4.3 Installation
DANGER :
the Manufacturer rejects any responsibility for possible damages to things and/or persons
stemming from improper interventions performed by unqualified, untrained, or unauthorized
personnel.
The following Individual Protection Devices are necessary to perform the task being examined:
Before proceeding with the installation, a project of the refrigeration system must have been developed, which defines:
all the components of the refrigeration system (e.g. condensing unit, evaporator, thermostatic valve, electrical panel, piping size,
any possible safety components, etc.);
placement of the system;
path of the piping.
The unit must be exclusively installed with a ceiling mount. For other applications, consult the Technical Office of the Manufacturer.
In Chapter 8, you can view the minimum recommended safety distance from the rear wall and from the side walls, needed to provide
good air recirculation and to perform maintenance in safe conditions.
Make sure that the structure on which the air-cooled evaporator will be fastened is adequate to its weight.
Do not air-condition the fan motors, so as not to increase load loss.
ATTENTION:
special operating conditions, such as cells that are too low, excessive stocking, obstacles to the air jet, may
affect the declared performances.
The coil are supplied with tube closed. Check the integrity of the circuit by operating the valve positioned on the outlet collector. All the
cooling units are supplied with a nitrogen load. Discharge the nitrogen load before performing the braze welding
ATTENTION:
any possible braze welding on the products with risk class PED
≥
1 must be performed by qualified
personnel.
4.3.1 Assembling the thermostatic valve onto the RCMR (not included in the supply)
Proceed as follows:
Appropriately size the thermostatic valve, which will have to be installed with the outer balance. Loosen the 4 screws (7 on the
models RCMR_450) that fasten the panel on the collector side (pipe exit side) and unthread it (see
Figure 2
).

Connect the outlet of the thermostatic valve to the distributor that is already provided with a flanging connection (except for
models RCMR 33506__/ED, RCMR 43506__/ED and RCMR_45___/ED).
Arrange the outer balance pipe, which will have to be connected onto the thermostatic valve and near the end of the evaporator
collector (
Figure 2-
B).
Position the bulb of the thermostatic valve right before the outer balance pipe, placed on the suction collector. Fasten it onto the
upper portion of the suction pipe with metal clamps (
Figure 2-
C).
