REPOSITIONING OF INTERNAL COMPONENTS
COMMISSIONING
All TA units have been designed to facilitate the configuration and
customisation requested by the customer as much as possible.
In particular, it is possible to invert the position of the water coil
connections.
Water heating or cooling coil
If the water coil connections are not at the desired position, proceed
as follows:
• remove the upper panel and the air flow panel (coil side);
• re-mount the closing strap;
• pull the coil out;
• turn the coil 180°;
• put the coil back in and fasten it;
• re-mount the closing strap;
• put the panels back on;
As for the hydraulic connections, proceed as follows:
• connect the drain pipe to the threaded stub pipe of the tray and
plug the opposite unused stub pipe;
• cut the two plastic plugs;
• screw the threaded sleeves onto the coil collectors;
• tighten the air vent on the sleeve; this must be in the highest
position with respect to the other while the vent must be
positioned facing up.
Perform the connections on the system, isolate all the piping and
make sure that condensation drains correctly.
If water is used as the heat carrying fluid, the danger of freezing must
be absolutely avoid.
ATTENTION!
Make sure to have followed all instructions in this
manual before performing the first start-up checks.
Before starting the unit, check:
• that the voltage on the terminals is 230 V ± 5% controllable with a
tester: if the voltage is subject to frequent variations, contact the
Technical Dept. to select appropriate protections;
• that the unit is properly anchored;
• the unit connection to the building’s earthing;
• connection with the ducts;
• condensate draining connection with the siphon;
• insulation of coil supply pipes;
• absence of air inside the direct expansion and water coils;
• closure of panels that can be inspected;
• voltage available;
