The choice and sizing of the water lines is the responsibility
of the designer, who must apply best working practice and
comply with the legislation in force, also considering that
undersized lines will lead to poor performance.
The water lines and the joints must be thermally insulated.
Make sure the pipes are completely insulated.
Avoid over-tightening so as to not damage the insulation.
To make the connections:
- position the water lines
- tighten the connections using two spanners in opposite
directions
- check for any leaks
- cover the connections with insulating material
To ensure water tightness of threaded connections, use
plumber’s hemp and green paste; Teflon tape is recommended when antifreeze is added to the water circuit.
I A
CONDENSATE DRAIN
The condensate drain line must be suitably sized (pipe with
a minimum inside diameter of 16 mm) and the pipe laid out
as to ensure a minimum slope of 1% along the entire line.
For vertical installation, the drain line is connected directly to
the drain pan, located at the bottom of the side frame,
underneath the water connections.
For horizontal installation, the drain line is connected to the
drain pipe already fitted on the unit.
For horizontal installation of DLMO versions, the horizontal
condensate collection pan kits are available as accessories.
- If possible, discharge the condensate directly into a gutter
or a storm water drain.
- If draining into the sewers, a drain trap should be fitted to
prevent bad odours from drifting back into the rooms.
The bend in the drain trap must be lower than the condensate collection pan.
- If discharging the condensate into a container, this must
be open and the drain pipe must not be immersed in the

water, so as to avoid surface tension and backpressure
that would prevent correct drainage.
- If needing to overcome a raised section that wold prevent
condensate drainage, a pump must be installed:
- for vertical installation, fit the pump underneath the side
drain pan;
- for horizontal installation, the position of the pump should
be determined according to specific needs.
These pumps are widely available on the market.
In any case, following installation check correct condensate
drainage by pouring very slowly (around 1/2 l of water in
around 5-10 minutes) into the collection pan.
Make sure that the drip guard is installed correctly.
