Refrigerant Charge Limit Max 2,500g
(Charge limit depends on Oil Dilution Rate**note 2 & accumulator ‘K’)
Liquid Refrigerant Back
System should be designed not to allow the liquid to go back to
compressor which cause knocking noise , current increase or
undesirable vibration and make short compressor life time.
Δ T : Temp. Difference Δ T = Case Bottom Temp.－ Condensing Temp.
It must be kept Δ T ≥ 5℃
Pressure Difference
in Operating
The Pressure difference in operating shall be 5.0㎏f/㎠ or more,
but 3 minutes starting excluded.
ON/OFF Operation Each cycle should be at least 6 minutes
(ON Time : at least 3 minute , OFF Time : at least 3 minutes)
3.2 Application Limit
※This guide contains many important safety messages. Always read and obey all safety messages.
You can be killed or seriously injured if you don’t follow instructions.
Page 9 / 24GVH2 2PAB
(ON Time : at least 3 minute , OFF Time : at least 3 minutes)
Pressure Difference
at Starting
When starting, discharge pressure is balanced with suction pressure.
( Pd – Ps ≤ 0.5 ㎏f/㎠ )
Tilt in Operation The allowable tilt of the compressor in operation shall be 5˚ or less.
System Accumulator
The Accumulator volume should be enough to cover 50% of
maximum system refrigerant volume.
Ratio coefficient ‘K’ should be over 0.6(heating system) or 0.4(cooling
system)
Effective Volume of Accum. × Specific gravity of Refrigerant
K = --------------------------------------------------------------------------
Charged Weight of Refrigerant
※ Effective Volume of Accumulator = 580 ㎤
※ Specific Gravity of Refrigerant (R410A) = 1.085 g/㎤ ( at 20℃ )
If coefficient “K” does not meet recommendation, refrigerant system
must check liquid back phenomenon at accumulator.
Protecting Reverse
Operation
The compressor must be operated by proper voltage in accordance
with the frequency without reverse revolution condition. The reverse
revolution condition can be avoided by just keeping right order of
phase supplied power source.

LGETH -180704-054 / Rev. 0LG Electronics
Frequency Range Rated Frequency ±2%
Pipe Stress Don’t allow any force on discharge & suction pipe .
The piping stress must be less than 300㎏f/㎠at starting and stopping.
And less than 153㎏f/㎠at running.
Oil Level It must be checked oil level by the compressor with
sight glass we supply. And oil level must be kept over
guide line level **note 3. at any condition.
Protection device Refrigeration system must has the compressor protection device like
over pressure, high temperature, sensing locked pump in the controller.
When starting & running fail by abnormal overload, controller must be
able to cut off power of compressor before motor burn out.
An earth terminal should be installed to prevent electrical accidents.
3.2 Application Limit
Page 10 / 24GVH2 2PAB
Pump down
refrigerant
If pump down time is too long, compressor can be damaged due to
excessive temperature increase or poor lubrication.
Guideline of pump down process.
- Time : less than 30 seconds
- Suction Pressure : It should not run under below 1㎏f/㎠G.
And before closing a service valve, compressor running for more than 5
minutes is recommended.
※If gas charge amount of refrigerant specified is exceeded,
both parties should discuss the matter to determine compressor specification.
(accumulator volume, lubricating oil amount) and system specifications (crank case
heater, oil separator , additional accumulator, etc)

Use defined Refrigerant
and oil
Any process in where the HCFC’s refrigerant or the
different kind of oil against the defined. Compressor oil
are mixed should be avoided.
Avoid Damage running The running operation that inspection and the protector
inspection that affect a damage to the function and
durability of the compressor should be avoided
Running dummy indoor When the outdoor unit is operated with the indoor
dummy unit, the discharged oil should be recovered
enough
Prevent oxidation in pipe Always purge the system and the compressor with the
dry nitrogen in order to prevent oxidation of the piping
Charging Refrigerant When charging refrigerant into the cycle, make sure that
refrigerant always be filled from the higher pressure side
(condenser exit) of the cycle.
If liquid refrigerant is sucked in to the compressor liquid
compression occurs, The discharge valve is damaged,
lubrication effectiveness degenerates and reliability drops
3.3 Process Limit
Page 11 / 24GVH2 2PAB
lubrication effectiveness degenerates and reliability drops
noticeably
Avoid Vacuum running Do not operate the compressor in a vacuum state.
Furthermore do not apply high voltage to a vacuum state
compressor. There is a danger that insulation could
degenerate, causing electric shock
Avoid Air compression Do not compress the air including the case of leakage in
the refrigeration cycle. If compressors run with air mixed,
inside the compressor is heated and pressurized , which
may cause an explosion
Promptly Assemble
compressor in line
After removing rubber plugs from compressor tubes,
Promptly use the compressor. And do not leave in the
atmosphere for 10 minutes over. If Air gets into the
compressor , accelerating degeneration of the inside of
the cycle or compressor
Wiring Wires connected to the compressor, follow the
compressor specification manual and instructions
Storage temperature -10℃ ~ 65℃
Earth connection Use compressor with grounded system only.
