Operating Instructions

CHARGING THE VEHICLE

The ACR2005 has a built-in default charge amount of two pounds (.91 kg).
Other charge amounts can be programmed in pounds and hundredths, pounds
and ounces, or kilograms.

NOTE

: To achieve optimum performance, it is

important to pull a good vacuum before charging. The ACR2005 automatically
prevents you from starting a full charge into an insufficiently evacuated
system. If this occurs, follow display prompts.

1. Service hoses should be connected to the system, and the service couplers

should be open.

2. Press the

CHARGE

key

(or the

SCROLL MENU

key to reach the screen

with the

CHARGE

function key; then press

CHARGE)

3. You now have several options:

• Press

the

NEXT

key to accept the 2.00 lb. default.

• Press the

UNITS

key to change programming units. If you press the

UNITS

key again, the program toggles through pounds and hundredths,

pounds and ounces, and kilograms. Stop on the unit of measure you want.

• Use the numeric keypad and directional arrows to change the

programmed amount of the charge.

• Change the default charge program. The unit will charge through the

high-side unless you program it for low-side charging. To do this,
press the

LOW SIDE

key.

4. After you have selected the units, high- or low-side charging, and the

amount to charge, press the

NEXT

key to enter your selections.

5. You will now be prompted to press the

START

key to begin the charging

process, or the

BACK

key to change variables.

6. Upon pressing the

START

key, the ACR2005 begins to charge the A/C

system. IT IS IMPORTANT THAT YOU DO NOT DISTURB OR BUMP
THE ACR2005 DURING CHARGE, AS ANY JARRING MOVEMENT
CAN AFFECT THE CHARGE ACCURACY.

IMPORTANT:
For greatest
accuracy, do
not disturb the
unit during
charging.

REPLACING SYSTEM OIL

The system oil lost during recovery must be replaced. After evacuation,
immediately measure the amount of system oil captured in the oil drain bottle.
Discard the oil following current local, state, and federal laws. Add system oil
following the instructions provided with your oil injector.
