4Important warnings
Mya 4 should only be operated by trained and competent personnel.
As with all chemistries, a full risk assessment should be performed prior to using the Mya 4 Reaction
Station, and care should be taken to monitor reactions at all stages. If the Mya 4 unit is left
unattended whilst in operation, it is the user’s responsibility to ensure that local rules for
unattended working are complied with.
Please read the following warnings before using Mya 4, and ensure you fully understand them.
The user must:
•only operate Mya 4 in a fume hood with protective safety sash,
•ensure that Mya 4 is positioned on a level surface, and that all vents and fans are unobstructed,
•always read the instructions for any third-party equipment (e.g. recirculator/chiller, pumps) to
ensure no safety recommendations or manufacturing warranties, when used in conjunction with
Mya 4, are contravened,
•ensure Mya 4 is correctly set up, and be responsible for the continued maintenance of the Mya 4
Reaction Station, and all of its accessories,
•ensure the working temperature range of the Mya 4 Reaction Station is -30 °C to +180 °C,
Note Mya 4 can be used at ambient temperatures ranging from 10 to 30 °C.
•take care not to touch the aluminium inserts or reaction vessels during and after heating/cooling,
as there is the risk of burns from hot or extreme cold surfaces (Mya 4 inserts can remain hot for a
considerable time after the heating source has been switched off),
Note When the Mya 4 Reaction Station and Control Pad are both on, a heatwave or snowflake
warning icon will be displayed on the Control Pad to indicate when a zone is at 40 °C or warmer,
or 0 °C or colder.
•check that all fluid hoses and connections are in good condition, fully secure and not leaking,
before starting any experiments,
•always wipe away any chemical spills immediately, and avoid exposure to strong vapours such as
HCl, etc. Mya 4 external surfaces are resistant to the majority of solvents and splash-resistant to
dilute acids and alkalis at room temperature, however, continued exposure to chemical vapours
or liquids will cause corrosion to metal and/or plastic components.
Note Mya 4 can be used with a circulating cooling fluid at a temperature from 5 °C to 35 °C
without damage to the unit. Some condensation may be observed when working at the lower
temperatures.
•regularly perform careful inspection of all fluid connections to Mya 4.
•ensure all wires and cables connecting auxiliary equipment are in good condition, and secured so
that they cannot come into contact with Mya 4 surfaces or moving parts.
