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
Page 29
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
Page 30
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.
DOC NUMBER 595R36300 30
Page 31
SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
Wait for 15 minutes before switching on the system again, to allow the gas to be evenly distributed and balance
the pressure levels.
The fine-tuning of the refrigerant charge must be done while the system is running (compressor switched on), by
observing the sight glass. The charge will be complete when there are no more bubbles forming.
When performing a condensing unit replacement always check the specified refrigerant charge.
2.6.7 Piping
Piping shall be sized so that:
It is flexible, to avoid rupture due to expansion and due to the transmission of vibration usually caused by compressors.
Ensure that the refrigerant is well distributed through the evaporator(s), and prevent the liquid from flowing back
to the compressor. To do that, use an expansion valve with proper dimensions, and an inverted siphon at the
outlet of each evaporator.
Figure 4 – Evaporator under the condensing unit
Prevent the liquid from flowing back to the compressor when the system stops and the evaporator(s) is/are located
above the Condensing Unit, using an inverted siphon and suction accumulator (see Figure 4).
Aid the return of lubricating oil coming from the evaporator(s) to the system where the Condensing Unit is located
over 3000 mm above the evaporator(s), using an inverted siphon every 3000 mm in the piping.
Allow secondary operations, such as attaching measurement instruments, isolating stretches for maintenance
purposes and pump down.
Warning: The diameter of the fittings for the condensing units and evaporators shall not be used as
a parameter to select the diameters of the other system components.
Warning: After replacement the condensing unit and its accessories must be handled and recycled
according to the material group (ferrous, non-ferrous, polymers, oils,) directives. These recommendations are intended to minimize the adverse impacts on the environment.

Suction Accumulator
2.6.8 Basic Accessories of a Cooling System
Filter-Dryer
Installed at the liquid line, its function is to retain particles and mainly remove
residual humidity from the system.
Sight Glass
It is installed at the liquid line, just after the filter -dryer and used to monitor
the system refrigerant charge. Some models also allow humidity detection.
Pressure Control
Some Condensing Units are fitted with High / Low Pressure Switches. Their
function is to prevent the compressor from operating under pressure levels
that are outside of their application range.
Solenoid Valve
It is installed at the liquid line, prior to the expansion valve and used for the
pump down procedure.
Oil Separator
It is installed at the discharge line, when the evaporator is below the compressor's height (long distances)
It is installed at the suction line, just before the compressor. It prevents liquid
refrigerant from flowing back towards the compressor.
Conditions that favor the flow-back of liquid to the compressor and where the
use of a suction accumulator is recommended:
• Systems with more than one evaporator
• High refrigerant charges
• Operations with defrosting by hot gas
• Where the distance from the compressor to the evaporator is over 15 me-
ters (50 feet)
• Evaporator(s) above the condensing unit
Fan Speed Control
DOC NUMBER 595R36300 32
The Fan Speed Control controls the head pressure in air-cooled condensers
by reducing the fan speed to maintain head pressure as the outside temperatures/condenser pressure drops. As the motor speed drops under lower ambient/load condition fan noise is also reduced.

