Qmark IUH - Industrial Unit Heater - Manual (Page 4)

MAINTENANCE INSTRUCTIONS
In order to maintain the efficiency of the unit heat, it should be
inspected periodically and any dirt that may have accumulated
should be removed from the heating element, fan blades and
motor using a soft brush or a vacuum cleaner.
5 kw & 7.5 kw Heaters: The heating element is accessible by
removing the louvered bezel, front section of the heater. Loosen,
but do not remove, 4 recessed head screws located to the rear of
louvers (Figure 4). Grasp bezel on both sides, lift up and pull out,
disengaging bezel. After servicing the unit, reverse this procedure
to replace bezel.
To service the motor, remove the rear wire safety grille (Figure 5).
10 kw through 30 kw Heaters: The heating element surface and
fan motor area are accessible by removing the left or right side
panel of heater. To do this, open the hinged control box cover, and
then remove the two screws that hold the bottom of the side panel.
Lift out that end of the side panel and then pull down for removal.
After servicing the unit, reverse the unit, reverse this procedure to
replace the side panel.
NOTE: When a new heater is first energized, a light smoking
may be noticeable. This is caused by burning off any residue
oil left on the heating element during manufacturing. This
condition will disappear in a few minutes after heater is put
into operation.
