IMPORTANT SAFETY
(CONTINUED)
11. To prevent a possible fire, do not block air intakes or
exhaust in any manner. Do not use on soft surfaces,
like a bed, where openings may become blocked.
12. A heater has hot and arcing or sparking parts inside. Do
not use it in areas where gasoline, paint, or flammable
liquids are used or stored.
13.
Avoid the use of an extension cord because the
extension cord may overheat and cause a risk of fire.
However, if you have to use an extension cord, the cord
shall be No. 16 AWG minimum wire size (and rated not
less than 688 watts for FFH-512A; 1125 watts for FFH-
912B). The extension cord must also be a 3-wire cord
with a bonding (grounding) type cord and plug
connector.
SAVE THESE INSTRUCTIONS
CAUTION: DISCONNECT POWER BEFORE INSTALLING OR
REPLACING TUBES. THESE ELEMENTS CAN AND SHOULD BE
INSTALLED PRIOR TO MOUNTING HEATER.
Caution: Do not handle the element(s) with bare hands, gloves
or other material that may contain grease, moisture, etc. Such
handling may impair the operation of the heater. Handle the
elements only by the ends or with the packaging material around
the elements. Remove any fingerprints, grease or dirt with
alcohol and a soft cloth. Allow elements to dry.
MODEL FFH-912B (Refer to Figure 1.)
1. Cut pigtail leads to approximately 2 1/2" in length.
2. Turn compression screw counterclockwise to loosen (do not
remove) clip in porcelain socket well. Insert the pigtail lead
between clip and well, then screw clockwise until pigtail is firmly
secured. Be sure to leave some slack on the pigtail.
3.
Install the end caps and lamp guard.
Always disconnect the heater from the power source before
performing any service or maintenance.
Periodically clean the
reflector with a dampened soft cloth, using a mild detergent. Rinse
with water and wipe dry with a clean, soft cloth. Periodically wipe
the quartz tube(s) with alcohol and a clean, soft cloth. Allow to dry.
Repair or replace damaged cordsets immediately
.
INSTALLATION OF HEATING ELEMENT
MODEL FFH-512A (Refer to Figure 2)
1. Loosen screws on ceramic insulators.
2. Position quartz tube in slots.
3. Carefully wrap pigtail of quartz tube clockwise around screw and
tighten screw. Be sure to leave some slack on pigtail. Do not
put pressure on the tube by making the pigtail too short.
4. Cut off excess pigtail wire.
5. Install the end caps and lamp guard.
INSTALLATION
NOTE: Heater must be mounted with a minimum 3" from
ceiling, 24" from a vertical surface and a minimum 6 ft.
from the floor.
1. Cut chains to desired mounting length.
2. Attach chains to heater with "S" hooks and suspend from
ceiling. In spot heating workstations, two heaters are
recommended to obtain good pattern coverage and
overall comfort.
3. Plug cord set into a 120 volt, 60 Hz. Bonded (grounded)
receptacle. Be sure the power source conforms to the
heater requirements.
NOTE: Quartz element(s) must be in a horizontal, or near
horizontal position when energized. Failure to do so will
shorten element life.
OPERATION
Heater should be plugged into a properly bonded
(grounded) receptacle. Ensure that the current does not
exceed the rating of the circuit.
On Model FFH-912B, elements are energized or de-
energized with individual toggle switches.
HEAT CONTROL
Intensity of the work area heat level is controlled by
wattage directed on the work area. Wattage levels in the
working area can be increased or lowered by switching ON
or OFF some of the heating elements. Model FFH-912B
has two heat sources (quartz tubes), and turning off one
tube will not affect the direction of heat. Cycling is an
alternate of ON/OFF switching and can be accomplished
readily with an Input Controller or Percentage Timer. Both
these control devices offer smooth heat level changes
responsive to the localized heat requirements. Thermostats
built for infrared heat loads will control heat levels by
response to the surrounding air temperature.
