9 TEST RUNNING

Operate according to "key points 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 12 hours.
● 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.)

10 PRECAUTIONS ON REFRIGERANT
LEAKAGE
This heat pump adopts inncouous and nonflammable refrigerant. The
locating room of the HP should big engough that any refrigerant
leakage is unable to reach critical thickness.So certain esssential
action can be taken on time.
1) Critical thickness------the Max. thickness of Freon without any harm
to person.
2) Refrigerant critical thickness: 0.44[kg/m
● Confirm the critical thickness through follow steps, and take
necessary actions.
● Calculate the sum of the charge volume (A[kg]) Total
Refrigerant volume of 10HP=factory refrigerant volume +
superaddition.
● Calculate the indoor cubage (B[m
● Calculate the refrigerant thickness.Counter measure against
over high thickness
A[kg]
B[m
3) Install mechanical ventilator to reduce the refrigerant thickness
under critical level. (ventilate regularly).
4) Install leak alarm facility related to mechanical ventilator if you can
not regularly ventilate.
