I. Quick Start Guide

Congratulations! You have acquired a high quality cooling unit. Your INTARBLOCK and INTARTOP units are specially designed to equip positive temperatura cold romos in the range from -5ºC (23ºF) to +10 ºC (50ºF), and from -15ºC (5ºF) to -25ºC (13ºF), depending on the range.

Once installed, your INTARSPLIT unit can be fully operated from the remote keyboard. The control keyboard has the following functions and characteristics.

The unit has four operation modes: Refrigeration mode.- this is the normal operation mode. The display shows the room temperature

and by pressing the set key the target temperature is shown. During the operation the electronic control keeps a record of the maximum and minimum room temperature ever measured, which can be consulted at any time.

Defrost mode.- the time on time your unit will switch to the defrost mode to eliminate the frost that has formed on the evaporator. You can also force a defrost cycle by pressing the corresponding key.

Fast cooling mode.- If you like you can activate this operation mode during the start-up of the cold room. The unit will run continuously for the preset time in parameter “CCt”, even beyond the target temperature.

Energy saving mode.- If you like you can activate or deactivate this operation mode to save energy during the night or when the room will stay closed for a long time. By activating this function the target temperature is increased according to preset value in parameter “HES”.

3. OPERATION

INTARBLOCK and INTARTOP are refrigeration machines operating under a vapour compression cycle.

Refrigeration cycle

The refrigeration cycle uses a phase change refrigerant fluid in a closed circuit, with the following four steps:

Expansion: refrigerant expansion takes place in the capillary tube between high and low pressure sections. During the expansion, liquid refrigerant cools down to the evaporating temperature.

Evaporation: In the evaporator the refrigerant evaporates under constant temperature and pressure absorbing heat from the cold room. Once the refrigerant vapour has been fully evaporated, it is slightly overheated beyond the evaporation temperature.

Compression: The resultant refrigerant vapour is suctioned from the evaporator by the compressor through the suction line. The compressor compresses the refrigerant vapour up to high pressure and temperature.

Condensation: the hot high pressure gas is desuperheated and condensed, at a constant pressure and temperature, in the el condenser by exhausting the latent evaporation to the outer ambient. Once the refrigerant has been fully condensed, the liquid refrigerant is overcooled beyond the condensing temperature.

High pressure liquid refrigerant is then driven to the capillary tube, and therefore closing the circuit.

Defrost cycle

Because of the evaporator temperature can be below 0ºC (32ºF), frost is likely to deposit on the evaporator surface through the condensation of the water vapour contained in the air. To prevent the air flow from being obstructed with the consequently loss of performance, the instrument switches automatically to the defrost operation mode every given period of time.

During the defrost cycle, by opening the solenoid valve, part of the hot gas from the compressor discharge is injected into the evaporator. The evaporator temperature is rapidly increased in order to melt the frost on it while the inside fan is off.

The defrost water is collected in the drain tray and conducted to the drain bucket. This drain bucket contains a hot gas coil to progressively evaporate the drain water to the outer ambient.

4. OPERATION LIMITS

INTARBLOCK and INTARTOP units are designed for continuous operation within the following temperature limits:

§ Centrifugal fan installation.- for CV-CF models.

1. Fix the unit to the cold room wall before installing the centrifugal fan.

2. Take out the side panels of the centrifugal box to access the fixing screws.

3. Screw the centrifugal box to the refrigeration unit and connect the fan electrical wiring.

4. Re install the side panels.

The INTARTOP unit series are specially designed for roof mounting. To do so, please follow below steps:

§ Before assembling the roof of the cold room, cut out the roof frame as indicated in the plan and dimensions chart (page 16)).

§ Once the cold room is assembled, place the unit on the roof.

§ In some operation conditions (e.g. intenstive use in wet environmment, air infiltrations, etc.), it

could be possible that the unit is not able to evaporate all condensing water. In that case, install a draining pipe in the drain bucket to a permanent draining point.

§ Finally seal with silicon the gap between the unit and the wall panel.

To ensure good working conditions and easy access for maintenance, please keep free the recommended separation around the unit.

Condensation air ducts (CV-C and CR-C models)

§ Units of CV-C and CR-F series feature a centrifugal condensation fan to be ducted. It is recommended to duct the air extraction. Optionally, it is also recommended to duct the air suction through semi-flexible ducts in aluminium or rigid ducts in PVC plastic, steel or fibreglass.

§ Failing a detailed calculation, the following chart shows the recommended dimensions according to the duct type, for an equivalent total length of 20 m and both air intake-outtake grilles.

§ It is recommended a minimum length duct, avoiding placing unnecessary turns. Failing a detailed calculation, it can be supposed that a 90º turn, with no internal radio, is equivalent to 5 m length.

§ If air intake is not ducted, an air intake adequate to the room should be planned.

§ It is not recommended the use of flexible ducts due to pressure loss, being only acceptable in case

of straight and very short stretches. If so, an aluminium semi-flexible duct as indicated diameters is recommended.

22. START-UP

Before starting the unit,plese check that the unit is properly fixed on its supports and the electrical connections are properly installed. If you have worked on the unit, take care not to forget tools or any objects inside, that there is no gas leak and that assembly-connection are properly done.

Before starting up or after a stand-by periods, activating the crankage heater (when included) at twelve hours in advance is recommended. Otherwise, the compressor must be warmed up in a different way to ensure the refrigerant-oil separation. This operation is important, specially when starting-ups in low ambiance temperatures.

Connect the electrical supply and switch on the unit with room door closed. The display will show the room temperature and after the time as specified for Ods parameter the compressor will start.

Set the cold room temperature set point and wait until the cold room temperature reaches the set point. The high temperature alarm will not be activated until the time of dAO parameter is elapsed.

