Danfoss Optyma Plus OP-MPS Serie Manual De Instrucciones página 2

Instructions (English)
Optyma™ Plus
OP-MPS, OP-MPT, OP-LPV, OP-LPK and OP-MPI
Optyma™ Plus electrical box ingress protection level is IP54 to avoid quick A2L refrigerant migration. Sealing needs to be maintained and any damage on
sealing needs to be repaired appropriately. (See section 8 - Safety)
E-Box door must always be closed during operation and after service/periodic maintenance.
Installation and servicing of the condensing units by qualified personnel only. Follow these instructions and sound refrigeration engineering practice relating to instal-
lation, commissioning, maintenance and service.
The condensing unit must only be used for its designed purpose(s) and within its scope of application and according to instruction. Refrigerant to be used as per
specification with respect to model.
Under all circumstances, the EN378 and other applicable local safety regulation requirements must be fulfilled.
The condensing unit is delivered under nitrogen gas pressure (2 bar(gauge)) and hence it cannot be connected as it is; refer to the «installation» section for
further details.
The condensing unit must be handled with caution in the vertical position (maximum offset from the vertical : 15°)
Condensing units can be used with A2L refrigerants, necessary care to be taken during installation and servicing.
In case of A2L refrigerants, all components on the refrigeration circuit must be A2L certified. Example: Evaporator and Expansion Valve.
For PED Cat I models: Pressure relief valve shall be mounted in refrigerant system during field installation. PRV should be mounted on receiver vessel.
For PED Cat II models: Pressure Pressure relief valve is factory fitted with Condensing unit on liquid receiver with 34.5 ± 1 bar pressure setting. (See section 3.1 - PRV valve)
Operation of Receiver Rotolock valve should be operated by trained/skilled professional operator. Make sure all rotolock valves are open during CU operation.

2 – Handling and storage
• Do not braze as long as the condensing unit is
under pressure.
• A2L refrigerants are heavier then air, hence
Danfoss recommend to install above ground
level. Refer Annex - A
• It is recommended not to open the packaging
before the unit is at the final place of 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.
• Store the unit between -35°C and 50°C.
• Don't expose the packaging to rain or corrosive
atmosphere.
• After unpacking, check that the unit is complete
and undamaged.
3 – Installation precautions
Do not braze as long as the
condensing unit is under pressure.
Place the unit in such a way that it
is not blocking or hindering walking
areas, doors, windows or similar.
A2L refrigerants are heavier than air.
Unit has to be installed above floor
level to have a good compressor
compartement ventilation.
PRV: In PED Cat II models, PRV comes
with installed. For PED Cat I models,
PRV shall be mounted at field during
installation.
• Ensure adequate space around the unit for air
circulation and to open doors. Refer to Annex - A
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 (use grommets, pads or support) and
interference.
• The unit ambient temperature may not exceed
63°C during off-cycle.
• Ensure that the power supply corresponds to the
unit characteristics (see nameplate).
• When installing units for R454C, R455A and
R1234yf refrigerants, use equipment specifically
reserved for A2L refrigerant which was never
used for other HFO, CFC or HCFC refrigerants.
• Use clean and dehydrated refrigeration-grade
Copper / Aluminium tubes with appropriate
thickness 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
