Installation (Continued)
Condensate Drain Connection
Each commercial rooftop unit is equipped with one (1) 1-1/4
inch Female PVC condensate drain connection.
Refer to Figure 2 for the location of the connector. A conden-
sate trap must be installed due to the drain connection being
on the "negative pressure" side of the fan. Install a P-Trap at
the unit using the guidelines in Figure 5.
Pitch the drain line at least 1/2 inch for every 10 feet of hori-
zontal run to assure proper condensate flow.
Ensure that all condensate drain line installations comply
with applicable building and waste disposal codes.

O/A Sensor & Tubing Installation
An Outside Air Pressure Sensor is shipped with all units de-
signed to operate on variable air volume applications.
A duct pressure transducer and the outside air sensor is
used to control the discharge duct static pressure to within a
customer-specified controlband. Refer to the illustration in
Figure 6 and the following steps to install the sensor and the
pneumatic tubing.
1. Remove the O/A pressure sensor kit located inside the fan
section. The kit contains the following items;
- an O/A static pressure sensor
- a sensor mounting bracket
- 2' of 3/16" O.D. pneumatic tubing
- mounting hardware
2. Using two #10-32 x 1-3/4" screws provided, install the
sensor's mounting bracket to the factory provided bracket
(near the fan section).
3. Using the #10-32 x 1/2" screws provided, install the O/A
static pressure sensor vertically to the sensor bracket .
4. Remove the dust cap from the tubing connector located
below the sensor in the vertical support.
5. Attach one end of the 2' x 3/16" O.D. factory provided
pneumatic tubing to the sensor's top port, and the other
end of the tubing to the connector in the vertical support.
Discard any excess tubing.
