3. Installation of heating units in the working position
3.1. General information, recommendations and safety during installation of the Atacama heating unit
3.1.1. Electrical safety before assembling the unit
- Before starting any assembly works, it is necessary to switch off the power supply to the prepared
electrical installation for subsequent activation of the unit. During installation, the switch must be
secured against being switched on again.
3.1.2. Modification of existing heating distribution systems
- It is appropriate to use filters for rough impurities in the heating systems to protect the water exchanger
from possible damage from the existing distribution systems.
3.1.3. Load bearing capacity of the assembly site
- The selected assembly site must be suitable for the permanent load by the unit. In case of doubt, the
load capacity of the wall/walls must be verified by structural engineer or other responsible person.
3.1.4. Minimum assembly distances
- the minimum distance of the unit from the wall is 0.2 m. If this distance is not observed, the unit may not
work properly and the fan may be damaged or the unit’s noise may increase. The minimum height of
assembly of the unit from the floor is 2.5 m. Adjust the exhaust of the unit so that there is no draft in the
heated space. The air flow exiting the exhaust grid must not be directed directly to walls, beams, shelves,
machines, etc.

3.5. Water exchanger connection
3.5.1. Connection of the unit to the existing hot water distribution system
- Connect the unit to the heating system using a flexible connection (e.g. flexible hoses – with braided
armour). The heating system piping must not put any load on the exchanger throats.
3.5.2. Water exchanger connection
- Water supply and drainage necks are marked on the water exchanger collectors. To tighten the connected
piping to the unit, use the hexagonal profile on the water exchanger neck. This prevents the exchanger
outlet from being overturned, which may result in irreversible damage to the water exchanger.
- After connecting the water exchanger to the heating system, a pressure test of the unit connection is
recommended.
- The tests must be carried out by a person qualified in this field with knowledge of the applicable
regulations and standards of the country concerned.
- We recommend installing shut-off valves on the water exchanger inlet and outlet for the shut-off of the
heating medium, or to allow the unit dis-assembly without the need to drain water from the heating
system.
