Brackets
These are used for mounting the MH-TH unit on vertical walls. The two brackets are fixed to the
wall at the desired height so as to make them match with the fixing holes of the units. We
recommend fitting rubber vibration dampers (not supplied) as well as placing the unit away
from the wall as much as possible to allow better air circulation.
Fig. 9 illustrates the assembly procedures together with a table of the data regarding bracket
sizes and maximum bracket loads.
•
Oil separator
When the distance between the condensing unit and the evaporator is more than 10 m, the
fitting of an oil separator is recommended. This intercepts the oil driven by the compressed gas
and it regularly returns it to the machine crankcase. In this way, the oil separator helps the
lubrication of the moving parts of the compressor. Moreover, by removing or reducing the oil
film on the exchanging surfaces of the condenser and the evaporator it improves the thermal
transmission of those devices.
• Separate control panel to be installed outside the cold room (electronic control)
This controls the evaporator (fans and defrosting) as well as enabling the "cold room
thermostat" for condensing unit control.

Different voltage
•
Voltage monitor
This device is used to protect the refrigerating unit from voltage increases or dips.
• Differential thermomagnetic switch
This device protects against overloads, short circuits and indirect contact.
