(fig. 9). - Check the module assembly order on the TCF working drawing. - Remove the material required for assembly, supplied on delivery, from the container located inside one of the inspection doors.
CONNECTION TO SYSTEMS AND START-UP To allow easy extraction of the exchanger during maintenance: 4.1. CONNECTION TO DUCTS - the connections to the mains must be made in such a way as to allow removal of the exchanger At the points of connection to the air ducts, the Air - ON-OFF VALVES must be installed to exclude the heat Treatment Units have a smooth or a flanged surface.
The diagram (Hg. 15) shows the "standard" installation of Special care must be taken with the SIPHONING of these a water-type heat exchanger. exchangers to ensure the maximum heat exchange and correct entrainment of the oil in the circuit. The diagram in fig.
TCF installs steam batteries with angled or vertical pipes (fig. 19) to ensure correct drainage of the condensate and prevent it from accumulating inside the system. In Air Treatment Units with this type of exchanger special care must be taken to ensure that the base is level (see section 3.3.2.).
The humidification and cooling exchanger sections of the TCF Units are fitted with a threaded drain pipe projecting laterally about 80 mm. To avoid damaging the pump at first-time start-up, check...
In this way the non-reconditionable filtration sections will be preserved. On request, TCF supplies differential analogue pressure gauges (fig. 25) or oil-column, gauges (fig. 26) of the types shown. Fig. 25...
Before start-up: starting. - Inspect the motor control board and check that the For this purpose TCF installs dual voltage 380/660 V motor protection devices are sized for the maximum motors on its Air Treatment Units starting from an output amperage.
The diagram in fig. 29 shows the connection of a TWO- SPEED MOTOR with two separate windings to the power supply. TCF installs motors of this kind on its Units: - 220/380 V for power ratings up to 5.5 kW - 380/660 V for power ratings over 7.5 kW.
4.6.3. Drive Before starting the Air Treatment Unit, check: - the tension of the “V“ belts (section 5.5.4.) - that the pulleys are aligned (section 5.5.4.) - that the dowels, shown in fig. 32 in their possible installation positions, are doing their job of securing the pulleys to the hubs.
INSPECTION To make this check you must first take pressure readings at the PRESSURE POINTS in front of and behind each 5.1. PRELIMINARY CHECKS filtration section (on request, TCF can provide the relevant attachments during manufacture) DELIVERY OUTLET HYDRAULIC - Compare the flow rate value obtained as described CONNECTIONS must be completed.

50°C. Do not use solvents or caustic soda. Let the diaphragm dry by evaporation and refit it only when it is perfectly dry. TCF advises you to CHECK THE CONDITION OF THE FILTERS ON A WEEKLY BASIS. THE PREFILTERS MUST BE RECONDITIONED EVERY 7- 20 DAYS depending on the type of environment being conditioned.
6.2.3. Rotary filters 6.2.4. Reconditionable bag filters The rotary filters installed in the TCF Air Treatment Units These are non-rigid filters with EU3-EU4 efficiency THEY come complete with control board and differential CAN BE RECONDITIONED using two different methods. pressure switch.
- In the case of prolonged idleness of the heat exchanger deodorised. In order to maintain efficient deodorisation, circuits, they should be completed drained TCF recommends that the filters be replaced every 30-40 - Where an anti-freeze system based on heating elements days.
With regard to general maintenance operations, follow the steps described in 6.3.1. TCF recommends you check, on at least a weekly basis, that there are no gas leaks from the distribution heads. In the event of gas leaks, the COOLING CHARGE would be lost and the whole system compromised.
The fans mounted on the damaged part(s) the TCF Units are fitted either with oilless bearings - Perfect alignment of the drive (design life 2000 hours) or pedestal bearings. depending - Belt tension (see section 6.5.4.).
- check the condensate drain every month and remove any deposits. 6.6.2. Rotary recuperator The heat exchange surface is self-cleaning. However, TCF recommends: - removing any residue with a compressed ai rjet or steam 6.5.3.2.
