{
Required filter sizes shown are based on the larger of the AHRI (Air Conditioning Heating and Refrigeration Institute) rated cooling airflow or the heating air-
flow velocity of 300 to 350 ft/minute for throwaway type. Air filter pressure drop for non---standard filters must not exceed 0.08 IN. W.C.

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--6 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. 9). 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
downward at a slope of at least 1--in. (25 mm) for every 10 ft (3.1
m) of horizontal run. Be sure to check the drain tube for leaks.
