It includes crankcase heater for cooling only units. The purpose of the heater is to keep the oil in the compressor at the correct temperature while the compressor is stopped, so that it can be properly lubricated when starts again. When the unit is operating at low outdoor temperatures (below 19ºC), it is advisable to fit a crankcase heater. For long distances applications, proportional winter control must be installed. PROPORTIONAL CONDENSING PRESSURE CONTROL (outdoor unit. Not available for MODELS 060-070080 with centrifugal fan) It is an element that regulates outdoor fan speed, in order to control condensation temperature. Thus, the unit will be able to operate in the cooling cycles when the outdoor temperature is below 19ºC. This kit includes crankcase heater for cooling only units. MAIN SWITCH (only MODELS 048-060-070-080 with centrifugal fan) The main switch is located on the access panel to the electrical box, in such a way that the unit is disconnected when the panel is opened, for the models KCCK / KCHK. COMPRESSOR ACOUSTIC JACKET (outdoor unit) Each compressor is fitted with a compressor acoustic jacket this provides attenuation of the compressor noise that radiates from the unit when in operation. 1.12.- INDOOR UNIT OPTIONS KIT CONDENSATE PUMP As an option, a condensate pump is available to ensure condensate removal; also the kit is supplied with a float switch which makes the unit stops in case the pump is broken or the drain is choking (see unit description of page 15, for condensate pump position). To ensure that the condensate flows, the drain tube must be installed with a fall of 2% without obstructions, or without rising sections. To avoid any unpleasant odours from the drainage system, a trap must be fitted with a trap depth of no less than 50mm. The condensate pump has a maximum lift of 200mm. The rising tube must always be vertical. On completion the drain line must be insulated. The condensate pump is supplied with a cover panel which can be removed from the unit in case could be necessary.

SEE LOCATIONS AND SIZES FOR THE OPENINGS IN THEIR STANDARD AND OPTIONAL POSITIONS ON THE GENERAL MEASUREMENT DRAWINGS. 2.6.- DUCT INSTALLATION Duct calculation and design must be effected by a qualified technician. The ductwork dimensions should be determined in accordance with the air flow circulating through it and with the available static pressure of the unit. This data appears in the corresponding Technical Documentation. Various suggestions are made here below, regarding the layout and design of the said ductwork: 1- Whatever type of duct is used, it should not be made of materials which are flammable, or which give off toxic gases in the event of a fire. The internal surfaces should be smooth , and not contaminate the air which passes through. It is advisable to use isolated sheet metal duct in order to avoid condensations and thermic charges. 2- At the points where the duct joins with the unit, it is advisable to use a flexible connection which absorbs vibration and prevents the transmission of noise inside the ductwork and allows the unit access. 3- Bends should be avoided as much as possible near the unit outlet. If unavoidable, they should be as slight as possible, and internal deflectors should be used when the duct is of large dimensions. 4- For heat pump indoor unit, room height has to be taken on account because for long heights the hot air should go on to the top, and this makes difficult conditioning the room. In this case, the return and discharge grilles should be positioned adequately and have the suitable dimensions. 22 2.- INSTALLATION 2.7.- DRAINS GENERAL RECOMMENDATIONS: For drain piping, it is advisable to use PVC copper and steel tube. For drain tube, use a sealing material. Do not make any drill on the unit base: the drip tray could be damage. Slightly tip the unit toward the drainage side as the picture shows. If heat pump outdoor unit is going to be installed for working with outdoor temperatures below 0ºC, an electrical heater must be installed around the drain pipe in order to avoid ice formed and not get obstructed. INDOOR UNITS LNXO: They are provided with two 1/2” male steel threaded drain pipe welded to the drip tray located at both sides of the unit, which can be used faintly to adapt the installation requirements.

