7 Are heat insulating measures for the water tank, outlet/inlet pipes and water replenishing pipe proper?
Are the nilometer of water tank, water temperature indicator, controller, manometer, pressure relief valve and
8
automatic discharge valve etc. installed and operated properly?
9 Does power supply accord with the nameplate? Do power cords conform to applicable requirements?
Is power supply and control wiring connected properly according to wiring diagram? Is earthing safe? Is each
10
terminal stable?
11 Are connection pipe, water pump, manometer, thermometer, valve etc. are installed properly?
12 Is each valve in the system open or closed according to requirements?
13 Confirm that the customers and inspection personnel of Part A are at site.
14 Is Installation Check-up Table completed and signed by the installation contractor?
NOTE: If there is any item marked with ×, please notify the contractor. Items listed above are just for reference.
General Evaluation: Debugging □
Judge the following items (if there is not any filling, qualification will be regarded.)
a: Power supply and electric control system
c: Heating problems of Unit
e: Pipeline problem
Normal debugging work can't be performed unless all installation items are qualified. If there is any problem,
it must be solved firstly. The installer will be responsible for all costs for delay of debugging and re-debugging
incurred by any problem which is not solved immediately.
Submit schedule of amending reports to installer.
Is the written amending report which should be signed after communication provided to installer?

20.2 Test run

Test run is testing whether the unit can run normally via preoperation. If the unit cannot run normally, find and
solve problems until the test run is satisfactory. All inspections must meet the requirements before performing the
test run. Test run should follow the content and steps of the table below:
The following procedure should be executed by experience and qualified maintenance men.
No.
Notice: before test, ensure that all power must be cut off, including the far- end power switch, otherwise, it may cause
casualty.
1 Ensure that the compressor of the unit is preheated for 8h.
NOTE: heat the lubricating oil at least 8h in advance to prevent refrigerant from mixing with the lubricating oil, which
may cause damage to the compressor when starting up the unit.
Check whether the oil temperature of the compressor is obviously higher than the outdoor ambient
2
temperature.
NOTE: if the oil temperature of the compressor is obviously higher than the outdoor ambient temperature, it means
that the heating tape of compressor is damaged. In that case, the compressor will be damaged easily. Therefore, repair
the heating tape before using the unit.
Check whether the phase sequence of the main power supply is correct. If not, correct the phase sequence
3
firstly.
NOTE: recheck the phase sequence before start-up to avoid reverse rotation of the compressor which may damage
the unit.
Apply the universal electric meter to measure the insulation resistance between each outdoor phase and earth
4
as well as between phases.
NOTE: defective earthing may cause electric shock.
