SECTION 9 • REPLACEMENT PARTS
Replacement parts for the gas/electric units are available
through local distributors.
A replacement parts list manual is supplied with each
unit. When ordering parts or making inquiries
pertaining to any of the units covered by these
instructions, it is very important to always supply the
complete model number and serial number of the unit.
This is necessary to assure that the correct parts (or an
approved alternate part) are issued to the service agency.
SECTION 10 • OUTDOOR COIL
Period cleaning of the outdoor coil to permit full and
unrestricted airflow circulation is essential. Reduced
airflow through the outdoor coil can shorten equipment
service life as well as increase operating costs.
SECTION 8 • VENTILATION OPTION
ASSEMBLIES
The standard Blank Off Plate (BOP) is installed on the
inside of the vent option door to cover the air inlet
openings which eliminates outside air from entering the
unit.
The optional Commercial Room Ventilator (CRV)
allows up to 50% outside fresh air to be introduced to
the building and includes a built-in exhaust damper.
The CRV complies with ASHRAE Standard 62.1
“Ventilation for Acceptable Indoor Air Quality” .
The optional EIFM-Series Economizer allows for non-
mechanical cooling when the outdoor temperature and
humidity conditions allow. It has automatic controls
that are set to lock out the mechanical cooling and
draw air from outside to cool the structure when the
outside air is below the control set point. This device
can also allow some continuous fresh air to be drawn
into the structure depending on its minimum position
setting.
The optional ERV-Series Energy (Heat) Recovery
Ventilator allows for a continuous change of outside
and inside air. It recovers up to 65% of the energy to
minimize the economic impact of conditioning the
space with fresh air when applying ASHRAE Standard
62.1 fresh air requirements.
