FB4CSL/38CKM

FB4CSL Fan Coil Unit / 38CKM Condensing Unit
Electric Cooling Puron® R-410A Rerigerant

1.5 to 5.0 nominal tons

The 50 Hz FB4C fan coil has the proven technology of Carrier fan coil units with Puron refrigerant as well as vertical and horizontal applications. Downflow installations require an accessory package.The design features contoured condensate pans with rugged drain connections, ensuring that little water is left in the unit at the end of the cooling duty cycle. The lack of standing condensate and corrosion free pans improves IAQ and product life, features homeowners appreciate. Standard features include grooved tubing and louvered fins. Coil circuiting has also been updated to make the most of all Carrier heat pumps and air conditioners. Units come with solid state fan controls, 1- inch (25mm) thick insulation with R- value of 4.2, multi- speed motors, and fully-wettable coils. The FB4C fan coil design is loaded with popular features. These fan coils utilize the latest in electronic commutation motor (ECM) technology through the use of high efficiency, multi- tap ECM motors allowing reliable air delivery with increased static pressure. It comes in a pre- painted (American Sterling) galvanized steel casing and a factory- supplied power plug for ease of installation.The FB4C unit is shipped with a Puron refrigerant TXV.

Model 38CKM 50 Hertz energy efficient air conditioner incorporates innovative technology to provide reliable summer cooling performance. Built into these units are the features most desired by customers today, including EER ratings of up to 13 at the T1 condition when used with components designated by the manufacturer

38CKM Features

Available Sizes

Nominal sizes are available from 018 through 060 to meet the needs of residential and light commercial applications.

Electrical Range

Units offered in single phase 230v and 240v (sizes 018--036), three phase 400v and 415v (sizes 036--060).

Fan Motor

The totally enclosed ball bearing fan motor provides greater reliability under adverse conditions and dependable performance for many years. The permanent split capacitor type motor is designed for optimum efficiency. The motor is then qualified under extreme conditions to help ensure a long, reliable life.

Cabinet

A weather protective cabinet of prepainted steel is protected underneath by a galvanized coating and treated with a layer of zinc phosphate for a finish that will last for many years. All screws on cabinet exterior are coated for a long--lasting, rust--resistant, quality appearance.

Unit Design

Aluminum fin material is pre--coated on both sides with a corrosion protective coating, capable of 1000 hr salt spray exposure per ASTM B117 test. The copper tube, with enhanced sine wave coated aluminum fin coil, is designed for optimum heat transfer and corrosion protection. Vertical air discharge carries sound and hot condenser air up and away from adjacent patio areas and foliage. The base pan is designed for easy removal of water, dirt, and leaves.

Dense Grille

A narrow spaced coil grille is factory supplied for improved coil protection.

Compressor

Each compressor is protected with internal temperature—and current--sensitive overloads. An internal pressure relief valve provides high pressure protection to the refrigerant system. For improved serviceability, all models are equipped with a compressor terminal plug.
