4. MACHINE DESCRIPTION
MH-TH units are condensing units and split systems with silent housing for commercial refrigeration.
They have been designed following the style of split air conditioning units of which they keep the
main advantages: outside installation, low-noise operation, reduced size.
5. INSTALLATION
Before installing, it is necessary to make a layout of the refrigerating system; this must include the
following:
a) all components of the refrigerating system ( i.e.: condensing unit, evaporator, thermostatic valve,
electrical panel, piping dimensions, any safety devices, etc.)
b) system location
c) piping location
• Installation must only be performed by qualified staff with the necessary technical requirements,
according to the country in which the machine is installed.
•
The machine must not be installed in a closed environment where a good air flow is not
guaranteed.
• Leave enough space around the condensing unit for it to be possible to perform maintenance
operations in safe conditions.
•
Lift the machine by means of a forklift truck (or other hoisting equipment), using bands or ropes
as shown in Drawing. 2.
•
For information about weight, see the table of general features at the end of this manual.
• The machine must be fixed to the floor in a vertical position only and by passing screw anchors
(Fischer) through the relevant holes in the unit frame.
5. 1 Refrigerating connection
In order to make the connections, suction and liquid line piping with the same diameters as the
connections fitted on the machine must be provided (see the table of general features at the end of
this manual).
These diameters are valid up to a maximum length of 10m. For longer sizes, piping diameters must
be of a correct size to guarantee the proper gas speed.
Pipes must be fixed to the wall on bends and welding points and every 1.5m – 2m on straight
stretches.
