GENERAL DESCRIPTION CWC 00 (030-040-050-070-090) X Y Model Chilled Water Cassette Models 600x600: 00-030-040-050 Models 600x00: 070-090 Close cooling capacity in W x 00 : Plastic diffuser : Metallic diffuser : Pipes units 4: 4 Pipes units The CEILING CASSETTES are designed to operate with chilled and hot water. They provide both cooling and dehumidification in cooling mode and heating in the latter, cleaning and filtering the air in the process. Electrical heating elements are available as an option on some units. The units are available with cooling capacities from 950 to 8450 W and heating capacities from 400 to 0600 W. CABINET The unit chassis is made of galvanised steel and is fully insulated inside. The units have been designed in order to install them in high ceilings where standard plates 600x600 mm or 600x00 mm will be used. DIFFUSER PANEL Two alternatives can be chosen: - Plastic diffuser: Made in decorative plastic, with a smooth finish. Internal insulation prevents condensation from forming. 4 louvres for MODELS 600x600 and 6 louvres for MODELS 600x00 ensure air distribution. - Metallic diffuser. HEAT EXCHANGER Made of copper tubes and aluminium fins. Coils have been designed and manufactured to ensure maximum efficiency. FAN The units are supplied with one (models 600x600) or two (models 600x00) 3-speed centrifugal fans. The impeller blades have been designed specifically for this type of units ensuring exceptionally low sound levels and the motor is protected with internal thermal protection. AIR DISTRIBUTION The position of the louvres can be adjusted manually (only for plastic diffuser). AIR FILTER A polypropylene washable air filter is incorporated in the unit; it is easily accessible for maintenance. INTERNAL COMPONENTS The unit is designed with serviceability in mind, and all components are easily accessible. A drip tray collects condensate which is removed by means of a condensate pump. ELECTRIC CIRCUIT The electrical panel is provided with a terminal block which provides connection to mains power or to a control box (depending on model). A fused isolator is not included and where required shall be installed by others. OPTIONS Electric heater (depending on model). Fresh air kit. - Duct connection. - Fresh air fan. - Duct supports. Air supply to an adjacent room kit. - Duct connection. - Duct supports. Water control valve kit with way or 3 way proportional control valves. Auxiliary drip tray. Thermostat. Float switch. Master Slave. Fitting & testing valves. Water evacuation security.

One to connect a fresh air inlet duct, and another to connect an air distribution duct to deliver air to an adjacent room. FRESH AIR MAKE UP (FIG. 5) INSTALLATION Remove the 68 mm insulation material and cut out the prepunched side knockouts. Secure the duct connection flange to the unit. Conducts can be of flexible polyester type or corrugate aluminium, externally covered with anticorrosion material. Install a supplementary fresh air fan for the introduction of fresh air into the unit. The fan motor must be controlled by an ON-OFF switch. Fresh air flow must be less than 0% of the total air flow, to avoid operating problems. A speed controller should be installed in the supplementary fan motor, for adjusting the air flow. AIR SUPPLY TO AN ADJACENT ROOM (FIG. 6) INSTALLATION Remove the 50 mm insulation material and cut out the prepunched side knockouts. For models 600x600, the two prepunched side knockouts must not be used at the same time to provide conditioned air to an adjacent room. For models 600x00, do not use the same fan to provide air conditioned to both ducts. Cut away the polystyrene around the inside edge of the opened panel, remove the polystyrene. Use a duct connection flange and a suitable duct. Air supply to an adjacent room requires that outlet corresponding with the duct is closed. An air inlet grille must be fitted (if possible near the floor) between the air conditioned room (where the unit is situated) and the adjacent room. Conducts can be of flexible polyester type or corrugate aluminium, externally covered with anticorrosion material. The duct length can be calculated by taking into account the pressure drop through the unit, using the following table: Air flow supplied to an adjacent room in, fresh air fan at high speed: UNIT/MODELS Air flow Available pressure Pa CWC 00-030 P CWC 00-030 4P 75 00 5 0 8 5 CWC 040 P CWC 040 4P 00 00 5 0 0 0 CWC 050 P CWC 050 4P 50 5 5 0 0 30 CWC 070 P CWC 070 4P 400 00 50 0 0 0 CWC 090 P CWC 090 4P 500 50 50 0 0 30 600x600 Duct connection Ø75 mm (*) Duct Ø5mm FIG. 5 Air inlet grille and filter Reduction 5-75mm (*) Fan (*) Air intake 600x00 Duct Ø5mm Duct Ø50mm Duct connection Ø75 mm (*) Reduction 5-75mm (*) Conic tapping 50x5 (*) Fan (*) Air inlet grille and filter Air intake 600x600 Duct connection Ø50mm flange and clip (*) FIG. 6 (*) Elements included in optional kit Insulated flexible duct Ø50 Grille 600x00 Duct connection Ø50mm flange and clip (*) Grille Insulated flexible duct Ø50 9

