Built for Precision
Everything you need to diagnose with confidence and accuracy.
Belt-Drive Blower Setup
Properly align sheaves, tension belts, and measure amperage to prevent motor overheating.
3-Phase Power Validation
Verify phase balance, detect single-phasing, and ensure contactor integrity under load.
The Three-Step Workflow
01
Select Configuration
Specify tonnage, voltage, and heating type (gas/electric) for relevant checklists.
02
Follow Commercial Workflow
Prioritized checks for safety circuits, freeze stats, and building automation inputs.
03
Verify System Performance
Confirm supply air temperature, static pressure, and economizer operation.
Frequently Asked Questions
The economizer stays open when it's hot outside. How do I fix it?
This usually means a failed enthalpy sensor or a stuck actuator. We guide you through testing the sensor resistance and manual positioning.
I hear a squealing noise on startup. Is it the belt?
Likely. It could be a loose belt or a sheave alignment issue. Our guide helps you measure deflection and check for pulley wear.
The unit trips on high pressure but the condenser is clean. Why?
Check for non-condensables, condenser fan rotation (especially on 3-phase), or a restriction. We help isolate the cause systematically.
