Swegon TCLF Installation Instructions

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
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.

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.
