Maintenance of the units
To assure proper operation of the units
with minimum electric consumption and a
long operating life, a regular maintenance
schedule should be established.
The following table recommends the fre-
quency of the usual maintenance opera-
tions, although it may be necessary to vary
these, depending upon the operating and
ambient conditions of each unit.
Qualified technical personnel only should
carry out maintenance operations, updating
the log of all maintenance.
Attention: Prior to accessing the interior of
the units disconnect all power supplies.
- Outdoor and indoor fan belts: Check
belt conditions and tension. If replaced
with new belts, these should be of the
same type and gauge as the originals, and
tension should be checked within the next
24 hours of operation.
- Air filters: Slide them out of the units on
their guide rails and wash.
- Indoor coil: A visual inspection is recom-
mended when servicing the filters. The
entire surface of the fins must be kept free
of dirt. If it requires cleaning, use a soft

brush or a vacuum cleaner, making sure
not to damage the fins.
Never use water hoses in the interior of
the compartment.
- Condensed water tray and siphon:
Eliminate all dirt and residues. Make sure
the water drain and the siphon are not
obstructed. Make sure the water is evacu-
ated correctly. Prime the siphon (fill with
water) if necessary.
- Outdoor coils: Eliminate all dirt and resi-
dues found on the surface of both sides of
the coils. Clean the surface of the fins with
a soft brush or a vacuum cleaner, making
sure not to damage them. Since the units
are exposed to the outdoor environment,
it may be necessary to use water and an
detergent for cleaning. In this case, always
apply from inside to the exterior, and up
and down.
- Outdoor air intake: If the unit includes
any of the accessories, such as an econo-
mizer or a return fan, the dampers should
be serviced by checking correct operation
of their components (shafts, fins, motor).

ments, temperature variations, and carry
out any other checks needed.
- Mechanical and electrical operation:
Also at the beginning of each season,
check the amperage of all motors, the
conditions of electrical connections and
the operation of the safety controls. The
bearings of both the indoor as well as the
outdoor fan motors are of the permanent
lubrication type and require no mainte-
nance.
- Integrity of the structure and compo-
nents of the unit: Check the conditions
of the outdoor structure and components
of the unit, the non-existence of impacts or
dents and correct fastening of the bolts.
Check correct closing of the access doors,
including the conditions of the sealing
gaskets and the locks.
- Hot water coil: If the equipment is
equipped with this accessory: At the
beginning of the heating season, check
the operation of the control elements, the
water in the system and the purging of air
in the coil. Depending upon the area and
installation, and if necessary, make sure
the proportion of antifreeze is correct.
