11 - TECHNICAL SPECIFICATIONS Filter fouling is measured by a pressure sensor located in the electrics box. It is set to 1.5 times the value for the filter when clean (pressure ports upstream and downstream of the filter). 11.1.5 - Standard control elements: (Factory cables) - An intake temperature sensor. - A differential pressure sensor: attached to the electrics box, this allows the difference in pressure upstream and downstream of the filter to be measured, so as to determine whether the filter is fouled. - A water leak sensor: this is found at the end of a wound cable located at the bottom of the unit so that it is long enough to extend downwards into a raised floor, if required, and to be positioned in the area to be monitored. It can be added on request. - Page 16 11 - TECHNICAL SPECIFICATIONS 11.2.2 - Electric heater Operates in two on/off stages or with TRIAC (modulating). The latter allows the power of the electric heater to be varied to ensure it is as close as possible to the required heating capacity. The connection is carried out in the factory. The electric heater is equipped with two safety thermostats, one with automatic reset and the other with manual reset.

Ø 10 mm (3/8") (not supplied by CARRIER) to the pump discharge. For OVER models (3 and 5), if using a spreader beam and slings, the PVC tube will not be directly connected to the pump, for handling reasons. It must therefore be angled in the right direction and fixed to the clamp, as shown below. Clamp Elbow PVC tube...

Double-deflection grids Proposed when air is to be distributed directly into a space. It is mounted on top of the unit and features double-deflection grids (one on each side and on the front) to allow the direction of the air stream to be adjusted manually. The plenum may also be used mounted at the bottom (UNDER) to carry air directly from a space back to the air handling system.
- Page 20 11 - TECHNICAL SPECIFICATIONS This accessory should not be installed in corrosive environments (saline environments) or explosive environments (ATEX area). Composition: This is a mixing box made up of two dampers. (one fresh air side and the other on the room's return air side). Two combined temperature and humidity sensors are also provided at the back of the unit.

• Check the power supply voltage and heat protection rating in accordance with the currents for the various components. • Check the siphon height. • Vent the air out of the coils via the air bleed valves. • Check the tightness of the circuits; retighten the valve if necessary. • To configure the setpoints, please refer to the control manual. "CARRIER CCU Controller" • Depending on the solution chosen, the air flow may be. • adjusted based on the difference with the setpoint. • constant. -

Page 25: Filters
13 - MAINTENANCE 13.1 - Filters Check the filters frequently when commissioning the unit. The rate at which they will clog will depend on how well the air circuits were cleaned. Frequency of servicing The filter life depends essentially on the amount of dust in the air and the efficiency of the filtration system. The filtration quality cannot be maintained if the filter medium has been damaged during maintenance. We recommend that the filters be replaced once every two years, even in case of low to moderate use. Replacing the filter elements When performing maintenance, it is important to avoid releasing and spreading the dust that has accumulated in the filter. Turn off the unit. Access the filters by opening the doors on the front. For filters for sizes W40 to W100 Replace the used filters by new filters. Take care to note the direction of air flow indicated on the new filters. Always make sure that the filter elements are properly positioned before compressing them or turning the unit back on. Runner Thumbwheel - Unscrew the thumbwheel to free the runner. - Remove the runner to take the filters out. -
Page 26: Cooling Coil
13 - MAINTENANCE For filters for sizes W115 - - Unscrew the clamps on the bottom part of the filter (close-up A) - Release the filter by pulling up the tab on the top part of the filter (close-up B) Replace the used filters by new filters. Take care to note the direction of air flow indicated on the new filters. Always make sure that the filter elements are properly positioned before compressing them or switching the unit back on Detail B Detail A 13.2 - Cooling coil Frequency of servicing As the cooling coil is protected by a filter, its air circuits require very little maintenance Always cut the power supply to the unit before any cleaning operations. 13.3 - Electric heater Frequency of servicing The electric heater requires very little maintenance. -
Page 27: Humidifier
13 - MAINTENANCE Cleaning procedure: Remove the filters as instructed above, To avoid damaging the blower nozzle, make sure that it is not too close to the finned surface. 13.4 - Humidifier Servicing Clean the humidifier once a year and replace its tank. Cleaning or replacing the steam tank This operation is necessary when the deposits that form on the active surface of the electrodes prevent the correct flow of current (alarms E08, E06). To remove the tank: Completely drain the tank using the manual drain program governed by the controller. (See extract from the controller manual) Cut the power to the unit by turning it off at the switch or removing the fuses on the line. -
