SYSTEM FLUSHING AND EVACUATION

A leading cause of air conditioning and refrigeration system failure is “failure to remove particulates and moisture from the system prior to operation”. We are involved daily in analyz- ing numbers of service problems on systems and 1/3 of those problems can be traced back to the evacuation process, or lack thereof. We hear time and time again where the system was thoroughly evacuated and a suggestion that there are particulates and/or moisture in the system isn’t given much credence. Upon further questioning, many times we discover that “It’s a new system, so there was no need to flush it, and it was evacuated down to 29 inches for at least 1/2 hour.”

NOVENT® LOCKING REFRIGERANT CAPS

These locking caps screw onto the service valve ports on refrig- eration and AC/HP equipment to prevent leakage, deter access by unauthorized persons, and prevent accidental venting. Precision machined brass caps with protective aluminum shroud require use of a special tool to add, or remove them.

Within those statements may be the problem. All new systems should be flushed. Copper shavings, flux, balls of solder, brazing flake, etc will be in the system from the installation and need be removed prior to operation.

Evacuation down to 29” for 1/2 hour simply removed some air from the system. Little, if any moisture removal was accomplished. Effective moisture removal requires the system be evacuated down AT LEAST to 500 microns and held there FOR AT LEAST 1/2 hour or more. It may take 1/2 hour just to evacuate down to the 500 micron level. What about the drier installed by the manufacturer? Won’t that remove the moisture? The small drier installed by the manufacturer is designed to handle minimal amounts of contaminants remaining after proper flushing and evacuation procedures have been applied.

Remember...... 1. Change the oil in your Vacuum pump. (Moisture laden oil won’t allow the pump to pull into a deep vacuum)

2. Change the drier on your recovery machine. (A con- taminated drier simply restricts the refrigerant flow and extends the required recovery time)

3. Always use a thermocouple vacuum gauge to determine the level of vacuum obtained. Without it you have no way of determining the moisture removal from a system. (See REM Cat # 1R242A, 1R481, 1R482, 2F460 Gauges)
