38PK/FB4

FB4P Fan Coil Unit / 38PKS Condensing Unit
Electric Cooling
Puron® (R-410A) Refrigerant

4.0 and 5.0 nominal tons

FB4P direct expansion fan coil is designed for medium and high static pressure, up to 0.6 inches water (150Pa) with cooling capacity from 5.3k watt (18 Mbtuh) to 17.6k watt (60 Mbtuh). FB4P series is available in six sizes with 10 mm thick rubber cabinet insulation density of 32 kg/m^3 to minimize energy losses. FB4P series can be installed vertical or horizontal. FB4P series comes with polyester powder painted zinc coated galvanized steel casing. Super quite multi 3 speed motor for field selection & electric heaters are available option at field installation.

The 38PKS series energy efficient split condensing units incorporate innovative technology to provide reliable cooling performance. Units are pre-wired, pre-charged with Puron® R-410A refrigerant, and tested at the factory. These units can be placed on the side of a building or can be placed on a roof without roof curbs. Each unit is designed to occupy a minimal space. Piping and drain connections are readily accessible.

38PKS Features / Benefits

  • Every compact one-piece unit arrives fully assembled, charged, tested, and ready to run
  • Designed especially for high ambient environment
  • EER (Energy Efficiency Ratio) up to 12.1
  • The small footprint coupled with the horizontal airflow design means that the 38P Series units can be installed within 200 mm (8 in) of an outside wall, on a roof, balcony or deck

Wide Range of Sizes

The 38P Series is available in 6 nominal sizes from 1.5 ton to 5.0 ton to meet the needs of residential and light commercial application.

Application Versatility

The unit can be combined with a wide variety of evaporator coils and blower packages to provide quiet, dependable comfort. Unit can be installed on a roof or at ground level.

Easy access for service and maintenance

A single panel provides immediate access to the isolated compressor and control compartment, allowing a service technician access to check unit operation without losing condenser airflow. Coils can be cleaned quickly from the outside.

Secure operation

If security is an issue, outdoor and indoor units are connected only by refrigerant piping and wiring to prevent intruders from crawling through ductwork. The 38P Series units can be installed 8 in. away from outside walls, protecting coils from vandals and severe weather.

Fast installation

Carrier’s compact systems take a few hours with only wire and piping needed to be installed. The fast and easy installation ensures minimal disruption to customers in the home or workplace. This Carrier advantage is especially beneficial in retrofit situations.

External Service Valves

Service valves are brass, front seating type. The 38P Series has flare connections, sweat adapter kit is provided for 7/8” tube size. Valves are externally located so refrigerant tube connections can be made quickly and easily. Each valve has a service port for ease of checking operating refrigerant pressures.

Built-in reliability

Carrier split system outdoor units are designed to provide years of trouble-free operation. The 38P Series condensing units are the only dedicated commercial units with all safety features standard to ensure high performance and lasting reliability under the most demanding situations. High-pressure and low-pressure safety switches are standard.
