Installation Instructions for the 
TBLF/TCLF Air Heater, for water
GOLD

1. General

The TBLF/TCLF air heater uses hot water as the heating 
medium for preheating the supply air. Install the TBLF in 
the outdoor air duct.

Finned-tube heat exchanger fabricated of copper tubes 
and profi led aluminium fi ns. Fin pitch: 5.5 mm. The head-
ers and the pipework to the water connections are made 
of copper. The male threaded pipe connections are made 
of brass.

The control functions for preheat are integrated into the 
control equipment of the air handling unit. Temperature 
sensor for duct and IQlogic

+

 with a 0.25 metre long cable, 

frost guard sensor (insertion type), and T-piece (for air 
heaters without outlet for an insertion sensor) are included 
in the air heater supply.

Extra accessories 

Circulation pump used for ensuring the frost guard func-
tion for the air heater. Supplied with T coupling, non-
return valve and commissioning valve. The automatic 
pump control system is integrated into the control equip-
ment of the air handling unit. See the individual instruc-
tions for the TBPA accessory. 

The TBVL valve set with 2(3)-way valve, actuator, con-
nection cable with quick-fi t connector, frost guard sensor 
(insertion type), and T-piece (for air heaters without outlet 
for an insertion sensor). See the individual instructions for 
the TBVL. If the air heater is to be installed outdoors or in 
a cold space, take into consideration the enclosure class of 
the actuator and the permissible ambient temperature.  If 
necessary, see to it that required protection is arranged. 

If you use a valve of your own, you have the option of 
instead selecting a set of electrical connection compo-
nents. This set contains a connection cable with quick-fi t 
connector, resistor and insertion or strap-on sensor.

2. Maintenance

Check at least twice a year whether cleaning is necessary.

Cleaning shall only be done by blowing with compressed 
air against the ordinary direction of airfl ow, vacuum clean-
ing with a soft nozzle or wet cleaning with water and/
or solvent. Before you begin wet cleaning, you should 
cover adjacent functional sections to protect them. After 
wet cleaning, you should blow the surfaces dry with com-
pressed air to remove every trace of cleaning solvent.

TCLF

If cleaning solvent is used, this solvent must not contain 
ingredients that will corrode aluminium or copper. Swe-
gon’s cleaning agent is recommended. This cleaning agent 
is sold by Swegon or Swegon Service.

While cleaning, check whether the liquid circuit needs to 
be vented.
