The outdoor unit can be installed directly in exteriors. If installed in interiors, basements, attics, etc., the outdoor air and extraction ducts must be connected. When installing in interiors, keep in mind that in the summer operating cycle, the outdoor coil condenses a large amount of water that must be evacuated through the drain. The possibility of an obstruction of the drain by foreign elements, dust or dirt. Areas where it snows regularly. If the unit is installed outdoors and at ground level, it should be raised on supports so as to avoid accumulations of snow obstructing air flow. These supports should be above the height the snow reaches normally. It is convenient to install anti-snow grids. Clearances When installing each unit, clearances should be left for: a) Air intake and discharge of the outdoor unit. b) Connection of the drain pipes and wiring. c) Air ducts. d) Maintenance servicing. e) Power supply connections. VCH ��� Location of VIR 25 to 90A indoor units � ��� ��� �� ��������������������������������������������������� � ������������������������������������������� �� VIR �� ������������������ �������������� ��� ������ ��� ��������������� ��������������� ������� ������� ��������� ��� ��� ��� Fastening the indoor unit to the ceiling When fastening, make sure it is completely horizontal, or very slightly tilted towards the drain, so as to avoid possible condensed water leaks (use a bubble level). It is extremely important to be very careful with the support of the indoor unit on the ceiling. Make sure the ceiling is strong enough to support the weight of the unit. Before hanging, check the strength of each suspension bolt installed. Outdoor unit air ducts 1.-Connect the ducts, isolating them from the unit by means of a flexible hose, preferably of non-flammable material, so as to avoid the transmission of vibrations of the unit. If the ducts are made of flexible material, they do not transmit vibrations. compressor, connecting same electrically as per the diagrams herein. Drain connections, VIR 25 to 90A indoor unit It is necessary to connect a condensed water drain pipe to the evaporating unit. Install the drain pipe through a siphon. Leave a minimum level difference of 25 mm. between the height of the unit connection and the line after the siphon. An access must be left so as to fill the siphon with water at the beginning of each season. The drain line must have a minimum slope of 2 cm. per each metre in length. Insulate the condensed water drain pipe so as to avoid leaks and damaging the floor. Drain pipe insulation 2.-On units VCH 45A, 60A, 75A and 90A, two different ducts must be installed, one for each fan up to the discharge, to avoid the recirculation of air. Insulate the condensed water drain pipe so as to avoid leaks and damaging the floor. Make sure water evacuation is being carried out correctly. 3.-If the outdoor air coil air discharge is carried out through the ducts, it is convenient to have the first 1-meter section made of galvanized sheeting so as to avoid deterioration due to a possible creeping of drops. Interconnecting units Indoor unit air ducts 1.-Connect the ducts, isolating them from the unit by means of a flexible hose, preferably of non-flammable material, so as to avoid the transmission of vibrations of the unit. If the ducts are made of flexible material, they do not transmit vibrations. 2.-It is recommendable to install a damper at each by-pass of the discharge duct for the purpose of carrying out a correct balance of the system. 3.