Initial Setup
Service Vacuum
At this point the machine clears its internal plumbing before
proceeding with setup.
1. Check the vacuum pump oil level sight glass and verify
the oil level is at the center of the sight glass.
2. When prompted, connect the service hoses from the
machine to their storage ports as shown in Figure 1.
Select to continue.
3. The machine enters a 5-minute vacuum and will automatically
enter the next set-up process when complete.
Select Oil Viscosity
(N/A for 34788NI-H)
The oil inject functionality in this machine is automatic and
timing based. The viscosity of the oil being injected signicantly
affects the accuracy.
1. Using the arrow keys, highlight your desired PAG oil
viscosity (46, 100, 125, or 150). Once highlighted, select
to accept.
2. The unit is now ready to accurately inject the chosen oil.
Adjust Background Fill Target
This machine possesses a background tank ll feature. An
external refrigerant storage vessel can be uidly connected to
the machine (using the black tank ll hose) for a continuous
topping off of the internal storage vessel. Drawing from the
refrigerant within the connected external storage vessel, the
machine will periodically charge the ISV tank to the desired
ll target.
Using the arrows and the numeric keypad, enter the desired
ll target (default amount is 4.54 kg).
Tank Fill
This procedure transfers refrigerant from a source tank to the
internal storage vessel (ISV) in the machine. The maximum
capacity of the ISV is 10 kg (22 lb). Use arrow keys to move
the cursor; use the keypad to enter a value.
1. The machine displays elds for desired tank ll amount,
charge capacity, and the amount of recoverable refrigerant
(recover capacity) within the internal storage vessel. Enter
the desired tank ll amount.
Note: Add at least 3.6 kg of refrigerant to ensure enough
is available for charging.

Note:
Charge Capacity: The amount of refrigerant
in the ISV that can be charged into a vehicle
A/C system.
Recover Capacity: The amount of additional
refrigerant that could be recovered into the ISV.
WARNING: To prevent personal
injury while working with refrigerant,
read and follow the instructions
and warnings in this manual, and
wear protective equipment such as
goggles and gloves.
