Unit Installation - Carrier AQUASMART 42WHC Installation Manual

42 WHC/AQUASMART

Unit installation

At this point the unit can be installed by completing the water and
electrical connections.
Hook the unit onto the hanging plate, using the lower hooks
chain .
Finish making the water connections
If the installation is made using the panel with valves, connect the
flexible pipes to the coil pipes following the "inlet/outlet"
indications on the plate (IN/OUT plate on the pipes).
To ensure correct installation, it is important to make certain that
the 90° coupling on the flexible pipe is perpendicular to the unit
back when tightening this to the unit pipes.
If the installation is made using the panel without valves,
connect the system pipes to the coil pipes following the water
"inlet/outlet" indications (IN/OUT plate on the pipes).
Note:
Do not bend or crush the unit pipes.
Avoid tight bends with a radius of less than 100 mm.
Do not bend the pipe more than three times in the same place.
Do not excessively compress the insulation on the connection pipes
with clamps and tape.
Condensate drain pipe and other piping
and
Position the condensate drain pipe towards its hole in the panel
and ensure that this slopes towards the outside.
Connect this pipe to a suitable drain using PVC pipe.
The horizontal lengths between the indoor unit and the drain must
have a minimum slope of 2%.
Completing the electrical connections
Complete the electrical connections by connecting the unit wiring
connectors to the printed circuit (see the Electrical Connections
paragraph).
Check
Check that the system is filled with water and check the tightness of
all connections/fittings.
Tube
Tube insulation
Fastening tape
Finally wrap connections with anti-condensate insulation and
tighten with tape, without exerting great pressure on the insulation.
Repair and cover any possible cracks in the insulation.
Connection pipes and electric cables must be fixed to the wall
using appropriate conduits.
Carefully insulate the pipes close to the valve couplings to prevent
condensate from forming on them and possible dripping.
