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.
