Compressor Protection Module
An electronic protection module is provided with com-
pressors utilized in model size 150. This module will
protect against phase reversal and phase loss at start-up.
Protection is active for 5 seconds after the first second
of compressor operation. In the event that either phase
sequencing or phase loss has occurred the following
blink sequence will display on the module.

Notes to Performance Data Tables
The following notes apply to all performance data tables:
• Three flow rates are shown for each unit. The lowest flow rate shown is used for geothermal open loop/well water systems
with a minimum of 10°C EST. The middle flow rate shown is the minimum geothermal closed loop flow rate. The highest
flow rate shown is optimum for geothermal closed loop systems and the suggested flow rate for boiler/tower applications.
• Water temperatures below 4.4°C assumes 15% antifreeze solution.
• Interpolation between ELT, EST, and GPM data is permissible.
• Operation in the gray areas is not recommended.
