Do not braze if the condensing unit is under
pressure.
Never place the unit in a flammable
atmosphere.
Place the unit in such a way that it is not
blocking or hindering walking areas, doors,
windows or similar.
• Ensure adequate space around the unit for air
circulation and to open doors. Refer to picture 1
for minimal values of distance to walls.
• Avoid installing the unit in locations which are
daily exposed to direct sunshine for longer
periods.
• Avoid installing the unit in aggressive and/or
dusty environments.
• Ensure a foundation with horizontal surface (less
than 3° slope), strong and stable enough to carry
the entire unit weight and to eliminate vibrations
and interference.
• The unit ambient temperature may not exceed
120 °F during off-cycle.
• Ensure that the power supply corresponds to
the unit characteristics (see nameplate).
• Use clean and dehydrated refrigeration-grade
copper tubes and silver alloy brazing material.
• Use clean and dehydrated system components.
• The suction piping connected to the compressor
must be flexible in 3 dimensions to dampen
vibrations. Furthermore piping has to be done
in such a way that oil return for the compressor
is ensured and the risk of liquid slug over in
compressor is eliminated.
• The unit must be securely installed on a stable
and rigid support, and fix from the beginning.
• It is recommended to install the unit on rubber
grommets or vibration dampers (not supplied).
• Slowly release the nitrogen holding charge
through the Schraeder port.
• Connect the unit to the system as soon as
possible to avoid oil contamination from
ambient moisture.
• Avoid material entering into the system while
cutting tubes. Never drill holes where burrs
cannot be removed.
• Braze with great care using state-of-the-art
techniques and vent piping with nitrogen gas
flow.
• Connect the required safety and control devices.
Remove the internal valve when using the
Schraeder port for this.
• It is recommended to insulate the suction pipe
up to the compressor inlet with 3/4" mm thick
insulation.
