WARNING
●
Optional parts mush be installed by professionals. Be sure to use the optional parts provided by TRANE.
Improper installation can lead to water leakage, electric shock and re.
●
Please do not charge unqualied refrigerants, refrigerant substitutes or refrigerant additives. Incorrect charge
methods or charge of unqualied refrigerants, refrigerant substitutes or refrigerant additives will cause unit
damage and safety hazards. Please select qualied refrigerants. All technicians charging refrigerants must
be qualied and must be familiar with and strictly comply with the relevant technical requirements, laws and
regulations regarding the use, treatment, recovery and recycling of refrigerants
●
Smoking and re are strictly prohibited when refrigerant leaks. If the unit does not produce cool or heat properly,
there may be refrigerant leakage and please contact TRANE after-sales
●
The refrigerant used in the unit is safe and usually the leaks possibility is very low. If the refrigerant leaks into
indoors, and the refrigerant gets contact with pyrotechnics of heaters, electric stoves, and heaters, toxic gases
will be generated. Please make sure to extinguish the re of burning appliances or other appliances that may
cause re, ventilate the room and contact Trane after-sales.
●
Please conrm that the leakage repair is actually completed before running the unit.
●
Do not turn on the unit when the panel or protective net is removed. Rotating parts in the unit may cause injure
of human body or other objects.
●
Avoid objects such as sticks, sands, or stones to enter the inlet or outlet of grilles. The fan rotating at high
speed is very dangerous.
●
The strength of ordinary unit bracket may not be suitable for this product, please choose suitable bracket
according to the design weight. Using of brackets with insu󰀩cient supporting strength may bring hidden
dangers or even cause safety accidents.
●
In winter, when the unit was stopped for a short time, make sure to keep the unit powered on to protect the unit
free of frozen. Otherwise, the unit may freeze out.

CAUTION
●
Do not touch the ns of the heat exchanger. It may damage the ns, cause machine performance degradation or
scratch ngers.
●
After installation, air leakage for the pipeline needs to be tested to make sure there’s no leak for the pipeline.
●
During running or short period after unit stops, do not touch refrigerant pipes. The pipes can be too hot or too
cold to cause burns or cold injury.
●
Do not block or cover the inlet or outlet of grilles. The blockage will result in degraded performance or impact
unit operation.
●
There should be a defrost drainage port to ensure the smooth drainage.
●
It is recommended to install an outdoor snow shelter to ensure that the unit can run well on snowy days
