Pipeline
wrapping and
wall-hole
blocking
Wrap the connection pipe and machine-connection wires together, water pipe
shall be placed under the connection pipe and shall not be wounded and
intersected, and it shall be wrapped from outdoor unit to indoor unit in case
rainwater entered and had bad influence on temperature and insulation.
Heat insulation measures shall be adopted separately for the pipeline joint of the
indoor unit.
When the pipeline was wrapped, it shall be fixed on the wall by pipe clamps for
every 1m distance.
Block the wall-hole with plaster or putty with the machine, in case the rainwater
and the wind entered. Meanwhile, make the blockage match the wall as possible.
Inspection
before
machine
testing
Check if the internal wires of the unit are connected. It needs to be noted
particularly that the wires shall be connected correspondingly; the grounding
shall be reliable; and all the naked wires shall be pressed tightly. When the
power was off, the insulating electric-resistance of the null line, the live wire and
the ground wire of the plug shall be more than 2 megohm.
Inspect whether the indoor and outdoor units are installed firmly.
Make sure that all people or objectives are away from the machine, do check it’s
safe before turn the power on.
Before installation and safety inspection, electrification is strictly forbidden.
Power connection shall be in accordance to the region or country’s safety
requirments, and make sure that wires were firmly connected.
Inspection for
machine test
When the power is on, turn on the machine by remote controller, and press every
buttom to see if the machine responds. If the machine is a floor standing one,
testing it with control panel is required.
Inspect noise and vibration of the machine, if there are any abnormal
phenomena, they shall be debugged or maintained.
Inspect the drainage of the indoor unit. Pour a cup of water on the indoor unit
evaporator and check the draining situation.
Use remote controller (control panel when floor standing machine) to adjust the
indoor fan to carry out switching of high, medium and low air speed, inspect
whether the air swinging is flexible.
Record the data of working voltage, current, system pressure, temperature,
differences of inlet and outlet air etc. under modes of cooling and heating. In
case of abnormal conditions such as smell, scorched flavor, smoking and so on,
do stop the machine for inspection and solving it immediately. If problems
caused by anything from the user, advices shall be given to improve.
