1.Fully open both shutoff valves.
2.Connect service gage manifold to the valve service
    ports, being sure to evacuate lines.
3.Startup the system (Refer to the Section 7 - "System
   Startup"). Run system at least 10 minutes to allo
    pressure to stabilize.
4.Temporarily install thermometer on suction (large)
    line near condensing unit. Be sure of good contact
    between thermometer and line. Wrap thermometer
    with insulating material to assure accurate reading.
5.Refer to 

Table 3

 for proper system superheat. Add

   charge to lower superheat. Remove charge to raise
   superheat.
   Carefully remove gage lines.

6.4.ELECTRICAL WIRING

! WARNING -

A means of strain relief must be installed to this appliance at the electrical service entrance.

Make sure that interconnecting wires between indoor and outdoor units meet the standards, codes
and regulations. Incomplete connection or fixing of the wire could result in a fire.

A means of strain relief must be installed to this appliance at the electrical service entrance.
Do not use intermediate connection of the power cord or the extension cord and do not connect
many devices to one AC outlet

. It could cause a fire or an electric shock due to defective contact,

defective insulation, exceeding the permissible current, etc.

Perform electrical work according to the installation manual and be sure to use an exclusive
circuit.

 If the capacity of the power circuit is insufficient or there is incomplete electrical work, it

could result in a fire or an electric shock.

Ground the unit.

 Do not connect the ground to a gas pipe, water pipe, lighting rod or telephone

ground. Defective grounding could cause an electric shock.

Electrical installation will consists of power supply wiring to the condensing unit and control wiring
between thermostat, indoor unit and the condensing unit.  All wiring must be in accordance with National
Electrical Code and/or local ordinances that may apply.

(See unit wiring diagram furnished with this instruction).

Note: Some states need the power supply wiring within special tybe be careful to use the waterproof
tube when installation the outdoor unit power supply wiring.(See the figure 4)
