EOS Cubo / Cubo Avantgarde - Installation and Operating Instructions EN-25
Installation
3.1.3 Air inlets and outlets
At least one air inlet must be installed in the cabin to ensure a sufficient air
flow in the cabin and to prevent the heater from overheating.
The required size of the air inlet depends on the heater power; see
2.4 Technical data, EN-17.
WARNING
Fire hazard from overheating
The heater can overheat if the air supply is insufficient. There is a
risk of death due to fire.
Ensure that the air inlets and outlets provide sufficient ventila-
tion. Install a fan if necessary.
Start the sauna only after all air inlets and outlets have been
opened.
If the heat-up process takes a long time, the underlying reason can be that
the heater has an insufficient fresh air supply. The sauna cabin air exchange
rate must be at least 5 times per hour.
If, despite compliance with dimensions, there is still not enough fresh air to
reach the heater, a fan must be installed at the opening outside of the
cabin.
3.1.4 Connecting cable
The heater is connected to the sauna control unit via a connecting cable.
This temperature-resistant silicone cable is very pressure sensitive and
must be protected from damage during installation. To do this, route a
cable duct or empty pipes from the heater’s installation site to the relay
box. The radius for laying the cables around a corner must equal a mini-
mum of 100 mm/3.93701 in.
See the connection diagrams in 4.2 Connections, EN-32.
