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 RD air curtain unit is intended for 
installation in revolving doors. 

RD is installed concealed on top or inside 

the revolving door.

Operation

Air is drawn in at the upper side of the 
unit and blown out downwards towards the 
entrance so that it shields the door opening 
and minimizes heat loss. To get the best 
curtain effect the unit must extend the full 
width of the door opening. 

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 eficiency of the air 
curtain. The ventilation should therefore be 
balanced!

Installation 

RD is installed concealed on top or inside the 
revolving door.

Ensure that the service hatch is accessible 

and can be fully opened.

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 upper or lower side of 
the unit.

2. The unit is connected via one of the cable 

glands on the right side of the unit (seen 
from inside) 

  
Different combinations for controlling fan 
speed are available. See wiring diagram 
(p.5). 

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 right side 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 speed may need fine adjustment 
depending on the loading of the door.

Filter

The heat coil plate distance makes a separate 
filter unnecessary.
