3.1 General
• We wish to emphasize that only qualified fitters or con-
tractors shall install the air heater.
• The installation shall be done in accordance with the
latest issue of all local standards as well as the installation
manual of the device concerned.
• Ensure that the conditions of local utility provision (electri-
cal supply) match the device settings before installing the
device or making it operational.
3.1.1 Transport damage
Please check the air heater for transport damage upon delivery.
If damage is observed, this shall be mentioned on the waybill
and you shall advise your supplier thereof in writing.
3.1.2 Packaging
The air heaters are always packaged in a box made from
recycled paper. We ask you not to earmark the paper for waste
disposal, but for further recycling.
3.1.3 Location
• Adhere to the following guidelines when selecting a loca-
tion for the device:
• place the unit in a central position in relation to the ducting
system;
• place the unit on a flat and solid surface;
• if installation surface is wet, then raise the unit;
• Always place the device in such a way that it is insulated
from the construction–building structure to avoid the
transmission of noise and vibrations.
Attention:
IThe unit must be installed level!
IThe device must be installed in a frost free location. If
impossible, please add a suitable anti-freeze to the hy-
draulic system as to protect the heat exchanger from frost
damage.
IIf a return air is inspired in the combustion compartment,
then under no condition devices with an open combustion
circuit may be present in the installation area!
3.1.4 Minimal clearance
When installing please provide minimal clearance around the
unit:
• keep 50 mm clearance around the sides of the unit;
• keep a minimum of 50 mm between hot water supply and
any flammables..
• At the front of the device there shall be at least 720 mm of
free service space (ensure a comfortable standing height).
3.1.5 Transport on site
Never move the air heaters by tilting them on their angles,
as this may irrevocably damage the device encasing. Such
damage is not covered by the device’s warranty.
4 Installation
3.2 Electrical installation
The electrical installation shall always be performed according
to the latest issue of the relevant standards and the prescripti-
ons of the local energy provider (utility).
IMind your safety: always ground the unit.
3.2.1 Electrical connections
In the casing dierent cut-outs are provided to run cables
through. The PCB features a the mains power 230V~AC (mar-
ked L, N and GND). Connect with a cable to a 230V~AC power
supply. A seperate earthing plug is provided next to the PCB.
We recommend that the machine should be directly connected
to a switchboard with 16A fuses.
3.2.2 Thermostat
The device works perfectly together with the Honeywell
electronic programmable thermostat Vision thermostat. This
thermostat is suited for heating, ventilation and cooling, and
has been specifically designed for use with warm air systems.
Connect the thermostat as per the instructions on the wiring
diagram.
Attention: mind the connections. (See chapter electrical
wiring)
Mount the room thermostat at an approximate height of 1.6 m,
in a central position in the living room and readily accessible to
the normal air circulation in the room.
Always mount the thermostat on an inner wall shielded from
the eects of other heat sources including exhaust grilles, po-
wered devices, direct sunlight, etc. Accordingly, we also do not
recommend placement near windows, outer walls (<1.20 m) or
in the vicinity of stairs. For additional information on assembly
and programming we refer to the thermostat manual.
