Wiring Chart - Sinclair SDV5 C1A Series Installation Manual

Air Purging
Use a vacuum pump, to vacuum from the gas side refrigerant
adding mouth of the outdoor unit.
Don't use the refrigerant of the outdoor unit to do the vacuum.
(A certain volume of refrigerant had been added into the
outdoor unit in factory.)
Open/Close the valves
Open/Close the spools or the valves of outdoor unit with a
f5mm hexagon spanner.
Leakage Test
Test if there is any leakage on the connections of the piping
with soap water.
Heat Insulation
Heat insulation for the gas and liquid pipe separately.
Heat insulation should be fully and carefully done, because the
liquid side pipe and gas side pipe are easy to condense water
due to low temperature when cooling.
Heat proof above 120°C material should be used at the gas
side pipe.
The indoor unit connection parts should be no-gap
heat-insulated with the attached heat insulation materials.

9. WIRING CHART

Attaching wiring
The air conditioner should use separate power supply with
rated voltage.
The external power supply to the air conditioner should have
ground wiring, which is linked to the ground wiring of the indoor
and outdoor unit.
The wiring work should be done by qualified persons according
to circuit drawing.
an all-pole disconnection device which has at least 3mm
s e p a r a t i o n d i s t a n c e i n a l l p o l e a n d a r e s i d u a l c u r r e n t
device(RCD)with the rating of above 10mA shall be incorporated
in the fixed wiring according to the national rule.
Be sure to locate the power wiring and the signal wring well to
avoid cross-disturbance and their contact with connecting pipe
or stop value body.
The wiring attached to this air conditioner is 10m long. Be sure
to prolong it with wiring of the same type and proper length
if necessary. Generally, do not twist two wiring together unless
the joint is soldered well and covered with insulator tape.
Do not turn on the power until you have checked carefully after
wiring.
