1.2.1
General
If you are not sure how to install or operate the unit, contact your
dealer.
NOTICE
Improper installation or attachment of equipment or
accessories could result in electric shock, short-circuit,
leaks, fire or other damage to the equipment. Only use
accessories, optional equipment and spare parts made or
approved by ROTEX.
WARNING
Make sure installation, testing and applied materials
comply with applicable legislation (on top of the
instructions described in the ROTEX documentation).
CAUTION
Wear adequate personal protective equipment (protective
gloves, safety glasses,…) when installing, maintaining or
servicing the system.
WARNING
Tear apart and throw away plastic packaging bags so that
nobody, especially children, can play with them. Possible
risk: suffocation.
DANGER: RISK OF BURNING
▪ Do NOT touch the refrigerant piping, water piping or
internal parts during and immediately after operation. It
could be too hot or too cold. Give it time to return to
normal temperature. If you must touch it, wear
protective gloves.
▪ Do NOT touch any accidental leaking refrigerant.
WARNING
Provide adequate measures to prevent that the unit can be
used as a shelter by small animals. Small animals that
make contact with electrical parts can cause malfunctions,
smoke or fire.

accessible place at the product:
▪ Instructions for shutting down the system in case of an emergency