UNIT INSTALLATION 6. For Models 600x600, to facilitate the connections of water pipes and the drain tube, is advisable to disassemble the supporting bracket situated on this corner. Once the installation is completed, the bracket must be reassembled. 7. When lifting the cassette into position care should be taken not to lift the unit by the drip tray, water connection or drain tube; these elements could be damaged. The cassette should be lifted by the hanging brackets. The hanging brackets should be insulated with the supplied insulation. 8. The cassette brackets hook over the washer. Tighten the cassette with the lower nuts. MODEL 600x600 MODEL 600x00 9. Check to ensure the unit is level. The drain will then automatically be lower than the rest of the drip tray. 0.

MAINTENANCE WARNING: Electric shock hazard can cause injury or death. Before attempting to perform any service or maintenance on the unit, turn OFF the electrical power, and check that the fan has stopped. ALWAYS INSTALL THE FILTER If the unit operates without the filter, there is a risk of damaging the unit through dust contamination. CLEANING THE AIR FILTER PLASTIC DIFFUSER PANEL.- Stop the unit..- Open the air intake grille on the unit. Open the grille by way of two hand triggers. The grille will swing down supported by the stays and the hooks. 3.- Release the air intake grille from de unit. To release the grille pull it down until the stays can be unlock from the diffuser, then pull it back to an angle greater of 90º and lift it lightly, finally the grille hooks will come away from the diffuser. 4.- Remove the air filter once the air intake grille has been released Clean the air filter depending on the operation conditions and working time, (approximately once every 6 months). Use a vacuum cleaner to clean dust off. If the filter is too dirty, wash it with water and neutral detergent. Dry the filter before re-fitting. 5.- Replace the filter in the right position. 6.- Close the air intake grille. MODEL 600x00 Place the hand triggers on position again.

MAINTENANCE WARNING: Electric shock hazard can cause injury or death. Before attempting to perform any service or maintenance on the unit, turn OFF the electrical power, and check that the fan has stopped. ACCESS TO INTERNAL COMPONENTS When checking or replacing any internal component of the unit, e.g. coil, fan motor, condensate pump, float switch, the drip tray and volute must be removed. DISASSEMBLING DRIP TRAY Remove the air intake grille and filter. Disassemble the diffuser panel by removing the screws that attach it to the unit. Detach the volute/s by removing the screws, and the electrical panel cover/s. The drip tray can be taken apart by removing its screws, as shown in the figure.

In cooling operation the louvres are positioned to distribute air outwards from the discharge, which allow airflow close to the ceiling. Louvre position for correct air flow in heating mode. Louvre position for correct air flow in cooling mode. In heating mode the louvres are repositioned to blow air in a downward direction. The air should flow towards to the floor to prevent layers or stationary hot air forming in the upper part of the room. When the electro-mechanical thermostat is used, the louvres movement is manual, louvres should be positioned manually. FAULT ANALYSIS PROBLEM.- Unit not operating..- Indoor unit fan running too fast without apparent speed change. 3.- Condensate overflowing. ACTION Check power is available at unit. Check wiring. Check remote control is functioning and set properly (if any). Check the indoor unit filter is clean. Check wiring. If problem persists then motor may be faulty. Check drip tray for blockage, and condensate drains away. Check unit is level. Check condensate pump is working. Check service drain pipework. 0
