Spacepak Split Heat Pump System Air Handler

Overview

The SPACEPAK ESP4860JH4M is a 5-ton high velocity heat pump fan coil unit designed for residential and light commercial forced-air systems. It operates on a single-phase, 230-volt power supply and uses an electronically commutated motor (ECM) blower for efficient, variable-speed air delivery. The unit ships in a standard 230V configuration with an optional field conversion to 115V. Built-in features include an integrated control board, anti-frost control, a condensate float switch, and a condensate trap. Licensed HVAC technicians install this unit as the indoor air handler in a split heat pump system. The ESP4860JH4M is rated for 4 to 5 tons and is suited for high velocity ducted systems where compact cabinet dimensions and slide-out blower access are priorities. Its field-adjustable motor staging allows airflow tuning without additional components. The unit accepts a 3/8-inch liquid line connection and a 7/8-inch suction fitting, making it compatible with standard split-system refrigerant line sets. It is appropriate for new construction and replacement installations in residential applications.