Schrader Valve
Used for service operation (Refrigerant Charge).
Suction Filter
It is recommended to clean the systems if the compressor has burned out. Installed at the suction line, its main task is to retain the contaminants (result of
the burning of the compressor), and to retain system particles.
A/C systems can include a pressure release valve that is usually mounted at
the compressor or fuse plug mounted on the receiver dryer.The relief valve can
open at a preset pressure and then reclose.The center of the fuse plug melts
same capacity.
DOC NUMBER 595R36300 33
Page 34
SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
2.6.9 Expansion Valve
It is installed at the liquid line, before the evaporator.
Its function is to keep the pressure different between the condenser and the evaporator; it also adjusts the refrigerant flow within the evaporator. For systems operating under low evaporating temperatures (lower than -17.7°C
(0°F), it is recommended using an expansion valve fit with MOP (Maximum Operation Pressure), to protect the
compressor against high pressures during the suction phase at the start of the procedure.
2.6.10 Setting the Expansion valve
The valve is already set from factory in the standard condition and it is suitable for most installations.
If adjustment is needed, it is possible proceeding by means of the expansion valve rod adjustment.
By rotating the rod clockwise, the expansion valve overheat increases, while turning the rod counterclockwise
then it will decrea the overheating
IMPORTANT: Turn the rod maximum 45° each time; wider rotations will provoke flash-gas!
To eliminate evaporator swing, increase overheating by turning the rod clockwise until it stops.
Rotate the rod anticlockwise step by step until the swing will reappear.
From this position, turn the rod 45° clockwise.
When the calibration is done (swing approximately at the average), the refrigerator will no longer swing and the
evaporator can be considered as working at full capacity (see Figure 5).
If overheating in the evaporator is too high, this may be either due to an insufficient refrigerant fluid mass or to a
insufficiend dimension of the thermostatic valve (thermostatic valve not sized correctly).
Note: Variations of the overheating of ± 0.5 ° C are not considered swing.
Figure 5
2.6.11 Correct position of the thermostatic sensor
It is recommended to mount the sensor on a horizontal section of the suction line as close to the evaporator as
possible and in a position corresponding to the watch hands between 1 and 4.
Figure 6
DOC NUMBER 595R36300 34
Page 35
SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
The position depends on the external diameter of the tube.
When the suction pipe has an outside diameter of 16 mm or less, it can be secured both in the positions (see
Figure7):
a. above the suction line
b. by the side of its own path, in horizontal position
Figure 7
When the tube has a diameter greater than 16 mm, the sensor must be secured beneath the horizontal axis of
the tubing itself to form a 45 ° angle with the same horizontal axis (see Figure 8)
Figure 8
Warning
The sensor must never be mounted at the bottom of the suction line, as it will
:
receive false control pulses due to the oil present at the bottom of the tube itself.
2.6.12 Identification of the thermostatic valve
The thermostatic element is equipped with a laser engraving on the top of the membrane (see Figure 9).
This engraving indicates the type of valve (with the numerical code), the field of evaporation temperature, MOP
point, the refrigerant and the maximum operating pressure and the type of nozzle installed
Figure 9

SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
2.6.13 Charge MOP
All MOP valves have a very small charge in the sensor.
This means that the valve or the element should be placed in the hottest position of the sensor otherwise a charge
migration may occur from the sensor to the element and the expansion valve will stop working.
The MOP charge has a limited charge in the sensor.
MOP means Maximum Operating Pressure (sometimes called “Motor Overload Protection”) and is the maximum
suction / evaporation pressure allowed in the suction / evaporation line.
The refrigerant liquid will evaporate when the temperature reaches the MOP point. As the suction pressure increases, the expansion valve starts reducing the pressure to 0.3 / 0.4 bar, below the MOP point, until fully closing
when the suction pressure will be equal to the MOP point.
2.6.14 Quantity of refrigerant to charge
The exact quantity of refrigerant to charge (see Figure 10) in the system depends on:
Figure 10
Data plate identification (in case of remote unit the reference are points 2 and 3)
Liquid container receiver (max quantity in kg of refrigerant)
Liquid spy (see Figure 11) on the system.(where present)
Figure 11
COMPLETE OPERATIONS IN SUMMARY - After correct cleaning and vacuum of the system:
a) Start to charge the refrigerant on suction/service pipe on the compressor.
b) Keep the appliance door opened
c) Switched ON the appliance
d) Charge a small amount of refrigerant step by step without freezing the pipe until air bubbles show on liquid spy.
e) Close the door and verify the evaporation pressure.
f) Check the overheating on external pipe of evaporator following the evaporation pressure/temperature
g) Check for presence of swing of pressure due to thermostatic valve (refer to chapter 2.5.10)
h) In case of swings, set the valve or add refrigerant.
Warnings: Do not provoke flash gas!!!!! The pipe must be slightly cooled not frozen!!

2.6.15 Electrical connection
Use the separate power supply from remote unit and bcf.
For the power supply dimensioning, check the electric wiring diagram of the appliance: after retrieving current
absorption and power data relevant to the live lines, determine the cables sections able to support the ab-sorbed
current.
In order to detect the remote unit alarms, the connection between it and the BCF must be done with a six-wire
cable whose section is sufficient for signals.
The BCF electric wiring diagram shows the correspondence between the clamps of the remote unit and of the
BCF: labels are then present on both the remote unit and the BCF terminal clamps.
The main labels are:
T1-T2 = connection of power compressor
AP_AP = Alarm pressostat
AT_AT = Alarm Thermic compressor

