8) Do not climb on a machine. Use a platform, or staging to work at higher levels.Use mechanical
lifting equipment (crane, hoist, winch, etc.) to lift or move heavy components. For lighter
components, use lifting equipment when there is a risk of slipping or losing your balance.Use only
original replacement parts for any repair or component replacement. Consult the list of
replacement parts that corresponds to the specification of the original equipment.
2.1 Common Items and Tools for Unit Commissioning and Service
In order to realize immediate and effective commissioning, maintenance and service, the following tools
and items shall be available depending on units.
I. Common tools and applications:
1) External hex wrench, incl. adjustable and non-adjustable wrenches.
2) Internal hex wrench, comp. better
3) Pressure gauge, incl. gas/liquid gauge and connective gauge pipe, mainly for measuring
pressures of various locations in the system, monitoring the pressure during adding of
refrigerant, and functioning as a switch.
4) Refrigerant recycling machine, recycling refrigerant in the system.
5) Welding torch and relative equipment, welding torch, electrode (both common electrode and
high silver electrode), and scaling powder. For copper pipe with diameter above 9.52mm, larger
welding torch is required to facilitate even heating of the copper pipe.
6) As for vacuum pump and connection gauge pipe, if the vacuum pump connection is not
common for the general gauge pipe, the connection transition pipe must be prepared.
7) As for the refrigerant tank and connection, the refrigerant tank connection must be sound and
not damaged. In addition, it is important that the connection is common for related connection
gauge pipe.
8) Scissors, generally used for connecting gasket of relative connective parts of cutting unit.
9) Brush, used for cleaning dry filter and oil filter, etc.
10) Cutter, used for cutting copper pipe. Cutters with appropriate sizes shall be prepared for cutting
copper pipes of different sizes.
11) Pliers, auxiliary tool.
12) Mouth expander, consisting of bell mouth and mouth expansion.
13) Screwdriver, incl. slotted screwdriver and Phillips screwdriver, with complete sizes.
14) Leak detector (Leak detection powder is alternative if leak detector is not convenient for
carrying.)
15) Universal meter, for measuring current and voltage of the unit (incl. compressor, fan and other
parts), as well as coil resistances of compressor, fan and electronic expansion valve, line
connection and disconnection, etc.
16) Temperature detector, for measuring temperatures of various points in the system of the unit.
17) Pipe bender, for bending the copper pipe to certain degree, and frequently used for tubing of
pipeline in the unit.