-Leave easy access for cleaning and changing the air filters. The installation of a unit comprises: - Assembly of the unit. - Connection of refrigerant pipes. - Wiring of the unit. When installing Split units, make sure the cooling circuit is completely sealed after assembly, for the purpose of avoiding leaks. This will contribute to achieving maximum performance with minimum consumption, and will avoid serious damage to the unit. Furthermore, this is an ecological precaution. Installation of interconnecting pipes The length of the interconnecting pipes of the units should be as short as possible. The maximum admissible distances to the circuit and the standard pipe diameter are indicated in the tables and graphs below (without changing the pipe outlet diameter of the units). Drain connections, VCH 20 to 90A outdoor When there are horizontal sections of over 20 metres, it is unit convenient to have the suction line tilt 2% in the direction of Install the drain pipes of each tray through a siphon. The drain line must have a minimum slope of 2 cm. per each metre in length. The unit connections are made of copper piping with an exterior diameter of 28.5. Attention: When the heat pump is operating at outdoor temperatures of less than 5° C, the drain pipe could be obstructed due to freezing. So, if installed in exteriors, it is convenient to take this possibility into account, installing an electric heater at the drain connection and around the antivibratory elements of the the compressor. - The maximum allowable flow in any section is 15 m/s. - With the limitations indicated and without changing the diameter of the outgoing unit pipes, no siphons are needed. - The liquid should have a minimum of 1° C of subcooling at the intake of the expansion valve, so as to avoid accumulation of gas in the ascending liquid lines before entering the expansion system. - For interconnecting lines of over 25 metres, oil should be added (30 gr/m. of length). Layout 1 (Outdoor unit up) ������������ ������������� � � ����������� � � Pipes to be used When installing the pipes that join the two units, take special care in checking that the pipes used are kept clean and dry prior to installation. It is advisable to take the following recommendations into account: - Use cooling quality copper pipes only (K or L type, S/ASTMB88). - Do not work outside when raining. - The ends of the pipes should remain closed throughout the installation. - Do not leave the filter-dryers nor the compressor out in the open. - When welding, use low melting point rods. These should contain 5% silver minimum. - While welding and as long as the pipe remains hot, maintain a current of dry nitrogen so as to avoid rust and scaling inside the pipe. This could cause contamination and obstructions. - Do not use strippers at the copper-copper joints. - Connection to the units should be carried out by using the flaring method. Insulation of refrigerant pipes L: Total piping length (vertical + horizontal sections) in course and in one only direction. H: Vertical distance between units. A: Cooling liquid line. B: Cooling gas line. Layout 2 (Indoor unit up) Draining and drying ������������� ����������� � ������������ � � Since the interconnecting distribution pipes to the coil are installed in the outdoor unit, both the larger and the smaller diameter pipes are on the relative low pressure side of the system. Consequently, to avoid condensed water from the pipes dripping on the floor, both must be insulated with adequate insulation. The thickness of same should be at least 8 mm. � Air does not act as refrigerant because it cannot be liquefied by the compressor. The air and humidity that remain in the cooling system have undesirable effects, such as those listed below. Consequently, they should be eliminated completely. - High pressure increases. - Consumed power increases. - The performance of the unit decreases. - The water contained in the air can freeze and block the capillaries. - Water can cause the corrosion of certain parts of the circuit and the deterioration of the compressor. Process In each circuit: 1- Connect a vacuum pump and a service pressure gauge. 2- Carry out a vacuum of up to 50 microns, minimum. 3- Check for leaks. L: Total piping length (vertical + horizontal sections) in course and in one only direction. H: Vertical distance between units. A: Cooling liquid line. B: Cooling gas line. 10 Refrigerant charge The refrigerant charge is calculated with a pipe length of 7.5 meters. See the refrigerant charge in the table below, by models and size. Refrigerant charge and pipe diameters Nominal charge R-410A (Kg.) Number of circuits Gas line diameter Liquid line diameter Additional charge, grs.

