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

8. TURN OVER TO CUSTOMER
The owner's manual of indoor unit and owner's manual of
outdoor or unit must be turned over to the customer. Explain
the contents in the owner’s manual to the customers in details.
Please press “constraint cool” button to carry out refrigerant
recycling process. Keep the low pressure above 0.2MPa, other
wise compressor may be burnt out.

7.1 Important information for the used
refrigerant
This product has the fluorinated gas which is listed in kyoto protocol
it is forbidden to release to air.
Refrigerant type: R410A; Volume of GWP: 2088;
GWP=Global Warming Potential
Attention:
Frequency of Refrigerant Leak Checks
1) For equipment that contains fluorinated greenhouse gases in
quantities of 5 tonnes of CO
2
equivalent or more,but of less than
50 tonnes of CO
2
equipment,at least every 12 monthes, or where
a leakage detection system is installed, at least every 24 monthes.
2) For equipment that contains fluorinated greenhouse gases in
quantities of 50 tonnes of CO
2
equivalent or more,but of less than
500 tonnes of CO
2
equipment,at least every six monthes, or where
a leakage detection system is installed, at least every 12 monthes.
3) For equipment that contains fluorinated greenhouse gases in
quantities of 500 tonnes of CO
2
equivalent or more,at least every
three monthes, or where a leakage detection system is installed,
at least every six monthes.
4) Non-hermetically sealed equipment charged with fluorinated
greenhouse gases shall only be sold to the end user where evidence
is provide that the installation is to be carried out by an undertaking
certified person.
5) Only certificated person is allowed to do installation, operation
and maintenance.
