The wire diameter and continuous length is under the
condition that the voltage vibration is within 2%. If the
continuous length is exceed showing value, choose the
wire diameter follow relevant regulation.

CAUTION
1. Refrigerant piping system, indoor unit-indoor unit connection
signal wires and indoor unit-outdoor unit connection singal wire
are in the same system.
2. When power cord is parallel with signal wire, please put them
into separate wire distribution pipes, and leave a proper distance.
(Reference distance: It is 300mm when current capacity of
power cord is less than 10A, or 500mm when 50A).
Please use shield wire as indoor unit/outdoor unit signal wire.

6. TEST RUNNING
Operate according to "gist for test running" on the electric control box
cover.
Test running can not start until the outdoor unit has been
connected to the power for 12hr.
Test running can not start until all the valves are affirmed
open.
Never make the forced running. (Or the protector sits back,
danger will occur.)
CAUTION
7. PRECAUTIONS ON REFRIGERANT
LEAKAGE
This air conditioner(A/C) adopts inncouous and nonflammable
refrigerant. The locating room of the A/C should big engough
that any refrigerant leakage is unable to reach critical thickness.
So certain esssential action can be taken on time.

Critical thickness------the Max. thickness of Freon without any
harm to person.
Refrigerant critical thickness: 0.44[kg/m ] for R410A.

Confirm the critical thickness through follow steps, and take
necessary actions.
1. Calculate the sum of the charge volume (A[kg]) Total
Refrigerant volume of 10HP=factory refrigerant
volume + superaddition
2. Calculate the indoor cubage (B[m ]) (as the minimum
cubage.

3. Calculate the refrigerant thickness
≤ critical thickness
Counter measure against over high thickness
1. Installmechanicalventilator to reduce the refrigerant thickness
under critical level. (ventilate regularly)
2. Install leak alarm facility related to mechanical ventilator if
you can not regularly ventilate.
b. Leak alarm related to mechanical ventilator
A. Ventilation

(Leak hunting siren should be installed in
places easily keep refrigerant)
