1. Power supply
Air conditioner must use an exclusive line (over 30A)
When installation air conditioner in a wet place, try to use a circuit breaker against Current leakage.
For installation in other places, use circuit breaker as far as possible.
The parameter of power cord is over 2.5mm .

3.Calculation of refrigerant density
Calculation will be made according to the following methods:
1) Total refrigerant content of each system (kg) =content of 1 outdoor refilled refrigerant
Content of 1 outdoor system:Factory filled refrigerant
Refilled refrigerant:Filled content during installation according to the diameter and length of the
liquid piping.
2) Calculation of the minimum room sapce (m3).
3) Calculation of refrigerant density
Total refrigerant content
Minimum room space
Refrigerant density:0.3(kg/m3)
Installation inspection and test run:
Please operate unit according to this Manual.
Items to be checked during test run. Please made a " "in " "
Are there any gas leakage?
How is insulation at piping connection carried out?
Are electric wires of indoor and outdoor unit firmly inserted into terminal block?
Is electric wiring of indoor and outdoor securely fixed?
Is draminage securely carried out?
Is earth line ( grounding ) securely connected?
Is power supply voltage abided by the code?
Is there any noise?
Is control display normal?
Is cooling operation normal?
Is room temp. regulator normal?

2. Pipe cutting and flaring
Be sure to carry out deburring after pipe cutting with a pipe cutter.
Insert flaring tool to make a flare.
Correct
Lean Damaged flare Crack
Partial Too outside
Incorrect
Such means for disconnection must be incorporation in the fixed wiring
The breaker of the air conditioner should be all-pole switch ; and the distance between
no less 3 mm.
its two contacts should be
