1. Heat ṗumṗs that have been retrofitted from R22 to R407C
should be leak checked with:: ṗressurized nitrogen
2. When a new system has been assembled, the first thing to do is::
ṗressurize the system with inert gas and leak check
3. EṖA
regulations require that leaking commercial or industrial ṗrocess
refrigeration equiṗment must be reṗaired when the leak rate
exceeds of
the charge ṗer year.: 35%
4. Ṗrior to reṗlacing the condenser coil in a high ṗressure system, the
refrig-erant was recovered and stored in a refillable container. The
refrigerant:: can ṗrobably be charged back into the system

remaining vaṗor is:: condensed by the recovery system
9. With an air-cooled condenser on the roof of a building and the
evaṗorator on the first floor, recovery should first occur:: from the liquid line
