site. The
UA-UH 135-205 packaged
rooftop units are designed to provide a very high level of
safety and reliability making installation, start-up, operation
and maintenance easier and more secure. They will
provide safe and reliable service when operated within
their application range.
The procedures in this manual are arranged in the sequence
required for machine installation, start-up, operation and
maintenance.
Be sure you understand and follow the procedures and
safety precautions contained in the instructions supplied
with the machine, as well as those listed in this guide, such
as: protective clothing such as gloves, safety glasses, safety

The unit must be checked periodically during its whole
operating life for possible damage of the insulation (thermal,
acoustic) to ensure that no shocks (handling accessories,
tools, etc.) have damaged it. If necessary, the damaged
insulation parts must be repaired or replaced. See also
chapter “Maintenance”.

Moving and installation of the rooftop unit must always be in
accordance with the instructions below. If these instructions
are not observed, irreparable damage may occur to the unit,
and people in the immediate vicinity of the unit are also
endangered. Carrier does not accept any responsibility if
these instructions are not observed. Transport and lifting

After the unit has been received, and before it is started up,
it must be inspected for damage. Check that the refrigerant
circuits are intact, especially that no components or pipes
have shifted or been damaged (e.g. following a shock). If in
doubt, carry out a leak tightness check. If damage is detected

The unit must be installed in a place that is not accessible to
the public or protected against access by non-authorised
persons.
The unit should not be installed in an explosive atmosphere.

place and direction on the pallet of the unit.
The units can also be lifted with slings, using only the
designated lifting points marked on the unit (labels on
the chassis and a label with all unit handling instructions
are attached to the unit). Lifting under the cross beams is
prohibited. This applies to transport as well as storage.
Use slings with the correct capacity, and always follow
THELIFTINGINSTRUCTIONSONTHECERTIlEDDRAWINGSSUPPLIED
for the unit.
This unit is designed for ducted installation (indoor air
discharge). If ducts are not used the installer must place a
protection grille in the discharge.
Safety is only guaranteed, if these instructions are carefully
followed. If this is not the case, there is a risk of material
deterioration and injuries to personnel.
These units are not designed to be lifted from above.
All precautions concerning handling of refrigerant must
be observed in accordance with local regulations.
Accumulation of refrigerant in an enclosed space can
displace oxygen and cause asphyxiation or explosions.
Inhalation of high concentrations of vapour is harmful
and may cause heart irregularities, unconsciousness, or
death. Vapour is heavier than air and reduces the amount
of oxygen available for breathing. These products cause
eye and skin irritation. Decomposition products can be
hazardous.
