RIGGING
WATER CONNECTIONS
Balancing valves must be installed on all water inlet connections to
adjust the flow through each connection.
COIL CONNECTIONS
Coils of ICE THERMAL STORAGE units are filled with a low inert gas
at the factory before shipping, to ensure an optimal internal
corrosion protection.
On site, the pressure needs to be released from the coil by opening
the pressure relieve valve and removing the pipe caps.
For NH3 coils cut the threaded pipe-end and bevel for welding on
site. Make sure to protect the unit against sparks from the cutting
process with a suitable material. Next connect the pipework to the
coil connections by welding.
1. If coils are supplied filled with nitrogen, the nitrogen pressure
should be relieved through the supplied relief valve before
removing the cap.
2. If units remain on site for a long period without being installed,
coils must be kept closed to avoid condensation and corrosion.
REFRIGERANT CONNECTIONS ON SITE
All connections in the external pipework (installed by others) must
be leak free and tested accordingly. All piping external to BAC
cooling equipment must be supported separately.
PURGE REQUIREMENTS
The installer of BAC equipment must ensure proper system purging
of air prior to operation. Entrained air can obstruct the proper flow of
glycol solution, resulting in higher operating pressures than design
and reduced thermal storage capacity.
