SECTION TWO — Start Up
must be wired in strict accordance with the wiring
diagram that appears on the unit. Failure to do so could
result in personal injury or damage to components, and
will void all manufacturer’s warranties.
The fan motor(s) should never be controlled by any
wiring or device other than the factory-furnished switch
or thermostat/switch combination without factory
authorization. Fan motor(s) may be temporarily wired for
use during construction only with prior factory approval in
strict accordance with the instructions issued at that time.
Units with optional factory-furnished and installed
aquastats may be shipped with the aquastats mounted on
a coil stub-out. Remove the aquastat before installation of
a valve package. Consult the factory piping diagram in the
approved submittals for proper location when reinstalling
the aquastats. If the valve package is field-furnished, the
aquastat must be installed in a location where it will sense
the water temperature regardless of control valve position.
A bleed bypass may be required to guarantee proper
aquastat operation.
All field wiring should be done in accordance with
governing codes and ordinances. Any modification of the
unit wiring without factory authorization will void all of the
factory warranties, and will nullify any agency listings.
The manufacturer assumes no responsibility for any
damages and/or injuries resulting from improper field
installation and/or wiring.
Exposed Unit Touch-up and Repainting
Exposed cabinet units may be furnished with a baked
enamel finish. Small scratches in this finish may be
repaired with touch-up paint available from the factory.
Some colors of touch-up paint are available in aerosol
containers and all touch-up paint is available in pint, quart,
and gallon cans. Contact the factory for availability.
Proper safety procedures should be followed regarding
ventilation and safety equipment. The manufacturer’s
directions should be followed for the products being used.
To repaint the factory-baked enamel, the finish should be
prepared by light 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 such as
“No Sand” or “Pasceo.” These items should be available
at most paint product stores. It should be noted that the
more conscientiously this preparation is done, the more
effective it will be.
After this preparation is accomplished, 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.
Factory aerosol touch-up paint may require a number
of light “dust coats” to isolate the factory-baked enamel
finish from the quick drying touch-up paint.
SECTION TWO – Start Up
General
Before beginning any start-up operation, the start-up
personnel should familiarize themselves with the unit,
options and accessories, and control sequence to
understand the proper system operation. All personnel
should have a good working knowledge of general
start-up procedures and have the appropriate start-up
and balancing guides available for consultation.
The building must be completely finished including doors,
windows, and insulation. All internal walls and doors
should be in place and in the normal position. In some
cases the interior 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 in any start-up operation should be a final
visual inspection. All equipment, plenums, duct-work, and
piping should be inspected to verify that all systems are
complete and properly installed and mounted, and that no
debris or foreign articles such as paper or drink cans are
left in the units or other areas.
