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.
