Table 6 — Evaporator Fan Motor Data
NOTES:
1. Motor shaft speed is 1750 rpm. The fan shaft diameter is 1 15 /
16
inches.
2. All indoor fan motors meet the minimum efficiency requirements as estab-
lished by the Energy Policy Act of 1992 (EPACT), effective October 24,
1997.

Step 5 — Trap Condensate Drain —
See Fig. 6-14
for drain location. Condensate drain is open to atmosphere and
must be trapped. Install a trapped drain at the drain location.
One 1-in. female pipe coupling is provided inside the unit
evaporator section for condensate drain connection. A trap at
least 4 in. deep must be used. See Fig. 19. Trap must be in-
stalled to prevent freeze-up.
Condensate pans are sloped so that water will completely
drain from the condensate pan to comply with indoor air quali-
ty guidelines. The condensate drain pans are not insulated.
Step 6 — Make Electrical Connections
POWER WIRING — Units are factory wired for the voltage
shown on the unit nameplate.
Provide a unit safety disconnect switch in the main power
supply to each unit (see Fig. 20). Select switch size and mount-
ing location in accordance with applicable local codes or Na-
tional Electrical Code (NEC). If combining the functions of
safety disconnect with maximum overcurrent protection
(MOCP) fuses (“fused disconnect”), coordinate safety switch
size with MOCP size data as marked on unit informative plate.
