CONDENSATE DRAIN

I A

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.

C drip guard

Assembling the condensate drain pipe on vertical ver­sions

Connect a drain pipe to the condensate collection pan drain
fitting and secure it in place.

Make sure that the drip guard is installed correctly.

WATER CONNECTIONS

I A

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.

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

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 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.

Assembling the condensate drain pipe on horizontal
versions

To assemble the horizontal drain pan on DLMO versions,
see the instructions supplied with the horizontal pan kit.

- make sure that the “L” pipe and the rubber hose are cor­rectly connected to the pan.

- insert the side of the unit, keeping the pipe held against
the front grill.

- close the side, making sure the pipe remains secured in
the groove provided on the side.

- If necessary, cut the plastic tube C for the condensate
drain and fix the painted pipe to the plastic tube with the
supplied clamp so that the knot of the clamp is facing
away from the cabinet to keep the pipe to the right slope

for the correct condensate drain. (see fig. 1)

N.B. warnings for horizontal installation:

- make sure that the unit is perfectly level, or with a slight
slope towards the condensate drain;

- carefully insulate the outlet and return pipes all the way to
the unit, so as to prevent condensate from dripping out­side of the collection pan;

- insulate the entire condensate pan drain pipe.

cold water in the circuit.

- Water leaks from the appliance in heating mode.

- Water leaks from the appliance in cooling mode only.

- The appliance is very noisy.

- Dew forms on the front panel.

TROUBLESHOOTING TABLE

U A

The following operations must be performed by a qualified installer or a specialist service centre.

TIPS ON SAVING ENERGY

I A

- Keep the filters clean at all times;

- where possible, keep the doors and windows in the air­conditioned room closed;

- where possible, in cooling operation limit exposure of the
air-conditioned room to direct sunlight (use curtains, shut­ters, etc.).

Fault Possible cause Solution

The fan starts after a delay from changing the
temperature settings or function.

The circuit valve takes some time to open and
let hot or cold water circulate in the appliance.

Wait 2 or 3 minutes for the circuit valve to
open.

The fan does not start. No hot or cold water in the system.

Make sure that the boiler or water chiller are
operating.

The fan does not start active even when there
is hot or cold water in the circuit.

The water valve remains closed

Remove the valve body and check if water
starts circulating.

Check valve operation by powering it sepa­rately at 230 V.
If the valve is activated, the problem may lie in
the electronic controller.

The fan motor is blocked or burnt out.

Check the motor windings and make sure the

fan can spin freely.
The microswitch that stops the fan when
opening the filter grill does not close correctly.

Make sure that when closing the grill, the

microswitch contact is activated.
Incorrect electrical connections. Check the electrical connections.

Water leaks from the appliance in heating
mode.

Leaks from the system water connections.

Check the leaks and fully tighten the connec-

tions.
Leaks from the valves. Check the gaskets.

Dew forms on the front panel. Heat insulation detached.

Make sure that the heat insulation/sound-

proofing is positioned correctly, especially at

the front above the finned coil.

There are droplets of water on the air outlet
louvers.

When relative humidity inside the room is
quite high (>60%), condensate may form,
especially at low fan speed.

When the relative humidity falls, the phenom-

enon will disappear.

In any case, the formation of some droplets of

water inside the appliance does not indicate a

malfunction.

Water leaks from the appliance in cooling
mode only.

The condensate pan is blocked.

Slowly pour a bottle of water into the bottom

of the coil to check drainage; if necessary,

clean the pan and/or increase the slope of the

drain pipe.

The condensate drain is not sloped down­wards enough for correct draining.

The connection pipes and valves are not
properly insulated.

Check the insulation on the pipes.

The appliance is very noisy.

The fan is touching the structure. Check the filters and clean them if necessary.

The fan is unbalanced.

An unbalanced fan will cause excessive vibra-

tions on the unit: replace the fan.

Check the filters and clean them if necessary Clean the filters

The louvers stay open.

Possible obstruction blocking rotation.

Remove the obstruction, power off the appli-

ance, wait 2 minutes and power the appliance

on again. The louvers close correctly.

Power failure or disconnection during move­ment of the louvers.

Restore power to the appliance.
