INDOOR UNIT INSTA ATION
Installation of Mounting Bracket
1. Attach the mounting bracket to the indoor unit.
2. Find the horizontal center of the indoor unit.
3. Mark the center of the indoor unit on mounting bracket for future reference.
NOTE: The center of the mounting bracket is not the center of the indoor unit.
4. Remove the mounting brackets from the indoor unit and position the mounting bracket
on the wall in desired location. Use centering mark on mounting bracket
for centering the indoor unit on the wall.
5. Mounting bracket must be installed horizontally and level right to left.
NOTE: Condensate drain pan has built-in pitch for proper drainage.
6. Secure mounting bracket to wall with a minimum of five screws, evenly spaced to
properly support indoor unit weight.
NOTE: t is recommended to install screw anchors for sheet rock, concrete block,
brick and such type of walls.

How to Relocate Drain Hose from eft to Right Side (if required)
1. Locate drain plug on right side of the drain tray.
Firmly grab it and remove from drain tray.
2. Locate drain tube on the left side of drain tray.
Twist drain tube counter-clockwise and gently
pull to remove from the drain tray.
3. Position drain tube on the right side over the drain fitting.
Push drain tube onto fitting and rotate clockwise to lock. Verify drain tube is secure to prevent leaks.
4. nsert drain plug into left side of drain tray fitting. Verify plug is fully seated to prevent leaks.

Indoor Drain Piping
The Stealth indoor wall unit uses a gravity drain system. There is no
internal condensate pump. The drain hose must slope downward with
no kinks, raises or fluctuations.

Rubber Plug
Right Left
1. Connect the field supplied drain hose to the outlet
pipe of indoor wall unit. A field supplied transition or
adapter may be required.
2. Apply pipe insulation to the entire drain line and joints
to prevent sweating.
3. The through-wall hole for the drain hose must be lower than
the indoor wall unit drain outlet for a functional gravity drain system.
4. nstall field supplied drain hose with a downward slope from the ndoor wall unit
drain outlet to the drain hose outlet.
5. Route the condensate drain hose in the safety location to
dispose of the condensate water.
The drain hose
cannot raise upward.
The drain hose
slopes downward.

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. The switch at the high pressure side of the manifold valve assembly should be
kept closed, or evacuation does not fail.
5. Operate vacuum pump until a vacuum of 500 microns or less is achieved. 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.
6. Close the manifold valves and shut off the pump.
a. f vacuum holds below 700 microns for 15
minutes, the system can be considered dry
and leak free. Go to step 5.
b. f vacuum increases to 800 microns or greater,
this is an indication of moisture in system
or a leak exist. dentify leak and repair as
necessary, after which repeat steps 4 and 5.
f moisture is suspect, purge system use triple
evacuation method using dry nitrogen.
TESTING AND INSPECTION
eaking 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. If no leak
is detected, release nitrogen.
CAUTION
Use vacuum pump, rather than refrigerant, to discharge air when installing the unit.
