Step 6 — Connect Condensate Drain
NOTE: When installing condensate drain connection be sure to
comply with local codes and restrictions.
This unit disposes of condensate water through a 3/4 in. NPT
fitting which exits through the base on the evaporator coil access
side. See Fig. 3 & 4 for location.
Condensate water can be drained directly onto the roof in rooftop
installations (where permitted) or onto a gravel apron in ground
level installations. Install a field- -supplied 2- -in. (51 mm)
condensate trap at the end of condensate connection to ensure
proper drainage. Make sure that the outlet of the trap is at least 1 in.
(25 mm) lower than the drain- -pan condensate connection to
prevent the pan from overflowing (See Fig. 7). Prime the trap with
water. When using a gravel apron, make sure it slopes away from
the unit.
Connect a drain tube using a minimum of 3/4- -in. PVC or 3/4- -in.
copper pipe (all field- -supplied) at the outlet end of the 2- -in. (51
mm) trap. Do not undersize the tube. Pitch the drain tube
