vibration isolation pad assemblies mount under steel plates welded to the chiller tube
sheets.

er. As such, it has minimum joints from which refrigerant can leak. The entire assembly
has been thoroughly leak tested at the factory prior to shipment. The YMC² chiller includes
service valves conveniently located to facilitate transfer of refrigerant to a remote refriger-
ant storage/recycling system. Condenser isolation valves allow storage of the charge in
the condenser.
