Preparation
5.1
Overview: Preparation
This chapter describes what you have to do and know before going
on-site.
It contains information about:
▪ Preparing the installation site
▪ Preparing the unit
▪ Preparing the electrical wiring
▪ Preparing the installation of the ducts
5.2
Preparing the installation site
Do NOT install the unit in places often used as work place. In case
of construction works (e.g. grinding works) where a lot of dust is
created, the unit MUST be covered.
Choose an installation location with sufficient space for carrying the
unit in and out of the site.
Do NOT install a heat reclaim ventilation unit or air suction/discharge
grille in the following places:
▪ Places, such as machinery plants and chemical plants, where
noxious gases or corrosive components of materials such as acid,
alkali, organic solvent and paint are present.
▪ Places, such as bathrooms, subject to moisture. Moisture can
cause electric shock, electric leakage and other failures.
▪ Places subject to high temperature or direct flames.
▪ Places subject to much carbon black. Carbon black attaches to air
filter and heat exchange elements, disabling them.
5.2.1
Installation site requirements for the heat
reclaim ventilation unit
INFORMATION
Also read the general installation site requirements. See
the "General safety precautions" chapter.
CAUTION
▪ The appliance is designed to be a built-in appliance. It
must NOT be accessible to the general public.
Adequate measures have to be taken to prevent
access by other than qualified persons.
▪ Check if the installation location can support the unit's
weight. Poor installation is hazardous. It can also cause
vibrations or unusual operating noise.
▪ Provide sufficient service space and inspection holes.
Inspection holes are needed for the air filters, the heat
exchange elements and the fans.
▪ Do NOT install the unit so that it is in contact with a
ceiling or wall, this may cause vibration.
CAUTION
Appliance NOT accessible to the general public, install it in
a secured area, protected from easy access.
