Amana PTAC Condensate Drain Kit for WS900E Wall Sleeves, DK900D
The Amana DK900D Condensate Drain Kit is the drain kit Amana specifies for its WS900E standard-depth PTAC wall sleeve. It attaches to the sleeve base pan so condensate from the PTAC can be carried away in a controlled way, either outside the building or to an interior drain. The kit is field installed and should go in before the chassis and outdoor grille. It is the right choice for contractors, maintenance teams and property managers working with WS900E sleeves in hotels, apartments, senior living, dorms and offices.
Is the DK900D the Right Drain Kit for Your Sleeve?
Choose by wall sleeve model, not by PTAC chassis. Amana's accessories catalog pairs the DK900D with the Amana WS900E PTAC wall sleeve, its 42" wide × 16-1/16" high sleeve with the industry-standard 14⅛" depth. Amana also lists the DK900D as the separately sold drain for its WS900D-INTERNAL window-wall sleeve. If you're installing a newer WS900QW sleeve, Amana specifies the DK900QW instead.
Choose the drain method before the sleeve and chassis go in. For an indoor drain, the parts mount to the sleeve bottom before the sleeve is set in the wall. For an outdoor drain, they go on the rear of the sleeve before the Amana SGK01B outdoor grille is attached. Local building codes decide which method is allowed, so check before you plan the drain line.
Ideal for: New installations and sleeve change-outs using Amana WS900E wall sleeves in hotels, motels, apartments, assisted living, dormitories, hospitals and offices.

The DK900D is a combination kit, so the same box handles internal or external drainage. Install only the parts for the method you choose. The gaskets and blank-off plates seal the sleeve's unused drain holes against water and weather. The kit connects the sleeve to your drain system but doesn't include the drain line, so plan to supply tubing or piping to carry condensate to an approved location.

Frequently Asked Questions
Which Amana wall sleeve is the DK900D made for?
Amana's accessories catalog lists the DK900D for use with the WS900E wall sleeve. It is also the separately sold drain for the WS900D-INTERNAL window-wall sleeve. For WS900QW sleeves, Amana specifies the DK900QW.
Is a condensate drain kit required on a new PTAC install?
Yes, on new installations a drain kit should be installed so condensate is controlled rather than left to overflow the sleeve. It must go in before the chassis and outdoor grille.
What's the difference between the DK900D and the DK900QW?
Both are Amana combination drain kits for internal or external drainage. The difference is the sleeve they're specified for: the DK900D pairs with the WS900E, and the DK900QW pairs with Amana's WS900QW sleeve.
Can I add the drain kit after the wall sleeve is already installed?
An external drain can be added from inside the room by removing the rear enclosure panel and sleeve stiffener, as long as the outdoor grille isn't on yet. An internal drain mounts through the sleeve bottom and is meant to go in before the sleeve is set in the wall.
What if the internal drain line won't be connected right away?
Amana recommends plugging the indoor drain fitting (a cork works) until the drain line is connected. That keeps rain driven into the sleeve from leaking into the room.
What else do I need to finish a WS900E sleeve installation?
Along with the sleeve and drain kit, you'll need an outdoor grille, such as the SGK01B stamped aluminum grille, a field-supplied drain line, and a compatible Amana PTAC chassis and thermostat.
