Installation Manual for Ximax Designer Radiator

Quick guide from the manual

Before beginning the assembly of your Ximax designer radiator, ensure you have read the instructions carefully. The installation must be performed by a qualified plumber or competent specialist. Always wear protective clothing, such as gloves and reinforced work shoes, during the process.

Required tools: Phillips screwdriver, flat screwdriver, tape measure, wrench, drill bit, and drilling machine.

Important safety and preparation:

• Do not dispose of packaging until all small parts (brackets, mounting accessories) are secured.
• Ensure the wall is suitable for mounting; supplied wall plugs are for solid masonry only.
• Check for hidden water, electric, or gas lines before drilling.
• Maintain a minimum distance of 150 mm between the floor and the bottom of the radiator for efficient ventilation.

Scope of delivery

The standard package includes:

• 1x Radiator
• 1x Air vent (A)
• 1x Blanking plug (B)
• 4x Masonry wall plugs (C)
• 4x Screws (D)
• 4x Washers (E)
• 4x Wall brackets

Connection options

The manual provides various connection schemes for vertical and horizontal tube, panel, and profile radiators. Ensure you have the appropriate connection fittings before starting. Options include standard connections, offset/center connections, and side connections.

Assembly instructions

1. Drill 4 holes using the dimensions specified in the assembly dimension table (approx. 60 mm depth, 8 mm diameter).
2. Insert wall plugs (C) into the holes (solid walls only).
3. Attach the screw (D) and washer (E) to the bracket. Do not overtighten.
4. Check for a baffle inside the horizontal tubes. If present, it must be at the bottom. If clear, installation direction is universal.
5. Hang the radiator on the brackets.
6. Install the air valve (A) and blanking plug (B) in the upper threaded openings.
7. Connect flow and return valves (not included) using watertight seals (e.g., PTFE tape).
8. Filling and venting: Open the air vent, slightly open the inlet valve (10%), and allow the system to fill slowly. Once filled, close the air vent, open both valves fully, run for 2 hours, then vent again to remove remaining air.

Care and use

After installation, the system must be thoroughly rinsed to flush out debris and then vented. It is recommended to add a suitable inhibitor to the central heating system to prevent internal rust and limescale. Clean the radiator only with a soft, damp cloth; avoid scouring pads or chemical cleaning agents.

Troubleshooting

If pipes are not warm, vent the radiator again. If tubes remain cold, the radiator may have been filled too quickly; try draining and refilling slowly. If the radiator heats unevenly or takes a long time to heat, it may be installed upside down (check the baffle position). For electric radiators, a small amount of water discharge on first use is normal; if panels do not heat, top up the radiator by placing it on its side and adding water through the top side nut.
