‘Operating charge is listed on unit namepiate
tRequired fieid-suppiied fiiter areas are based on the larger of the ARI-rated (Air Conditioning & Refrigeration institute) cooling airflow or the heating airflow at a velocity of 300 ft/min
for disposable type or 450 ft/min for high-capacity type. Air filter pressure drop must not exceed 0 08 in wg
Step 5 — Connect Condensate Drain
NOTE: When installing condensate drain connection be sure
to comply with local codes and restrictions.
The unit disposes of condensate water through a y4-in.
NPT drain fitting. See Fig. 2 and 3 for location.
Install a 2-in. trap at the drain fitting to ensure proper
drainage. See Fig. 5. Make sure the outlet of the trap is at
least one-in. lower than the unit drain pan connection to
prevent the pan from overflowing. Prime the trap with
water.
If the installation requires draining the condensate water
away from the unit, connect a drain tube using a minimum
of Vs-in. OD copper tubing, y4-in. galvanized pipe or y4-in.
plastic pipe. Do not undersize the tube. Pitch the drain tube
downward at a slope of at least one inch in every 10 ft of
horizontal run. Be sure to check the drain tube for leaks.