2.8.8 Usb data transfer
The Transfer ambient is used to manage data transfer between UI and a USB key. It contains four functionalities:
- Download all: Used to copy all data (parameters, recipes,…) from UI to USB key;
- Upload all: Used to copy all data from USB key to UI;
- Download selection: Used to select, from a single category (parameters, recipes,…), which items to
copy from UI to USB key;
- Upload selection: Used to select, from a single category, which items to copy from USB key to UI.
The navigation will be the same for the generic user and the Service user, but the effects on the download/upload
operations will be different.
Service
2.8.8.1 Users management lite
Only two user profiles will be available on the first functionality release: “User” and “Service”.
“User” will be the default profile, “Service” will be accessed through password on the Settings->Service menu.
Once the password is correctly entered the “Service” credentials will be active for 15 minutes while navigating the
interface. The 15 minutes timeout is continually reset while the appliance is in running state and every time the
interface detects a touch. If the “Service” credentials are active, there has to be a “logout” button in the secondary
menu in the upper drawer to force the switch from “Service” to “User” credentials.
With “Service” credentials the user interaction will differ for the following points:
1) The download/upload functionalities will include Service parameters, including size and other characteristics related to the machine model. Anyways, the user will receive a warning popup while changing
these parameters.
2) The download functionalities for logs will include additional logs for debugging or post-mortem analysis
purposes.
3) In running state the user will have access to the top drawer. Only the data monitor button will be active.
4) The user will have full access to Service parameters setting and data monitor.
The user knows if “Service” credentials are active because on the top right of the screen will be visible the “SERVICE” label. If “User” credentials are active, the space will be left blank.

4.3.1 Over view
The compressor consists of a framework hosting the electric engine inside and the mechanical part of the compression piston.
The engine, which is suitably connected to the power supply, triggers the crank gear hence moving the pistons
to the bottom of the cylinder and activating the suction.
When the piston moves in the opposite direction, the refrigerant gets compressed and flows through the delivery
pipes.
4.3.2 Expected use of the unit
This compressor has been designed and manufactured only for the compression of the HFC-HFO (R404A,
R507, R134a, R407C, R407F, R448A, R449A, R450A, R513A, R452A) and HCFC - CFC refrigerants (when
national laws allow it only) within the operational fields as described by the attached application charts, with the
restrain of a delivery temperature of 130°C and overheating at the suction between 5K and 30K.
The employed refrigerant has to have a humidity content of 10 ppm.
What follows is forbidden
4.3.3
• The use outside the operational field and the above mentioned restrains;
• The compression of a fluid other than the above mentioned ones;
• To plunge totally or partially the compressor into fluids or to subject it to strong jets of water;
• The use into places at risk of explosion;
• The use at ambient temperatures lower than -20°C or higher than 60°C;
• The use into a completely closed place (not well aired);
• The use in places where corrosive chemical agents are present;
• The storage of combustible or flammable materials in the installation area of the compressor.
IMPORTANT: The plate of each compressor reports type and quantity of oil loaded at the factory.
For any possible topping up and/or replacement of the lube, use the type indicated on the plate only.
:
4.3.4 Compressor identification
Each compressor is identified thanks to a serial number reproduced on the riveted metal plate, in compliance
with the EN 12693 regulation; this plate specifies:
• Manufacturer’s name Compressor model Serial number Manufacture date
• Max delivery running pressure (PS, in bar)
• Max pressure of the low pressure area both in the running and in the idle condition (Psi, in bar)
• Number of phases of power supply
• Nominal voltage (V), frequency (Hz), current when the rotor is blocked (A)
• Max running current (A).
• IP protection category.
• Nominal rotation speed (RPM).
• Displaced volume (m

/h)
4.3.5 Airing of the installation room
For
preventing dangerous concentrations of refrigerant in case of unforeseable leaks, it is necessary to provide a
suitable airing in the room where the
The installation room has to be equipped with natural airing or mechanical ventilation, in compliance with the applicable
technical regulations
Since possible refrigerant leaks would tend to occupy the lowest part of the surrounding space, we recommend placing

4.3.8 Electrical connections
The connection to the power supply has to be made by opening the box of the electric connections and by connecting the phases of power supply, the equipotential wire and the wires for the signals of the temperature sensors
following the instructions provided inside the lid of the box and on the compressor plate.
Connect the carter resistance, whenever it is provided, and the other electric equipment’s.
The plate positioned on each compressor shows the motor’s voltage and frequency values: make sure they comply with the line’s voltage and frequency.

