Control Panel Light
A control panel light shall be fitted to enable maintenance to be carried out during poor light conditions.
Mains Cable Entry
The unit main cable can enter from either side of the electrical control panel.
Maintenance Socket
A 10 A single phase maintenance socket is available located within the control panel. This socket enables UK plugs to
be connected.
R410A Leak Detection
The refrigerant leak detection is located within the compressor enclosure (fitted as standard with leak detection option).
The sensor is positioned at the lowest point to ensure correct operation. Detection rate of 100 ppm ensures detection in
case of refrigerant leakage. The leak detector has relay outputs allowing for alarm monitoring via the Airedale controller.
This relay output can provide facilities for refrigerant pump down for refrigerant containment.
The refrigerant leak detection assures best environment practices in accordance with the Building Research
Establishment Environmental assessment method (BREEAM) pollution section.
A premium package is available that monitors refrigeration parameters and determines if loss of refrigerant is occurring.
This can detect which circuit is leaking from these parameters making an intelligent decision of potential shut-down of
the unit.
Control Panel Low Ambient Protection
Supplementary heating can be offered to the control panel to ensure components such as LCD displays operate in low
ambient conditions.
