Exposed unit touch-up
and repainting
Exposed cabinet units will be furnished
with an epoxy powder coated paint
finish. Small scratches in the finish
may be repaired with touch-up spray
paint available from the factory.
Proper safety procedures should
be followed regarding ventilation
and personal safety equipment
when using spray paint. Follow the
manufacturer’s directions for the
products being used.
To repaint the factory powder coat
finish, prepare the surface by lightly
sanding with #280 grit sand paper or
#000 or #0000 fine steel wool. The
surface may also be wiped with a
liquid surface etch cleaning product.
These items should be available
at most paint product stores. It
should be noted that the more care
taken during this process, the more
effective it will be.
After this preparation is finished,
the factory finish should provide
excellent adhesion for a variety of
air dried top coats. Enamel will give
a more durable, higher gloss finish,
while latex will not adhere as well
and will give a dull, softer finish.
Top coats involving an exothermic
chemical process between two
components such as epoxies and
urethanes should be avoided.
All standard colors including primer
can be painted over. If the installing
contractor chooses not to paint over
the primer color, the factory cannot
match primer color on future orders,
potentially causing color match
issues in the field.
Factory touch-up spray paint may
require a number of light coats to
isolate the factory finish from the
quick drying touch-up paint.
Start-up general
Before beginning any start-
up, the start-up personnel
should take the time to
familiarize themselves with
the unit, options, accessories
and control sequence to fully
understand how the unit should
operate properly under normal
conditions. All personnel should
have a good working knowledge
of general start-up procedures.
The building must be completely
finished before attempting to
start-up the equipment, including
doors, windows and insulation.
All internal doors and walls
should be in place. In some
cases, the internal decorations
and furniture may influence
overall system performance.
The entire building should be
as complete as possible before
beginning any system balancing.
The initial step is to visually
inspect all of the equipment,
plenums, connecting ductwork
and piping. Ensure that all
systems are properly installed
and supported and that all
construction debris or foreign
objects have been removed from
the equipment.
Each unit should be checked for:
n
Free blower wheel operation
n
Loose wires
n
Loose or missing access
panels or doors
n
Filter installed, clean and of the
proper size and type
n
Drain pan free of debris
n
Proper ductwork is attached
n
Supply and return grilles are in
place and secure
Except as required during start-
up and balancing, no fan coils
should be operated without all
the proper ductwork attached,
supply and return grilles in place
and all the access doors and
panels secured in place.
Failure to do so could result in
damage to the equipment or
building and furnishings and will
void the manufacturer’s warranty.
