Unit Options RT -SVX1 9A-E4 40 Hot wat er coil (Down flo w units only) In order to prevent water to freez e up in the coil during unoccupied period or shutdown limited period, a thermostat opens when there is a risk of freeze-up. The services of a water treatment specialist are recommended if water used can cause scaling deposits or erosion.
Unit Options 41 R T -SVX1 9A-E4 Electr ic Heater Electric heaters are fitted on the fan disc harge. Heaters have two heating stages and provided with two types of overheat thermostats: • Automatic reset thermostats whic h stop the electric heater when the air temperature rises to 7 6°C.
Unit Options RT -SVX1 9A-E4 42 0 - 25% fr esh air hood The 0-25% fresh air hood allows to introduce fresh air into the unit. This is a manual device fitted on the bac k of the unit, siz ed for a maximum of 25% of the nominal rooftop air flow . This option includes for the hood itself, a wire mesh and a slidable damper .
This option includes exhaust hoods and gravity dampers located in the return air section (Figure 22). When the pressure of the building increase, the gravity dampers open and relieve air to the outside. If the return air duct pressure drop is higher than the building overpressure, the gravity dampers will not open.
