Installation & OpérationInstallation• Easy mounting with hanging rails and
brackets• No moving parts• Very little maintenance• Easy access from the front for coil cleaning.• No electrical connections• Inexpensive terminal controls
Operation• High chilled water temperature 14-16°C
(57-61°F)• Primary ‘fresh’ air quantity tailored to suit
ventilation requirements.• Self regulating• VAV for tight temperature control
