The primary condensate drain line must be trapped to ensure proper drainage. Electrical Requirements: High Voltage: Connections are made inside the cabinet. The Rheem RHQA-1220T is an indoor air handler

Low Voltage: Connections are located on the outside of the cabinet.

Protective devices should be "HACR" type circuit breakers or fuses.  Maintenance Checklist 

Filter Replacement: Never operate the system without a filter. Dust buildup on heating elements can cause "charring" and soil interior surfaces.

Coil Cleaning: Inspect aluminum fins and tubing for debris or blockage to maintain low air-side pressure drop. Maintenance recommendations

Drain Line: Periodically check the condensate drain for clogs or algae growth to prevent overflow.  Model Decoding (RHQA-1220T)  Code  RHQA Air Handler Series (Heat Pump/Fan Coil) 12 Cabinet Size (Standard for ~1200 CFM/3-ton units) 20 Kilowatt (kW) Heater Size (~19.2 kW) T Circuit Breaker Configuration Rheem RHQA Series Air Handler Manual - Heat Pump - Scribd
