high fan speed first, after the system operated, test following operation parameters of the system,
including indoor units and outdoor units parameters.
1.3 Installation Preparation
1.3.1 Installation tools and instruments
All the necessary tools should be available, and their models and specifications should meet the
installation and technical requirements. The instruments and meters should be tested or verified, and
their scales and accuracy should meet the requirements. The common tools for installing refrigerant
machine are listed below.

14 Horizontal rule
In addition, tools such as electric welder, cutter, A-shape ladder, electric drill, folding machine, forming
machine, nitrogen cylinder are also generally used during the installation.
1.3.2 Audit of construction drawings
Before the engineering installation, read carefully the related drawings to understand the design
intention, audit the drawings, and then work out a detailed engineering organization plan.
1. Make sure that the pipe diameters and branch pipe models meet the technical specifications.
2. Ratio of slope, drainage mode and thermal insulation of condensate water.
3. Making of air duct and air opening, and air ventilation organization.
4. Configuration specifications, model and control mode of power cables.
5. Making, total length and control mode of control cable.
The engineering construction staff should follow the construction drawing strictly during the construction.
If any change is required, such change should be approved by the design department and be
documented.
1.3.3. Construction organization plan
Construction organization plan serves as the comprehensive technical and economic documents that
guide the construction preparation and scientific construction organization. A reasonable construction
organization plan and careful implementation of it are essential to ensure smooth construction, shorten
construction period, ensure construction quality, and improve economic results.
The construction plan should be concise and focuses on key procedures, construction method, and time
coordination, space disposal of the construction around the features of the engineering, thus to ensure
smooth construction operation.
