ACR2005 Refrigerant Service Solution
Introduction
GENERAL OPERATING GUIDELINES
1. The voltage at the unit must be
±
10% of the unit’s rated voltage. Errors
will be displayed on the screen. Extension cords must be a minimum of 14
AWG and kept as short as possible. Common causes for electrical
problems include:
• Long extension cords
• Faulty, overloaded electrical circuits
• Drop lights
• Incorrect ground or incorrect polarity
NOTE : If your electrical circuits have reversed polarity, the screen
displays the following messages:
VOLTAGE LINE ERROR
CHECK POLARITY
VOLTAGE READOUT WILL BE DISABLED
with an option to continue.
If you choose the CONTINUE option, the over- and under-voltage
protection built into the circuit board will be disabled. The unit may not
operate correctly. To ensure correct operation, you must use a circuit with
the correct polarity.
2. The display shows options and gives instructions for most service
maintenance tasks. Read the display prompts and follow the directions
given there.
3. To interrupt any function, press the PAUSE key, then press the
CONTINUE key to restart the procedure.
4. The ACR2005 prompts you to check the system oil drain bottle (on the
back of the unit) for recovered oil. Any system oil that is lost is
automatically drained during recovery. You must measure and record the
lost amount so you know how much new oil to add during charging. Refer
to the A/C system manufacturer’s service manuals for oil specifications.
Discard the oil following current local, state, and federal statutes, cases,
laws, and regulations.
5. In general, it is best to leave the ACR2005 main power ON throughout the
workday. This allows plenty of time for the unit to purge air from the tank and
refill the internal storage vessel. Turn the unit OFF at the end of the day.
IMPORTANT: It
is the responsi-
bility of the user
to determine if a
material is a
hazardous
waste at the
time of disposal.
Ensure you are
in compliance
with all applic-
able laws and
regulations.
