OIL TRAPS
Oil traps are necessary for the continued performance of the system if the indoor and outdoor
units are installed at significantly different heights.
Post start-up and servicing
Once the system is operational, the master valves are used to access the entire system for
servicing and troubleshooting. If a repair requires the entire refrigerant charge to be removed, the
master valves will allow the recovery of all system refrigerant. Simply connect the low side hose
of the manifold gauge directly to the gas side master valve to recover refrigerant, pull a vacuum,
leak check, and charge the system. When servicing the system, all valves connected to an IDU
must remain open. After service is complete, both master valves and all zone valves connected to
an IDU must remain open for proper operation.
WARNING
After servicing, the master valves and all zone valves connected to an IDU must
remain open for proper operation.
WARNING
After startup, the master valves and all zone valves connected to an IDU must
remain open for proper operation.
WARNING
Do not open valves A-E until you are ready to release the factory refrigerant
charge.
