8.9 Electric Ventilation Damper
The electric ventilation damper is controlled by the ventilation timer. The damper will open when the ventilation timer is activated
to allow fresh air into the structure through the 6” diameter fresh air inlet duct. The electric ventilation damper will remain closed
when the ventilation timer is not activated to prevent over-ventilating the structure when the unit is dehumidifying or recirculating
the indoor air.
The electric ventilation timer operates on 24 VAC from the control circuit.
DO NOT connect high voltage to the damper motor
or damage to the motor may result.
DO NOT force the blade of the damper by hand or damage to the damper motor may result.
The damper opens in one direction only. The damper rotates very slowly, allow sufficient time for the damper to cycle. The damper
will take approximately 1 minute to cycle from closed to open or from open to closed.
If the electric ventilation damper fails to operate:
1. Check that the wiring is correct and that voltage is present at the damper motor.
2. Check for any obstruction inside the damper. If the electric ventilation damper fails to operate after performing these checks, it
must be replaced.
8.10 Condensate Pump Kit
An optional condensate pump kit is available from the factory for use with the Quest 215 Dual. Condensate is automatically
pumped to a remote location when the water level in the pump's reservoir rises to close the float switch.
The pump also contains a safety float switch. The white leads from this switch extend from beneath the pump cover. This switch
should be installed in series with the field wire that connects the blue (#5) lead from the Quest 215 Dual to the blue (#5) lead on
the control panel.
If the pump fails, this switch opens the compressor control circuit and stops water production before the reservoir overflows. The
Quest 215 Dual will continue to ventilate or circulate air as normal, but will not dehumidify until this switch closes.
