Fitting Instructions - MARTINDALE M26/400 Bedienungsanleitung

Facial hair or spectacles with side arms that pass underneath the face seal will affect the sealing of the face mask.
This is likely to cause leakage and seriously impair the performance of the system. Contact Centurion Martindale for
information on suitable spectacles that can be used on the system.
Both the Unpowered and Turbine powered systems provide the wearer with air from a source remote from the immediately
contaminated area. The quality of the supplied air is dependent upon the quality of the air at this source. The user must ensure
the purity of the air supply at all times.
At very high work rates the pressure in the mask may become negative at peak inhalation.
The unpowered system (M26/400 and M26/450) can be used in a potentially flammable atmosphere.
The powered system (M26/500, M26/500/EURO) may also be used in a potentially flammable atmosphere provided the mini
turbine unit itself is not sited within or close to this flammable atmosphere.
The Mini-Turbine is NOT intrinsically safe.
REINFORCED HOSE
It is possible to join two reinforced hoses together if required using an M26A adaptor providing the limitations below are
followed.

Only the approved Martindale M26A adaptor must be used. It should be checked for damage before use.

You should join a maximum of two hoses together. (I.e. Only one M26A may be used per user's system).

The maximum total length of joined hose assembly is 20 metres for unpowered and 40 metres for powered systems.

Check that the O-rings are in place on the nipples on the hose before attaching the adaptor. The adaptor must be tightly
screwed into the ends of the hose to be joined so that nuts on the end of the hose are tight and it should not be possible for
the hoses to rotate.
Firstly fit the strainer to one end of the reinforced hose by screwing it in tightly by hand. Then stake, hook or tie the strainer in
a location/position where the air is of breathable quality (and will remain so through the intended period of use of the
apparatus). See diagram 1. Breathing quality air is defined in EN 132.
Ensure that the hose is free from bends or kinks which could impede air flow and that it is located/identified to
secure/protect it from being crushed by motorised vehicles.
Position the turbine in a dry area where the air is of breathable quality (and will remain so through the intended period of use of
the apparatus). Breathing quality air is defined in EN 132. Connect the power supply to the turbine and remove the blanking
cap from one of the turbine outlets. Ensure that the power supplied to the turbine is within the range printed on the turbine.
Turn on the power and switch the turbine on. Check that the turbine is operating and that air is being blown from the outlet on
the turbine. Connect one end of the reinforced hose to the outlet by screwing on tightly by hand; it should not be possible for
the hose to rotate once the nut is tightened. (For twin users repeat previous steps using second outlet for the second user).
Note:
if there is only one user the holed blanking cap MUST be fitted to the other outlet.
If the unit fails to start the Mains Voltage may be low - turn the turbine off, turn the air control to maximum and turn the unit
on again, allow unit to warm up for 5 minutes. Adjust airflow to required level. If the unit still fails to start refer to "Electrical
Safety" section on Page 3.
Ensure that the turbine/hose is free from bends or kinks which could impede air flow and that it is located/identified to
secure/protect it from being crushed by motorised vehicles.
Remove any protective caps from the belt bracket.
Connect the free end of the reinforced hose to the fine thread connector of the belt bracket by screwing the nut onto the belt
bracket connector tightly by HAND; it should not be possible for the hose to rotate once the nut is tightened. Connect the Y
piece of the twin air hose into the top of the belt bracket, screwing down the retaining nut tightly by HAND; it
should not be possible for the Y piece to rotate once the nut is tightened.
Fit the belt and bracket around the waist, adjusting the belt to fit the user, and snap the belt buckle together. The belt should be
tightened so that the belt bracket and comfort pad sit flat against the lower back. The belt bracket should lie behind the user
with the main air supply hose pointing down and outwards.
