Heat up the unit for 12 hours after turning on the power 

switch.  Do  not  turn  off  the  power  supply  if  the  unit  is 

designed  to  stop  within  24  hours  or  less.  (This  is  for 

heating  up  the  crankshaft  heating  box  and  avoiding 

forced starting of the compressor.)
Do not block the air inlet and outlet.
Blockage may reduce the unit efficiency or activate the 

protector to shut down the unit.
Operate  the  switch  and  button  with  an  insulation  rod 

(such as a ball pen with a cap) to avoid the contact with 

energized parts.

 

Caution

18 Commissioning

18.1 Overview

After installation, and once the field settings have been defined, 

the  installation  personnel  must  verify  the  correctness  of  the 

operations. Follow the steps below to perform the test run.
This chapter describes how the test run can be carried out once 

the installation is complete, and other relevant information.
The test run usually includes the following stages:
1. Review the "Checklist Test Run".
2. Implement the test run.
3. Conduct troubleshooting before the test run is completed with 

faults, if necessary.
4. Run the system.

18.2 Things to Note During Test Run

During  the  test  run,  the  outdoor  unit  operates  at  the 

same time as the indoor units connected to it. It is very 

dangerous to debug the indoor unit during the test run.
Do  not  insert  fingers,  sticks,  or  other  items  into  the  air 

inlet or outlet. Do not remove the fan mesh cover. If the 

fan is rotating at a high speed, it may cause bodily injury. 

 

Warning

Note that the required input power may be higher when 

this unit is run for the first time. This phenomenon is due 

to the compressor which needs to run for 50 hours before 

it can achieve a stable operating and power consumption 

state. Ensure that power has been on for 12 hours and 

the crankcase heater has been charged correctly before 

operation. This is a good way to protect the compressor. 

 

Caution

A test run can be performed if the ambient temperature is 

within the range indicated in Figure 18-1.

18.3 Test Run Checklist

Once this unit is installed, check the following items first. After all 

following checks have been completed, you must shut down the 

unit. This is the only way to start the unit again.

Table  18-1

Installation 

Check if the unit is installed correctly to prevent strange 

noises and vibrations from occurring when the unit starts.

Field wiring 

Based  on  the  wiring  diagram  and  the  relevant 

regulations,  make  sure  the  field  wiring  is  based  on 

instructions described in Section 16.2 and Section 16.3 

on connecting wires.

Grounding wire 

Make sure the grounding wire is connected correctly, and 

the grounding terminal is tight.

Insulation test of main circuit 

Use the megameter of 500 V, apply a voltage of 500 V DC 

between the power terminal and the grounding terminal. 

Check that the insulation resistance is above 2 MΩ. Do 

not use the megameter on the transmission line.

Fuses, circuit breakers, or protection devices 

Ensure that the fuses, circuit breakers, or locally installed 

protection devices comply with the size and type specified 

in "16.1 Requirements for Safety Devices". Make sure you 

use fuses and protection devices.

Internal wiring 

Visually inspect if the connections between the electrical 

component box and the interior of the unit is loose, or if 

the electrical components are damaged.

Piping dimensions and insulation 

Make sure the installation piping dimensions are correct, 

and the insulation work can be carried out normally.

Stop valve 

Make sure the stop valve is open on both the liquid and 

gas sides.

Equipment damage 

Check  for  damaged  components  and  extruded  piping 

inside the unit.

Refrigerant leak 

Check the inside of the unit for refrigerant leak. If a leak 

exists,  keep  the  area  ventilated  to  avoid  refrigerant 

accumulation and eliminate/put out any open flames. Do 

not touch the refrigerant leaked from the refrigerant piping 

connection. It may cause frostbite.

Oil leak 

Check if there is oil leaking from the compressor. If an oil 

leak occurs, please turn off the power supply and contact 

the distributor.

Air inlet/outlet 

Check  for  paper,  cardboard  or  any  other  material  that 

may obstruct the air inlet and outlet of the equipment.

Charge additional refrigerant. 

Indicate the amount of refrigerant to be charged to the 

unit in the "Confirmation Table" on the front cover of the 

electrical control box.

Installation date and field settings 

Record the installation date and field settings.
