Safety
Unpacking Inspection
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.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.
2.Power supply, switches or other high-temperature articles such as the fire source and oil heater shall be avoided below
the indoor unit.
3.The power supply shall be provided with earthing wire and be reliably earthed.
4.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 is not allowed
within 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 the product is damaged, it must be delivered to the maintenance point. Welding of refrigerant pipelines at the
user's site is not allowed.

Electrical Safety Requirements
1.The surrounding conditions (ambient temperature, direct sunlight and rainwater) shall be noticed during electrical wiring,
with effective protective measures being taken.
2.Copper wire cable in line with local standards shall be used as the power line and connector wire.
3.Outdoor unit shall be reliably earthed.
4.The dedicated branch circuit must be used, and leakage protector with sufficient capacity must be installed.
