Swegon TBLA Installation Instructions

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.
Swegon reserves the right to alter specifications.
