Start-Up - Zehnder Rittling RW-260 Installation, Operation And Maintenance Manual

Start-up general
20
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:

without all the proper ductwork
attached, supply and return

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.
