1 – Introduction
These instructions pertain to Optyma G&D
HBP DSH105 condensing units (R410A)
used for refrigeration systems. They provide
necessary information regarding safety and
proper usage of this product.
The condensing unit includes following:
• Scroll compressor
• Microchannel heat exchanger
• Fix low Pressure cartridge
• Fix high pressures cartridge
• Fix Fan control pressures cartridge
• Service valves Suction/ liquid
• Crankcase heater for compressor
• Receiver with stop valve
2 – Handling and storage
• It is recommended not to open the
packaging before the unit is at the final
place for installation.
• Handle the unit with care. The packaging
allows for the use of a forklift or pallet jack.
Use appropriate and safe lifting equipment.
• Store and transport the unit in an upright
position.
• Don't expose the packaging to rain or
corrosive atmosphere.
• Store the unit between -35°C and 50°C.
• After unpacking, check that the unit is
complete and undamaged.
3 – Installation precautions
Do not braze as long the condensing unit
is under pressure.

Never place the unit in a flammable
atmosphere.
IPlace 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
picture1 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
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 50°C during off cycle.
• Ensure that the power supply corresponds
to the unit characteristics (see nameplate).
• When installing units for HFC refrigerants,
use equipment specifically reserved for
HFC refrigerants which was never used for
CFC or HCFC refrigerants.
• Use clean and dehydrated refrigeration-
grade copper tubes and silver alloy brazing
material.
• Use
clean
and
components.
• The
suction
piping
the compressor must be flexible in
3 dimensions to dampen vibrations.
Warnings
The condensing unit must only be used for its designed purpose(s) and
within its scope of application.
Under all circumstances, the EN378 (or other applicable local safety
regulation) requirements must be fulfilled.
The condensing unit is delivered under nitro- gen gas pressure (1 bar)
and hence it cannot be connected as it is; refer to the «installation» section
for further details.
The condensing unit must be handled with cau- tion in the vertical
position (maximum offset from the vertical: 15°)
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.
4 – Installation
• The unit must be securely installed on a
stable and rigid support and fixed 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 schrader 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
technique and vent piping with nitrogen
gas flow.
• Connect the required safety and control
devices. When the schrader port is used for
this, remove the internal valve.
• It is recommended to insulate the suction
pipe up to the compressor inlet with 19mm
thick insulation.

5 – Leak detection
Never pressurize the circuit with oxygen
connected
to
or dry air. This could cause fire or explosion.
• Do not use dye for leak detection.