The wiring must comply with the regulations in force. Make sure the earth cable connection is correct. IN ORDER TO CARRY OUT THE ELECTRICAL CONNECTIONS, FOLLOW THE ELECTRICAL DIAGRAM SUPPLIED WITH THE UNIT REMEMBER THAT THE COMPRESSOR IS A SCROLL TYPE COMPRESSOR Scroll type compressors only compress in one direction of the rotation. Single phase models are always started up in the proper direction; however, the three phase models, turn in either direction depending on the order of the power supply phases. Therefore, it is essential that the phase connection for scroll-type three-phase compressors be carried out correctly, that is why these three-phase compressors are supplied as standard with a three-phase detector, which avoids the unit starts unless the connections are made on the right way. The direction of the rotation is right when an indicator-light turns ON. If the connection is wrong, this indicator will not light and the rotation will be reversed. If this occurs, the solution is to disconnect, switch the wires between two of the phases and connect again.

This fact makes that the operations of installation, service and maintenance must be special, for the next operations: SYSTEM EVACUATION Vacuum must be done until the absolute pressure does rise -750mm Hg during an hour, since the compressor oil high hygroscopic degree can cause corrosion in some metallic materials. REFRIGERANT CHARGING To maintain the mixture composition, the refrigerant must be charged always in liquid phase. For what it is necessary to have special caution when it is little quantity of refrigerant in the bottle. LEAKS If a leak takes place in the system that has produced an important evacuation of the refrigerant charge, instead of recharging the system, it is convenient to eliminate the whole charge completely, the system must be evacuated and charged again or to introduce the charge according to an specified value. OPERATION On a system operated with refrigerant R407-C, during the evaporation phase at constant pressure the temperature increases; and during the condensation phase at constant pressure the temperature decreases a certain value. Consequently, the terms “evaporation temperature” and “condensation temperature” should be redefined. PRECAUTIONS TO BE TAKEN IN THE USE OF R-407C Refrigerant: R-407C Refrigerant is used in the unit; therefore, the following precautions characteristic of this gas should be taken: - The Vacuum Pump must have a Check Valve or Solenoid Valve. - Pressure Gauges and Hoses for the exclusive use with R-407C Refrigerant should be used. - The charge should be carried out in the Liquid Phase. - Always use scales to weight-in charge - Use the Leak Detector exclusive for R-407C Refrigerant. - Do not use mineral oil, only synthetic oil to ream, expand or make connections. - Keep pipes closed before using them and be very thorough about any possible dirt (dust, filings, burrs, etc.). - When there is a leak, gather what is left of the charge, create a vacuum in the unit and completely recharge with new R-407C Refrigerant. - Brazing should always be carried out in a nitrogen atmosphere. - Reamers should always be well sharpened. REMEMBER THAT THE COMPRESSOR IS A SCROLL TYPE COMPRESSOR: Scroll type compressors only compress in one direction of the rotation. Single phase models are always started up in the proper direction; however, the three phase models, turn in either direction depending on the order of the power supply phases. Therefore, it is essential that the phase connection for scroll-type three-phase compressors be carried out correctly, that is why these three-phase compressors are supplied as standard with a three-phase detector, which avoids the unit starts unless the connections are made on the right way. The direction of the rotation is right when an indicator-light turns ON. If the connection is wrong, this indicator will not light and the rotation will be reversed. If this occurs, the solution is to disconnect, switch the wires between two of the phases and connect again. 3.3.- PRELIMINARY CHECKS 1 Check that drain pipe connections, syphon installation, and their fixtures are secure and that the level of the unit is tipped toward the drain. 2 Inspect the state of the ducts and grilles (clean and open grilles, no breaks in the duct, etc.). 3 Check that the power supply is the same as stated on the Rating Plate which is in agreement with the electrical diagram for the unit and that cable sizes are correct. Check that tightness of the electrical connections to their terminals and to ground. 4 Check the control panel connections. (If the connection is wrong, the unit will not operate and the control panel display will not light). Inspect the Air Filter, which should be in its housing and correctly positioned (the metal grille should be toward inside). Air filter Air return duct 5 Check, with your hand, that the fans turn freely.

