Air Evacuation Preparations and Precautions Evacuation Instructions Air and foreign matter in the refrigerant circuit Before using the manifold gauge and vacuum can cause abnormal rises in pressure, which can pump, read their operation manuals to familiarize damage the air conditioner, reduce its efficiency, yourself with how to use them properly.
3. Open the low Pressure side of the manifold gauge. Keep the High Pressure side closed. 4. Turn on the vacuum pump to evacuate the system. 5. Run the vacuum for at least 15 minutes, or until the Compound Meter reads -76cmHG (-105Pa).
Electrical and Gas Leak Checks Electrical Safety Checks WARNING After installation, confirm that all electrical wiring RISK OF ELECTRIC SHOCK is installed in accordance with local and nation- al regulations, and according to the Installation ALL WIRING MUST COMPLY WITH Manual.
Test Run BEFORE TEST RUN Only perform test run after you have completed the following steps: • Electrical Safety Checks - Confirm that the unit’s electrical system is safe and operating properly. • Gas Leak Checks - Check all fare nut connections and confirm that the sys- tem is not leaking.