Once the target temperature is reached, initialise the record of maximum and minimum temperature as indicated in thism anual. You may check that auxiliary devices work properly:

§ Room light.- turn on and off the room light.

§ Door switch.- check that the compressor and fans stop when opening the door.

Force a manual defrost cycle to check this operation mode. make sure that the evaporation coil gets clean and that the unit stays within the normal operating parameters without activating any safety device.

Depending on the application you may need to modify defrost parameters, such as time period between two consecutive defrost cycles, defrost cycle duration or termination temperature. To do so, pay attention to the defrost cycles during normal operation.

Finally you can easily test the proper operation of some of the safety devices such as:

§ Open door alarm.- by leaving the door open beyond indicated in doA parameter.

§ High pressure switch or high temperature alarm.- by intentionally obstructing the air intake of

condenser.

§ Low pressure switch or Low temperature alarm.- by intentionally obstructing the air intake of evaporator.

23. MAINTENANCE

INTARBLOCK and INTARTOP units are self-contained equipment not requiring specialised maintenance. Nevertheless, to keep your unit in an optimal working state, we recommend to periodically carrying out the following preventive maintenance tasks.

During the maintenance tasks, switch off the power supply and use gloves to avoid any possible cut.

§ External cleaning.- To keep your unit free from dust and dirtiness, simply pass a wet cloth over the cover. Do not use neither solvents nor detergents.

TORNILLOS

FIJACION

CARCASA

ATERIA DE

CONDENSACION

§ Condenser cleaning.- During the normal operation the dust and dirtiness will deposit on the coil surface and will obstruct the air flow. Periodically, and depending on the surroundings, the condenser should be cleaned. To do so, remove the external cover of the unit by removing the side screws. Use compressed air blowing from inside or a vacuum cleaner to remove dirtiness on the coil. Alternatively use a brush from the outer face of the coil. Do not force the fins to avoid deformation.

§ Cleaning the evaporator (CV).- Remove any of the side covers of the evaporator block by removing front and side screws. Blow air from outside or brush on the inner side to remove the dirtiness on the coil.

§ Cleaning the evaporator (CR).- Remove the evaporator cover panel from inside cold room. Deplace the cover to a side to access the coil. Blow or brush to clean it.

§ Drain tray.- To clean the drain tray you can use commercial detergents. In that case, make sure to remove the detergent from the drain bucket inside the condensation block. To do so you can clean the bucket with water. For CR units it is posible to dissasemble the evaporator box to access the condenser coil and the drain tray. To do so, unscrew the box from the condenser and from the lower section.

Following repair tasks should only be carried out by qualified personnel.

§ Replacement of any electrical part in the unit

§ Any modification of mechanical parts

§ Any operation on the refrigerant circuit

§ Any modification on the protection devices, control panel, control switches.

The maintenance tasks shown in this manual do not exclude any maintenance task in regulations and laws.

24. REFRIGERANT LOAD

INTARBLOCK units are specifically designed for R404A refrigerant. The use of any other refrigerant in the unit invalidates its guarantee.

Any operation related to the load, removal or replacement of refrigerant must always be carried out by qualified personnel and never by the user. Please refer to technical refrigeration manuals for such operations.

Units must always be loaded with R404A refrigerant in liquid phase through the HP nipple, in the exact quantity indicated on the data plate.

25. DISPOSAL MANAGEMENT

After the installation dispose the packaging and pallet in an environmentally friendly manner and according to your regulations. When disposing your unit or any of its parts, do it through an authorised waste management company according to laws and regulations.

26. CONTROL

The unit is managed by a electronic board and a control keyboard with the following operating modes:

Refrigeration mode

The refrigeration operation mode is driven by a thermostatic control according to the room temperature and a temperature target fixed by the user. Thus, when the room temperature is greater than the temperature target, plus a pre-set differential, the compressor starts and stops when the room temperature reaches the target temperature.

During the operation mode the display shows the room temperatura. Target temperature can be shown by pressing the

key and can be modified by pressing

and .

To protect the compressor from successive starts, short cycle timing is inbuilt.

Fast cooling mode

The fast freezing operation mode can be activated or deactivated by pressing the key

for 3

seconds. During this operation mode the compressor works continuously for a preset period as configured through the “CCt” parameter.

Defrost mode

After every preset period (fixed by the parameter “Idf”) the unit executes a defrost cycle. The unit is preset on a defrost mode controlled through the inner coil temperature. In this mode, when the evaporator coil reaches a certain temperature (as predefined value through the parameter “dtE”), or after certain time (as predefined value through the parameter “MdF”). After a defrost cycle the unit stays idle for the drain time (preset time through the parameter “Fdt”) to allow the evacuation of all defrosted water.

The unit is configured to stop fans during the defrost cycle (parameter “FnC”) After the defrost cycle and during the beginning of the normal refrigeration mode, the evaporator fan

remains stopped for the time defined by parameter “Fnd”.

Room light

Room light can be switched on and off through the key .

Keyboard

It consists of a display of 3 digits and a 7 key keyboard with LEDs to indicate operation mode and alarms.

Configurable digital input

The unit has two digital inputs. One of them is always configured as a door switch. The other one is preset as a pressure switch (PAL value assigned to parameter “I2F”). If during the interval time set by “did” parameter, the pressure switch has reached the number of activation of the “nPS” parameter, the “PAL” pressure alarm message will be displayed. When the digital input is ON the compressor is always OFF.

The digital inputs polarity depends on “I1P” and “I2P” parameters: CL indicates the digital input is activated by closing the contact; OP indicates the digital input is activated by opening the contact.

External communication

By mean of the TTL connector it is possible to connect the unit through a ModBUS-RTU compatible net to a XWEB300 monitoring system. Same TTL input is used to download or upload parameter data from a “Hot key”.
