General This is a packaged electric element section, using finned rod elements, with a remote sensing control package for modulating the electric elements. The typical installation arrangement is shown in FIGURE 1. The element power is standard 240-volt, single phase. Control is simply supplying the two control wires with 24 volts to turn the unit on.
Installation Requirements 1. All installation work must be performed by trained, qualified contractors or technicians. Electro Industries, Inc., sponsors installation and service schools to assist the installer. Visit our web site at electromn.com for upcoming service schools. 2. All electrical wiring must be in accordance with national electric codes and local electric codes, ordinances, and regulations. 3. Observe electric polarity and wiring colors.
Electrical Hookup 240-volt source – from the model number and nameplate determine KW size and amp draw. According to local codes, building type, wiring length, etc. use appropriate wiring conductor size and source circuit breaker. Connect to the terminal block. Grounding – route and install appropriate size ground conductor between the ground lug and the building service panel ground bus. This must be a conductor size according to the total amp rating of the appropriate unit.
Operational Tips Outlet Temperature Setting – Code “D” The inside circuit board contains a screwdriver switch setting marked Ø through 9. This is usable only for Ø through 7. Unless otherwise specified during the time of order, this unit is equipped with a default “D” chip. This is a broad range temperature with settings at 12° steps. If you would like a more precise temperature setting, the “plug-in chip” can be changed for a temperature range selection.
