1.3 Warranty claims – Exclusion of liability
All versions of this documentation must be observed, otherwise the warranty shall cease to apply. The same applies
to liability claims against Helios. The use of accessory parts, which are not recommended or offered by Helios, is not
permitted. Any possible damages are not covered by the warranty. Changes and modifications to the unit are not
permitted and lead to a loss of conformity, and any warranty and liability shall be excluded in this case.
1.4 Certificates - Guidelines
If the product is installed correctly and used to its intended purpose, it conforms to all applicable provisions and EU
guidelines at its date of manufacture.
1.5 Receipt
The shipment must be checked for damage and correctness immediately upon delivery. If there is any damage,
promptly report the damage with the assistance of the transport company. If complaints are not made within the agreed
period, any claims could be lost.
1.6 Storage
When storing for a prolonged time, the following steps are to be taken to avoid damaging influences: Heater fan pro-
tection by dry, airtight and dust-proof packaging (plastic bag with desiccant and humidity indicators). Vibration-free,
water-tight and constant-temperature storage at a temperature in the range -20 °C to +40 °C.
In case of reshipment (above all, over longer distances; e.g. by sea), it must be checked whether the packaging is
suitable for the form and route of transport. Damages due to improper transportation, storage or putting into operation
are not liable for warranty.

and
STH 15T
are suitable for heating and drying on construc-
tion sites, in production sites, storage sites and workshops, churches and meeting rooms. They are suitable for heating
normal or slightly dusty, non-aggressive and humid air, at normal temperatures and in moderate climates. They comply
with protection class IPX4 (splash water protection).
– Reasonably foreseeable misuse: The space heaters must only be positioned with the specified minimum distance to
the walls. In case of operation in difficult conditions, such as high humidity, long periods of standstill, heavy contamination,
excessive exposure to climatic, technical, electronic influences, consultation and release approval is required, since the
standard series design is not suitable for this.
– Improper, prohibited use: Any use other than the intended normal use is not permitted! The covering of the space heater
during operation is prohibited. The space heaters must not be operated in contact with water or flammable materials,
and outdoor installation is not permitted. Use in explosive environments is also not permitted!
1.9 Performance data
The unit type plate gives an indication of the mandatory electrical values; which must be coordinated with the local
supply network.
