Part II
1. Service warning
Part I General Warnings
1、The service person should wear safety belt if working more than 2.5m above the ground.
2、If working above ground level, measures should be adopted to prevent the outdoor unit or tools
from falling and causing injuries or damage.
3、Check the customers power supply before testing the unit.
4、The power supply should be switched OFF when disassembling the casing and electrical
components.
5、Take care to prevent a frost bite injury when charging with refrigerant.
6、Do not over pressurize the Freon cylinder. The over exposure, high temperature or dropping the
cylinder should be avoided, otherwise, it could cause an explosion.
7、If there is need to pressure test the system, Dry Nitrogen should be used.
Part II Warnings of repair operation
1、
The high capacity electrolytic capacitor is used in the electric control cabinet of the outdoor unit.
Even if the power plug is unplugged; this capacitor will retain a residual charge for a certain time. In
order to avoid electric shock, please do not touch the control board as soon as the power is switched
OFF. If it is necessary to change the control board of the outdoor unit, please switch OFF the power
supply first. After the light emitting diode of outdoor control board extinguishes or the power is
switched OFF for >30 sec’s, let the high capacity capacitor discharges fully. The replacement can
only be conducted after checking the high capacity capacitor has discharged fully with an electrical
meter.
2、
After making use of self-diagnosis of faults on the site, switch the snap switch to “demonstrate”,
re-electrify the air-conditioner so that the system can erase the stored fault information of former
self-diagnosis. Switch the snap switch to “ON” again, prepare for re-starting the air-conditioner.
Because the LS-LT1508V model air-conditioner has not been fitted with an E2PROM (storage
device of fault information), the fault information will be automatically erased after switching OFF
the power.
3、
For diagnosis of the system fault, first it is suggested to check whether the electrical wiring is
reliable and correct. After eliminating this cause, continue to seek other causes.

When outdoor current is higher than I1, the compressor frequency will be limited and prohibited to rise. When the
current is higher than I2, and the compressor frequency will lower until the current is lower than I1.
When outdoor current is lower than I3, the compressor will stop.
The detailed current value see below table:

5.3 Low voltage protection
The compressor frequency changes as following fig. during low voltage：
When voltage value lower than 190V and keep for 10s, the low voltage protection start,
and when voltage value rise to 195V and keep for 10s, the low voltage proteccion finish.
When voltage value lower than 158V, the unit turn off, when voltage rise to 162V, keep
for 10s, the unit restart.
