1. Machine Inspection

• Power on the machine and perform a visual exterior inspection, checking the housing, hoses, power cord, couplers, casters, and wheels.
• Is there any physical damage to the machine exterior? If so, record/describe it here:
• Is the machine displaying any warnings? [ ] Yes [ ] No
• If yes, record warnings below:
• If unable to continue to the main menu or operate the machine, contact your local Robinair Authorized Service Center for repair.

2. Filter: Check Refrigerant Filter Life

• From the Setup Menu, select "Filter Maintenance" to display the filter capacity remaining.
• Record remaining filter capacity here: _________________________
• R-1234yf filters must be replaced after 330 lbs. (150 kg) has been filtered. Replace identifier items: sample hose assembly ROB16106 and identifier filter ROB16913.
• R-134a filters must be replaced after 150 lbs.
• Order replacement filter ROB34724 or filter + oil maintenance kit ROB13172 for most models.
• For machine 17800C, order replacement filter ROB19776.
• If the filter needs replacement, follow the replacement procedure found in your machine's operators' manual.

3. Vacuum Pump: Check Vacuum Pump Oil

• Inspect oil condition through the Sight Glass located on the right side of the machine. Ensure the machine is on a flat, level surface for an accurate reading. Record oil color below:
• [ ] Clear - Oil is OK
• [ ] Amber - Oil is OK
• [ ] Green - OIL MUST BE CHANGED
• [ ] Dark Amber or Green - OIL MUST BE CHANGED
• If vacuum pump oil needs to be changed, follow the replacement procedure found in your machine's operators' manual. Use Robinair High Vacuum Pump Oil (ROB13203 or ROB13119 or ROB13204).

4. Scale Calibration Check

• Look underneath the machine front and ensure the mounted magnet is clean and free of debris.
• Select "Calibration Check" from the Setup menu and follow on-screen prompts. Record results:
• [ ] Calibration check passed

• The scale may be out of calibration. Follow on-screen prompts to recheck calibration. If calibration continues to fail, contact your local Robinair Authorized Service Center for repair.

5. Leak Check

• Select "Leak Check" from the Setup menu.
• Connect service hose couplers to storage ports on the rear of the machine.
• Follow on-screen prompts to perform a vacuum test.
• Did the vacuum test pass?
• [ ] Yes - Your machine will now perform a pressure decay test.
• [ ] No - Use a refrigerant leak detector to check for leaks. If the vacuum test continues to fail, contact your local Robinair Authorized Service Center.
• Did the pressure decay test pass?
• [ ] Yes - Your machine is ready for use.
• [ ] No - Contact your local Robinair Authorized Service Center.

6. Internal Service Vessel (ISV) and Supply Tank Check

(N/A on 34888HD and 17800C)

• Inspect the external supply tank for damage. If OK, ensure the black tank fill hose is securely connected to the supply tank and the supply tank valve is open.
• Select "Adjust Background Fill Target" from the Setup Menu, enter your desired fill target, save the new value, and exit. This will ensure your ISV is always full and ready for use.
• The machine will automatically start filling the ISV and stop when the fill target amount is reached. If the machine fails to fill the ISV, repeat the above steps or contact your local Robinair Authorized Service Center.

7. Software Updates

(34998 and AC1234-9 machines only)

• Select "Software Information" from the Settings screen on the Main Menu.
• If no update is available, the machine will indicate your software is up-to-date.
• If an update is available, a red "Update Software" icon will be shown. Tap on the icon to update software.
• Ensure your machine is connected to WiFi and has a strong connection. Do not interrupt software installation or turn off the machine while updating.

8. Refrigerant Identifier Maintenance

(R-1234yf machines only; AC1234-4, AC1234-4SL, AC1234-6, AC1234-9)

• If your machine displays a message regarding the oxygen (O2) sensor, the sensor in the machine's integrated refrigerant identifier must be replaced. Order (O2) sensor ROB16916.
• To replace the sensor, follow the replacement procedure found in your machine's operators' manual.
• Is the identifier filter white? [ ] Yes [ ] No
• If no, replace the filter.

Maintenance Check

• Wipe the airflow outlet panel, cabinet, and control panel.
• Lubricate wheel bearings and inspect brake components.
• Inspect all hoses, couplers, and power cord.
• Inspect casters and wheel locks.
