Esempio 3

A 90° plenum (RAM) may be used instead of the air delivery union for better direction of airflow. Insert the manual air intake section (SSP) in the air filter section (SFA) by means of the male-female coupling. After having secured it with the self-tapping screws (4.2 x 9.5 galvanised), anchor it to the ceiling as illustrated for the base unit in figures 4-7. Put another connecting flange on the vibration isolation joint (GAM) and secure it using cheese-headed screws M8x16 and hexagon bolts.Insert the straight delivery plenum (PAM) in the connecting flange and fix it using galvanised self-tapping screws 4.2 x 9.5. Then connect the 90° plenum (RAM) with the procedure described above.

Esempio 4

La sezione di riscaldamento con resistenza elettrica (SRE) viene di solito posizionata in mandata prima del plenumdritto di mandata (PAM). Può essere utilizzata indifferentemente con il bocchettone di mandata (BAM) o con il plenum a 90° di mandata (RAM).

INSTALLATION/USE/MAINTENANCE GUIDE

OUT

CAUTION! Always use a wrench and counter-wrench for connection

of the coil to the pipes (fig. 11).

CAUTION! If the valve is installed, suitably insulate the valve body with insulating

material (fig. 12).

Connect the water inlet and outlet pipes, observing the indications given on the side of the unit. Correctly insulate the water supply pipes to prevent dripping during the cooling mode of operation. A shutoff valve should be inserted on the water supply pipe and a balancing valve on the outlet pipe. The valve body and balancing valve should also be properly insulated to prevent dripping. It is the installer's responsibility to insulate properly and the manufacturer cannot be held liable for any insulation work.

N.B.: It is always advisable to install the valve.

the valve reduces consumption because upon reaching the set temperature the circulation of water is stopped to avoid wasting energy (the fan coil would otherwise continue to heat like a radiator, even with the motor at a standstill). In the cooling

mode of operation the valve stops the circulation of water when the set temperature is reached, this stopping the internal exchanger from continuing to condense water with possible undesirable dripping onto the floor. It also reduces chiller operation with consequent energy saving.

In the heating mode of operation

CONDENSATE WATER DRAINAGE

Fig. 13

3 cm/m

The condensate drain pipe should slope downwards by at least 3 cm/m and should not have ascending or throttled sections in order to ensure a regular flow of water. It is advisable for a trap to be fitted. The condensate drain pipe should be connected to a rainwater drainage system. Do not use sewage systems to avoid possible rising of odours in the event of evaporation of the water in the trap. Upon completion of work, check that the condensate flows out properly by pouring water into the tray. The condensate water drainage system should be fabricated in a workmanlike manner and should be periodically checked.

The manufacturer cannot be held liable for any damage caused by dripping in the absence of a valve or of periodic maintenance of the drainage system.

ELECTRICAL CONNECTIONS

RECOMMENDATIONS

Before carrying out electrical connections, ensure that the electricity supply to the supply line has been cut off, checking that the on-off switch is in the OFF position.

- Only qualified electricians should carry out the electrical connections.

- Check that the mains supply is single-phase 230 Vac/1/50 Hz (± 10%).

- Operating the unit with voltages outside the above limits could cause malfunction and renders the warranty null and void.

- The power supply line should be fitted with at least a switch isolator in conformity with European standard EN60947-3.

- Make sure that the electrical system is suitable for providing not only the working current required by the unit, but also the necessary current for powering household and other electrical appliances already in use. Any electrical and mechanical alterations or tampering render the warranty null and void.

The cables should be sufficiently long so that they are not permanently taut or create throttling or compression on metal parts.

The power cables should be sufficiently long so that in the event of accidental tugging the active wires are subjected to stress before the earth wire. Connect the earth wire to the relative terminal marked with the symbol the safety regulations in force in the country of installation.

CONNECTIONS TO THE TERMINAL BOARDS

The electrical connections should be made to the terminal boards on the side of the appliance. Each terminal is identified by the label to be found on the terminal boards.

CAUTION! FAILURE TO COMPLY WITH THE INDICATED CONNECTIONS

MAY CAUSE MOTOR BURNOUT!

TURNING THE COIL

CAUTION

The fan wheels may reach the speed of 1,000 rpm. Do not insert objects into the electric fan and certainly not hands. The motor becomes hot during operation; wait for it to cool before touching it. During the heating mode of operation the exchanger and the connecting pipes may become very hot (80°C). Wait for the exchanger to cool before touching it or protect hands with suitable gloves. The heat exchange water coils are suitable for working up to a maximum pressure of 8 bar. To turn the coil, proceed as follows:

1. Disconnect the terminal board (6) from the side of the unit.

2. Remove the condensate collecting tray (2).

3. Remove the coil fixing screws (5).

4. Take out the coil (3), being careful not to be cut by the fins and not to damage them.

5. Remove the knockouts (1) on the opposite side of the unit (using a screwdriver) to allow the coil connections to pass through.

6. Position the coil, turning it without tipping it upside down, so that the fittings are in line with the holes left by the knockouts.

7. Fix the coil using the previously removed screws (5).

8. Shift the terminal board (fixing it to the side opposite the water fittings) and the motor cables, fixing them with their clamps. Ensure that the cables pass through the hole in the side of the unit, protecting them with the relative grommet. If it proves easier to carry out this operation by separating the wires from the terminal board, mark the positions of the wires to avoid making mistakes when reconnecting.

9. Reconnect the wires to the relative terminal board (6), taking care that they are correctly positioned.

10. Replace the condensate collecting tray (2).
