Indoor-Air (Conditioned Supply Air) System The VEB/VHB series unit may be applied in either a free return air configuration or a ducted return air configuration. The supply air path is intended to be ducted. The design and construction of the indoor-air system must provide adequate air distribution to ensure comfort levels throughout the structure. The combined pressure losses of the return and supply air paths must not exceed the external static capabilities of the system at the design airflow (See Table 2). If the unit is installed in a closet behind a door and the return air louver or grille is directly opposite the unit RA opening, 2in. clearance is required between the front of the unit and the back side of the louver or grille. If the louver or grille is located elsewhere on the door so it is not directly in front of the RA opening, a minimum of 7-in. clearance is required between the front of the unit and the back side of the door. The minimum "net free open area" required for the RA louver or grille is listed in Table 2.

Filters are not supplied with units configured for ducted return. 2) Electrical DANGER: Electrical shock hazard. Turn OFF electric power at the fuse box or service panel before making any electrical connections and ensure a proper ground connection is made before connecting line voltage. Failure to do so can result in property damage, personal injury and/or death. A. Grounding CAUTION: The unit must be electrically wired and grounded in accordance with all state and local codes, national electric code, and NFPA 70. Unit and controls will NOT operate unless properly grounded. A ground lug is provided for ground connection. Use only approved copper wire and connectors from unit to service panel. B. Power Supply NOTE:Line voltage circuit is completely factory wired.Make all line voltage connections inside circuit breaker junction box. The circuit breakers or fuses used for branch circuit protection should be UL recognized. If circuit breakers are used, the circuit breaker for the compressor circuit must have a UL HACR rating. If fuses are used, the fuse for the compressor circuit MUST be time delay type. CAUTION: Units are dual voltage rated 208-230/1/60. The 24V control transformer must be connected for either 208V or 240V power source for proper operation. Line voltage must not exceed 253V or go below 197V. The transformer connection must be changed for 208V operation. Depending on auxiliary heater size, unit must be supplied with 2 or 3 separate 208V or 240V circuits from structure’s fuse box or service panel. Each circuit is internally connected to a circuit breaker located in the unit control box located at the front center of the unit. Refer to Table 4 and Table 5 for required circuits and recommended wire size for each circuit.
