1. Document Overview

The guide lists compatible indoor/outdoor models across ARTG, ARTA, ARTC, ARXB, ARXA, and ARXC series, specifying:

  • Static pressure modes

  • Recommended static pressure range (Pa)

  • Supply and return air connection dimensions

  • Optional duct connection kits (UTD-RF204, UTD-SF045T)

This document serves as a field installation and commissioning reference to ensure correct airflow matching and physical duct sizing between indoor and outdoor units

ARTG60LDTAAOTG60LBTA2060–2501162 × 2771295 × 316

Notes (Field Application):

  • Designed for high static commercial duct applications.

  • Factory-configured static range allows for multiple branch duct layouts or higher filtration resistance.

  • Use UTD-RF204 and UTD-SF045T for optimal transition and balance during airflow measurement

ARTC90LATUAOTA90LALT50–2501200 × 3501251 × 470

Application Notes:

  • Used in large commercial multi-room ducted systems.

  • Three-phase units with high static capability (up to 250 Pa) for long duct runs.

  • Supports external control features (Low Noise / Peak Cut / Error Output) as detailed in separate service documents.

Notes:

  • Slimline chassis for restricted ceiling cavities.

  • Medium static pressure range ideal for short duct runs.

3. Inverter Multi – ARTG Bulkhead Ducted Units

Purpose:
Low static, compact bulkhead systems for concealed bedroom or apartment applications.

Field Tip:
Ensure condensate drain and airflow direction match ceiling cavity layout — these units are often factory left-hand drain convertible to right-hand.

4. VRF and Commercial System Compatibility (Page 2)

For VRF and multi-indoor systems:

  • VRF Bulkhead (ARXB) models support 0–50 Pa.

  • VRF High Static (ARXC) models support 100–300 Pa.

  • VRF Slimline (ARXA) models support 30–150 Pa with identical duct connection kits (UTD-RF204 / UTD-SF045T)

5. Service Application Notes

  • Static Pressure Tuning:
    Adjustable fan speed modes allow field calibration using a manometer to achieve recommended static within table range.

  • Transition Ducts:
    Always use UTD-RF204 (return) and UTD-SF045T (supply) when adapting to non-standard ductwork to prevent turbulence and maintain rated capacity.

  • Replacement Check:
    For system retrofits, confirm compatibility of physical duct sizes and electrical phase (single/three-phase) before unit replacement.

  • Commissioning:
    Measure ESP (External Static Pressure) at both supply and return to confirm operation within recommended range for optimal airflow and noise performance.
