1 – Introduction
These instructions pertain to the Performer® HRM/
HLM/HCM HRP/HLP/HCP/HHP HRH/HLH/HLJ/
HCJ scroll compressors used for HVAC systems. They
provide necessary information regarding safety and
proper usage of this product.
2 – Handling and storage
• Handle the compressor with care. Use the dedicated
handles in the packaging. Use the compressor lifting
1 2
lug and use appropriate and safe lifting equipment.
• Store and transport the compressor in an upright
position.
• Store the compressor between -35°C and 70°C /
-31°F and 158°F.
• Don’t expose the compressor and the packaging
to rain or corrosive atmosphere.
3 – Safety measures before assembly
Never use the compressor in a flammable atmosphere.
• Mount the compressor on a horizontal flat surface with less than 7° slope.
• Verify that the power supply corresponds to the
compressor motor characteristics (see nameplate).
• When installing a compressor model HRP / HLP /
HCP / HHP - HRH / HLH /HLJ / HCJ, 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.

Instructions
• Use clean and dehydrated system components.
• The piping connected to the compressor must be
flexible in 3 dimensions to dampen vibrations.
• The compressor must always be mounted with the
rubber grommets supplied with the compressor.
4 – Assembly
• Slowly release the nitrogen holding charge
through discharge and suction ports.
• Connect the compressor 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, if any, is used for this, remove the internal valve.
• For parallel assemblies of the compressors in version C8, contact Danfoss.
5 – Leak detection
Never pressurize the circuit with oxygen or dry
air. This could cause fire or explosion.
• Do not use leak detection dye.
• Perform a leak detection test on the complete system.
• The low side test pressure must not exceed 31 bar
/450 psi.
• 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.
• Pull down the system under a vacuum of
500 µm Hg (0.67 mbar) / 0.02 inch Hg 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
• Switch off and isolate the main power supply.
• All electrical components must be selected as per local
standards and compressor requirements.
• Refer to page 1 for electrical connections details.For
three phase applications, the terminals are labeled T1,
T2, and T3. For single-phase applications the terminals
are labeled C (common), S (start), and R (run).
• Danfoss scroll compressors will only compress gas
while rotating counter-clockwise (when viewed from
the compressor top). Since single-phase motors will
start and run in only one direction, reverse rotation is
not a major consideration. Three-phase motors, however, will start and run in either direction, depending on
the phase angles of the supplied power. Care must be
taken during installation to ensure that the compressor operates in the correct direction.
• Use ø 4.8 mm / #10 - 32 screws and ¼” ring terminals
for the power connection with ring connect screw terminal (C type). Fasten with 3 Nm torque.
• Use ø 6.3 mm tabs for quick connect spade terminals (P type).
• Use a self tapping screw to connect the compressor to earth.
8 – Filling the system
• Keep the compressor switched off.
• Keep the refrigerant charge below the indicated
charge limits if possible. Above this limit; protect
the compressor against liquid flood-back with a
pump-down cycle or suction line accumulator.
• Never leave the filling cylinder connected to the circuit.

9 – Verification before commissioning
Use safety devices such as safety pressure
switch and mechanical relief valve in compliance
with both generally and locally applicable regulations and safety standards. Ensure that they are
operational and properly set.
Check that the settings of high-pressure switches don’t exceed the maximum service pressure
of any system component.
• A low-pressure switch is recommended to avoid
low pressure operation.
Minimum setting for R22
Minimum setting for R407C
Minimum setting for R410A 2.5 bar (absolute) / 36 psia
1.5 bar (absolute) / 22 psia
• Verify that all electrical connections are properly faste-
ned and in compliance with local regulations.
• When a crankcase heater is required, it must be
energized at least 24 hours before initial start-up
and start-up after prolonged shutdown.
10 – Start-up
• Never start the compressor when no refrigerant is
charged.
• Do not provide any power to the compresor
unless suction and discharge service valves are
open, if installed.
• Energize the compressor. It must start promptly.
If the compressor does not start, check wiring
conformity and voltage on terminals.
• Eventual reverse rotation can be detected by following
phenomena; the excessive noise, no pressure differential between suction and discharge, and line warming
rather than immediate cooling. A service technician
should be present at initial start-up to verify that supply power is properly phased and that the compressor
is rotating in the correct direction. H-series Scroll compressors are designed to operate for a maximum of
150 hours in reverse, but as a reverse rotation situation
can go unnoticed for longer periods, phase monitors
are recommended. For compressors HLM078, HLP081,
HLJ083 and larger, phase monitors are required for all
applications. Danfoss recommends phase protection
for residential compressors.
• If the internal overload protector trips out, it must cool
down to 60°C / 140°F to reset. Depending on ambient
temperature, this may take up to several hours.
11 – Check with running compressor
Check current draw and voltage. Measurement
of amps and volts during running conditions must
be taken at other points in the power supply, not in
the compressor electrical box.
• Check suction superheat to reduce risk of slugging.
H series
• Observe the oil level in the sight glass (if provided) for about 60 minutes to ensure proper oil
return to the compressor.
• Respect the operating limits.
• Check all tubes for abnormal vibration. Movements in excess of 1.5 mm / 0.06 in require corrective measures such as tube brackets.
• When needed, additional refrigerant in liquid phase
may be added in the low-pressure side as far as possible from the compressor. The compressor must be
operating during this process.
• Do not overcharge the system.
• Never release refrigerant to atmosphere.
• Before leaving the installation site, carry out a
general installation inspection regarding cleanliness, noise and leak detection.
• Record type and amount of refrigerant charge as
well as operating conditions as a reference for future inspections.
12 – Maintenance
Internal pressure and surface temperature are
dangerous and may cause permanent injury. Maintenance operators and installers require appropriate skills and tools. Tubing temperature may exceed
100°C / 212°F and can cause severe burns.
Ensure that periodic service inspections to ensure system reliability and as required by local regulations are performed.
To prevent system related compressor problems, following periodic maintenance is recommended:
• Verify that safety devices are operational and pro-
perly set.
• Ensure that the system is leak tight.
• Check the compressor current draw.
• Confirm that the system is operating in a way
consistent with previous maintenance records
and ambient conditions.
• Check that all electrical connections are still ade-
quately fastened.
• Keep the compressor clean and verify the absen-
ce of rust and oxidation on the compressor shell,
tubes and electrical connections.
• Acid / moisture content in system and oil should
be checked regularly.