Maximum length (L): This is the sum of the lengths of all horizontal and vertical straight sections in one single direction (liquid or gas). Maximum equivalent length (LE): This is the sum of the lengths of all straight sections of the interconnecting pipes (liquid or gas) in one single direction, plus the equivalent length of the accessories (basically elbows and bends). The equivalent length due to elbows and bends can be seen in the following table: Example: ����������� 90° bend (long radius) 3/8" 0.3 0.2 ��� 0.4 0.3 5/8" 0.5 0.4 ��� � ������������ ��� � ����������������������� ��� ���������������� 1/2" ���������������� ��� � Elbow (short radius) � ����������� Accessory equivalent lengths in meters Ext. pipe diameter ��� � ��� � 3/4" 0.5 0.4 7/8" 0.6 0.5 1 - 1/8" 0.7 0.6 1 - 3/8" 1 0.7 1 - 5/8" 1.2 0.8 L= 2 + 3 + 3 + 6 + 4 + 7 + 6 + = 31 31 < therefore, 50% is correct To calculate the equivalent length of the interconnecting pipes we use, just as we would for the pressure drop, the data of one of the liquid lines; that is to say 1/2" outer diameter. As we see in the diagram, there are 4 elbows with an equivalent length of 0.5 m. (as per table) and 2 bends of 0.4 (as per table). Therefore, to make sure that the pipe equivalent length is not over the admissible maximum, we have: LE = 2 + 3 + 6 + 4 + 7 + 6 + 4 (0.5) + 2 (0.4) = 22.8 m. 33.8 < therefore, 60 % is correct Note: The elbows and 45° bends (used in siphons, for example) have half the equivalent length of the 90° bends. 11 Adjusting the refrigerant charge For lengths over or under 7.5 m., the nominal charge should be increased or decreased by the grams indicated in the corresponding table, depending upon whether the length of the liquid line has been increased or decreased. Check to see whether the refrigerant is correct by measuring overheating. In normal summer conditions between 5 and 10° K is correct. electronic control board will not be powered and the unit will not operate. In this case, interchange two of the main power supply intake of the unit. Service valves Thermostat connection Connection of the indoor fan VIR 25A to 90A Should the phase sequence (R-S-T) be correct but the indoor fan turns in the opposite direction, interchange two phases at the bottom of the fan contactor. To connect the thermostat to the control board use a screened 10 x 0.22 communication cable. Setting the electronic board For start-up and once the accessories are installed, power the units. To have the electronic board respond in accordance with the accessories installed, press the "test" key for about two seconds, until the red LED goes off. Selecting cool only operation There are 3/8" suction and discharge service valves that are useful for a quick and correct total drain. Checking for leaks Once the charging through the 1/4" nozzles located in the circuit is complete, check for leaks. Application of R-410A refrigerant Due to the characteristics of the refrigerant, its evaporation, condensation and discharge temperature, its high operating pressure in the units, and the specific requirements needed for efficient operation (free of humidity and dirt), it is obligatory to have a specialized group of technicians, with a certificate of aptitude, handle the refrigerant. Wiring Electrical connections The established national regulations must be followed at all times. Each unit is supplied with a circuit board to which the power supply is connected by means of a fuse main switch or an automatic switch. This circuit board includes a phase detector to insure the electric sequence is R-S-T. Should this not be the case, the 12 To set the VCH outdoor unit in cool only mode set, on the YKlon A1 board, microswitch (S1) No. 5 to position ON. It is necessary to turn the board power supply of to read out the new configuration. Rotational direction of the Scroll compressors The Scroll compressors and the fans operate correctly in one single rotational direction. When turning the unit on, make sure the rotational direction is correct. If it is not correct: - The compressor does not compress. - It makes a strange noise. - The consumption of amperage is reduced. - Excessive overheating. All motors are factory wired to rotate in the correct direction. WARNING Loose cables can cause overheating of terminals or incorrect operation of the unit. Fire hazards may also exist.

