FAQ
Q. What size diameter are the Shinco mini split air conditioners line sets?
Q: When moving the Shinco split air conditioner system, how can I save the R410 refrigerant gases?
- Turn on your air conditioner system and set it on cooling mode.
- Remove valve core copper caps of high & low pressured valves.
- Turn off valve core of high pressured valve. (thicker line)
- Keep the air conditioners running for 3 minutes? Please ensure that compressor is operating.
- Turn off core valve off low pressured valve (thinner line)
- Turn off air conditioner by remote and turn off power supply.
Q: Why is does the line set between the indoor and outdoor unit frost up?
Your unit is lacking R410 refrigerant gases. Please verify pressure and make sure amount is sufficient for the distance between units. You can download and view the following chart that explains exactly how much gas is required in according to the distance separating the two unit of your split air conditioner.

Q: Why does my split air conditioner blow colds air while in heating mode?
If the outside temperature is below a certain point when you start up your unit, the compressor will initially run in defrost mode to avoid damage to your unit. Once the compressor heats up, it will automatically switch to heating mode. This procedure takes around 10 minutes.
Q: Why does the indoor fan run at a low speed and why is the green light flash during heating mode?
A: When air conditioner runs on anti- cold air mode, the green light flashing, and process see below:
During heating mode, the temperature of room and evaporator is low, to avoid cold air blowing, the indoor unit runs in anti-cold air mode. When the evaporator temperature is below 15℃, the indoor motor doesn’t run, the outdoor unit runs. When the evaporator temperature is between 15℃ and 30℃, the indoor motor runs in breeze (lower than low speed),
On anti-cold mode, outdoor unit keep running, so evaporator temperature rise rapidly. When the evaporator temperature rise to 26℃, the indoor motor runs in breeze, when rise to 30℃, the indoor motor runs in low speed, when rise to 34℃, the motor runs in medium speed, when the evaporator temperature is increased to 38℃,the indoor motor runs in the set speed.
Q: What to do if the green light flashes for long time?
A: The indoor pipe sensor needs to be changed. Due to defective of pipe sensor, the air conditioner can’t get right information from pipe sensor, and the green light flashed all time.
Q: How to know if the compressor starts?
Press ‘lock’ button on remote controller 6 times within 10 seconds, there will display H1 value in indoor panel, check H6, if it’s not 0, the compressor starts.
Q: How to know if the refrigerant is absent?
Press ‘lock’ button on remote controller 6 times within 10 seconds, there will display H1 value in indoor panel, check H8 and H6. H6 is compressor electricity and H8 is compressor frequency.
If H8 is above 50 and keep no change, however, H6 is much lower than rated current, as below table, half or less, it means refrigerant is absent.
Q: What can you do if have no 240V outlets and a 240V air conditioner to plug in?
A: You'll have to install a double-pole breaker in your breaker box. As for the outlet, read the instructions and determine what size outlet (how many amps) you need. If it just requires 240V you'll need a 3 conductor wire. (2 wires plus ground.).
Q: How often should you change the filter on your heating and AC unit?
A: It all depends where you live - what the air pollution levels are in your area - and what kinds of pollutants you use inside your house. You should at least look at your filter every 30 days and change same if necessary. If clean, check at least every 45 days.
Q: What does the abbreviation 'HVAC' mean?
A: Heating, Ventilation, and Air-Conditioning
Q: What would cause the outside part of your air conditioner to frost over?
A: Because of high humidity in the air, the evaporator gets cold enough to cause the extra moisture to freeze. This could happen if you are low on refrigerant or if your coils or filters are dirty. If you are low on Freon, you most likely have a leak and should hire a professional to fix this. A temporary fix is simply to turn off the unit until it warms up/thaws. Then turn it back on. But this is not a permanent solution. Clean any dirty coils or filters and if this doesn't fix the problem, have a professional check for leaks and refrigerant levels.
Q: What is the correct pressure on the high side and the low side of an efficiently working system?
A: High side <200psi. Low side <50 lb.
"A good rule of thumb with R410a is to run fan on High with all windows open and engine at 1500 rpm. High side pressure in PSI should be about 2.2 to 2.5 times outside air temperature in degrees F". There are NO easy answers to this. Shinco provide a chart or charts that will assist in determining what those pressures will be. The variables that will affect those pressures include, but are not limited to: Outdoor ambient temperature Outdoor relative humidity Indoor entering temperature, Unit sizing and proper airflow through system .
Q: What is SEER rating
A: Seasonal Energy Efficiency Ratio (SEER) — A measure of seasonal or annual efficiency of a central air conditioner or air conditioning heat pump. It takes into account the variations in temperature that can occur within a season and is the average number of Btu of cooling delivered for every watt-hour of electricity used by the heat pump over a cooling season.
Q: What causes the evaporator to freeze?
A: The evaporator may be dirty or the condenser (outside unit) may be dirty. You may be low on "Freon", indicates a possible leak. Check the filter.
Q: Why condensed water blowing out from indoor unit?
The end of drain hose of indoor unit must be even with the other end, or a little lower than other end, to let condensed water drain freely.
Q: Why smell blowing out from indoor unit?
The indoor filter needs to be washed every three months, or the dirt will accumulate on the filter and smell is blown with air.
Q: Why we hear sound of flowing liquid?
The refrigerant is flowing inside of the pipes.
Q: Why we hear clicking sounds from indoor plastic parts?
Plastic expands with heat and contracts with cold.
Q: How does air conditioner run with Auto restart mode?
Should there be a power failure whilst the unit is operating, when the power is restored, it will automatically return to the same operating conditions settings prior to the power failure.
