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.

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

Periodic 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.
