Installation Instructions for the TBLA Air Heater with
Thermo Guard frost damage protection, GOLD/SILVER C
1. General
The TBLA air heater uses hot water as the heating medium
for post-heating the supply air.
Finned-tube heat exchanger fabricated of copper tubes
and profiled aluminium fins. The headers and the pipe-
work to the water connections are made of copper. The
male threaded pipe connections are made of brass.
Extra accessories
GOLD:
The TBVL valve set with 2(3)-way valve, actuator, con-
nection cable with quick-fit 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 valve set.
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-fit
connector, resistor and insertion or strap-on sensor.
SILVER C:
The TBVA Valve set consisting of a 2(3)-way valve includ-
ing actuator can be ordered. See the instructions for
TBVA accessories. If the air heater/cooler is to be installed
outdoors or in a cold space, take into consideration the
enclosure class of the actuator and the permissible ambi-
ent temperature. If necessary, ensure that the required
protection is arranged.
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 airflow, 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.
