4 SUMMARY In compliance with the current norms, the machine should be installed only by a technical person qualified for this type of work. During installation, ensure that: The machine is moved as given in section 2.1 The required personal protection devices are worn so as to avoid injuries caused by electrical and mechanical hazards (injuries by touching panels, sharp edges, etc.) Electrical connections are made after the power supply has been shut off, in compliance with the recommendations given in session 6 Grounding is carried out in compliance with current standards The machine is powered on when installation has finished (ducting installed and inspection doors closed) 1 Receiving the Equipment The units are delivered on stringers or palettes then wrapped in plastic film. 1.1 Checks on Reception When the equipment is received, the state of the packaging and the equipment must be checked. In the event of damage, make an accurate note of any problems on the carrier s delivery note. 1.2 Unpacking When the equipment is unpacked, check the following: The total number of packages are present All accessories are present (dampers, roof, electric switchgear, etc.). After unpacking the equipment, the waste must be disposed of in compliance with the current standards. No packaging should be discarded into the environment 1.3 Storing The equipment must be stored in shade, in a dry place, at a temperature between -20 C and 40 C. 2 Installation 2.1 Handling The units must only be moved in their installation position. If the device is handled using a fork-lift truck, ensure this supports the load-bearing structure and does not touch the panels enclosing the unit. If the device is moved using a crane, use four cables of identical lengths. These must be at least as long as the greatest distance between two fastening points. If L + W + H > 5m then the case must be lifted using a lifting beam. 2.2 Space required Generally speaking, it is desirable to provide access space of at least the width of the unit on the access side for maintenance. These units require a siphon and must be installed at a sufficient height to allow this to be installed. Note: In case of vertical units, provide at least 300mm on the rear for connecting the condensates. 3

5 2.3 Installation The unit must be laid on a sufficiently rigid and flat surface (use vibration mounts if necessary). For the HVAC connection, select duct sections based on dimensions of the flexible bands that should be properly stretched. Install the unit such that bad weather or ambient temperature cannot damage the internal items of the unit during installation as well as when used later (possibly provide a protective cap) Installation of the Units on the Floor The unit must be laid on a sufficiently rigid and flat surface (use vibration mounts if necessary). For these units, provide a slope of 2 to 3% for the removal of condensates in the direction of the width. (Connect the condensates as per section 2.4) Outdoor Installation of the Units For raising the unit above the ground (protection from water), a set of feet may optionally be supplied (SLK). A roof (WR) as well as grated bevelled nozzles (RCC) or rain cowls (RC) must also be provided if necessary (available as options). For these units, provide a slope of 2 to 3% for the removal of condensates in the direction of the width. (Connect the condensates as per section 2.4) Installation of the Units on the Ceiling 2.4 Siphon The units must be mounted preferably on a frame suspended from the structure of the building, taking care to comply with allowable loads (the frame is the installer s responsibility). For these units, provide a slope of 2 to 3% for the removal of condensates in the direction of the width. (Connect the condensates as per section 2.4). Moreover, the Crown 90-1 to 90-4 units can be suspended directly from the ceiling by means of M8 threaded rods connected to the attachment lugs on the lower part of the units. Before starting the unit, check the tightness of all bolts, particularly those of rotating components. Provide a siphon on each condensate drainage pipe. A siphon can only be used for one drainage system. Note: The siphon must be connected in accordance with Best Practices in order that the condensates are removed as efficiently as possible. The height H must be at least equal to the maximum internal negative pressure of the unit ( p in mm) Example: p = 500 Pa 50 mm CE H > 50 mm 2H > 100 mm 4

15 6.6 Connection of Pressure Transmitters for CAV EC / COP EC / CAV AQ EC The pressure transmitters are factory wired. 6.7 Connection of CO2 Transmitters for VAV AQ EC / CAV AQ EC The CO2 transmitter is factory wired. Crown COP EC / CAV EC CAV AQ EC Pressure Transmitter 6.8 Econological Bypass This function is automatically controlled using the CORRIGO regulator s programming and probes installed as standard within our high efficiency counter-flow Crown units. In winter: When heat is required, the Bypass closes to recover maximum energy through the plate exchanger. If this recovery is not adequate to reach the temperature set-point, the water battery valve will open or the electric battery will start. In summer (FREE COOLING): The Bypass closes when the outside temperature is higher than the inside temperature to prevent the outside heat from entering directly. If the outside temperature is lower than the inside temper ature, the Bypass opens to get the cool outside air. For the Crown 90-6 the single servomotor is wired in the same manner as the small shutter. 14

