Spec Air Series Technical Manual 3 Cambridge Air Solutions
HAZARD SUMMARY
The following safety precautions apply to the
installation, operation, and maintenance of the
equipment described by this technical manual.
WARNING:
Any unauthorized modification of this
equipment shall void the warranty.
WARNING:
Only qualified personnel should attempt
installation, service, and repair of this
equipment. Use extreme caution and observe
safety regulations at all times. Obey applicable
plant and OSHA safety regulations.
WARNING:
Recirculation of room air is not permitted.
Adequate building relief shall be provided so as to
not over-pressurize the building when the ventilation
air heating system is operating at its rated capacity.
It should be noted that this can be accomplished by
taking into account, through standard engineering
methods, the structure’s designed infiltration rate, by
providing properly sized relief openings, by
interlocking a powered exhaust system, or by a
combination of these methods.
If the failure or malfunction of this unit creates
a hazard to other fuel burning equipment in
the building (e.g. when the unit is providing the
ventilation air to a boiler room), the unit is to be
interlocked to open inlet air dampers or other such
devices.
If the unit is installed such that an inlet duct is
utilized, the duct system must be purged with at
least four air changes prior to an ignition attempt.
IMPORTANT