This heater is activated when the compressor is off and stops working when the compressor is on. About eight hours before start up or after a long shutdown period, voltage should be supplied to the unit so that this heater will be activated. - To start the unit, follow the instructions given in the Control Panel Manual supplied with the unit (requesting operation in any of the modes, cooling, heating, or automatic). After a time lapse, the unit will start. - With unit operating, check that the fans are turning freely and in the proper direction. REMEMBER THAT THE COMPRESSOR IS A SCROLL TYPE COMPRESSOR Scroll type compressors only compress in one direction of the rotation. Single phase models are always started up in the proper direction; however, the three phase models, turn in either direction depending on the order of the power supply phases. Therefore, it is essential that the phase connection for scroll-type three-phase compressors be carried out correctly, that is why these three-phase compressors are supplied as standard with a three-phase detector, which avoids the unit starts unless the connections are made on the right way. The direction of the rotation is right when an indicator-light turns ON. If the connection is wrong, this indicator will not light and the rotation will be reversed. If this occurs, the solution is to disconnect, switch the wires between two of the phases and connect again. - Connect high and low pressure gauges and check that operating pressure values are normal. - Measure electrical consumption for the unit and check that it is near what is indicated on the Rating Plate. - Check the electrical consumption of the compressor and the fans with what is specified in the physical data sheets. - In the case of a Heat Pump unit, make a cycle change on the Control Panel checking that the 4-way valves make the change correctly. Check the pressure values in the new cycle. - UNIT PROTECTIONS: 1.- Electrical protections: à Compressor start temporize 3 minutes. Avoid continued compressor starts. à Thermal compressor protection (three phase models). Protects from a high compressor absorbed power. To reset this protection, push the thermal protection button (located at the outdoor unit electrical box). à Three phase detector (three phase models). Explained before. à Protection fuses outdoor-indoor unit connection. 2.- Refrigerant protections: à Pressostats: RATED (kg/cm2) OFF ON DESCRIPTION UNITS EFFECT RESET Low pressure (LP) 030 to 080 0,5 1,5 Unit stops High pressure (HP) Low ambient control (HPC) 030 to 080 27,5 22 Unit stops on cooling mode Manual (electric) Heat pump units 26,5 22 Outdoor fan stops on heating mode Automatic/ Manual (electric) (1) Automatic (1) For heat pump units, when the unit is working during an hour, the 2 first resets are automatic, the third one is manual (electric). For cooling only units, the reset is always manual (electric). For electrical resets, disconnect power supply from the unit. Indication for pressostat alarms: For heat pump units, the PCB (located at the outdoor unit electrical box) has 2 indicators, HP and LP, which are low pressure and high pressure indicators. If any of those are lighted, indicates that the protection is activated; if any indicator is flashed, indicates that the protection has been reset, and it is waiting for disconnecting power supply. à Probes: • Anti-freeze protection: it comes on through the indoor unit coil probe (ID), avoids ice forms on cooling mode when temperature measures 0ºC, the unit stops. This protection has an automatic reset. • Overload heating mode protection: it comes on through the indoor unit coil probe (ID), avoids the unit works on heating mode with high condenser temperatures, when temperature measures 63ºC, the unit stops. This protection has an automatic reset at the first time, and manual (electric) for the second one. 3.- Defrost cycle: For heat pump units during the heating mode, it is possible the unit goes on to the defrost cycle. During this cycle, it is necessary to melt the ice on the outdoor coil, for that the unit will start working on cooling mode, and outdoor and indoor fans will stop. needed JMP5 JMP6 Function: the defrost cycle is controlled through the PCB (outdoor unit) and the Time for defrost temperature probe (TS) located on the outdoor coil. The defrost cycle begins when 30 min TS< -2ºC during 45 min. (not necessary on and on). This period can be changed 45 min (2) through jumpers JMP5 and JMP6 from PCB. The defrost cycle ends when 60 min TS> +18ºC or because the defrost cycle has exceeded 12 min. 75 min (2) Factory setting 32 4.