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 curved doorways. 

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 are available. See wiring diagram (p. 6). 

Water coil connection

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.

The water pipes are connected to the 

terminals with DN25 (1"), internal thread on 
the inside of the unit. Use a wrench or similar 
to hold the air curtain connections to prevent 
straining the pipes and subsequent water 
leakage during connection to water supply 
pipe-work.

The connections to the heating coil must be 

equipped with shut off valves 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 installation must 
be carried out by an authorised installer.

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.