Prior to approving the installation Make sure that: - Voltage is always between 198 and 254 V in 230 V units, and 342 - 436 in 400 V units. - The recommended power supply cable section is at least a minimum. - The need of regular cleaning of the air filters has been notified. - The condensed water drain is perfect and there are no leaks in the water circuit. - The guarantee card has been filled out. - Maintenance instructions have been given, or a periodical check-up contract has been signed. - The user has received operating instructions. - The rotational direction of the fans is correct. 15 Maintenance of the units sure not to damage them. Since the units are exposed to the outdoor environment, it may be necessary to use water and an detergent for cleaning. In this case, always apply from inside to the exterior, and up and down. - Outdoor air intake: If the unit includes any of the accessories, such as an economizer or a return fan, the dampers should be serviced by checking correct operation of their components (shafts, fins, motor). - Refrigerant circuit: At the beginning of each cooling and heating season, check carefully: Operating pressures, control elements, temperature variations, and carry out any other checks needed. - Mechanical and electrical operation: Also at the beginning of each season, check the amperage of all motors, the conditions of electrical connections and the operation of the safety controls. The bearings of both the indoor as well as the outdoor fan motors are of the permanent lubrication type and require no maintenance. - Integrity of the structure and components of the unit: Check the conditions of the outdoor structure and components of the unit, the non-existence of impacts or dents and correct fastening of the bolts. Check correct closing of the access doors, including the conditions of the sealing gaskets and the locks. - Hot water coil: If the equipment is equipped with this accessory: At the beginning of the heating season, check the operation of the control elements, the water in the system and the purging of air in the coil. Depending upon the area and installation, and if necessary, make sure the proportion of antifreeze is correct. To assure proper operation of the units with minimum electric consumption and a long operating life, a regular maintenance schedule should be established. The following table recommends the frequency of the usual maintenance operations, although it may be necessary to vary these, depending upon the operating and ambient conditions of each unit. Qualified technical personnel only should carry out maintenance operations, updating the log of all maintenance. Attention: Prior to accessing the interior of the units disconnect all power supplies. - Outdoor and indoor fan belts: Check belt conditions and tension. If replaced with new belts, these should be of the same type and gauge as the originals, and tension should be checked within the next 24 hours of operation. - Air filters: Slide them out of the units on their guide rails and wash. - Indoor coil: A visual inspection is recommended when servicing the filters. The entire surface of the fins must be kept free of dirt. If it requires cleaning, use a soft brush or a vacuum cleaner, making sure not to damage the fins. Never use water hoses in the interior of the compartment. - Condensed water tray and siphon: Eliminate all dirt and residues. Make sure the water drain and the siphon are not obstructed. Make sure the water is evacuated correctly. Prime the siphon (fill with water) if necessary. - Outdoor coils: Eliminate all dirt and residues found on the surface of both sides of the coils. Clean the surface of the fins with a soft brush or a vacuum cleaner, making Frequency 1 month Belts (indoor/outdoor fans) Air filters 2 months Annually X X Indoor coil (evaporator) X Water tray and siphon X Outdoor coils (condenser) X Outdoor air intake (accessory) 6 months X Refrigerant circuit X Mechanical and electrical operation X Structure and components integrity X Hot water coil (accessory) X 16 Technical characteristics General dimensions mm.

Turn main power supply to the unit off. See Figs. 1, 2, 3, 4 and wiring diagram for coil connection details. Commissioning 1. Remove the access panel to the 3-way valve, side panel motor side. 2. The water intake and outlet connections are carried out from the front (remove the valve actuator [ref. 2] for welding and reinstall afterwards. Attention: It is recommendable to install manual valves on the intake and outlet lines, so as to be able to isolate the unit from the general installation if necessary. 3. Hot water coil control board. The control board, the water intake probe and the air impulse probe are factory-installed. The wiring of the valve actuator has also been completed as per the wiring diagram. When installing at the job site, connect the telephone cable between the hot water coil accessory board (J15 or J16) and the YKlon board or the board of the second compressor located in the outdoor unit (VCH). Also connect the 24 VAC power supply hose supplied. Attention: It is recommendable to install the impulse probe (B16) in the impulse duct at one meter from the indoor unit (VIR), for improved display and readout. VIR Unit Once the water intake and outlet connections are completed, turn the power supply to the machine on. Make sure the green LED (V1) on the coil control board (A6) is flashing (accessory board configured). Should this not be the case, carry out a search and configuration of accessories by pressing the test button on the Yklon board (A1) for over three seconds, until the red LED goes on. Once this search and configuration process begins, the red LED goes on and stays on until this operation is completed. Once it goes off, make sure the green LED (V1) on the coil board is flashing to indicate the accessory has been configured. 4. Check valve actuator operation. A potentiometer, P1, on the coil control board allows modulating the 3-way valve manually to check its operation. The actuator will go back to its operating position after 30 seconds. 5. Jumper S2 (ENTALP) selection By defect, factory-set to open, selects the priority of the compressors in heat pump models. If closed, selects operating priority of the hot water coil over the compressors. Adequate for installations with very economical hot water. 6. Water pump operation relay output. The control board has a relay (K1) that, through connector J14, gives output to a volt-free contact for the operation of an installation water pump.

