PRELIMINARY CHECKS BEFORE USE
In the event of a temporary power blackout, wait a minute (normally approx. 50-sec)
before switching the machine back on, so that the electronic component has sufficient
time to be reset.
3.3
USE
Always use the machine with all safety devices correctly positioned. During normal
operations, wear suitable protective gear in compliance with the directives in force
(protective face mask, eye goggles, overalls and gloves). Do not tamper with the
machine in any way.
Pay particular attention to possible refrigerant liquid being ejected by the machine in that:
- contact with the eyes can cause serious damage.
- contact with the skin (given the extremely low boiling point of the fluid) can cause
burns.
For this reason, it is necessary when using the machine to wear suitable protective gear
such as gloves and goggles. In the event of fluid coming into contact with eyes or skin,
rinse with plenty of running water and seek immediate medical advice.
The machine is designed to be used specifically with the refrigerants R12 or R134-a (for
use in two distinct models). It is important to avoid mixing the fluids or using them in a
promiscuous way.
The type of refrigerant (R12 or R134-a) for which the machine
has been equipped, is clearly indicated.
!
After the machine has been switched on, wait at least five minutes before carrying out
any operation. In the event that the work cycle is interrupted for any reason (e.g. lack of
electricity supply), then it is always necessary to repeat operations from the beginning of
the cycle.
Do not fill any container with refrigerant liquid that is not approved for pressures
of at least 35 bar and that is not equipped with a safety valve (the valve should be
in compliance with the directives regulating pressure vessels).
The container used to store the refrigerant should NEVER be filled to more than 80%
total capacity to avoid performance shortfalls. Check the filling of the oil containers
during machine operation, ensuring that they are not overfull thereby avoiding abrupt
losses in machine performance. Do not use these containers for other types of fluids or
materials.
