||Start the engine. Inspect the system and determine
if the system is operating correctly. Any repairs should be carried out prior
to recharging the A/C system.
||Check the system for refrigerant leaks using appropriate
leak detection procedures and tools (stock # 606).
||Minor leaks from O-ring shrinkage and/or hardening
can be repaired instantly by installing RED TEK® LeakStop™ A/C
Seal Repair (stock # 401). Leaks in metal lines, condensers, evaporators, fittings,
and rubber hoses can be repaired effectively by installing RED TEK® ProSeal™
Advanced Seal Treatment (stock# 402).
||Use a duct thermometer (stock# 605) to capture
and record the center vent temperature. This will supply the installer a temperature
reference, allowing the installer to compare before and after passenger compartment
||Determine the type of refrigerant currently in
the a/c system. The OEM tag is located inside the engine compartment. The OEM
tag indicates the type and amount of refrigerant in the system. If missing, contact
the OEM for further information. This must be determined before initiating a RED
TEK® 12a recharge.
||Evacuation of the refrigerant in the system is
recommended prior to installing RED TEK® 12a refrigerant. Recover all existing
refrigerants into a suitable approved container and mark appropriately, as FEDERAL
REGULATIONS PROHIBIT THE VENTING OF REFRIGERANTS INTO THE ATMOSPHERE. Although
RED TEK® 12a is compatible with most existing refrigerants and oils, DO
NOT MIX REFRIGERANTS. Mixing refrigerants is illegal in Canada and the US
and will not offer the maximum performance available from RED TEK® 12a.
||Locate low and high side service ports of the
A/C system. Generally, the low side service port is covered by a blue dust cap.
The high side service port is usually covered by a red dust cap. All current R134a
systems are compatible with RED TEK® 134a Installation Kit (stock# 502).
||Note: R-12 A/C systems will require a RED TEK®
Low Side Conversion Fitting (stock# 503) and High Side Conversion Fitting (stock#
504 or 505 or 506) which can be purchased separately.
||Determine the correct amount of RED TEK®
12 a Refrigerant required in the system with the use of the OEM refrigerant information
and the RED TEK® 12a Conversion Chart.
||RED TEK® 12a Refrigerant is installed through
the LOW SIDE SERVICE PORT AND IS CHARGED AS A LIQUID INTO A "0" ATMOSPHERIC
CONDITION. DO NOT INSTALL INTO A SYSTEM WHERE A HARD VACUUM EXISTS. DANGER!! DO
NOT INSTALL ON HIGH SIDE SERVICE PORT.
