Compatible indoor units

This is an outdoor unit. You choose its indoor heads separately - up to the maximum this condenser supports - and you can mix room sizes and styles across the zones. The models below are the heads this unit is documented to pair with.

  • Wall-mounted air handlers

    9k, 12k

    Model numbers
    • 9k: 048-TC-9K2VR-IN
    • 12k: 048-TC-12K2VR-IN

Sizing note: do not just add up the rooms. Multi-zone condensers have a maximum total connected capacity, and connecting more head capacity than the unit is rated for is a common installer mistake that hurts efficiency and comfort. Match total head capacity to the condenser's rating.

Frequently asked questions

Can I install the Della Vita Series Multi-Zone 2-Zone 18,000 BTU R-32 208/230V (048-TCQ-MODU-1D2) myself, or do I need a pro?
Della Vita Series Multi-Zone 2-Zone 18,000 BTU R-32 208/230V (048-TCQ-MODU-1D2) is built for professional installation: the line set must be flared, evacuated, and charged, which requires EPA-certified refrigerant handling. Installing it outside the manufacturer's requirements can void the warranty, so budget for a qualified HVAC installer.
Will the Della Vita Series Multi-Zone 2-Zone 18,000 BTU R-32 208/230V (048-TCQ-MODU-1D2) keep heating in a cold winter?
The AHRI/ENERGY STAR certification lists 14,000 BTU/h of heating capacity at 5F. Rated heating operation extends down to -13 F. Certified heating efficiency is 10 HSPF2. Match those numbers against your climate's design temperature - in cold regions, output at 5F matters far more than the nameplate capacity measured at 47F.
What electrical circuit does the Della Vita Series Multi-Zone 2-Zone 18,000 BTU R-32 208/230V (048-TCQ-MODU-1D2) need?
Published electrical requirements: 230 V voltage, 14 A minimum circuit ampacity, and 20 A maximum breaker or fuse sizing. Confirm the final circuit against the unit nameplate and local code with a licensed electrician.
How far can the outdoor unit be from the indoor head?
The published maximum line-set length from the outdoor unit to one indoor head is 82 ft. The combined piping limit across all heads is 131 ft. The outdoor unit's factory charge covers up to 25 ft of line; longer runs need added refrigerant. Measure the planned routing before ordering.
