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.

A[kg]

B[m ]

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

3. Calculate the refrigerant thickness

İ

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 
    peristome 

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