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.
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.
4.3 Verify that the nameplate voltage, phase, and wattage are
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.
