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 force run the unit. (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 be big enough
that any refrigerant leakage is unable to reach critical thickness.
So certain esssential action can be taken in time.

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

Confirm the critical amount through the following 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 amount

critical amount
Counter measure against high amount
1. Install mechanical ventilator to keep the refrigerant amount
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

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.
