Condensate Drain - Nordyne R-410A User Manual And Installation Instructions

CONNECTING THE RETURN AND SUPPLY
AIR FLEXIBLE DUCTS
a. The supply duct for all units is 12" in diam-
eter. The return duct is 14" diameter for all
air conditioning units.
b. The fl exible ducts can be connected to the
corresponding fi ttings with the clamps pro-
vided with the ducts. Note: All connections
should be leak tight or a loss in cooling
capacity will result.
c. The fl exible ducts may be cut to the required
length, see instructions packed with duct.
Keep all ducts as short and straight as pos-
sible. Avoid sharp bends.
d. Ducts may be spliced with sheet metal
sleeves and clamps. (See Ducting Instal-
lation Accessories page 6.)
e. Once the inner duct is connected to the
proper fi tting, the insulation and plastic
sleeve should be pulled over the connection
and clamped.
f. For homes with multiple supply ducts or for
special applications, a Y fi tting is available
to divide the supply air so it can be ducted
to different areas of the home for more ef-
fi cient cooling. Note: The Y fi tting should be
insulated for maximum performance.
Blower Speed — For optimum system
performance and comfort, it may be necessary
to change the factory set speed. See fi gure 7 for
factory settings. To change the blower speed:
High Effi ciency Motor:
1. Disconnect all electrical power to the unit
and remove the blower panel.

2. Locate the orange, red and black wires ter-
minated to the blower motor. The orange
wire controls cooling operation, red wire
controls heating operation, black controls
high speed cooling.
3. Verify the required speed from the airfl ow
data found in fi gure 7. Place appropriate
wire on the appropriate motor speed tap for
the required airfl ow point.
Check all factory wiring per the unit wiring
diagram and inspect the factory wiring connec-
tions to be sure none loosened during shipping
or installation.
CAUTION:
To avoid personal injury or property
damage, make certain that the motor
leads cannot come into contact with
any uninsulated metal components
of the unit.

CONDENSATE DRAIN

A 3/4" condensate fi tting extends out of the side
of the unit. The drain trap, shipped in the electrical
compartment, must be installed to prevent water
from collecting inside the unit. Thread the elbow
provided with the unit into the drain connection
until hand tight. Install the trap into the fi tting and
seal the joint. Make sure it is level. Route the
condensate from the trap to a suitable drain. Any
connecting tubing or hose must have the outlet
below the trap level for proper drainage.
WARNING:
Turn off electrical power before servic-
ing controls. Severe electrical shock
may result unless power is turned off.
Unit must be installed in compliance
with the National Electrical Code (NEC)
and local codes.
