FIGURE 1 - HANDLING OF US A UNITS.
3. SAFETY INSTRUCTIONS
The new indoor units US A were projected to offer
you a safe and reliable service when operated within the
specifications foreseen in project.
However, due to this same conception, aspects
regarding installation, start up and maintenance should be
strictly observed.
WARNING
* Verify the weights and dimensions of the units (see
item 13) to guarantee an appropriate and safe handling.
* Learn how to handle the oxyacetylene equipment
safely. Leave the equipment in the vertical position
inside the vehicle and also in the working place.
* Use dry nitrogen to pressurize and to check the system
for leaks. Use a good regulator. Be careful not to
exceed 200 psig of test pressure in the rotary
compressors.
* Before working in any one of the units always turn off
the power supply unplugging the indoor unit from the
wall outlet.
* Never introduce the hands or any other object inside
the units while the fan is working.
4. RECEPTION AND INSPECTION
OF THE UNITS
* To avoid damages during handling or transport, don’t
remove the unit’s packing until arrive to the defined
place of installation.
* Prevent strings, chains or other devices from touching
the units.
Never lift or carry the evaporator unit by the
plastic side parts. Hold it on the metal parts, as
shown on figure 1.
WARNING
* Observe the limit of suitable piling up indicated in the
units’packing.
* Don’tshake the outdoorunit during transportationnor
incline more than 15oin the vertical.
* Avoid exposing the machine labor accidents, seeing
to it that it is immediately carried to the installation
site or a safe place.
* When removing the units from the package and
removingthe expanded polystyreneprotectionsdon’t
discardthem immediately because theymaybeuseful
eventuallyas protection against dust,orother noxious
agentsuntil the building and/orinstallationis comple-
te and system ready to operate.
5. INSTALLATION
5.1 GENERAL RECOMMENDATIONS
First, consult the norms or codes applicable to the
installationof the equipmentinthe selected place,to make
sure the system is in accordance to them.
Make also a careful planning of the unit location to
avoid interference with any type of existing (or planned)
facilities,suchaselectricalinstallation,waterpiping,sewer,
etc.
Install the units so that they are free from any type of
obstruction from the taking of return air or airflow.
Choose places with enough clearance for repairs or
services of any kind and also to make the piping
easier(copper tubes that interconnect the units, electrical
wiring and drain).
Remember that the units should be leveled after their
installation.
Verify if the external place is free of dust or other
particles that might obstruct the condenser coil.
* Always maintain the fire extinguisher close to the
working place. Check the extinguisher periodically
to certify it is completely loaded and working
perfectly.
* When working in the equipment always observe the
safety warnings in the labels attached to the units.
* Always follow all the applicable norms of safety
and use clothes and equipment of personal
protection. Wear gloves and protection glasses
when handling the units or the system refrigerant.

It is indispensable that the indoor unit possesses
hydrauliclinefor drainage of the condenser.Thishydraulic
line should not have a diameter less then 1/2" and should
have, right after the exit, a siphon to guarantee a perfect
fall and isolation of air. At the start up, this siphon should
befilled in with watertoavoid taking air fromthedrainage
line.The drainage intheoutdoor unit is indispensableonly
when installed in the high and causing leak risk.
