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.

One of the standout features of the Shinco BM series is its impressive energy efficiency rating, which helps to reduce electricity bills while still delivering powerful cooling and heating performance. The models are equipped with advanced inverter technology that allows for variable speed operation. This means that rather than cycling on and off entirely, the compressor adjusts its speed according to the required cooling or heating load. This not only results in a more consistent temperature but also extends the lifespan of the unit.

The KFR-25GWZ model integrates a multi-stage filtration system that ensures cleaner air quality. This system effectively captures dust, allergens, and other airborne particles, promoting a healthier indoor environment. Additionally, these units often feature a self-cleaning function which helps maintain the cleanliness of the internal components, enhancing efficiency and longevity.

User-friendly interfaces are another hallmark of the Shinco series. The remote control and optional Wi-Fi connectivity allow users to monitor and adjust settings from their smartphones or tablets. Features like programmable timers, sleep modes, and multiple fan speeds further enhance convenience.

In terms of design, the KFR-25GWZ is both sleek and modern, making it a perfect fit for various interior aesthetics. Its compact design ensures that it can be installed in a range of spaces without being obtrusive.

The noise levels of both the BM and KFR-25GWZ units are impressively low, making them suitable for bedrooms, offices, and other areas where quiet operation is essential. Enhanced insulation within the units minimizes sound, allowing users to enjoy their space without distraction.

Safety features including automatic restart after a power outage and overcurrent protection make these air conditioners reliable choices for households and businesses alike. Additionally, the environmentally friendly refrigerants used in these models contribute to lower global warming potential, aligning with contemporary sustainability goals.

In conclusion, the Shinco BM and KFR-25GWZ series showcase a blend of innovative technology, energy efficiency, and user-friendly features, making them an excellent choice for those looking to enhance their indoor comfort in a sustainable way.
