Safety Awarenes
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
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.
Unpacking Inspection
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.
Inspection on Installation Environment
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
Safety Principles of Installation
1. Favorable ventilation shall be maintained at the place of installation (doors and windows are opened).
2. Open fire or high-temperature heat source (including welding, smoking and oven) higher than 548
the scope of flammable refrigerant.
3. Anti-static measures shall be taken, such as the wearing of cotton clothes and cotton gloves.
4. The place of installation shall be convenient for installation or maintenance. Barriers shall be avoided around the air
inlet/outlet of the indoor/outdoor unit, and the electrical appliance, power switches, sockets, valuables and high-temperature
products within the scope of both sidelines of the indoor unit shall be avoided, and cannot be adjacent to heat source and
flammable and combustible environment.
5. In case of refrigerant leakage of the indoor unit during installation, the valve of the outdoor unit shall be closed immediately,
and windows shall be opened, and all the personnel shall be evacuated. After the leakage of refrigerant is handled, the indoor
environment shall be subject to concentration detection. Further handling is not allowed until the safety level is reached.
6. In case the product is damaged, it must be delivered to the maintenance point. Welding of refrigerant pipelines at the user's
site is not allowed.
