Qmark SED Series - Fan-Forced Wall Heaters - Manual (Page 3)

INSTALLATION OF HEATER
ASSEMBLY INTO BACK BOX
1. Re-install fan deck using two screws.
2. Connect field supply wiring to heater pigtail leads (See figure 4).
Connect field ground wire to green ground lead wire.
3. Install front cover. Push on thermostat knob.
CHECK OPERATION AND SET THERMOSTAT
1. Switch on power supply to heater.
2. Rotate thermostat knob fully clockwise. Heating element and fan should
come on, causing warm air to flow from discharge grille.
3. Allow heater to operate until room is comfortable, then rotate thermo-
stat counter-clockwise until thermostat clicks. The unit will continue to
cycle on and off to maintain temperature.
4. Increase or decrease the setting as required until the desired room tem-
perature is maintained.
For best results, the heater should be left “ON” constantly during the
heating season as the thermostat, when properly set, will maintain the
desired room temperature. In the counter-clockwise position, the heater
will remain off. This unit was shipped with a plug button to render the
thermostat tamper resistant. Remove the thermostat knob and insert
plug button in clearance hole guide.
For ceiling mounted units, a remote wall mounted line voltage thermostat
may be installed to control the unit. Follow instructions for the wall ther-
mostat. Turn the thermostat knob on the unit to full clockwise position for
maximum heat, remove the knob and insert plug button in clearance hole
guide. Set your wall thermostat to desired set point.
OPERATION NOTICE
Your heater is equipped with an automatic reset limit control that will
automatically turn the heater OFF to prevent a fire if the heater
overheats. Should this occur, the indicator light will illuminate and will
continue to shine until the limit resets.

To insure proper grounding of heater and prevent a possible electric
shock, the field supply ground wire must be attached to heater green
ground lead wire.
CAUTION
!
To prevent possible wiring damage, cut excess supply wires inside
backbox to provide approximately 6” (152 mm) for connection to
heater leads. After connections are made, make sure connections
are tight and all wiring is positioned away from fan blade and heating
element.
CAUTION
!
THE ILLUMINATED INDICATOR LIGHT SIGNIFIES THE HEATER HAS
BEEN SUBJECTED TO SOME ABNORMAL CONDITION CAUSING IT
TO OVERHEAT. CHECK HEATER TO INSURE THAT IT HAS NOT BEEN
BLOCKED IN ANY MANNER (IF SO, REMOVE BLOCKAGE). IF THERE
IS NO INDICATION OF BLOCKAGE, IT IS RECOMMENDED THAT
HEATER BE CHECKED BY A REPUTABLE ELECTRICIAN OR REPAIR
SERVICE TO INSURE THE HEATER HAS NOT BEEN DAMAGED.
