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
8. 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
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

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