Wiring - Westinghouse 9K/12K Use And Installation Instructions

Installation instructions
· Additional r efrigerant c harge
The unit has been filled with refrigerant.
Please calculate additional charge according to "Piping Requirement" .
After finishing vacuum pump procedures, first exhaust air from charge hose, then open valves, charge refrigerant
as "liquid" type through liquid stop valve.
At the end, please close valves and record the refrigerant charge quantity.

Wiring

·Turn OFF the main power switch of the indoor unit and the outdoor unit and wait for more than 3 minutes before
electrical wiring work or a periodical check is performed
·Check to ensure that the indoor fan and the outdoor fan ha ve stopped before electrical wiring work or a periodical
check is performed.
·Protect the wires electrical parts etc from rats or other small animals If not protected rats may gnaw at
,
unprotected parts and at the worst a fire will occur
·Avoid the wiring from touching the refrigerant pipes plate edges and electrical parts inside the unit
If so, the wires will be damaged and at the worst a fire will occur
·Install an ELB (Electric Leakage Breaker) in the power source .
If ELB is not used it will cause electric shock or fire at the worst ,
·This unit uses an inverter which means that it must be used with an earth leak detector capable of handling
harmonics in order to prevent malfunctioning of the earth leak detector itself.
·Do not use intermediate connection wires, stranded wires(see "Attentions when Connecting the Power Supply
Wiring", extension cables or control line connection, because the use of these wires may cause heating, electric
shock or fire.
·The tightening torque of each screw is shown as follows
M4 0.7 to 1 0 lbf ft (1 0 to 1 3 N m) : . · .
M5 1.5 to 1.8 lbf ft (2 0 to 2 5 N m) : · .
M6 3.0 to 3.7 lbf ft (4 0 to 5 0 N m) : · .
M8 6.6 to 8.1 lbf ft (9 0 to 11 0 N m) : · .
M10 13.3 to 17.0 lbf ft (18 0 to 23 0 N m) :
Keep the above tightening torque during wiring work .
·With tape material along the wire wrapped, sealed wiring holes, prevent the condensed water leaks and insects.
·Tightly secure the power source wiring using the cord clamp inside the unit.
Note: Fix the rubber bushings with adhesive when conduit tubes to the outdoor unit are not used.
General Check
(1) Make sure that the field-selected electrical components (main power switches, circuit breakers, wires, conduit
connectors and wire terminals) have been properly selected according to the electrical data.
Make sure that the components comply with National Electrical Code (NEC).
(2) Check to ensure that the voltage of power supply is within ± 10% of nominal voltage and earth phase is contained
in the power supply wires. If not, electrical parts will be damaged.
(3) Check to ensure that the capacity of power supply is enough.
If not, the compressor will not be able to operate because of abnormal voltage drop at starting.
(4) Check to ensure that the earth wire is connected.
(5) Install a main switch, multi-pole main switch with a space of 1/8 in. (3.5mm) or more, single phase main switch
with a space of 1/8 in. (3.0mm) or more between each phases.
(6) Check to ensure that the electrical resistance is more than 2MΩ, by measuring the resistance between ground
and the terminal of the electrical parts. If not, do not operate the system until the electrical leakage is found and
repaired.
Filling a cylinder with an attached siphon
Stand the cylinder upright when filling.
Stand the cylinder upright when filling.
There is a siphon pipe inside,so the cyliner
need not to be upside-down to fill with liquid.
