Office, club, or house: same WR2500 decisions

If you are not a designer, architect, operator, developer, builder, or HVAC contractor, you still use the same decisions: envelope, volume, opening, drain, circuit, and who installs.

The same decisions

Office, club, or house

  1. 01Envelope first. R-20, vapor barrier on the warm side.
  2. 02Volume and glass. Then the BTU calculator.
  3. 03Opening 15 5/8 in by 9 1/4 in, walls 5.5 to 14 in.
  4. 04Dedicated 115V / 60Hz / 15A circuit.
  5. 05Mandatory condensate drain with downward slope.
  6. 06Through-the-wall. Noise and heat stay at that wall.

Before you cut

Leased space

In a leased space, confirm with the landlord before cutting an opening. The wall must be a non-loadbearing interior wall, and the warm side needs a room that can take rejected heat.

Specification sequence

How to specify the WR2500

For cellars that have to look finished with a through-the-wall unit in the wall. The drawing set carries the envelope, the load, the opening, the drain, and the electrical. There is no remote compressor to hide in another room.

  1. 1. Confirm the envelope. R-20 walls and floor, sealed vapor barrier on the warm side. Double-pane sealed glass only. Single-pane and non-insulated glass are not permitted and void warranty coverage.
  2. 2. Size the load. Enter length, width, height, glass, and insulation in the BTU calculator. The WR2500 covers up to 700 ft³ (19.8 m³) with glass walls or 900 ft³ (25.5 m³) fully enclosed when the envelope meets specification.
  3. 3. Place the unit. A non-loadbearing interior wall, 5.5 to 14 in thick. Cutout 15 5/8 in by 9 1/4 in, typically above the door. The face is in the cellar wall.
  4. 4. Route the drain. Mandatory 3/8 in ID condensate line with continuous downward slope. Runs over 5 ft, rises, or loops need a pump.
  5. 5. Electrical. Dedicated 115V/60Hz/15A. Do not share the circuit with lighting. No extension cord. No switched outlet.
  6. 6. Installation. DIY-feasible when the site is correct. A contractor or HVAC installer can set it. Wine-R does not certify installers.

Millwork can frame the face if free area and published clearances stay open. Leave a path to remove the unit without dismantling finished cabinetry. 2-year parts warranty.

One portal. Seven roles.

Approval is a human review. No auto-approve on pricing. You are applying directly with Wine-R, not through a dealer.

Specification support notice

Wine-R Pro documents support design, bid, and specification work. They are not a site assessment, an engineering approval, or an installation certification. Final sizing, opening, drainage, and electrical are confirmed on site by the responsible trades. Wine-R does not install and does not certify installers. The WR2500 is sold under Wine-R’s Terms of Sale and Limited Warranty.

Liability and warranty considerations

The WR2500 is sold under Wine-R’s Terms of Sale and Limited Warranty. Wine-R’s warranty covers unit parts for two years from the original purchase date.

Warranty coverage is voided by, among other conditions:

  • Damage from improper installation, poor insulation, or oversized or unsealed rooms
  • Use of extension cords, switch-controlled outlets, or non-dedicated circuits
  • Use of single-pane or non-insulated glass in the cellar envelope
  • Installation through an exterior wall, into a sealed cavity, or into an unventilated cabinet
  • Service performed by anyone other than Wine-R or a Wine-R authorized technician
  • Damage from drainage installation, blockage, overflow, or any drainage failure

Pre-validation by Wine-R confirms unit fitment against declared measurements only. The owner or installer is responsible for envelope construction, wall structural assessment, electrical compliance, drainage routing, and ongoing operating conditions. Wine-R does not warrant against water damage, mold, finish degradation, or property loss caused by installation, drainage configuration, site conditions, or operating environment.
