IDB: Entering Indoor Dry Bulb Temperature. Shaded area reflects ACCA (TVA) conditions. kW = Total system power. High and low pressures are measured at the liquid and suction access fittings. Amps: Unit amps (comp.+ evaporator + condenser fan motors).

The Expanded Cooling Data tables for other models (GPGM324***41, GPGM330***41, GPGM336***41, GPGM342***41, GPGM348***41, GPGM361***41) follow a similar structure, providing detailed performance metrics across various operating conditions. Due to the extensive nature of these tables, they are summarized here. Please refer to the original document for complete data.

Airflow Data

The Airflow Data tables provide CFM (Cubic Feet per Minute) and Watt consumption for different ESP (External Static Pressure) values across various heating and cooling speeds (T1-T5). These tables help in selecting the appropriate fan speed for desired airflow and operating conditions.

Example data for GPGM32404041:

Charts and Diagrams

Temperature Rise Range Chart

A graphical chart illustrates the relationship between BTU Output and Temperature Rise, with lines indicating different CFM (airflow) values. Formulas are provided:

BTU/h Output = CFM x 1.08 x Rise
Rise = BTU/h Output / (CFM x 1.08)

Wiring Diagrams

Detailed wiring diagrams are included for different model series (GPGM324/330/336, GPGM342/348, GPGM361). These diagrams illustrate the electrical connections for components such as the Integrated Ignition Control (IIC), compressor, motors (evaporator, condenser, inducer), gas valve, safety switches (limit, pressure, rollout), and thermostat connections.
