6. TEST RUNNING

Operate according to "gist for test running" on the electric control box
cover.
CAUTION
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.)
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
A[kg]
≤ critical thickness

B[m ]
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.

NOTE
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.

Attention:
Frequency of Refrigerant Leak Checks
1) For equipment that contains fluorinated greenhouse gases in
quantities of 5 tonnes of CO
50 tonnes of CO equipment,at least every 12 months, or where
2
a leakage detection system is installed, at least every 24 months.
2) For equipment that contains fluorinated greenhouse gases in
quantities of 50 tonnes of CO
500 tonnes of CO equipment,at least every six months, or where
2
a leakage detection system is installed, at least every 12 months.
3) For equipment that contains fluorinated greenhouse gases in
quantities of 500 tonnes of CO
three months, or where a leakage detection system is installed,
at least every six months.
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.
