The PARTLY COMPLETED MACHINERY discussed in this document is an
air-cooled evaporator designed and manufactured to be
incorporated in a refrigerating circuit arranged by the customer.
The
PARTLY COMPLETED MACHINERY is available in different versions,
depending on the diameter of the fan motors; more specifically,
there are models with fan motors that have a diameter of 350 and
450 mm. All the versions are available with (ED models) or without
a defrosting heater.
Regardless of the configuration, at any rate, the
PARTLY COMPLETED
MACHINERY
is supplied without a control or power logic, because it
must be inserted in the refrigerating circuit arranged by the
customer. This is why it represents a
PARTLY COMPLETED MACHINERY , as
defined by Machines' Directive 2006/42/CE: because it is not
capable of carrying out a well-defined application (without being inserted in a refrigerating circuit and without having a control or
power logic, it cannot perform the function for which it is manufactured). It can freely circulate on the market, because it is
accompanied by a correspondent declaration of incorporation by the manufacturer and by the correspondent assembly instructions,
that allow its simple integration in the final machine (which will then have to be marked CE, pursuant to the directives applicable to it,
by the subject making the integration).

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).

RCMR Pag. 36 Rev. 02 02 13
UK
Connect a previously bent pipe onto the inlet of the thermostatic valve (Figure 2-A). .The pipe will exit from the evaporator
through the pre-arranged hole or open slots and will then be connected to the liquid piping of the refrigeration system.
Seal back the cover and tighten the screws.
4.3.2 Ceiling mount
Once the thermostatic valve has been connected, fasten the evaporator to the ceiling of the cell.
The unit must only be installed in horizontal position, using the specific fastening eyelets.
Leave enough space at the back to have good air recirculation and on the sides to allow the thermostatic valve to be easily replaced
and to insert or replace the electrical defrosting heaters (if the space on the heater side is not sufficient, provide an opening on the cell
wall, sealed with a mobile panel).
Evaluate the sizes of the versions of model RCMR, as indicated in the charts in Chapter 8.
4.3.2.1 Ceiling mount RCMR_350, RCMR145__/ED and RCMR245__/ED
Proceed as follows:
Open the upper folds of the cardboard box, eliminate the inner support planks, and pull out the unit, being careful not to bump
against the outlet collector and the fan motors (Figure 3-A). To make handling of the larger and heavier models easier, it is
advisable to disassemble the basin (Figure 3-B).
Turn the air-cooled evaporator by 180°, avoiding to damage the collector, the fan motors, and (if not previously disassembled)
the condensation drainage basin (Figure 4)
Lift the unit up to the roof (evaluating and using the most suitable device, based on the characteristics of the RCMR model
chosen), check the fastening elements, and fasten the unit (Figure 5-A). On the heavier models (and if previously disassembled),
reposition the basin (Figure 5-B).

4.3.3 Refrigeration connection
On the evaporator outlet (pipe at the bottom), you must insert a syphon (Figure 2), which will be connected to the suction pipe of the
refrigeration system. Connect the pipe that was previously connected to the inlet of the thermostatic valve (Figure 2-A) to the liquid
piping of the refrigeration system.
To ensure a good tight seal and reduce the risks of breakage, perform all the junctions with a "glass" connection. If the diameter of the
pipes does not allow this connection, use suitable connecting joints.
ATTENTION: any possible braze welding on the products with risk class PED ≥1 must be performed by qualified
personnel.
ATTENTION: when connecting the piping, be careful not to force or modify the position of the collector, because this
could lead to breakages.
4.3.4 Condensation drainage connection
The piping to drain the condensed water must be connected to a male 1"Gas (2”Gas for RCMR245__/ED, RCMR345__/ED and
RCMR445__/ED) connection placed in the middle of the collection tank (the minimum slope must exceed 20%). Arrange a hole on the
cell wall near the evaporator through which the piping will exit to reach the syphoning pit. Seal the hole with silicon (having
characteristics that are suitable to cell use), in order to avoid infiltrations of hot air. In the case of a cell with temperature below zero,
the drainage line must be heated during the defrosting time with a silicon heater (optional) placed inside it. This heater will be
powered with 200V and will have power outputs between 50W and 75W, depending on the RCMR model. In case of different power
supplies, contact our Technical Office.
4.3.5 Electrical connection
The electrical power supply (even in terms of voltage and frequency) provided by the Purchaser must be sufficient to properly power
the unit. More specifically, it is necessary to adopt the following indications:
The power supply wire must be well-stretched (no wind-ups and overlaps), in a position not exposed to possible collisions or
tampering, it must not be near liquids, water, or heat sources, and it must not be damaged (if it is, have it replaced by qualified
personnel).
Arrange a differential magneto-thermal switch between the power supply line and the machine that is adequately sized for the
application and according to the laws in force in the country where the machine is installed, and make sure that the line voltage
corresponds to the voltage indicated on the plate (see label applied on the machine); tolerance allowed: ± 10% of the nominal
voltage.
ATTENTION: the differential magneto-thermal switch must be placed right near the machine, so that it is in clear view
and accessible to a technician in the case of maintenance.
The diameter of the power supply wire must be adequate to the power absorbed by the machine.
On the evaporators that have defrosting heaters, a mechanical thermal switch must be installed that is appropriately calibrated,
so that it may disable the heaters in case of over-temperature. The bulb of the thermal switch must be positioned in the finned
pack at the highest point of the evaporator.
ATTENTION: It is mandatory by law that the machine be connected to an efficient grounding system. Any responsibility
for inobservance of this provision is rejected; any responsibility is also rejected were the electrical system to
which the machine is connected not to be set-up in accordance with the norms in force.
The shunt box is located on the opposite side of the outlet pipe (see Chapter 8, Figure 14 Figure 15). The terminal board where power
is supplied to the motors of the heater of defrosting and of discharge heaters (if included) is inside it.
Near the derivation box on the model RCMR_45__/ED there is a screw for the grounding connection of the cooling unit.
To insert the wires in the quick-connect terminal board (Figure 9), follow the instructions provided below:
