Warning
Explosion Hazard.
Improper configuration can cause fuel buildup and
explosion. Operators of this display may move fuel and/
or air actuators to positions that can create hazardous
burner conditions. Improper user operation may result
in PROPERTY LOSS, PHYSICAL INJURY or DEATH.
The S7999D System Display device is to be used only
by experienced and/or licensed burner/boiler operators
and mechanics.
Warning
Electrical shock hazard, can cause personal injury
or loss of life, including property damage.
** All electrical wiring to the boiler and controls must be
protected from ingest of water and be properly grounded
and bonded according to CEC part I CSA 22.1 & NEC
NFPA 70.
SAFETY FEATURES :
The S7999D contains software that incorporates many
features that are designed to guide you safely through the
commissioning process. Safety, however, is your responsibility.
Read all documentation carefully and respond appropriately
to all error messages.
Be aware that as you command the R7999 to open and
close actuators, the R7999 is designed to prevent you
from opening or closing them too rapidly. When any of the
system actuators are below 20% of their open position, the
R7999 effectively limits any actuator from traveling more
than three degrees without moving the other actuators in
the system. When all the actuators are over 20% of their
open position, the limit increases to 10 degrees.
