‡ Models with suffix “T” added (480 volts only) are equipped with a transformer, 480 volt primary — 120/240 volt secondary.
‡ Models with suffix “R” added are equipped with a relay (Example: UB-1002E-R 240 volt or 480 volt — 3 phase only).
MOUNTING
WARNING: Hazard of Electric Shock. Disconnect all
power before installing heater.
Note: These heaters are designed for wall or ceiling mounting
only. Other modes of mounting voids factory warranty.
1. Height above floor
A. In areas where ceiling height is more than 12 feet, recommended mounting height is approximately 10 feet to underside of heater.
B. For ceiling heights of 12 feet or less, maximum mounting
height is determined by use of ceiling mounting brackets
offered for these heaters. Minimum spacing to ceiling is 3”
(see Figure 2).
© 2010 Chromalox®, Inc.
C. In either case, minimum mounting height is 7 feet from
floor to bottom of heater (see Figures 1 and 2).
2. Spacing to adjacent walls
A. Rear of case to back wall 4-7/8” minimum (see Figure 2).
B. Side of case to side wall 6” minimum (see Figure 2).
3. If two or more units are operated in the same enclosed space,
their discharges should be directed to aid in development of
mass air movement for uniform heat dispersal.
4. Controlling thermostats to individual heaters should be
mounted at shoulder height on inside walls or columns.
WIRING
Note: All wiring should be done in accordance with local codes
and the National Electrical Code by a qualified person.
WARNING: Hazard of Electric Shock. Any installation involving electric heaters must be effectively
grounded in accordance with the National
Electrical Code to eliminate shock hazard.
1. Connect heater according to the voltage and frequency specified on the nameplate and using the appropriate wiring diagram
(Figures 3 thru 7).
Note: Be sure to check voltage rating of the fan motor which is
either 120, 208 or 240 volt, single phase since heater circuit could
be 480 volts, single or three phase.
2. If an external transformer is used to step down the voltage for operating the fan motor, use appropriate wiring diagram (Figures 3, 5
or 7).
3. Heaters are not provided with a control switch and should be
controlled by a magnetic contactor (integral or external) and a
separately mounted thermostat. External contactor is not necessary with heaters having a model number suffixed with the
letter “R”.
4. Protection against overheating is provided by an internal automatic thermal cutout which opens the electric circuit if the normal air-flow is restricted or stopped. Cutout automatically
energizes heater on removal of the obstruction.
WARNING: Users should install adequate back-up
controls and safety devices with their electric
heating equipment. Where the consequences of
failure may be severe, back-up controls are essential. Although the safety of installation is the
responsibility of the user, Chromalox will be glad to
make equipment recommendations.
OPERATION
DANGER:
1. Do not restrict air-flow through the heater by
placing fabric or other obstructions in front of or
behind the heaters. With some combustible
materials, the resulting high discharge temperatures could cause a fire.
2. This heater is not intended for use in hazardous
atmospheres where flammable vapors, gases, liquids or other combustible atmospheres are present
as defined in the National Electrical Code. Failure
to comply can result in explosion or fire. For these
applications see PDS CXH-EP (PF305).
MAINTENANCE
WARNING: Turn off all power to service heater. Do
not attempt to service heater while unit is operating
as there is hazard of electric shock, injury from
operating fan and burns from hot heating elements.
1. Fan motors in these heaters are provided with sealed ball bearings, factory lubricated, requiring no further lubrication under
normal service conditions.
2. Following long periods of idleness, heater should be vacuumed
before start-up, to remove accumulated combustible particles
which otherwise may smoke or incinerate on initial heat up.
3. Periodically inspect all electrical connections and terminals to
avoid electrical wiring difficulties. Inspect all wiring for frayed
or worn insulation.
