Heat Insulation; Test Running; Precautions In Test Run; Check The Following Items When Installation Is Complete - LG MT06AH Instruction Manual

HEAT INSULATION

1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resis-
tance (over 120°C).
2. Precautions in high humidity circum-
stance:
This air conditioner has been tested
according to the "KS Standard
Conditions with Mist" and confirmed that
there is not any default. However, if it is
operated for a long time in high humid
atmosphere (dew point temperature:
more than 23°C), water drops are liable
to fall. In this case, add heat insulation
material according to the following pro-
cedure:
• Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20mm.
• Stick glass wool on all air conditioners that are located in ceiling atmosphere.

Test running

1. PRECAUTIONS IN TEST RUN

• The initial power supply must provide at least 90% of the rated voltage.
Otherwise, the air conditioner should not be operated.
① For test run, carry out the cooling operation firstly even during heating
CAUTION
② Carry out the test run more than 5 minutes without fail.
• The test run is started by pressing the room temperature checking button and down timer button
for 3 seconds at the same time.
• To cancel the test run, press any button.

CHECK THE FOLLOWING ITEMS WHEN INSTALLATION IS COMPLETE

• After completing work, be sure to measure and record trial run properties, and store measured
data, etc.
• Measuring items are room temperature, outside temperature, suction temperature, blow out tem-
perature, wind velocity, wind volume, voltage, current, presence of abnormal vibration and noise,
operating pressure, piping temperature, compressive pressure.
• As to the structure and appearance, check following items.
□Is the circulation of air adequate?
□Is the draining smooth?
□Is the heat insulation complete
(refrigerant and drain piping)?
□Is there any leakage of refrigerant?
season. If heating operation is carried out firstly, it leads to the trouble
of compressor. Then attention must be paid.
(Test run will be cancelled 18 minutes later automatically)
Indoor unit
□Is the remote controller switch operated?
□Is there any faulty wiring?
□Are not terminal screws loosened?
