Installation Instructions
1. Procedures: operation shall be made as per controlled procedures to minimize the probability of risks.
2. Area: area shall be divided and isolated appropriately, and operation in an enclosed space shall be avoided.
Before the refrigeration system is started or before hot working, ventilation or opening of the area shall be
guaranteed.
3. Site inspection: the refrigerant shall be checked.
4. Fire control: the fire extinguisher shall be placed nearby, and fire source or high temperature is not allowed;
the sign of “No smoking” shall be arranged.
1. Indoor unit: nitrogen is sealed during the delivery of indoor units (inside the evaporator), and the red sign at
the top of the green plastic seal cap on the evaporator air pipes of the indoor unit shall be checked first after
unpacking. In case the sign is raised, the nitrogen sealed still exists. Afterwards, the black plastic seal cap at the
joint of evaporator liquid pipes of the indoor unit shall be pressed, to check whether nitrogen still exists. In case
no nitrogen is sprayed out, the indoor unit is subject to leakage, and installation is not allowed.
2. Outdoor unit: the leak detection equipment shall be extended into the packing box of the outdoor unit, to
check whether the refrigerant is leaking. If the refrigerant leakage is identified, installation is not allowed, and the
outdoor unit shall be delivered to the maintenance department.
1. The room area checked cannot be less than the area specified on the warning sign of the indoor unit.
2. Inspection on the surrounding environment of place of installation: the outdoor unit of flammable
refrigerants air conditioner cannot be installed inside an enclosed room reserved.
3. Power supply, switches or other high-temperature articles such as the fire source and oil heater shall be
avoided below the indoor unit.
4. The power supply shall be provided with earthing wire and be reliably earthed.
5. While punching the wall with an electric drill, whether embedded water/electricity/gas pipelines are
designed at the hole preset by the user shall be verified in advance. It is recommended that the through-wall holes
reserved shall be used as much as possible.
