7-Figure Service Add-On
For professional HVAC use only

Installation Procedures

Quick field procedure for qualified HVAC technicians — measurement, installation, and verification.

Confirm System Condition Before Installation

7-Figure Service Add-On should only be installed on systems operating in accordance with manufacturer specifications, with no outstanding required repairs, and in proper working order.

Do not use 7-Figure Service Add-On to mask unresolved mechanical, electrical, refrigerant, airflow, or maintenance issues.

Before You Install

System operating correctly
No required repairs outstanding
Airflow acceptable
Thermostat operating correctly
System running at full load
AMP draw can be checked

If the system is not operating correctly, do not proceed.

Quick Installation & Verification Steps

  1. 1

    Step 1 — Force Full Load Operation

    • Cooling: set thermostat to the lowest setting
    • Heating: set thermostat to the highest setting
    • Run system for 5–10 minutes
    • Confirm full-load operation using AMP draw
  2. 2

    Step 2 — Take Pre-Install Reading

    • Use the register closest to the air handler
    • Record supply air temperature
    • Record AMP draw
    • Use the same register for the post-install reading
  3. 3

    Step 3 — Install 7-Figure Service Add-On

    • Use correct approved dosage
    • Follow approved injection method
    • Keep system running during installation
    • Maintain suction line access
  4. 4

    Step 4 — Allow Circulation

    • Allow 5–10 minutes for circulation
    • Confirm system remains at full load
    • Confirm AMP draw is similar to the pre-install reading
  5. 5

    Step 5 — Take Post-Install Reading

    • Use the same register
    • Monitor for 5–15 minutes
    • Expected improvement: 1°–4°F
    • Record supply air temperature and AMP draw
  6. 6

    Step 6 — Restore System Settings

    • Return thermostat to original setting
    • Confirm normal system operation
    • Complete customer paperwork / service notes

Important Note for Inverter Systems

Inverter systems may ramp down quickly once 7-Figure Service Add-On improves coil efficiency.

If this occurs before a post-install reading is captured, document the observation. Equal or improved delivered air temperature at reduced capacity may indicate improved coil efficiency and reduced compressor workload.
