Fan Motor - Danfoss Optyma Slim Pack OP-LSVM Serie Instrucciones

Instructions
• Installer need to take care of where to blow the
leaked refrigerant. Danfoss recommended to
blow refrigerant away form condensing unit.
• Recommended to change PRV when after
discharge, Changing refrigerant.
• Don't remove the seal and attempt to reset the
valve.
• Valves must be installed vertically or Horizontally,
but ensure PRV to be fitted above system's liquid
level.
• Ensure refrigerant is released safely to
atmosphere directly.
• Incase of hazard, additional spare kit has
been designed in order to collect the released
refrigerant. Kit should be installation with proper
piping routing for discharge of refrigerant safely.
(See picture below)
• PRV should not be installed on service valve.
• Replace PRV after clean out of system or bared
out.
• No Detachable joints and valves should not
accessible to public. All brazing joints should
comply with EN 14276-2 and other permanent
joints should comply with EN-16084.
4 – Installation
• Installation/servicing of Optyma™ Slim Pack
condensing units must be carried out by qualified
personnel with respect to
international regulation.
• The installation in which the condensing unit is
installed must comply to EC Pressure directive
(PED) no. 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, and fixed from the beginning.
See Annex-A, Picture 2.
• 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. Refer image Annex-A,
Picture 3.
• 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 dummy cap.
• It is recommended to insulate the suction pipe
from evaporator up to the compressor inlet with
19 mm thick insulation.
• Make sure there is no refrigerant or damage inside
unit and crack in pipes.
• Make sure that all components inside electrical
box are protected against electrical overload

and ''not source of ignition'' from its respective
manufacturer for approved refrigerants.
• Field wiring must be routed through IP65
cable glands and cable entry plate only. For
any additional wire routing, drilling or piercing
electrical panel sides strictly prohibited.
• For field wiring, only required hole to be pierced.
No pierced hole should be left without cable in it.
If undesired/unwanted piercing happens entire
gland plate should be replaced.

the
• Partition panel has dedicated openings for
pre ventilation, do not seal/obstruct/close the
openings in any manner.
• In the event of uncertain leakages, To avoid
refrigerant
compartment, compressor has a on-time delay
of 30 seconds (factory setting) do not reduce the
setting below 30 seconds.
• Copper piping material should comply with
EN12735-1. And all pipe joints should comply
with EN14276-2
• At filed installation, support to added according
to size and weight. Recommended maximum
spacing for pipe support as per EN12735-1 &
applicable local/
EN12735-2
• Connecting pipes shall be made before opening
the valves to permit refrigerant to flow between
the refrigerating system parts.
5 – Leak detection
• Do not use dye for leak detection.
• Perform a leak detection test on the complete
system.
• The maximum test pressure is 25 bar.
• When a leak is discovered, repair the leak and
repeat the leak detection.
6 – Vacuum dehydration
• Never use the compressor to evacuate the system.
• Connect a vacuum pump to both the LP & HP
sides.
• Vacuum pump must be certified to use in A2L
refrigerant environment or ATEX certified.
• Pull down the system under a vacuum of 500 μm
Hg (0.67 mbar) absolute.
• Do not use a megohmmeter nor apply power to
the compressor while it is under vacuum as this
may cause internal damage.
7 – Electrical connections
• Verify that all electrical connections inside the
condensing unit are properly fastened as they

Never pressurize the circuit with
oxygen or dry air. This could cause
fire or explosion.
could have worked loose during transportation.
• Switch off and isolate the main power supply.
• Ensure that power supply can not be switched on
during installation.
• All electrical components must be selected per
EN60335-1, EN60204 or local applicable standard
and unit requirement.
• Refer to wiring diagram for electrical connections
details.
• All electrical components must be qualified to use
A2L refrigerants and ''not source of ignition'' .
• Ensure that the power supply corresponds to the
unit characteristics and that the power supply is
stable (allowable voltage tolerance ±10% and
allowable frequency tolerance ±2,5 Hz).
• The power supply cables must be according
to unit data for voltage, current and ambitent
condition. Refer Nameplate for voltage and
current information.
• Protect the power supply and ensure correct
earthing.
• Optyma™ Slim pack condensing unit starting
frequency need to be limited for reciprocating
compressors
- Without starting capacitor 5 starts per hour
maximum.
- With starting capacitor 10 starts per hour
maximum.
• Make the power supply according to local
standards and legal requirements.
• The unit is equipped with high and low pressure
switches, which directly cuts the power supply
to the compressor and provides 230V AC alarm
signals (max. 50VA) in case of activation (Alarm
signal wirings must be done on field. Refer wiring
diagram for more details). Parameters for high and
low pressure cut outs should be set by installer
considering compressor model, refrigerant and
application.
• Determine the phase sequence by using a phase
meter in order to establish the phase orders of
line phases L1, L2 and L3.
• Connect line phases L1, L2 and L3 to main switch
terminals T1, T2 and T3 respectively.
• Timer should have minimum setting of 30 sec for
pre ventilation. Rotate clockwise and set arrow to
30s marking or above (refer below image)
• B3 units (both W05 & W09 versions) assembled
with EC fan Motor are
Potentiometer of 10kohms (refer below image
and wiring diagram). These are factory set for Fan
to rotate at 80% speed. This is done to restrict the
Noise emission and suitable to operate at 43°C
Ambient. If the Fan speed to be increased, rotate
the Potentiometer setting in clockwise direction.
