2. Pull interconnecting wires up from back of indoor unit and position in close to theterminal block on indoor unit.

NOTE
Record wire colors and terminal references for uses with Outdoor Unit wire connections. Connect wiring to indoor unit per system wiring diagram.

NOTE
The indoor unit is powered from the outdoor unit, depending on local code a disconnect switch may need to be installed to a power supply circuit. Replace field wiring cover and close front cover of indoor unit.

Indoor Disconnect Switch If required

Local codes may require a disconnect switch within sight of the indoor unit. Use a DFS.Disconnect Switch Accessory Kit (Part No: DFS-SWITCH-A) to break wires going to the N(1), 2, 3, terminals on the indoor unit, as shown in the wiring diagram below

TESTING AND INSPECTION

Leaking Test

1. Connect regulated nitrogen to manifold. Attach hose to service port.
2. Open manifold valve to add nitrogen to a pressure of 500 lbs.
3. Maintain applied pressure for 30 minutes, leak-test flare fittings with soap bubbles.
4. If no leak is detected, release nitrogen.

CAUTION
Use vacuum pump, rather than refrigerant, to discharge air when installing the unit.

Vacuum Procedure

Important
Use a quality Micron Gauge to measure and validate the system vacuum achieved. Do not rely on the scale of a“bourbon tube”type gauge set to validate the depth and quality of the vacuum.

1. Remove the caps of the liquid valve, gas valve and service port.
2. Connect gauge manifold and micron gauge to the service ports provided at the liquid and suction service valves.
3. Connect a vacuum pump to the manifold gauge.
4. Open the lower pressure side of the manifold valve assembly and start the vacuum pump.
5. The switch at the high pressure side of the manifold valve assembly should be kept closed, or evacuation does not fail.
6. Operate vacuum pump until a vacuum of 500 microns or less is achieved.
7. The evacuation duration depends on the vacuum pump size and unit’s capacity, generally 20 minutes for the 9,000 BtuH units, to 1 hour for a larger 36,000 BtuH unit.
8. Close the manifold valves and shut off the pump.
9. If vacuum holds below 700 microns for 15 minutes, the system can be considered dry and leak free. Go to step 5.
10. If vacuum increases to 800 microns or greater, this is an indication of moisture in system or a leak exist. Identify leak and repair as necessary, after which repeat steps 4 and 5.
11. If moisture is suspect, purge system use triple evacuation method using dry nitrogen.

Confirm that manifold valves are closed and disconnect the vacuum pump. Open the service valves to the fully ‘back-seat’ position to let the refrigerant flow to the indoor unit and balance the pressure in system.

Important
Do not allow air to enter the connection pipe when removing the hose. Replace service valve caps and tighten.

Pipe Testing

Additional Charge

The outdoor unit contains enough refrigerant charge for up to 25 feet from the factory. When the piping is greater than 25 feet, additional charging is necessary. For the additional amount, see the table below.

Oil Return Bend

When the outdoor unit is more than 30 feet above the indoor unit, an oil return bend must be added for every 20 feet of connection pipe.

Condensate Drain Pipe Testing

Carefully and slowly add 8-10 ounces of water to the indoor unit drain pan.

• Verify the water drains easily out the condensate drain hose.
• If water does not drain easily from the drain hose, then remove kinks, increase drain pitch, or add an auxiliary condensate drain pump.
