Instructions
Optyma™ Plus
OP-MPS, OP-MPT, OP-LPV 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.
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 installation, 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.
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 mildly flammable 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.

1 – Introduction
These instructions pertain to Optyma™ Plus
condensing units OP-MPS, OP-MPT, OP-LPV and
OP-MPI used for refrigeration systems. They
provide necessary information regarding safety
and proper usage of this product.
The condensing unit includes following:
• Microchannel heat exchanger
• Reciprocating or scroll compressor
• Receiver with stop valve
• Ball valves with schrader Valve
• Sight glass (Flare connections)
• Suction and Discharge Pressure transducers
• High & low pressure switches
• Filter drier (Flare connections)
• Electronic controller
• Main circuit breaker (Main switch with overload
protection)
• Fan and compressor capacitors
• Compressor contactor
• Robust weather proof housing
• IP54 Fully pre-wired electrical panel
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 for
installation.
• Handle the unit with care. The packaging
2 | AN37261897352601-010201 - 118A2177B
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.
It's not allowed to operate the unit in
flammable atmosphere.
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.
• 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
50°C during off-cycle.
• Ensure that the power supply corresponds to
the unit characteristics (see nameplate).
• When installing units for R454C, R455A
&
R1234yf
refrigerants,
use
specifically reserved for mildly flammable
refrigerant which was never used for HFO, CFC
or HCFC refrigerants.
• Use clean and dehydrated refrigeration-grade
copper tubes with appropriate thickness and
silver alloy brazing material.
• Use clean and dehydrated system components.
• The
suction
piping
connected
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.
4 – Installation
• Installation/servicing
of
condensing units must be carried out by
qualified personnel with respect to applicable
local/international regulation and with the
correct user Personal Protective Equipment
(PPE).
• The installation in which the condensing unit is
installed must comply to pressure Equipment
Directive (PED) 2014/68/EU. The condensing
unit itself is not a "unit" in the scope of this
directive.
• The unit must be securely installed on a stable
and rigid support. Refer Annex - A.
