D – Layout and Components Layout and Components The general layout and components location is the same for all dehumidifiers of current type, however some may vary, based on the dehumidifier’s specific options – refer to submittal documentation. Pic. D.1 below shows all/most available options, some of which may not be present on your dehumidifier. -
Page 13: Control System D
D – Layout and Components Main Blower (1) is in the main blower compartment next to the Main Electric Panel (2) and Compressor Compartment (3). Min Outdoor Air (OA) Opening (4) is optionally equipped with a motorized damper and filter(s). The Manual OA Damper (5) is usually used to set proper amount of outdoor air intake. - Page 14 D – Layout and Components Pic. D.4 RA Combo Sensor (21) measures temperature and humidity of the pool room air (Return Air) entering the dehumidifier. It is located at the main filter rack. OA Temperature Sensor (22) measures outdoor air temperature; it’s located at the OA filter rack. As an option, the combo sensor (instead of regular thermistor) can be installed at the OA intake to measure both the temperature and humidity of the outdoor air.

Page 18: Chapter E - Sequence Of Operation
E – Sequence of Operation Sequence of Operation The dehumidifier’s ventilation system establishes the required airflow through the dehumidifier. The control system compares air temperature and humidity to their desired values (set points) and proceeds to dehumidify, cool or heat the recirculating air. If the dehumidifier is equipped with the pool water heating option, the pool water temperature is compared to its set point and pool heating is provided if required. - Page 19 E – Sequence of Operation Compressor Circuit Operation Piping schematic for compressor circuit is shown on Pic. E.1. When a demand requires the compressor to operate, the following sequence occurs: Once blower operation, related safeties and timers are confirmed by the control system, the pump down solenoid valve opens and once pressure stabilizes, the compressor starts.

Page 20: Space Heating
E – Sequence of Operation Space Heating When premise air temperature drops below the set point, the dehumidifier control system issues a call for Space Heating Mode and engages space heater (electric heater, hot water coil with valve, gas boiler etc.) by sending space heating signal, respective to space heater control type - on/off, variable (0-10VDC), etc. - Page 21 E – Sequence of Operation This page is left blank...
