1.4.1 Residual Risks
The machine has several risks that were not completely eliminated from a design standpoint or with the installation of adequate protection devices. Nevertheless, through this manual the Manufacturer has taken steps to
inform operators of such risks, carefully indicating the personal protection equipment to be used by them. Sufficient spaces are provided for during the machine installation stages in order to limit these risks.
To preserve these conditions, the areas around the machine must always be:
Kept free of obstacles (e.g. ladders, tools, containers, boxes, etc.);
Clean and dry;
Well lit.

2. INSTALLATION AND COMMISSIONING
Refer to IN (Installation manual) code 595R361””
Refer to the installation drawing for information about supply power connection and general clearances of the
unit sides from walls and ceiling.
IMPORTANT: servicing the unit requires access to the rear side; it is therefore needed to either provide
enough space to move the unit from its working position or installing the unit with space enough all around it.
IMPORTANT for remote connections piping configuration:
servicing the unit requires access to the rear side; it is therefore needed to either provide enough space to
move the unit from its working position or installing the unit with space enough all around it.
Furthermore, it is highly recommended connecting the unit by using hoses in at least three turns, like shown in
the picture below, to allow acceptable movement of the unit without causing damages or fractures (picture reports the scheme of 30kg model).

2.6.1 Technical Instructions / Installation Precautions
The instructions below are general guidelines, but they do contain the major points that shall be taken into account for proper and safe product installation for assuring best performances and preventing warranty voidance.
Caution: Refrigeration systems are pressurized circuits! It is therefore of the utmost importance that
the condensing units are removed and / or installed only by technically qualified personnel, with
knowledge of the equipment and of the processes to be adopted.
2.6.2 General Information
Inspect the unit for detecting possible damages occurred during the transport: report to the carrier immediately if any damage.
The warranty does not cover damage due to storage, transport or installation of the condensing unit
carried out in the wrong position.
Warning: Make sure you have read and understand all procedures and caution messages before
you execute any maintenance or installation tasks! It is imperative – for your own safety - that the testing
devices used are functioning well and properly sized.
2.6.3 Basic Installation – Overview
The installation site shall be well ventilated, ensuring that there will be sufficient air flow behind the condenser
(refer to Figure 1)
Figure 1 – Natural airflow through the roof
If the flow of air to the condenser is limited (or even partially blocked), system performance and reliability can be
drastically reduced. Condensing units are designed to operate at ambient temperatures up to 43°C (110°F).
Therefore, make sure that the temperature at the installation site does not exceed the recommended limit.
Warning: it is necessary to periodically clean the condenser, so that no particles damage or block
the air circulation.
Warning: pay the utmost attention when working with flammable refrigerants.
DOC NUMBER 595R36300 28
SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
2.6.4 Installation Steps
INFORMATION:
Select and size the equipment needed to assemble the refrigeration system according to the project specifications
(pipes, valves, accessories, condensing unit). Carefully observe the scope for each model.
IMPORTANT: Size pipe/hose based on the condensing unit dimensions (do not size based on the evapo-
rator).
Phases
1. Weld the pipes to the condensing unit and evaporator connections. Check the seal (leak test) in
all soldered or threaded connections.
2. Obtain the vacuum in the circuit (check with the pressure gauge if the vacuum is stable).
3. Fill the required refrigerant mass (kg): the gas should preferably be charged in the liquid phase.
4. To ascertain the correct behavior of the system, switch ON and monitor:
a. Low/high pressures
b. Liquid/gas lines suction temperatures
5. If detecting low performance or excessive pressures, fine tune the set up by either filling more
refrigerant or discharging it until reaching the correct pressures/temperatures (see below additional general notes for more details).
Refrigerant mass set up:
• Taking into account both the temperature set on the BCF chamber and the temperature where the remote
condenser is installed, when the liquid/gas lines suction temperature gets closer to the design values, proceed
with the final adjustments (phase 5 mentioned above).
• The superheating at the evaporator (given by the difference between temperatures at the piping surface at
the point where the expansion valve's sensor is fixed, and the evaporation temperature
5°C and 10°C (9°F and 18°F). Superheating at the compressor’s inlet must be between 10°C and 15°C
(18°F and 27°F), where in such case it is the difference between the temperature at the surface of the return
pipe, at a distance 150 mm (6") from the compressor, and the evaporation temperature. The sub-cooling in
the condenser shall be between 3°C and 10°C (5°F and 18°F), i.e., the condensing temperature less than
the temperature at the pipe's surface at the condenser's outlet.
(*) Evaporation temperature obtained by converting the suction pressure into temperature.
Cleaning the System (in case condensing unit replacement):
• Cleaning the system before installing a new condensing unit is mandatory to completely remove residues and
other contaminants.
• The manufacturer recommends the installation of a filter-dryer at the suction line during the cleaning operation
to retain and filter any undesired particles
• It is recommended to make the joints by braze-welding
Welding operations:
• While welding keep nitrogen (N2) circulating into the pipes with a pressure between 1 and 2 psig (equivalent
to 1.08 - 1.15 bar): this will prevent oxidations and scale forming, hence ensuring that the piping is free from
any contaminants (oil, grease, oxides).
• Use a damp cloth when welding valves or fittings or pipes to prevent the components overheatingbecause of
the heat propagation.
• The compressor and the filter- dryer are extremely susceptible to humidity. As such, they shall only be opened
during installation or replacement phases. In case of opening, do not leave them exposed to air for more than
10 min.
Leakage test
• During the system leakage tests, never pressurize the pipes using air, oxygen or acetylene. There is a poten-
tial risk of fire and/or explosion.
(*)) shall be between
DOC NUMBER 595R36300 29
SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
• After the installation is finished, pressurize the system using nitrogen and/or a small refrigerant charge up to
100 psig (equivalent to 7,8 bar); never use pressures higher than 150 psig (equivalent to 11.35 bar) for preventing the low-pressure switch damage.
.
(Figure 2) Leakage tests with soapy water bubbles
• Check for leaks using an electronic detector or a halide detector (torch). An alternative method is to check
leakage with soapy water bubbles (see Figure 2). When all fittings are properly checked, depressurize the
system and go to the next step.
2.6.5 System Evacuation
Warning: Never use the compressor itself to evacuate the system, nor energize the system when it
is under vacuum, as it may cause the compressor be damaged because of short-circuit caused by overload.
To evacuate the system, use a high vacuum pump and a vacuum gage. The system shall be evacuated up to
0,5mmHg (equivalent to 0,0066bar) or less. In any case, at least 20 minutes of vacuum must be applied (see
Figure 3)
Figure 3 – Vaccum operation scheme
Warning: Never use anti-freeze elements (methyl alcohol and derivates), as they cause irreversible
damages to the cooling system.
2.6.6 Procedures for Refrigerant Charge
The refrigerant shall only be charged after the proper vacuum has been achieved. Please check on the compressor or condensing unit tag what is the type of refrigerant that should be used to charge the system. Break the
vacuum only when the compressor is switched off.
It is recommended that the refrigerant charge be provided in the liquid state (with the compressor switched off),
through the high side (tank liquid valve) and by the refrigerant mass measurement (kg), according to the system
specification.
