NOTE:
If the holes provided on the bottom of the unit
and the bottom of the wall mounting plate do not align,
remove the unit and re-install The holes on the bottom
channel of the wall mounted plate must be on the bottom. |
|
|
2.
Set air velocity control louvers so that the air stream
just reaches the floor to prevent
turbulent mixing of
inside and outside air. |
|
|
6.
The discharge must be free and clear of any
obstacles for optimum performance. |
|
|
3.
The unit is to be installed such that the airflow is
unobstructed. |
|

|
|
| ROUTINE
MAINTENANCE |
WARMING
- TO REDUCE THE RISK OF FIRE,
ELECTRICAL SHOCK OR INJURY TO PERSONS,
OBSERVE THE FOLLOWING: |
|
It
is imperative to keep the fans clean, as they eventually
become coated with residue. Dirty fans will lower the
efficiency and eventually throw fans out of balance
which
can shorten the life of the blower wheels and cause
undue
wear on the bearings. The time between cleanings depend
upon the type and amount of particles floating in the
air.
Under normal circumstances, the system will require
cleaning only about once a year. |
|
Use
this unit only in the manner intended by the
manufacturer, if you have any questions, contact the
manufacturer. Before servicing or cleaning the unit,
switch power off at service panel and lock to prevent
power from being switched on accidentally. Servicing
an energized air curtain presents a risk of fire, electric
shock or injury to persons. DO NOT attempt any
maintenance unless the electric supply has been
completely disconnected. Installation work with all
electrical wiring must be done by qualified person(s)
in
accordance with all applicable codes and standards.
When cutting or drilling into wall or ceiling, do not
damage electrical wiring and other hidden utilities. |
