Revision date: 11/05/06 

Even partial reproduction is prohibited without authorisation in writing 

 

Take all appropriate precautions when welding or 
carrying out any other repairs which release heat, 
flames or sparks. Protect all components in the 
vicinity with non-flammable material. Drain 
lubrication system parts or components containing 
oil if working close to them.  
Never use a naked flame as a light to inspect the 
drier.  
Before dismantling a drier make sure that all the 
moving and heavy parts are attached. After the 
intervention, check that no tool rag or waste has 
been left inside.  
Check the direction of rotation of the electric 
motors, and, in particular, the fan, when starting the 
machine after an intervention on the electric 
connections or the power supply cut-out.  
All protection systems must be reset after repair or 
maintenance.   
Do not clean components with flammable liquids 

when the drier is operating.  

If non-flammable chlorinated hydrocarbons are 
used for cleaning, take all safety precautions to 
prevent injury from the toxic vapours released.  
Before removing any panel or dismantling any part 
of the unit:  
1.

 

Turn off the power supply to the drier by setting 

the master switch to "OFF " and removing the fuses.  
2.

 

Stick a label on the lever of the master switch 

and install a «WORK IN PROGRESS - DO NOT 
ENERGISE " warning panel. Do not touch the master 
switch and do not try to start the drier if the warning 
panel is in place.  
3.

 

Close the by-pass valves up- and down-stream 

from the drier and install on each valve a “WORK IN 
PROGRESS - DO NOT OPEN " warning panel. Only 
reopen these valves when restarting the drier.  
4.

 

Check that all pressurised components in the 

system have reverted to atmospheric pressure. 
Check that all the pressure gauges indicate a 
pressure of zero bars, i.e. atmospheric pressure. 

2.2

 

Cooling fluid safety notice 

Mastéria dryers use a cooling gas of the type 
shown on the manufacturer's plate on the 
appliance.  
Very dirty refrigerating circuits, for example 
following a compressor fire, must only be cleaned 
by a qualified refrigeration technician. Comply 
with current safety laws and regulations.  

The refrigerant is not flammable, explosive, toxic or 
corrosive in normal conditions.  When released into 
the atmosphere, it becomes a heavier-than-air 
and almost odourless vapour.  In contact with a 
naked flame or a very hot metal surface, this 
vapour breaks down into highly irritant products 
which are immediately noticeable.  

If the refrigerant gas leaks, it is advisable to air the 
buildings concerned abundantly and to shut down 
all the systems likely to break down the vapours by 
flame or heat immediately.  
Every intervention on the cooling circuit must be 
carried out by qualified personnel approved by 
CTA.  

In the event of:   

 

chilblains, warm up the frozen skin as soon as 

possible.   

 

splashes in the eyes, rinse abundantly with 

running water.   

Then consult a doctor immediately.
