| Instructions on the protective measures during repair and maintenance
Claim for reduction of danger:
• Installer and user must be aware of the fact that lightning makes a risk that requires installation of overvoltage pro-
tection devices to lead the lightning overvoltage to an earth lead on a safe way. The need for overvoltage protection
devices depend on where the unit is placed in and on the building.
• Installer and user must take care of this according to local statutory requirements. Overvoltage protection devices
are also described in chapter I.3.3.2 of this manual

Instructions on the protective measures during repair and maintenance
Use the below-mentioned personal protective equipment for maintenance:
• Cut-resistant gloves for protection against injury from sharp metal plate edges. Use CE-marked gloves for this
purpose.
• Helmet
• Particulate respirator – maintenance free including foam face-seal and adjustable pre-threaded headbands – for re-
placing filters.
• Padlock for locking the automatic circuit breakers in off position
• Permanent magnet motor. The shaft must be blocked during repairs and maintenance of the electric system (the
motor generates electricity by rotation – for example that the wind and thermic drives the fan/motor).
• Lighting inside the units. According to the latest interpretations of the Machinery Directive by the authorities suffi-
cient lighting inside the units is mandatory.
• Tools to block the impeller during repairs and maintenance if stack effect – also called chimney effect – in the ducts
create airflows that drives the impellers by turned off motors
N
The essential characteristics of tools which may be fitted to the machinery
The subject in the Machinery Directive about tools on the machine does not exist for the Geniox air handling units, be-
cause those tools does not exist.
O
The conditions of stability during use, transportation, assembly, dismantling
when out of service
The unit must always be handled in an upright position. Never tilt any section more than 15 degrees. If sections must
be tilted more than 15 degrees, sections with fans or rotating exchangers that can be drawn out for service must be se-
cured carefully.
During transportation, installation, dismantling or other handling, it must be secured that all components in the unit are
properly fastened and with additional attention to the control of anti-vibration mounts under the fans that they are un-
damaged. The mounting and smooth running of the fans must be controlled and handled with great care.
O.1
Installed reliable to avoid units to be tilted or moved by storm
Units installed on roofs and other places with the risk of heavy winds must be installed reliable to avoid that they can
be tilted or moved by the any storm. The base frame is provided with holes that are intended for fastening by sufficient
bolts and fittings supplied by the installer.
O.2
Transport of section with heat pump unit
Warning
During transportation, the unit section – Geniox Core — HP
must
always be in the upright position or tilted
less than 30˚. If it is necessary to tilt the unit more than 30˚, the suction pipe of the compressor must point
upwards to prevent the escape of oil from the compressor sump.
O.3
Disposal of the heat pump system - type Geniox Core - HP
Prior to the disposal of the Geniox Core — HP unit section, the refrigerant in the heat pump system must be drained off
by a skilled technician from a certified company. After correct evacuation of the refrigerant, the disposal of the Geniox
— HP unit section is similar to the disposal of the rest of the air handling unit.
