Follow the information on the ACX2281 rating plate.
1 Set the ACX2281 on a flat, vibration proof surface.
2 Actuate the caster brake to stop the ACX2281 from rolling.
3 Connect the power supply cable to the power supply.
4 Switch on the main switch.
The unit must be positioned on a stable, horizontal surface to
ensure correct operation. Unit must be in an area with proper
ventilation and at least 10cm from any potential obstacle to
its internal ventilation.
Keep unit out of rain and excessive humidity as moisture
could cause irreparable damage.
Prevent exposure to direct sunlight and excessive dust.
Unit must be properly grounded with the power plug ground
pin. Failure to ground unit can cause damage and constitutes a
risk of fatal injury or shock to the operator.
Do not unplug any internal electrical connections and only
have internal components opened and repaired by trained

7.2 First start-up verification
Warning – Risk of frostbite from escaping
refrigerant
Refrigerant causes frostbite on the skin
Check the service hoses for damage
Firmly connect the service quick-
release couplings to the service hoses.
Wear protective goggles.
Wear protective gloves.
Execute the following actions in sequential order by following
the procedure as shown on the display:
—
Gas weight check (vacuums entire
refrigerant circuit to ensure no
contaminants are in system prior to
filling
—
First internal cylinder fill
It is possible to interrupt the initial check and print a report
in which the status of the check is reported (if printer option
was purchased).
Equipment cannot operate in automatic mode until all the
steps of initial check are completed.
1. Set the internal cylinder fill to desired quantity (min. 3kg).
2. Follow on-screen instructions.
3. Make sure hoses are disconnected from any external
source at this time.
4. Start the procedure that initially creates vacuum in the
internal refrigerant circuit (approximately 15 minute
process).
5. Once message is displayed, the unit can be connected to
the external cylinder and the valves opened.
6. Just before the targeted refrigerant amount is reached,
unit will pause and prompt user to close external
refrigerant tank connection.
7. Once this is done, the unit will continue to recover the
refrigerant from the hoses and end once this is completed.
The total amount recovered will then be displayed.
