AC Corinte
Assembly and operating instructions
General Instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The guarantee is only valid if the units
are used in the manner intended by the
manufacturer and in accordance with the
Frico mounting and operating instructions.
Application area
The Thermozone AC Corinte air curtain is
supplied with electrical heating or water coil
and is intended for permanent installation
above or beside entrance doors and other
openings up to 3 metres in height.
Protection class: IP20
Operation
Air is drawn in at the top/rear of the unit and
blown out downwards/outwards so that it
shields the door opening and minimizes heat
loss. To achieve the optimum curtain effect
the unit must extend the full height/width of
the door opening.
The grille for directing exhaust air is
adjustable and is normally angled outwards to
achieve the best protection against incoming
cold air.
The efficiency of the air curtain depends
on the air temperature, pressure differences
across the doorway and any wind pressure.
NOTE! Negative pressure in the building
considerably reduces the efficiency of the air
curtain. The ventilation should therefore be
balanced.
Installation
Leave the protective plastic in place when
installing the stainless steel version of
AC Corinte. Take care not to damage the
surfaces.
Vertical mounting
Before installation, decide whether any
electrical connections or water connections
are to be made from below.
For vertical installation of AC Corinte,
install standing on the floor on adjustable feet
to compensate for any surface undulations.
The feet are secured to the floor and covered
by a cover frame.
The unit is installed as close to the door
as possible, preferably against the wall or
immediately beside the doorway.
The unit must be secured at the top with
an angle bracket or similar to prevent it from
toppling over. There is a hole at the top of
the air curtain with an internal M6 thread for
securing the bracket.
Ensure that the front panel/service hatch is
accessible and can be fully opened.
See details on page 2-4.
Horizontal mounting
For horizontal installation of AC Corinte,
install with the supply air grille downwards
as close to the door as possible, preferably
against the wall and immediately above
the doorway. For the protection of wider
doorways, several units can be mounted next
to each other.
For wall mounting, use two or three
brackets (accessories).
Alternatively the unit can be suspended
from the ceiling. For mounting there are M8
internal threads (ACC1000 and ACC1500
have four and ACC2000, ACC2500 and
ACC3000 have six).
Ensure that the front panel/service hatch is
accessible and can be fully opened.
See details on page 2-4.
Electrical installation
The installation, which should be preceded
by an omnipolar switch with a contact
separation of at least 3 mm, should only
be wired by a competent electrician and in
accordance with the latest edition of IEE
wiring regulations.
The unit has pre-connected supply and
control wiring (1.5 metres).
Different combinations for controlling fan
speed and heat output are available. See
wiring diagram on page 5-10.
The front panel/service hatch does not need
to be opened for control options 1 and 2. For