Up to four stages of the hot water coil can be controlled to start in accordance with the demand manager, and are limited by the impulse temperature (30, 40, 45 and 50° C). Favourable conditions are understood as water temperature being over 30° C 5’ after the valve opens. Once the system is in operation, constantly check to make sure conditions remain favourable. Should unfavourable conditions be detected, and there is a call, 20’ will be timed and conditions will be checked again. If opening is over 20%, water pump relay K1 is activated. If opening is below 5%, this relay is deactivated. If conditions are favourable, the yellow LED (V2) will be on permanently. If not, it will be off. When water temperature is below 3° C, the pump is activated and the valve opens 100% to protect the hot water coil against the risk of freezing, and this condition is maintained until the water temperature rises above 6° C. This protection is in operation as long as the fan is off, even if the machine is off or in lockout. As long as the antifreeze protection is in operation, the yellow LED (V2) flashes. As long as the hot water coil heating is in operation, the indoor fan is also on. There is a minimum air impulse temperature protection of 15° C when this accessory is installed. In this way, we avoid the discomfort that can be created when there is a very high renewal percentage with low outdoor temperatures and the indoor fan in continuous mode. If there is a call for cool, the water coil valve closes. The VA-7472-9001 (VIIR-25A and 40A) valve actuator is powered by 24 VAC by means of the red and black cables. The control signal is from 0 to 10 VAC between the blue and white cables. With 0 VAC the valve is closed (by-pass) and with 10 VDC the valve is open 100%. The actuator has 6 input selection jumpers to coincide with the operating range desired. Jumper 1. Selection of the anti-sticking function. The actuator carries out a complete cycle of open and closed valve every 24 hours. Then it goes back to the position indicated by the control. By factory default, function activated. Jumper 2 and 3.

The economiser is located in the return section of the VIR indoor unit (see Fig. 1). The control board, cables and all material necessary for installation are supplied with this accessory. Technical specifications This accessory includes the return and outdoor air dampers and a drive motor with a return spring modulated by temperature control (enthalpy probes optional). This accessory is comprised of: - Damper assembly, with motor, for outdoor air. - Damper assembly, with motor, for return air. - Control board, plastic partitions and protecting cover. - Temperature sensors for return and outdoor air and air impulsion. - Wiring assembly, ready for connection to unit wiring. - A set of panels and supports. - Screws and wall hole guides for assembly. Installation Turn main power supply to the unit off by means of main switch Q1. Prior to installing the economiser it is indispensable to know how the outdoor air duct will be connected at the job site. There are two possibilities: Top or bottom duct (Figs. 1 and 2). Install the economiser as follows: 1. Assembly of outdoor air intake by means of top duct (standard configuration). The outdoor air damper will be at the top, and the economiser cabinet should be confronted with the frame of the corresponding VIR unit filter. To fasten, use the screws, nuts and washers supplied. The panels must be removed first so to insert the screws. 2. Assembly of the outdoor air intake at the bottom duct. Remove the side supports and fit them on the opposite side. Then turn the unit fully around, as shown in the figure. For coupling to the VIR indoor unit, proceed as in the standard configuration. 3. Position of the of dampers. The stand-by position of the dampers is: outdoor air closed and return air, open. Check the position of the dampers. 4. Connection of the economiser control board wiring. Connect the economiser hose cables as shown on the wiring diagram: power supply cables (J17, 580 and 581), accessory communication cable (J16, 700), motor cables (R-red, C-black, 0-10V-grey), return probe (J13-black), outdoor probe (J3-white) and impulse probe (J6-yellow). 