16 6.9 Night Cooling This function is used during summer to cool the buildings at night by using cool outdoor air. Thus the cooling load to be delivered during the day is reduced. The Night Cooling function works only between midnight and morning 7 a.m. During a Night Cooling period, the heating and cooling outlets are blocked. The Bypass is also open to prevent air from travelling through the exchanger. At the end of a Night Cooling period, the heating is blocked for 60 minutes. Operating Conditions: The outdoor temperature was greater than 22 C during the day The clocks are set either in LS or at stop between midnight and 7 a.m. The outdoor temperature is less than 18 C during the Night Cooling period The outdoor temperature is greater than 10 C during the Night Cooling period The room s ambient temperature is greater than 18 C During the Night Cooling period, the fan runs at 85% capacity. This speed can be adjusted. See section For the COP EC version, a maximum 24V 2A output is provided to you between the DO7 and 2 terminals to force the opening of the dampers during the Night Cooling period Automatic Defrost This function is automatically controlled using the CORRIGO regulator s programming and the probes installed as standard in our double-flow Crown units. Defrosting starts with the opening of the Bypass (defrost temperature (SDG) less than 5 C). If the Bypass function is not adequate to defrost the exchanger (of the outside temperature is less than -10 C) the new air fan modulates its flow-rate until stop and then restarts as soon as the defrost temperature probe becomes greater than 5 C. For the e 3 lite version: a defrost battery is installed on the new air. This regulates the exchanger s incoming temperature at 1 5 C. This shall eliminate any risk of frost while keeping the Bypass as closed as possible. Thus, maximum efficiency of the system is maintained Hot Water and Cold Water Battery (the valve should be connected in off position) In e 3 nhanced BC and e 3 lite BC version, the hot water battery is already installed in the unit. The Anti-frost Thermostat is connected. However, you should wire the 3-way valve. For all other versions, also connect the THA (Anti-frost Thermostat) and shift the supply air probe after the battery. Connect the 3-way valve s servomotor as follows: Hot Battery: Terminal 20 of the Crown unit to the +24V (G) of the valve s servomotor Terminal 21 of the Crown unit to the 0V (G0) of the valve s servomotor Terminal 22 of the Crown unit to the 10V (Y) of the valve s servomotor Connect NF contact (C and 2) of the THA (Anti-frost Thermostat) to 18 and 19 Cold Battery: Terminal 26 of the Crown unit to the +24V (G) of the valve s servomotor Terminal 27 of the Crown unit to the 0V (G0) of the valve s servomotor Terminal 28 of the Crown unit to the 10V (Y) of the valve s servomotor Connect NF contact (C and 2) of the THA (Anti-frost Thermostat) to 18 and 19 15

17 6.12 Changeover Battery (only in e 3 ssential version) (the valve should be connected in off position) A changeover battery can be installed in e 3 ssential version. In this case you will not be able to add another battery (hot water or cold water battery). You should connect the 3-way valve, the changeover handle, the THA (Anti-frost Thermostat) and shift the supply air probe after the battery. Connect the assembly as follows: Red wire of the handle (CO) on Y of the valve s servomotor Terminal 20 of the Crown unit to the +24V (G) of the valve s servomotor Terminal 21 of the Crown unit to the 0V (G0) of the valve s servomotor Terminal 22 of the Crown unit to the brown wire of the handle at the hot signal Terminal 28 of the Crown unit to the black wire of the handle at the cold signal Connect NF contact (C and 2) of the THA (Anti-frost Thermostat) to 18 and Direct Expansion Battery (this function should be mentioned on ordering) A maximum 24V 2A output is provided to control the start stop of your cold unit to be connected between terminals DO7 and 2 (provide a relay on the condensation unit). You should also shift the supply air probe after the direct expansion battery Electric Battery Associated with a Crown e 3 ssential (should be specified with the order) Possibility of adding an electric battery in duct at the Crown e 3 ssential unit. In this case we provide you with a heating signal 0-10V (terminal 21-22) as well as the terminals to bring your safety thermostat s NF contact (break contact by temperature rise). If the Crown unit is linked to an electric battery provided with a CAB-CBE (electric battery housing), follow the diagram as given below. CAB-CBE Terminals Crown Terminals 16

The control is also connected. 17

19 6.17 Repeater (see section for the configuration) If you would like to have remote control in addition to the display, you must use a repeater. In this case you can move the remote control system up to 1 km away. Use a shielded twisted 2-pair cable of BELDEN 8723 type or equivalent to connect the repeater to the control housing and a standard cable (2x0.5 min. to 2x1.5 max.) for the 24V. You can connect up to 6 housings to the same repeater. Cannot be linked to a MODBUS communication but can be linked to a LON communication. Connect the wires as follows: B of the repeater to the B terminal of the Crown unit (wire of the shielded cable as given in the diagram below) A of the repeater to the A terminal of the Crown unit (wire of the shielded cable as given in the diagram below) N of the repeater to the N terminal of the Crown unit (shielding of the shielded cable as given in the diagram below) G of the repeater to terminal 7 of the Crown unit G0 of the repeater to terminal 8 of the Crown unit 7 Setting 7.1 Control (on CORRIGO or remote control) The monitor has four rows with 20 characters.

32 8.2 Change the Battery This operation requires good knowledge about the DES (electrostatic discharges and wearing a bracelet or any other earthing accessory. When the Low battery alarm appears and the red indicator lights up, this means that the emergency battery for memory and real-time clock back-up is too weak. The procedure for changing the battery is described below. A condenser is used to back-up the memory and to operate the clock for about 10 minutes after the current has been dut. If the battery change operation takes less than 10 minutes, there is no need to reload the schedule and the clock continues to function normally. The spare battery is of CR2032 type. Press on the clips on each side of the box with a small screwdriver to detach the base cover. Hold the base and remove the cover. Battery Location: Take the battery and slowly pull upwards until the battery has been removed from its housing. Take a new battery and slide it in the housing. Take care to fit the battery in the correct direction to match with the polarity. 31
