3.0 SPECIAL NOTICES
The following special notices highlight important information in the installation and maintenance sections. Each serves a special purpose, and is displayed in the format shown:
This symbol indicates a potentially hazardous situation, which, if not avoided, can result in personal injury or damage to the equipment.
This symbol indicates a potentially hazardous situation, which, if not avoided, may be a shock hazard.
This symbol indicates an imminently hazardous situation, which, if not avoided, could result in death or serious injury.
2.3 CONSTRUCTION
The XDF explosion-proof duct heater features heavy-walled car­bon steel finned tubular heating elements with electroless nickel plated finish to provide safe, efficient, low temperature heat trans­fer. Standard units have a painted carbon steel duct section with mounting holes provided for attachment to the duct section.
XDF heaters feature the unique Caloritech™ patented x-Max® copper-free aluminum extruded terminal housing. A track-and-trol­ley system and threaded covers on each end allow easy access to wiring terminal connections.
Units are suitable for mounting in a horizontal duct section only.
4.0 PRE-INSTALLATION
4.1 Inspect the heater for possible damage due to shipping
and handling. Claims for shipping damages shall be placed with the carrier.
4.2 Check the heater nameplates to ensure that the heater area
classification and temperature code are suitable for the hazardous area classification.

as ordered and are the same as the electrical power supply available.
DO NOT CONNECT THE HEATER TO AN ELECTRICAL SUPPLY VOLTAGE OTHER THAN THAT SHOWN ON THE PRODUCT NAMEPLATE.
REVIEW THIS MANUAL AND ALL DRAWINGS CONTAINED WITHIN PRIOR TO INSTALLATION, WIRING, OR OPERATION OF THE HEATER.
5.0 DIMENSIONS AND INSTALLATION
The heater must be installed by qualified personnel in strict compliance with the electrical code and hazardous locations standards.
THE HEATER MUST BE INSTALLED IN A HORIZONTAL DUCT SECTION ONLY. IMPROPER ORIENTATION OF THE HEATER COULD AFFECT THE SAFE AND RELIABLE OPERATION OF THE HEATER.
5.1 HEATER DIMENSIONS
Table 1 - Heater Dimensions and Weights (See Fig. 1)
MI289 REV.1 Page 2 of 4

5.2 INSTALLATION
5.2.1 The heater is designed for installation in a horizontal duct
with the terminal boxes at the side. Improper orientation of the duct heater could effect the safe and reliable operation of the heater.
Note: All dimension in millimeters (inches in brackets).
IMPROPER ORIENTATION OF THE HEATER COULD AFFECT THE SAFE AND RELIABLE OPERATION OF THE HEATER.
NEVER USE THE CONTROL HOUSINGS FOR LIFTING OR MOVING THE HEATER AS THIS COULD DAMAGE THE HEATING ELEMENTS AND CONDUIT.
5.2.2 To install the heater, bolt the heater assembly into the
customer supplied ducting system. If necessary, reinforce with duct supports to support the heater weight as shown in Table 1. Note proper orientation of heater, as shown by the "TOP" and "AIRFLOW" labels.
5.2.3 An explosion-proof pressure differential switch has been
supplied loose. Install the switch in a suitable location and with proper orientation. Install tubing between the switch and the duct using the appropriate port on the switch body (sensing high or low pressure). Consult manufacturer's operation instructions included with this manual.
THE PRESSURE DIFFERENTIAL SWITCH IS A CRITICAL SAFETY COMPONENT. IMPROPER INSTALLATION OF THE SWITCH MAY RESULT IN HAZARDOUS CONDITIONS.
