General instructions
Read these instructions carefully before
installation and use. Keep this manual for
future reference.
The guarantee is only valid if the
Thermozone units are used in the manner
intended by the manufacturer and in
accordance with the Frico installation and
maintenance instructions.
Application area
The SF air curtain unit is intended for
installation in revolving doors.
SF is installed to the side of the entrance.
Operation
Air is drawn in at the side of the unit and
blown out towards the entrance so that it
shields the door opening and minimizes heat
loss. To achieve the optimum curtain effect
the unit must extend the full height of the
door opening.
The grille for directing exhaust air is
adjustable and is normally angled towards the
curved doorway to achieve the best protection
against incoming cold air.
The airflow can be adjusted by use of the fan
speed selector.
The efficiency of the air curtain(s) 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
The unit is installed as floor standing on
adjustable feet that make it possible to
compensate for possible irregularities in the
floor. The feet are bolted to the floor and
covered by a covering edge. SF is mounted
to the left of the door seen from inside the
building and should also be secured to the
door. SF has a curved design that integrates
neatly with the door. Extension is possible up
to 3900 mm (extension without fans).
Ensure that the service hatch is accessible
and can be fully opened.
See sketches p.2-3.
Electrical installation
Electrical connection may only be carried
out by an authorized electrician, and in
accordance with these instructions and the
applicable regulations.
1. The service hatch is opened by slackening
off the screws in the side of the unit.
2. The unit is connected via one of the cable
glands in the upper or lower side of the
unit.
Different combinations for controlling fan
speed and heat output are available. See
wiring diagram (p.5). Connections are made
using EKK, EKLK or corresponding type
cables. The cable glands used must meet the
protection class requirements. For units with
electrical heating, the power and control
voltage can be supplied separately. It must be
indicated in the distribution board that ”The
air curtains are supplied from more than one
connection”.

Basic setting fan speed
The fan speed 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.
2. The service hatch is opened by slackening
off the screws in the side of the unit.
