B) Installation 1. Installation of the unit The fitting of DUPLEXVENT R_3 hot air units is described in Appendix D. DUPLEXVENT RA3 units: A minimum required installation space, including HVAC duct connections and access for operating the unit: ● window version ................................................................... 1,65x1,2x2,4 m Minimum distances from building structures: ● in front of the unit................................................................ 0,9 m (*0,6 m) ● from the sides .
2. Installation of CP 08 RD controller For a detailed description of installing and operating a CP08RD incl. recommended operation mode settings see the following document: CP-08 RD CONTROLLER FOR DUPLEXVENT R_3 HVAC UNITS The User’s Manual is supplied with the controller. The controller is installed in a twin-box set in the wall of the building 3.
shut-down (5 minutes by default). The setting can only be made by a person authorized by supplier - a service technician. The ventilation run-down time is automatically reduced depending on outside temperature - the lower the outside temperature, the shorter the run-down time. Immediate start-up without run-down This option is used for starting via an external phase signal from the kitchen (input D4) or a room hygrostat (input D11).
Problem capacity of the heater Possible causes Thermostat fails to start Heat source fails to start Different volumes of fresh and exhaust air Incorrect damper setting Incorrect fan speed setting After connecting the controller and power supply the unit fails to react No voltage in the unit Incorrectly connected conductors Interrupted line The unit was connected to power supply before the CP 08 RD controller was installed 4.
4 Close the door. Re-connect the hot air unit to power supply by switching on the circuit breaker. b) Recirculation filter - cassette 1 Disconnect the hot air unit from power supply by switching off the upstream circuit breaker. 2 Open the door. 3 Slide out the G4 (F7) cassette filter. The direction of air passage through the filter is indicated on the filter by an arrow. Filters in DUPLEXVENT R_3 units should be replaced after approx. 10-12 weeks of operation.
c) Pre-filters (expanded metal mesh) 1 Disconnect the hot air unit from power supply by switching off the upstream circuit breaker. 2 Open the door. 3 Slide out the filter, wash it with warm water (max. 60-70°C) with detergent and let it dry (can be cl eaned in a dishwasher). Slide back in Slide out the filter, wash it with warm water (max. 60-70°C) with detergent and let it dry (can be cleaned in a dishwasher). Slide back in. 2 1 4 Close the door.
3 Slide the heat recovery exchanger out along the guide rails. 4 5 4 Clean the heat recovery block by warm water (max. 60-70°C) with detergent and let it dry. 5 Fit the heat recovery exchanger back in the same position. Install the cover Cleaning the heat recovery exchanger of DUPLEXVENT RB3 warm air units 1 Disconnect the warm air unit from power supply by switching off the upstream circuit breaker. 2 Open the door.
5. General technical data The general technical data of DUPLEXVENT R_3 units are specified in the appendix. Other detailed technical data of DUPLEXVENT R_3 units and the CP08RD controller are shown in technical data sheets and accompanying documents (Installation details etc.).
