5. SELECTING INSTALLATION SITE
5.1. General
■ The equipment is not intended for use in a potentially explosive
atmosphere.
■ Choose a place solid enough to bear the weight and vibration of
the unit, where the operation noise will not be amplified.
■ Choose a location where the hot air discharged from the unit or
the operation noise will not cause a nuisance to the neighbours
of the user.
■ Avoid places near a bedroom and the like, so that the operation
noise will cause no trouble.
■ There must be sufficient space for carrying the unit into and out
of the site.
■ There must be sufficient space for air passage and no
obstructions around the air inlet and the air outlet.
■ The site must be free from the possibility of flammable gas
leakage in a nearby place.
■ Locate the unit so that the noise and the discharged hot air will
not annoy the neighbours.
■ Install units, power cords and inter-unit cables at least 3 m away
from television and radio sets. This is to prevent interference to
images and sounds.
