Installation Operation Maintenance

InstallationConnection of ductnetworkSupply and return openings havecurb flanges provided for easy ductinstallation. It is recommended toinsulate the circumference of thecurb after the unit is mounted toprevent condensation.CAUTION! : All ductwork must berun and attached to the curb flangesbefore the unit is set into place.Guidelines for ductworkconstruction- Connections to the unit should bemade with 7.5 cm canvasconnectors to minimize noise andvibration transmission.- Elbows with turning vanes orsplitters recommended tominimize air noise and resistance.- The first elbow in the ductworkleaving the unit should be nocloser than 60 cm from the unit, tominimize noise and resistance.Attaching horizontal ductwork tounit- All conditioned air ductworkshould be insulated to minimizeheating and cooling duct losses.Use minimum of 5 cm ofinsulation with a vapor barrier. Theoutside ductwork must be weatherproofed between the unit and thebuilding.- When attaching ductwork to ahorizontal unit, provide a flexiblewatertight connection to preventnoise transmission from the unitto the ducts. The flexibleconnection must be indoors andmade out of heavy canvas.Note: Do not draw the canvas tautbetween the solid ducts.Condensate drain pipingEach Voyager III unit is equippedwith a PVC 1 1/4" femalecondensate drainage connector.Since the drainage connector is onthe negative pressure side of thefan, a condensate trap must beinstalled. Install a P trap on the unit,following the instructions inFigure 6.Slope the drainage pipe down atleast 1 % to ensure an adequatecondensate flow.Check all the condensate drainagepipe fittings comply with theapplicable construction regulationsand waste disposal standards.Figure 6 - Condensate trap installation43752351.
