relevant sections of this manual.

Operating environment

Set the tester up in a dust-free location with as little fluctuations in ambient air temperature

and humidity as possible. Avoid direct exposure to sunlight because it may have a negative

impact on the tester’s accuracy.

Malfunction and excessive strain

Whenever it is likely that the tester is no longer safe for use, make it inoperative and secure it

against any unintentional operation. A service representative of the manufacturer, or a

similarly trained and authorized person, is to diagnose and remedy the cause of malfunction.

Testing and maintenance

The tester itself needs to be tested annually to ensure that it is fully functional and leak-tight

at all pressure levels. Only original replacement parts, fitted by authorized persons, may be

used for repairs. Every 6 years, the tester is to be serviced and recalibrated by the

manufacturer. If the tester gets used a lot, it is recommended that you have it serviced and

recalibrated annually. Where there is a conflict with national provisions and requirements, the

national provisions and requirements shall prevail.

Care and cleaning

Remove dust by carefully wiping the tester's housing with a soft cloth. To get rid of more

stubborn dirt, use a soft, damp cloth and a mild cleaning solution. Never use scourers,

alkaline/acidic detergents, scouring powder or volatile solvents such as alcohol, petroleum

spirits, dilutions or insecticides for cleaning.

Storage

Store the tester at around 20 °C in a dry location that is free from dust and dirt. Keep the tester

protected from direct sunlight. If you do not use the tester for several weeks in a row, you

should remove the battery for environmental and safety reasons.

Accessories

Verify you have received all accessories included in the scope of delivery.

Introduction

Constantly increasing demands with regard to the performance and operational safety of

respiratory protective equipment call for a sustained effort to continually optimize equipment

testers.

Combining pinpoint accuracy with utmost operator friendliness and a stylish design, the Menzl

“Multitest plus” tester meets all the requirements of state-of-the-art equipment testing.

The tester

The “Multitest plus” tester is suitable for testing respiratory protective masks, lung-governed

demand valves and pressure reducers at low pressure and medium pressure. In its basic

configuration, it can be used for performing tests on pieces of equipment with round-thread

connectors and euro couplings. Thanks to a wide range of adapters (see accessories), it is

also possible to test equipment with other types of connectors as well as different makes of

chemical protective suits.

Features of the tester

One battery (type D cell) is required for operating the tester. A compressed-air supply is not

needed. Optionally, the tester can be powered via a 230V/1.5V mains adapter. The low

pressure for leak-tightness tests and functional tests is provided by the tester's built-in pump

and shown on the low-pressure gauge. The static SCBA medium pressure is supplied to the

tester by means of the medium-pressure connector and shown on the medium-pressure

gauge. Chemical protective suits get inflated via the filling hose's push-button valve, which

features a plug-in nipple that is compatible with the plug-in safety coupling. The dummy head

can be inflated with compressed air from either an SCBA or a compressed-air supply line.

Scope of possible tests

- all leak-tightness tests, opening-pressure tests and closing-pressure tests

- all tests performed at low pressure or medium pressure

- all tests done with a suction pump or a pressure pump

Performing tests

For the time intervals against which leak-tightness tests and functional tests are to be carried

out, refer tothe manual provided by the equipment manufacturer. Always perform tests against

the specifications found in the relevant equipment manual.

Important note on performing tests

Do NOT apply medium pressure to the lung-governed demand valve while it is attached to

the equipment connector.

Be sure to strictly adhere to the following sequence of steps in order to prevent the tester and the

lung-governed demand valve from being damaged:

- Detach the lung-governed demand valve from the equipment connector.

- Apply medium pressure to the lung-governed demand valve.

- Attach the pressurized lung-governed demand valve to the equipment connector.

Normal-pressure equipment

Lung-governed demand valve without positive medium-pressure

Let the pressure build up until it is slightly higher than the level required

for testing and move the “pressure pump” lever to the “CLOSED”

position.

Release the pump push-button.

Release pressure via the relief valve until the level required for testing is

reached.

Perform the test against the specifications provided by the equipment

manufacturer.
