!WARNING!
Remove all power from the heater BEFORE attempting to
replace the Model 4085 emitter.
!CAUTION!
Wear soft, clean, oil-free flannel or plastic gloves when
handling halogen, quartz lamps. Oils and contaminants are
readily transmitted to the quartz by unprotected hands and
can cause premature lamp failure.
Replacement of the Model 4085 emitter is easily performed and takes very little time.
This process is as follows:
1. Remove power to the heater.
2. Remove the two screws holding the heater back plate from the heater housing
using a Phillips screwdriver.
3. Carefully remove the back plate/lamp socket assembly from the heater.
4. Unscrew the lap from the lamp socket by turning counter-clockwise until the
lamp is removed from the socket.
5. Screw the new lamp into the socket by turning clockwise until ‘hand tight’.
6. Carefully place the lamp/lamp socket/back plate assembly into the heater
housing taking care to insert the lamp into the lap guides mounted within the
lamp housing.
7. Rotate the back plate until the notch on the back plate seats into the
corresponding key on the heater housing.
8. Place the back plate screws in their original positions and tighten (until snug)
using a Phillips screwdriver.
