This document is an installation manual for the Unico V2430/3036/3642 Vertical Air Handler Unit (V-AHU), which is a single-packaged indoor comfort system. It includes both cooling and heating coils within the same cabinet and is designed for vertical up-flow configuration. The unit is available in three sizes: 2430, 3036, and 3642, with nominal maximum capacities of 24,000, 30,000, and 36,000 Btu per hour, respectively. The system uses small-diameter ducts (two-inch diameter) to deliver conditioned air, which then entrains and mixes with room air, providing even temperature distribution through aspiration.
The Unico V-AHU provides indoor comfort through heating and cooling. It can be configured as heating-only (blower/motor and hot water coil), cooling-only (blower/motor and cooling coil), or a combined heating and cooling system (both coils, with the cooling coil being a heat pump coil, B-Style or E-Style). The unit features an EC motor and SCB control as standard, offering variable-speed operation. It is designed to operate with a low-velocity return air system, ensuring quiet operation. The system includes a pleated filter for air filtration, which can be easily removed and replaced.
The Unico System is certified to UL Standard 1995 and conforms to CAN/CSA Standard C22.2 NO. 236, and Unico products comply with European regulations for product safety, as indicated by the ETL and CE marks.
