Refrigerant Gases; Refrigerants Safety Datasheet - MTA TAEevo Tech MINI Operating And Maintenance Manual

Do not use flammable liquids to clean the unit when it is running. If chlorinated hydrocarbon non-flammable fluids are used
for cleaning, safety precautions must be taken against any toxic vapours that may be released.
ATTENTION
Before removing any panels or dismantling any part of the unit, carry out the following operations:
- Isolate the unit from the electrical power supply by disconnecting the supply upstream of the power feeding line.
- Lock out the disconnect switch in the "OFF" position by fitting a padlock.
- Affix a tag to the disconnect switch handle stating "WORK IN PROGRESS - DO NOT SWITCH ON".
- Do not set the electrical power switch to ON or attempt to start the unit if it has been tagged out with a warning sign.
Coloured tracers can be used in service-maintenance operations.
Inspect all refrigerant circuit unions including connectors, flanges, and more generally all critical points (open unions) in
order to prevent possible leakage of refrigerant gas.

The units are charged with R134a refrigerant (TAEevo Tech MINI 02-03) or with R410A refrigerant (TAEevo Tech MINI
05÷10).
Do not replace or mix one gas with another because different gases are not mutually compatible.
To clean out a very heavily contaminated refrigerant system, e.g. after a refrigerant compressor burnout, a qualified
refrigeration engineer must be consulted to carry out the task.
The manufacturer's instructions and local safety regulations should always be observed when handling and storing high
pressure gas cylinders.

INDICATION OF THE DANGERS
Asphyxia
Unknown
FIRST AID MEASURES
Do not give anything to unconscious persons
Take the person outdoors. Use oxygen or artificial respiration if necessary. Do not
administer adrenaline or similar substances
Thoroughly wash with plenty of water for at least 15 minutes and call a doctor
Wash immediately with plenty of water.
Remove contaminated clothing immediately
FIRE-FIGHTING MEASURES
Any means
Pressure increase
Cool the containers with water sprays
MEASURES IN THE EVENT OF ACCIDENTAL LEAKAGE
Evacuate personnel to safe areas. Provide adequate ventilation. Use means of personal
protection
Evaporates
Evaporates
HANDLING AND STORAGE
Tightness test. Do not carry out any pressure tests with air/R134a mixtures. It can form a
combustible mixture with the air at pressures above atmospheric pressure when the ratio
in volume exceeds 60%
Close properly and store in a cool, dry well-ventilated place
