PLEASE STORE THESE INSTRUCTIONS IN A SAFE PLACE.
Important safety information
The air inlet and outlet guards must not be covered or
blocked.
Before performing maintenance work on the device, discon-
nect it from the power supply.
THE DEVICE MUST BE GROUNDED.
The heater must not be installed directly below a permanently
installed socket. Combustible materials or liquids and other
highly flammable furnishings must be kept away from the
heater.
For the necessary minimum distances (in mm), see fig. 4.
Install the device such that it is not possible for someone in
the bath or shower to touch the control elements.
The heater must not be operated in very dusty areas.
This device is not suitable for children or persons who cannot
use the device safely as a result of physical or mental disability
or reduced perception without the assistance or supervision
of another person. Children should be supervised to ensure
they do not play with the device.
A warning symbol is attached to the heater. This in-
dicates that the device must not be covered.
The operating instructions belong to the device and
must be stored in a safe place. If the owner changes, the op-
erating instructions should be passed on to the new owner.
IMPORTANT – If the mains cable of the device is damaged, it
must be replaced by the manufacturer, a customer service
representative or a similarly qualified person.
Always ensure proper operation.
Device description
The SmartRad model is a fan convector for heating living spaces.
The fan convector is intended for connection to a central heat-
ing system. The fan convector is suitable for use in heat pump
systems, but it can also be operated in conjunction with other
heating systems, e.g. with oil or gas fires. The device draws in air
from the underside. This is heated up in the heat exchanger and
discharged at the top.

(b) Control panel
(c) Air outlet guard
(d) 1 m connection cable
Fan convectors may only be used in central heating systems
with a closed control circuit.
The heating system must be operated as a dual-pipe system.
The devices must be of a sufficient rating such that they can
compensate for heat losses in the room.

Installation preparation
Remove packaging material.
Unscrew the four fixing screws from underside of device (see
fig. 2) to remove casing cover. Store casing cover such that it
cannot be damaged during installation.
Fixing to the wall
For drywalls, use suitable fixing material (not supplied)!
Draw and drill four holes on a sturdy wall as shown in fig. 4. All
dimensions are in mm.
Insert dowels and pre-fit the two top screws (don't completely
screw in yet).
Hang device on the two top screws.
Insert and tighten the two bottom screws, then tighten the two
top screws.
Hydraulic connection
To ensure a sufficient heating water flow rate through the fan
convectors, observe the following points:
- The devices are not suitable for installation in single-pipe
systems.
- The nominal width of the connection pipe must have a
minimum diameter of 15 mm.
- If the devices are installed in a heating system with various
heat distribution systems (e.g. underfloor heating), a sepa-
rate circuit is required to guarantee a sufficient water flow
rate.
- For optimum operation (heat output) of the fan convectors,
