Before starting the set-up procedures, open the system oil drain valve and allow the unit
to depressurize.
1. Plug the unit into a proper voltage outlet.
CAUTION!
Avoid the use of an extension cord because the extension
cord may overheat. However, if you must use an extension cord, use a No.
14 AWG minimum and keep the cord length to 25 feet (7.6 meters) or less.
2. Be sure the oil drain valves on the side of the unit are in the CLOSED position.
3. Turn on the unit. The display flashes “door.” Slide the lockout panel (in the upper
left corner of the back of the unit) to expose the
1

” flare fittings for R-12, then
press SHIFT/RESET to lock in that refrigerant type.
4. Connect the R-12 automotive hose set as follows:
• Connect the 36” red hose to the RED fitting in the lockout box.
• Connect the 36” blue hose to the
BLUE fitting in the lockout box.
• Connect the 36” yellow hose to the

CAUTION!
R-134a automotive systems have

SAE specifications) to avoid cross-contamination with systems using

— system failure will result!
Important!
Because the
filter-drier has
only one access
port using a

flare fitting, you
must initially set
up the unit for
R-12.