Warning
For the dimensions of the contactors, cables and protection devices (fuses, circuit breakers) of the electrical power
refer to the values of maximum working (FLA) and start-up current (LRA) shown on the unit data plate
4.3.9 Protection System
The motors are equipped with PTC internal protection or through THERMIK; as for PTC sensors, the relevant
connections (indicated as T1- T2 in the wiring diagram) shall not be connected to the power supply voltage but
fed only through the motor protection electronic module (REL), available for protections such as thermistor; vice
versa for protections such as thermic the use of (REL) is not necessary and the contacts shall be connected in
series with the other system protections.
4.3.10 Commissioning: Preliminary Works
Feed the carter resistance, if provided (start the refrigerant recharge process not below35°C÷40°C of the oil temperature).Once the indicated temperatures are reached, start the compressor.
Warning:
Before starting the compressor:
:
Make sure the suction service valve and the discharge gas valve are open;
Do not start the compressor when high vacuum conditions occur inside it. Non-observance of this
warning can have very serious consequences such as the sudden increase of the internal pressure with
possibility of explosion and consequent risks for the staff operating, passing by or staying close to the
machine.
Check the oil level and verify that the oil level is between the levels clearly indicated on the oil sight glass, as
shown in the following figure:
OIL LEVEL INDICATION
During the first hours of operation of the compressor, check the oil level several times.
Warning:
If oil have to be added, use the type indicated on the nameplate and do it gradually, checking his return to compressor: Danger of liquid slugging!
Warning:
During compressor, functioning, liquid migration from evaporator to compressor has to be avoid.
The functioning with liquid refrigerant may cause following failures:
Oil with less lubricant power;
Broken of valves and consequent damage of other components
The installer shall verify that the plant has all the solution to avoid the liquid migration from evaporator to compressor, in all possible operating conditions. This phenomenon may be identified by the following functioning
failures:
Ice or frost formation on the suction service valves and on suction line;
Excessive foam formation on lubricant, visible through warning light;
Low temperature of surface of oil sump
Take a sample of oil and verify its good quality (color and acidity).
Every time the oil is replaced, also the oil filter shall be verified.
DOC NUMBER 595R36300 87

SERVICE MANUAL Blast Chiller Freezer SKCH 30 50 70
Warning:
POE and PAG oils are strongly hygroscopic. Moisture binds itself chemically to the oil molecule.
Carefully operate while replacing the oil. Prevent the air from entering the circuit.
In case of refrigerant gas leak, aerate the room where the leak occurred before any operations. Do not stay in the
machinery room if it has not been properly aerated; even if the gas inhaled is not harmful, the gas replaces oxygen
and can therefore cause choking symptoms
4.3.11 Compressors Replacement
A particular attention shall be paid in case a compressor is replaced with another one; as a matter of fact in the
circuit, a certain oil quantity could have been left such as to cause “liquid slugging” at the start. It could be necessary to remove a certain lube quantity from the new compressor. After the compressor starting check that the oil
level is stabilized between the levels indicated in previous paragraph (4.1.1.9)
4.3.12 Compressor Disassembly
Make reference site to Dorin, for spare part catalog and instruction to disassemble.
Warning:
During operation of the machine periodically, check that the oil level is between the levels clearly marked on the
sight glass. It could be useful to provide with regular oil analysis in order to check the lack of humidity and/or
acidity.
4.3.13 Number of starts
Do not start the compressor more than 8 times per hour.
Let the machine run for at least 4 minutes for each starting.
However, be sure that numerous starting do not undermine the right oil level into the case

4.3.15 Crankcase heater installations
It is recommended to fit an oil heater in the compressor crankcase, because, if the compressor is stopped, there
is the possible storage of refrigerant inside the crankcase. The heater reduce the dilution of liquid refrigerant with
the oil. On the oil level side, the compressor crankcase is already equipped with a hole where the resistance may
be applied: See the instruction below
Insert the high temperature paste in the indi-
cated hole
(3g)
Insert the crankcase heater in the housing
moving it back and forth and turning several
times
Block the heater screwing the bushing sup-
plied
(When applicable). Tightening torque of the
bushing
10 Nm
The use of the bushing ensures an insula-
tion class
IP67 for the crankcase heater
The standard resistances are:
100 or 200 W based on compressor size;
Voltage 230 V.
Warning:
Before energizing the crankcase heater make sure, the voltage is correct and that the heater is inserted
and locked inside its seat by screwing the bush supplied
On demand the crankcase heater can be provided for different voltages or power
