A practical Marco FRIIA CS setup guide covering plumbing requirements, commissioning steps, and checkpoints for reliable hot, chilled, and sparkling water in a cafe.

Quick answer

Install the Marco FRIIA CS as an under-counter system with a dedicated cold water supply, adequate drainage, and proper ventilation, then commission it by flushing the lines and verifying stable hot, chilled, and sparkling output before service. Follow the steps below in order and use the checkpoints to catch common mistakes early.

Why under-counter placement and ventilation matter

The FRIIA CS is designed to sit under the counter, which keeps your service area clear but puts the unit in a confined space. Chilled and sparkling water production generates heat, so the cabinet needs enough airflow to prevent the system from working harder than necessary. Before you finalize the location, confirm that the cabinet has ventilation openings or a fan, and that the unit is not boxed in by stored items.

Also check that the counter cutout and tap position give you room to route the bundled lines without sharp bends. A tight bend can restrict flow or damage tubing, which is a common cause of poor sparkling performance.

Water supply and drainage decisions

The FRIIA CS needs a potable cold water supply and a drain connection. If your cafe already has a water filter for espresso machines, you can often tap into the same filtered line, but verify that the filter is rated for the flow and that it does not drop pressure below the system's requirement. The catalog does not list a minimum inlet pressure, so check the installation manual or ask your supplier before assuming your existing line is adequate.

For drainage, a gravity drain or a suitable waste connection is required. Do not run the drain uphill or into a shared line that can back up. A dedicated drain is safer for sparkling water because the system may discharge water during operation.

Step-by-step Marco FRIIA CS setup

1. Isolate and prepare the water supply: Turn off the existing water supply and install a dedicated cold water feed with a shut-off valve near the unit. If you are using a filter, flush it according to the filter manufacturer's instructions before connecting to the FRIIA CS. Common mistake: connecting the system before flushing the filter, which can send carbon fines into the unit. Checkpoint: confirm the supply is cold, filtered, and has a working shut-off valve before proceeding.
2. Position the unit and connect drainage: Place the FRIIA CS in the under-counter cabinet with the specified clearances for ventilation. Connect the drain line with a continuous fall to a suitable waste point. Do not reduce the drain diameter or use a flexible hose that can kink. Common mistake: ignoring the drain slope, which can cause water to sit in the line and create hygiene issues. Checkpoint: pour a small amount of water into the drain pan to confirm it flows away freely.
3. Connect the tap and route lines: Mount the tap on the counter and route the bundled lines from the tap to the unit. Keep bends gentle and avoid pulling the lines tight. Common mistake: trapping lines behind the unit or against a sharp edge, which can cause leaks later. Checkpoint: trace each line by hand to ensure there are no kinks or pinch points.
4. Turn on water and check for leaks: Open the shut-off valve slowly and inspect all connections under the counter for leaks. Tighten any fitting that weeps, but do not overtighten plastic connections. Common mistake: turning on the water at full pressure immediately, which can stress fittings. Checkpoint: place a dry paper towel under each connection and check again after 10 minutes.
5. Power up and flush the system: Plug the unit into a grounded outlet and allow it to fill. Flush the hot and chilled water lines according to the manual, typically by dispensing several liters and discarding the water. For sparkling, dispense and discard until the water runs clear and carbonation is consistent. Common mistake: skipping the flush, which can leave sanitizer or debris in the lines. Checkpoint: taste the flushed water; it should be neutral with no aftertaste.
6. Verify temperatures and carbonation: Use a thermometer to check the hot water temperature at the tap and compare it with the setpoint. Draw chilled water and check that it is cold. For sparkling, dispense into a glass and observe the carbonation; it should be lively, not flat. Common mistake: testing only the first cup, when the system may not have reached stable operation. Checkpoint: test again after the system has run for 15 minutes to confirm stability.
7. Set up daily operating routine: Train staff to dispense a small amount of water from each function at the start of the day and to check for leaks under the counter. Establish a cleaning schedule for the tap and external surfaces. Common mistake: assuming the system is maintenance-free and neglecting the drain pan. Checkpoint: add a weekly check of the drain pan and ventilation openings to your cleaning rota.

Product facts

Marco FRIIA CS Water System: The Marco FRIIA CS Water System delivers hot water at precise serving temperatures on demand, with no temperature drift during service. This means you can rely on consistent hot water for tea and Americanos even during peak periods, but it also makes correct commissioning essential so the temperature is stable from the first cup.
