Install packet for the WR2500

The WR2500 is a through-the-wall unit. You set it in a non-loadbearing interior wall, drain condensate, land a dedicated 15A circuit, and leave published clearances. Wine-R does not certify installers.

The install is straightforward when the site is correct: no refrigerant work, no ductwork, no specialized trade beyond the dedicated circuit. Cutout 15 5/8 in by 9 1/4 in. Walls 5.5 to 14 in. A condensate drain is mandatory. Opening match is not a completed job.

On the job

Takeaways

  1. 01Read the installation reference before you bid the labor.
  2. 02Cutout 15 5/8 in by 9 1/4 in. Walls 5.5 to 14 in. Opening match is not a completed job.
  3. 03A condensate drain is mandatory. Slope it. Long or rising runs need a pump.
  4. 04Wine-R does not operate an installer network or a certification program. Pro accounts get the spec kit, job routing, and a direct technical line.
  5. 05Use the job inbox to send a city and a date. A person routes it.

Sequence that avoids a callback

  1. 01Confirm non-loadbearing interior wall, 5.5 to 14 in, before you bid.
  2. 02Cut the opening to 15 5/8 in by 9 1/4 in, typically above the door.
  3. 03Land a dedicated 115V / 60Hz / 15A outlet. No switch, no extension cord.
  4. 04Slope the condensate line. Runs over 5 ft or any rise need a pump.
  5. 05Keep 12 in cold-side and 18 in warm-side clear. Do not box the chassis.
  6. 06Commission to setpoint only after the envelope is confirmed.

Warranty voids

The calls we do not want

Drainage

No slope, a rise, a freeze, or a blocked line looks like a bad unit. Improper drainage voids coverage for water damage.

Electrical

Shared circuits, switched outlets, and extension cords void the warranty.

Envelope

An undersized room or a leaky glass wall runs the compressor continuously. Size first.

Cutout

Cutout 15 5/8 x 9 1/4 in (397 x 235 mm), typically above the door. Walls 5.5 to 14 in (140 to 355 mm).

Drain

3/8 in ID line with continuous downward slope. Runs over 5 ft, rises, or loops need a pump.

WR2500 sequence for the wall

Install packet

The WR2500 is a factory-charged through-the-wall wine cellar cooling unit. You set it in a non-loadbearing interior wall, drain condensate, land a dedicated 15A circuit, and leave published clearances.

  1. 1. Confirm interior wall, 5.5 to 14 in, before bidding.
  2. 2. Cut 15 5/8 in by 9 1/4 in, typically above the door.
  3. 3. Keep 12 in cold-side and 18 in warm-side clear. Do not box the chassis.
  4. 4. Slope the condensate line. Runs over 5 ft or any rise need a pump.
  5. 5. Dedicated 115V/60Hz/15A. No switch, no extension cord.
  6. 6. Commission after the envelope is confirmed. Place the controller out of the supply airstream.

Common questions

Role FAQ

How do I get a project price?
Apply, then request a quote. A person at info@wine-r.com replies. Wine-R does not publish trade pricing; project pricing is provided by quote.
Will you list me publicly?
No public directory is open. Wine-R does not certify installers. Referrals, if any, stay private and job-specific.
Does a Magnum-sized opening mean it drops in?
No. The WR2500 is compatible with the 15 5/8 in by 9 1/4 in above-door opening used by the KoolR Magnum. Opening compatibility is one part of the picture. Capacity, drain, and a dedicated 115V circuit still have to be confirmed. Wine-R is not affiliated with KoolR.

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.
