AC Corinte
wiring diagram on page 5-10.
The front panel/service hatch does not need
to be opened for electrical installation.
Starting-up
Note! When using for the first time or when
starting up after a long period of disuse, a
small amount of smoke and a slight odour
may occur temporarily, which is completely
normal.
Water coil connection
The installation must be carried out by
an authorised installer. The water coil has
copper tubes with aluminium fins and is
suitable for connection to a closed water
heating system. The heating coil must not be
connected to a mains pressure water system
or an open water system.
Use a wrench or similar to hold the
connections on the air curtain side to prevent
straining the pipes and subsequent water
leakage during connection to water supply
pipe-work.
The connections to the coil must be
equipped with shut off valves and drain valve
to allow problem free removal.
The highest point of the pipes supplying
the unit with water must also be fitted with a
bleed valve.
The front panel/service hatch is opened by
slackening off the screws on the exhaust side.
See page 4.
Horizontal unit
Connections with internal threads are on the
upper side of the unit. See dimensions table
on page 2.
Vertical unit
Connection can be carried out through the
opening if the intake grille is removed, see
page 4, front panel/service hatch does not
need to be opened.
Connections with internal threads, union
connection, are on the inside of the unit. See
dimensions table on page 2.
Adjustment of the air curtain and air flow
The direction and speed of the air flow should
be adjusted considering the wind/draught
load on the opening. Pressure forces affect
the air stream and make it bend inwards into
the premises (when the premises are heated
and the outdoor air is cold).
The air stream should therefore be directed
outwards to withstand the load. Generally
speaking, the higher the load, the greater the
angle that is needed.
Basic setting of fan speed
The fan speed when the door is open is set
using the speed control. Note that the air
flow direction and speed may need fine
adjustment depending on the loading of the
door.
Service, repairs and maintenance
For all service, repair and maintenance first
carry out the following:
1. Disconnect the power supply. Note! Units
with electrical heaters can be supplied
from more than one connection.
2. The front panel/service hatch is opened by
slackening off the screws on the exhaust
side. See fig. 4.
Maintenance
Since fan motors and other components are
maintenance free, no maintenance other
than regular cleaning is necessary. The
frequency of cleaning can vary depending
on local conditions, but undertake cleaning
at least twice a year. Inlet and exhaust
grilles, impeller and elements can be vacuum
cleaned or wiped using a dry cloth. Use a
brush when vacuuming to prevent damaging
sensitive parts. Avoid the use of strong
alkaline or acidic cleaning agents.
Overheating
The average temperature of the outlet air is
restricted to +40 °C on the electrical unit.
The air curtain unit with electric heater is
equipped with an overheat protector. If this is
deployed due to overheating, reset as follows:
1. Disconnect the electricity using the
omnipolar switch.
2. Allow the electrical coil to cool.
