4.4. Installing single or multiple modules
MULTIPLE PCH heaters can be assembled in a single air handling or roof-top unit, in order to achieve greater heat output.
The heaters can be assembled in parallel; ventilation can be provided on the right or on the left because the PRH heater uses a
single safety device against air overtemperature, which works both for the right and the left air flow.
When multiple heaters are installed, safety is always ensured by the thermostat provided on each module.
----------------------------------------------------------------------------------
NOTE: Horizontal or vertical positioning refers to the air
flow direction
-----------------------------------------------------------------------------------
Fitting a single heater (A System)
In standard installations with a single heater, the air flow is
horizontal and can have both a right or left direction. The fan
can be fitted upstream or downstream of the heat exchanger.
On request, the air flow can be vertical.
For PCH heaters it is necessary to order the module with code
ending with "-00V0". This specification determines the correct
position and orientation of the condensate drain.
----------------------------------------------------------------------------------
ATTENTION: When the air flow is vertical, PCH heater can
be made horizontal by rotating the standard vertical heat
exchanger by -90° (90° anti-clockwise rotation), as shown
in the picture; it is not possible to apply a rotation in the
opposite direction (90° clockwise rotation).
----------------------------------------------------------------------------------
Fitting multiple heaters in parallel (B System and C System)
When high heat outputs are generated, a solution with two or
more heat exchangers must be used. In this type of installation,
it is necessary to check that the air flow on the heat exchangers
is balanced.
Horizontally combined modules (B System)
In the standard configuration, the air flow going through the
heat exchanger is horizontal, coming either from the right or
from the left.
