CondensateDrain
Installation Instructions
The unit is provided with 3/4" National Pipe Thread (NPT) con-
densate drains. (Figure 1). Any drain can be used as a primary or
secondary drain. Condensate drain lines should be installed in a
manner that does not obstruct access to the filter.
There is a secondary drain fitting supplied with the unit that will
convert any of the primary condensate drain connections into a
secondary drain connection. This fitting should be installed in any
of the primary drain connections to convert itto asecondary drain.
1. Connect the drain lines to the appropriate drain fittings. 3/4"
PVC or other type of drain line may be used. The drain line
must not be smaller than the drain fitting.
2. Install a trap in the drain line below the bottom of the drain
pan and pitch the drain lines down from the coil at least I/4"
per foot of run. Horizontal runs over 15 feet long must also
have an anti-siphon air vent (stand pipe), installed ahead
of the horizontal run. An extremely long horizontal run may
require an oversized drain line to eliminate air trapping.
3. Route to the outside or to a floor drain, laundry tray or waste
line (sewer). Check local codes before connecting to a
sewer line.
4. Insulate drain lines where sweating could cause water
damage.
5. If a gravity drain cannot be used, install a condensate
pump. Install the pump as close to the indoor section as
possible.
SpecialNoteFor DownflowInstallations
For downflow installations, a secondary overflow drain
connection must be installed to prevent water from dripping onto
live electrical components. Use the secondary fitting on the
evaporator coil.
Waste Line Connection
Ifthe condensate line is to be connected to a waste line, an open
trap must be installed ahead of the waste line to prevent escape of
sewer gases. NEVER CONNECT THE DRAIN LINE DIRECTLY
TO A WASTE LINE. ALWAYS INCLUDE AN AIR GAP AND
TRAP, (Figure 6). Be sure to keep the trap filled with water during
the winter or off season.

Air Flow Check
For proper system operation, the air flow through the indoor coil
should be between 350 and 450 cfm per ton of cooling capacity.
The air flow through the unit can be determined by measuring the
external static pressure to the unit and selecting the motor speed
tap that will most closely provide the required air flow.
1. Set up to measure external static pressure at the supply
and return duct connections (Figure 11).
2. Drill holes in the ducts for pressure taps, pitot tubes, or oth-
er accurate pressure sensing devices.
3. Connect these taps to a level inclined manometer or draft
gauge.
4. Ensure the coil and filter are clean, and all the registers are
open.
5. Determine the external static pressure with the blower op-
erating.
6. Refer to the Air Flow Data (Figure 6) table to find the speed
tap that will most closely provide the required air flow for the
system.
7. Refer to Changing the Motor Speed in these instructions if
the speed tap is to be changed.
8. Recheck the external static pressure with the new speed
tap, and confirm speed tap selection.

Maintenance
Filters
Filters must be cleaned when they become dirty. Inspect at least
once per month. The frequency of cleaning depends upon the
hours of operation and the local atmospheric conditions. Clean fil-
ters keep unit efficiency high.
Lubrication
The bearings of the blower motor are permanently lubricated.
CondensateDrains
During the cooling season check the condensate drain lines to be
sure that condensate is flowing from the primary drain but not
from the secondary drain. If condensate ever flows from the sec-
ondary drain the unit should be promptly shut off and the conden-
sate pan and drains cleaned to insure afree flowing primary drain.

LimitOperation
The temperature limit responds to over-temperature conditions in the air duct. Ifthe temperature limit trips, the electric heater relays will
be de-energized and the fan relay will be energized. Once the limit resets, the control will resume normal operation. If the limit trips four
times during a single call for heat, the control will go into a 1 hour soft lockout. During the soft lockout, the fan relay will respond to
thermostat inputs but the heater relays are disabled. Ifthe control detects a limit trip during the soft lockout, the control will go into a hard
lockout. Once in ahard lockout, the fan relay is locked on and the heater relays are disabled. Turning the power to the unit off and then on
will clear this state.
