DISCHARGE (AND INTAKE) PLENUM

The discharge and intake plenum are supplied when the incoming or outgoing airflow must be directed to or from the
bottom of the unit. It has a flange for connection to the basic unit or other accessories and blanked panels for optimum and
flexible use.

DISCHARGE PLENUM FOR ROUND DUCTING

The discharge plenum for round ducting enables the air to be distributed through flexible ducts. Distribution takes place
through two 190mm diameter ducts in sizes FDHD-18, three 190 mm diameter ducts in sizes FDHD-24/30/36, four 250 mm
diameter ducts in sizes FDHD-40/48, three 300 mm diameter ducts in sizes FDHD-75; four 300 mm diameter ducts in size
FDHD-100. The number of ducts is calculated so as to obtain an air speed of 5.0 m/s in the ducts with rated airflow and the
ducts fully open.

AUXILIARY 1 ROW or 2 ROWS HEATING COIL MODULE FOR 4-PIPE SYSTEM

Install the auxiliary 1 row or 2 rows heating coil module to the unit with 8 screws as shown above.

ELECTRICAL HEATER MODULE

The electric heater module is supplied for winter heating as an alternative to the auxiliary hot water coil.
The maximum outputs available with 380V~50 are 3.0 KW for sizes FDHD-18; 4.5 kW for sizes FDHD-24/30/36; 6.0 kW for
sizes FDHD-48/60; 7.5 kW for sizes FDHD-75 and 9.0 kW for sizes FDHD-100. The module must be installed downstream of
the basic unit directly in the outflow of air. The stainless-steel spiral heaters are mounted on a removable frame independent
from the module. The heaters feature ON-OFF operation.

Install the electrical heater module to the unit with 8 screws as same as the auxiliary coil module for 4 pipe systems.

Note:

For correct operation of the heaters, make sure airflow is not less than the values for minimum speed.
