About The Lennox CK40CT-30/36B-01
Description
The Lennox CK40CT-30/36B-01 is a cased upflow evaporator coil for 2.5 to 3 ton R-410A systems, with a factory-installed R-410A expansion valve. It fits a 17.5-inch B cabinet Lennox furnace.
Key specs
- Capacity: 2.5 to 3 tons nominal
- Refrigerant: ships with an R-410A expansion valve and is R-454B compatible
- Cabinet: B size, 17.5 inches wide
- Connections: 3/4-inch suction and 3/8-inch liquid, sweat, plus two 3/4-inch FPT condensate drains on an anti-microbial drain pan
- Construction: Lennox Quantum coil with aluminum tubing and ripple-edged aluminum fins
Reading the model number
The first C means indoor coil, K means R-454B compatible, and 40 is the Quantum coil series. The C after 40 is the upflow cased cabinet, T is the factory expansion valve, 30/36 is the 2.5 to 3 ton size, B is the 17.5-inch cabinet that matches B furnaces, and 01 means an R-410A expansion valve is installed. You may also see it written as CK40CT-30-36B-01.
What it pairs with
It lines up with Lennox furnaces that carry the B cabinet letter. As shipped, it's set up for R-410A. The air conditioners and heat pumps we sell use R-454B, so pairing it with one needs Lennox's R-454B expansion valve and refrigerant detection parts, ordered separately.
Sizing and fit
Choose the size to match your outdoor unit's tonnage, and the cabinet letter to match your furnace. Have your outdoor unit's model number ready when you call, and we'll check it against Lennox's AHRI matchups.
Warranty and registration
HVAC USA is an authorized Lennox reseller, and everything we sell is new factory equipment. Your full Lennox warranty applies when a licensed, manufacturer-certified contractor installs your system and registers it within 60 days.
Shipping and help
It ships from our Kansas City warehouse. Call (913) 364-0070, Monday to Friday, 9am to 5pm CST, and we'll help you confirm sizing and an AHRI-matched pairing before you order.
