  • Page 8: Air Handler Installation

    Please note that each air handler is factory inspected before shipping in order to ensure that every component is operating efficiently. The SCV series air handler is available in several models of various capacities (from 400 to 2200 CFM). Since they are multi-positions units, all models adapt easily to many applications and are suitable for horizontal, upflow and downflow operations as shown in Fig.

  • Page 17 CONTROL BOX REMOTE INSTALLATION When the air handler is used with a remote control box (model # SCV-E-xx2&3x), both assemblies are installed remotely from one another with a maximum distance in between determined by the length of cable harness linking them both (HAR-091 for 120’’ long and HAR-092 for 48’’ long). This alternate configuration does not require any changes to the unit’s high voltage wiring (refer to Fig.

    ELECTRICAL CONNECTION OF THE THERMOSTAT The thermostat must be mounted on a connection box, at approximately 1.5 m (5 feet) above floor level, on a section of the wall exempt from pipes or air ducts. Do not install the thermostat in a location with fluctuating temperature measurements. For example: - close to a window, on an external wall, or close to a door leading outside - exposed directly to the light or heat of the sun, a lamp, a fireplace or any other heat source...