5. Assembly of return, outdoor and impulse air temperature sensors. Depending upon the assembly of the dampers, it is advisable to install the sensor supports as well as the return (B15), outdoor (B17) and impulse (B16) air temperature sensors at a minimum distance of at least 1 m. 64 from the mouth of the duct connected to the machine. 6. Assembly of enthalpy probe, Ref. C7400A (option not applicable). The enthalpy probes are an optional accessory that cannot be installed with the VIR unit economiser. 7. J19, J20 and ENTALP jumper selection. - J19 jumper: Open by default, selects economiser operation. If closed, selects motor-driven damper operation. - J20 jumper: Open by default, selects outdoor damper closed with high temperature/smoke alarm. If closed, selects outdoor damper open with high temperature/smoke alarm. - ENTALP jumper, S2: Open by default, selects operation without enthalpy probes. 8. Configuration of economiser control board and adjustment of minimum opening. Once this accessory is fitted, along with the necessary elements, the unit is powered on once again. Make sure the green LED (V1) of the economiser control board (A4) is on permanently. To carry out a search and configuration of accessories, press the test button on the Yklon board (A1) located on the outdoor machine for over three seconds, until the red LED goes on. Once this search and configuration process begins, the red LED goes on and stays on until this operation is over. Once it goes off, make sure the green LED (V1) of the economiser board is flashing to indicate the accessory has been configured. A potentiometer, P1, on the economiser board allows modulating the damper manually to check its operation. The damper will go back to its operating position after 30 seconds. As long as the indoor fan is on, the damper will be open proportionally to renew air circulation. Factory set default value is 10%. This minimum percentage can be set by means of potentiometer P1, or through the communication network. To set it with the potentiometer, set the minimum value until the minimum opening is reached, and then press configuration button SW1 for 3 seconds to store this value. 9. Air quality probe (optional). The air quality probe is equipped with a VOC (volatile organic compounds) sensor that compares the VOC concentration in the air with the sensor set point. If this concentration is greater, the probe activates outlet Y1 by means of a relay. The 230 VAC outlet signal between Y1 and N connects to the 230 VAC to 5VDC conversion board. This board is to be fitted next to the economiser control board and the 5 VDC signal cable should be connected to J18 on the economiser board. If the room thermostat temperature set point is satisfied and there is a call for air quality, the damper opens to minimum programmed renovation and the indoor fan turns on. Then the damper opening is increased in accordance with the maximum (30° C) and minimum (12° C) impulse temperatures. If the air quality call signal disappears, or if the thermostat calls for air quality, or if the thermostat Caution: Air quality probe Allows generating cold air by modulating the outdoor air intake damper. If conditions are favourable, the yellow LED V2 will be on and the damper will adjust to achieve an impulse temperature of 12° C. Favourable conditions in temperature mode are understood as an outdoor temperature of below 20° C and, at the same time, below the return temperature. The yellow LED on the board will be off when conditions are not favourable. Whenever the indoor fan is in operation, the outdoor damper is open proportionally to renew the air in the room. (By default, 10% adjustable value.) In winter cycle, if the thermostat calls for heat but no heat phase can be activated due to a failure, the outdoor damper will remain closed with the indoor fan in operation. Should the indoor fan fail and this is detected by the Yklon board, the outdoor air damper closes completely. � �� � � � calls for cool or heat, the damper goes back to minimum renovation. If there is no call from the thermostat and the indoor fan is in auto mode, the fan turns off and the dampers close. The probe can select three levels of air quality, depending upon the position of the jumper: � � � � � ������������������������ ������������������������������� ������������������������������ �������������� ������������� Loose cables can cause overheating of terminals or incorrect operation of the unit. Fire hazards may also exist. Therefore, make sure all cables are connected tightly.
