Pull the heating wire
(6)
in the condensate pan until it is
in the elbow

(4)
and adaptor
(2)
to the seal
(5)
and secure them both using a cable tie
(3)
.
4.
Connect a condensate drain pipe to the elbow.
5.
Install the heating wire in the condensate drain pipe
(1)
in order to prevent the condensate from freezing in the
line.
6.
Connect the adaptor
(2)
with the product's floor plate
and secure it with a 1/4 rotation.
7.
Make sure that the condensate drain pipe ends in a
gravel bed.
Note
The condensate drain pipe must not be
longer than 365 mm, otherwise it may freeze
over.

Danger!
Risk of death from electric shock as a res-
ult of an improper electrical connection!
An improper electrical connection may neg-
atively affect the operational safety of the
product and result in material damage or per-
sonal injury.
▶
The electrical installation must be carried
out by a suitably qualified competent per-
son who is responsible for complying with
the existing standards and directives.
1.
Only strip a maximum of 3 cm from the outer sheathing
of the flexible lines.
2.
Secure the conductors in the connection terminals.
5.4.1
Establishing the power supply
The external mains connection cable must be earthed and
connected with the correct polarity and in accordance with
the valid regulations.
▶
Check that the mains connection cable is connected cor-
rectly.
The cables that connect the product to the fuse box must:
–
Be suitable for fixed installation,
–
Be weatherproof,
–
Be equipped with a wire cross-section that is necessary
for the product performance.
▶
Connect the product using a fixed connection and a parti-
tion with a contact opening of at least 3 mm (e.g. fuses or
power switches).
In order to meet the overvoltage category II requirements,
further fuse protection may be required.
To meet the overvoltage category III conditions, the parti-
tions must ensure a complete separation of the power sup-
ply.
