Step-by-Step Installation Guide

Traditional Model (RH-D-A17-90-SR) Installation

1. Mark Your Reference Lines
   Draw a vertical line from your cooktop center to the ceiling. Mark a horizontal line A at 835-935mm above the cooktop surface. This is where your hood will mount.
2. Calculate Chimney Height
   Measure distance X based on your chimney option: 400mm only (no upper line needed), 400+300mm (mark line B at 410-650mm above line A), or 400+390mm (mark line B at 410-740mm above line A).
3. Mark Drilling Points
   On horizontal line A, mark two points 80mm from the center line (160mm apart total). These are your main mounting points. Mark additional points 155mm from center on a line 116mm below line A for bottom support screws.
4. Install Wall Brackets
   Drill 10mm diameter holes at marked points. Insert the supplied wall plugs. Partially screw in the top two screws (5x50mm), leaving about 5mm exposed to hang the hood.
5. Mount the Hood Body
   Hook the rangehood onto the partially inserted top screws. Level the unit carefully, then fully tighten the top screws. Install bottom screws through the hood into wall plugs for secure mounting.
6. Connect Ducting
   For ducted installation, attach either 150mm or 120mm diameter ductwork to the top outlet. Use the reducer flange (supplied) if using 120mm ducting. Secure with appropriate clamps (not supplied). Ensure ductwork runs as short and straight as possible to exterior.
7. Install Chimney Sections
   Attach the lower decorative chimney to the hood body using the supplied 4.2x9.5mm screws. If using an upper chimney section, mount the chimney bracket to the wall at your marked line B, then secure the upper chimney to this bracket.
8. Final Checks
   Reconnect power and test all speed settings. Check that LED lights function properly. Verify the hood is level and all screws are tight.

Slim Model (RH-D-F49-90-SR) Installation

1. Measure and Mark
   Mark a vertical centerline above your cooktop. For the 90cm model, mark two points 538mm apart (269mm each side of center) at your desired mounting height (minimum 650mm above cooktop).
2. Prepare Wall Anchors
   Drill 10mm holes at the marked points. Insert the supplied plastic wall plugs firmly into the wall.
3. Choose Venting Mode
   Before mounting, rotate the venting knob on top of the unit. Turn it to the extraction position for ducted installation or recirculation position if using carbon filters (sold separately).
4. Mount the Hood
   Screw in the top mounting screws partially. Hang the hood on these screws, level it carefully, then insert and tighten all remaining screws including the bottom mounting points.
5. Install Ducting or Carbon Filter
   For extraction mode, connect 120mm diameter ducting to the top outlet with the supplied check valve. For recirculation mode, install optional carbon filters inside the unit at the motor end.
6. Power Connection and Testing
   Plug into a standard Australian power outlet. Test the touch controls at all three speed settings and verify LED lights are working.

Operating Your Rangehood

Control Panel Functions

Traditional Model: Features simple rocker switches for intuitive operation. Press the motor switch to cycle through three speeds (low, medium, high) or turn off. Separate switch controls LED lighting.

Slim Model: Touch-sensitive controls offer a modern interface. Individual buttons for motor on/off, lighting on/off, and three distinct speed settings (low, medium, high).

Choosing the Right Speed Setting

Maintenance & Cleaning

Aluminium Grease Filters

Clean every 2 months for normal use, monthly for heavy cooking. The 5-layer aluminium filters are dishwasher safe or can be hand-washed with mild detergent and warm water. To remove filters, push them toward the back of the hood while pulling down. Some color change over time is normal and doesn't affect performance.

Carbon Filters (Recirculation Mode Only)

Replace every 2-3 months depending on usage. These filters cannot be washed or regenerated. For the slim model, remove grease filters first, then twist the carbon filter counterclockwise to remove from the motor housing.

LED Light Replacement

1. Disconnect power at the wall outlet or circuit breaker
2. Remove the metal grease filters to access the light modules
3. Carefully pry the LED module from its fitting (may require firm pressure)
4. Disconnect the electrical connector
5. Install new LED module (1.5W specifications) and reconnect
6. Test before replacing filters

External Cleaning

Wipe the stainless steel surfaces weekly with a soft, damp cloth and mild detergent. Avoid abrasive cleaners, scouring pads, or harsh chemicals that can damage the finish. Always wipe in the direction of the grain for stainless steel.