- MAINTENANCE IMPORTANT: MAKE SURE THE UNIT IS COMPLETELY DISCONNECTED FROM THE POWER SUPPLY WHEN CARRYING OUT ANY TYPE OF WORK ON THE MACHINE. ALL MAINTENANCE SERVICE ON THE UNIT MUST BE CARRIED OUT BY QUALIFIED PEOPLE. ONLY COIL CLEANING AND FILTER REPLACEMENT CAN BE DONE BY NON-QUALIFIED PEOPLE. 4.1.- PREVENTIVE MAINTENANCE PREVENTIVE MAINTENANCE PREVENTS COSTLY REPAIRS. BECAUSE OF THIS, PERIODIC INSPECTIONS ARE REQUIRED: - GENERAL STATE OF THE CASING: Furniture, paint, deterioration due to bumps, rust spots, leveling and supporting, state of the shock absorbers, if installed, screwed panels, etc. - ELECTRICAL CONNECTIONS: State of hoses, tightness of screws, grounding, current draw of the compressor and fans and checking that the unit is receiving the correct voltage. - COOLING CIRCUIT: Check that pressure values are correct and that there are no leaks. Check that there is no damage to the pipe insulation, that the state of the batteries is correct and that there are no chips or clogs retained by the air flow, etc. - COMPRESSOR: Inspect the oil level, if sight glass is present. Inspect the state of the silent block fixtures. - DRAINS: Check that water drains correctly and that the drain trays are clean. - FANS: Check that fans turn freely and in the correct direction without excessive noises. - CONTROL: Check Set Points and normal operation. - AIR FILTER: Detachable for cleaning by sliding front and down side. A) ONE SIDE: filter can be removed sliding it out, from left or right side, as picture shows. B) FRONT SIDE: push air filter up and pull it out, as shown in the picture. The filter should be cleaned with a vacuum cleaner or washed in soapy water. The frequency for cleaning or changing the air filters will depend on the quality air in the area (fumes, vapors, suspended dust particles, etc.). - ACCESS TO INSIDE COMPONENTS: The whole unit will be accessed, without disassembling the ducts, through the cover located at the bottom of the unit. This allows: - To carry out an inspection, checking or replacing any internal component of the unit (motor-fan). - Cleaning the coil and drip tray. LNXO 018-024-030-036-048-060 LNXO 070-080 Drip tray Fan access panel Fan access panel It is very important cleaning the coil and the drip tray periodically. - For models 018 to 060 it is necessary to detach the drip tray to get the coil. This can be easily done by removing the screws which join the drip tray with unit sides. - For models 070 to 080, to get the coil, only have to detach fan access panel. 33 4.- MAINTENANCE 4.2.- CORRECTIVE MAINTENANCE If some component in the cooling circuit must be replaced, follow these recommendations: - Always use original replacement parts. - Remove the entire refrigerant charge from the unit. Create a slight vacuum as a safety measure. - Regulation prohibits the release on the refrigerant into the atmosphere. - If cuts must be made in the pipework, use pipe cutters. Do not use saws or any other tools that produce filings. - All brazing must be carried out in a nitrogen atmosphere to prevent corrosion from forming. Direction of the flame - Use silver alloy brazing rod. Wet rag - Take special care that the flame from the torch is aimed in Silver alloy welding rod the opposite direction from the component to be welded and Nitrogen is covered with a wet rag in order to avoid overheating. Component to be welded - If a compressor must be replaced, disconnect it electrically and un-braze the suction and discharge lines. Remove the securing screws and replace the old compressor with the new one. Check that the new compressor has the correct oil charge, screw it to the base and connect the lines and electrical connections. - Carry out the vacuum above and below until -750 mm Hg is reached. Once this level of vacuum has been reached, keep the pump in operation for at least one hour. DO NOT USE THE COMPRESSOR AS A VACUUM PUMP. - Charge the unit with refrigerant according to the data on the Rating Plate for the unit and check that there are no leaks. 4.3.- FAILURE DIAGNOSIS PROBLEM SOLUTION 1.- Unit does not work. • Check electrical supply of the unit. • Check electrical connection. • Check that remote controller and its parameters work correctly. 2.- The fan of the unit works too fast without any change on speed. • Check that the filter of the unit is clean. • Check electrical connection. • If the problem persists, check the function of the motor. 3.- Noise on pipe system.
