Application Data

Location Requirements To achieve optimum performance and trouble-free service, it is essential that the proposed installation site meet with the location and space requirements for the model being installed. The clearances recommended are nominal for the safe and efficient operation and maintenance…

Where cross-winds may occur, any ductwork must be

supported to prevent side loading on the unit. If the ducts from two or more fans are to be combined into a common duct, back-flow dampers should be fitted in the individual fan ducts. This will prevent re-circulation of air when only one of the fans is running. Units are supplied with outlet guards…

Installation of Vibration Isolators

An optional set of vibration isolators can be supplied loose with each unit. Pipework Connection The following piping recommendations are intended to ensure satisfactory operation of the unit. Failure to follow these recommendations could cause damage to the unit, or loss of performance, and may…

Connection Types and Sizes

D5=1.447 x L Standard pipework connections are of the Victaulic groove type. Where: D = minimum pipe internal diameter (cm) L = length of pipe (m). For connection sizes relevant to individual models refer to the physical data tables in this manual. Heat Recovery System If relief pipework is common…

Remote Emergency Stop Device

Control Wiring - System Inputs If required, a remote emergency stop device may be wired into the unit. This device should be rated at 20 amps, 110 V, AC-15. The device should be wired into terminals L and 5 in the power panel after removing the factory fitted link. All wiring to the control terminal…
