7 INSTALLATION SUGGESTIONS
The fan heaters must be installed in a position where they will heat the room uniformly, on ceilings able to support their weight, at a height in accordance with
the instructions given in section 7.1.
The fan heater is supplied with a black (RAL9005) metal grille pre-assembled to it: the grill should be left installed on the unit as an additional safety unit.
As an alternative to the grill, the fan heater may be fitted (where provided for in the design) with the air diffusers included in the catalogue.
Install any diffusers provided as accessories on the unit before installing it.
Use the eyebolts on the back of the casing to support the fan heater.
Maintain adequate space around the fan heater to allow it to operate correctly and to allow routine and reactive maintenance to be performed (see “overall
dimensions” section).
Install the line circuit-breaker (not provided) in a position where it can easily be reached by the user in case of an emergency stop.
If the system is turned off in the winter, drain off the water to avoid freezing damage; if antifreeze solutions are used, check the freezing point by consulting the
table below.
7.1 INSTALLATION HEIGHTS AND RANGES
To ensure that the fan heaters are positioned correctly in the room requiring heating, tables are provided giving the floor heating zone diameter
according to the installation height and the type of diffuser installed.
This value also depends on the difference (∆Tbs) between the inlet air temperature (Tbs1) and the outlet air temperature (Tbs2).
Tables refer to a ∆Tbs value of 15°C.
For different temperature differentials, multiply the maximum installation height and the airflow zone diameter by coefficients F1.
The air diffusers available as accessories allow rooms to be heated evenly by ensuring uniform distribution of the air jet coming out of the fan heaters.
Three different types are available:
- truncated cone;
- anemometric;
- deflecting fins.
They should be chosen according to the installation height and the floor area that the airflow has to cover.
