Following factory testing, the JCC2 range of R410A Cellar Cooler systems as noted above can now operate with extended pipe runs up to a maximum of 25 metres.
The systems are installed in exactly the same way as previously but the following must be noted:
The additional refrigerant charges for pipe lengths above 7.6 metres have changed and are now as follows:
- JCC2‐25E: 10g/m
- JCC2‐40E: 15g/m
- JCC2‐50E: 15g/m
- JCC2‐60E: 20g/m
For systems with pipe lengths above 15m, a condenser fan speed controller should be fitted. Additionally, if the system pipe length exceeds 15m, then the minimum cellar/room temperature will be +6°C.
