Lead/Lag Connection (Twin)
For Twin Systems, both evaporators can be connected to a single mains supply. Separate mains supplies can be installed if
required but it is desirable for them to be taken from the same supply phase.
The JCC evaporators come pre-fitted with an electronic controller as standard. For the Twin system, one of the evaporators
needs to be designated as the Lead Unit with the other being the Lag Unit. The Lead Unit controls the cellar temperature by
operation of the liquid line solenoid valve. The Lag Unit has no control over system operation and will just provide cellar
temperature indication.
