  • Page 18: Outdoor Piping Installation

    9. Outdoor Piping Installation 9.1 Product features • The outdoor uint adopts "simultaneous control" type, all indoors should be heating or cooli.ng simultaneously. • To protect compressor,before startup,the unit should be electrified for 12 hours.If the unit is not used for a long time, please cut off the power to save energy, or the unit will consume the power.
  • Page 19 • The maintenance cover plate of the indoor or outdoor machine is forbidden when the main circuit power supply is not cut off. • The leakage of refrigerant can cause the air to be thin and difficult to breathe. In case of refrigerant leakage, close the main valve, extinguish any flame and contact the local distributor immediately.

  • Page 20: Transportation And Lifting

    Arrival inspection • After receiving the machine, should check whether there is transport damage. If any damage is found on the surface or inside, it shall be reported immediately to the shipping company in writing. • Check the product model, electrical parameters (power supply, voltage, frequency) and accessories to determine whether they meet the requirements.

  • Page 21: Installation Instruction

    9.4 Installation instruction In installation, please check specially the below items: • If the connected units quantity and the total capacity is in the allowable range? • If the refrigerant pipe length is in the limited range? • If the pipe size is proper? And if the pipe is installed horizontally? •...

  • Page 27 Note: 1. When connecting the pipe and the outdoor, please pay attention to the outdoor pipe dimension. 2. When adjusting the diameter among pipes and among the units, please must execute at the branch pipe side. 3. When welding with hard solder, please must blow nitrogen. If not, a number of oxide will be produced and cause heavy damage.Besides,to prevent water and dust into the pipe, please make the brim as outer roll.
  • Page 28 • The outdoor gas pipe and the refrigerant distributing pipe, as well the refrigerant distributing pipe and the branch pipe should be welded with hard solder. • Weld the pipe at the same time charge the nitrogen. Or it will cause a number of impurity (a film of oxidation) to clog the capillary and the Seal the pipe end with expansion valve, further cause the deadly failure.
  • Page 29 Because the unit is with refrigerant R410A, the below issues should be paid attention: • To prevent the different oil into the pipe, please use the special tool for R410A, especially for gauge manifold and charging hose. • To prevent the compressor oil into the refrigerant cycle, please use the anti-counter-flow adapter.
