Maintenance - Galletti FLAT Series Installation, Use And Maintenance Manual

FLAT
7 USE
To use the fan coil refer to the instructions on the control panel available as
accessory.
The air flow may be directed as desired using the upper FLAP (flow may be
directed upward or downward) as well as the second row of louvers (for
directing air flow either to the left or right). Figure 9
GB
The upper FLAP can also be used to start and stop the unit: when closed, it
corresponds to switching off the fan and the adjustment valve - if necessary
- (see wiring diagrams of the optional electric control panels). Figure 10
To prevent dust from getting inside the unit, always set the FLAP in the closed
position when the unit is not being used.
For safety reason, do not introduce your fingers or other pointed objects
in the air outlet grilles.

MAINTENANCE

For safety reasons, before carrying out any maintenance or cleaning jobs,
turn off the unit by moving the fan speed selector to "Off" and putting off
the main switch (0 position).
Due caution must be taken while carrying out maintenance: some metal
parts may cause injury: wear protective gloves.
FLAT type fan coils do not have particular maintenance requirements: it is
sufficient to periodically clean the air filter.
A running in period of 100 hours is necessary to eliminate all initial mechanical
friction of the motor.
Start-up should be carried out at the maximum operating speed.
To assure that the FLAT fan coil units perform efficiently, abide by the following
indications:
- keep the air filter clean;
- do not pour liquids inside the equipment;
- do not introduce metal parts through the air outlet grille;
- void obstructing the air outlet or intake.
Whenever starting up the unit after it has not been used for a long time, check
that there is no air in the heat exchanger.
Before the period of operation in the cooling mode, check that condensate is
properly drained and that the heat exchanger fins are not obstructed by
impurities.
Clean as necessary using compressed air or low pressure steam, taking care
not to damage the fins.
Adequate periodic maintenance will save both energy and money.

CLEANING THE AIR FILTER
Clean the air filter at least once a month and in any case at the start of the period
of use (before the heating and the air conditioning season).
To clean the air filter proceed as follows (FIGURE 11):
1. Remove the central screw securing the filter to the guide and free it from
its resting surface by tilting upward the part of the filter facing the wall the
unit is mounted on.
2. Take out the filter and clean it with warm water or, in the event of dry dust
build-up, using compressed air.
3. After allowing it to dry, fit the filter back in place, keeping the front part tilted
downward.
4. Once the filter is once more resting on the side panels of the base unit and
has been inserted into the front guide, replace the central screw to secure
it in place and prevent access to the fan.
WARNING: THE FILTER MUST ALWAYS BE SECURED IN PLACE WITH THE
SCREW PROVIDED TO PREVENT ACCIDENTAL CONTACT WITH THE FAN.
On models FLAT U the filter is slide fitted onto the air intake grilles. Take it out
as shown in figure 12.
It is recommended to replace the air filter once a year, using an original
replacement filter; the indoor unit model is specified on the identification plate
on the inside of the side panel.
CLEANING THE HEAT EXCHANGER
It is advisable to check the condition of the exchangers before the start of every
period of use and to make sure that the fins are not obstructed by dirt.
CLEANING THE CABINET
- Use a soft cloth.
- Never pour liquids onto the unit, as this could cause electrical discharges
and damage the internal components.
- Never use harsh chemical solvents; do not clean the air outlet flap with very
hot water.
