The u1 epitomises cutting-edge design and innovation with its contoured tap and compact under-counter unit. This is our most discreet range and will fit into any environment seamlessly.

The under-counter dispenser is a Dry Chill™ cooler designed to

provide ambient still, chilled and/or carbonated water. All the materials and components are tested during the entire production process in order to satisfy all expectations.

Please Note: Mains Installation Kit & Filters are supplied as extra items according to individual ordering requirement.

When planning and providing for the connection to the
services, always allow for easily accessible service isolator fittings and for the position of an external water filter.

Identify a suitable position for the swan neck faucet. A 33-35mm (max) hole is required.

When positioning to drain over an existing sink bowl, allow for the reach of the swan neck or otherwise the position of any optional drip tray.

Also allow for the height of the swan neck under any
overhanging cupboard/shelf.

Allow for the space needed for forming the required hole. Relate the selected position to the underneath of the counter and check for any obstructions.

Allow sufficient space for fitting the back nut to the faucet stem.

Carefully form the needed hole using the correct type of cutter for the work surface material.
Observe all local occupational health and safety requirements.

Remove the back nut and washer from the faucet and carefully feed the connecting pipe tail and ribbon cable through the hole formed in the work surface. Ensure the sealing O ring is prefitted in the base of the faucet. You may want to apply a thin bead of silicone sealant also.

With the faucet control panel in the right position, carefully refit the back washer and nut. Take care not to over-tighten.

Install the ventilation system using the instructions/templates provided.

Fit optional Drip Tray at this stage (if selected).

Once the ventilation system is installed, position the unit on the ducting as instructed and follow the connection steps  – see Ventillation System Installation Steps

When Borg & Overström undercounter units are installed inside a cabinet or housing, adequate ventilation is recommended to ensure that they operate satisfactorily.

During a cooling cycle it is normal for the unit to produce heat, and the purpose of ventilation is to provide a supply of air that can absorb the generated heat which would otherwise accumulate inside the cabinet or housing, and reduce the cooling performance of the unit.

The amount of heat generated by the cooling cycle depends directly upon the amount of usage – the higher the usage, the more heat produced.

To provide adequate ventilation we recommend that air grilles/vents are fitted as supplied (or vent apertures formed) in the cabinet to allow an airflow as shown below. Normally this should be enough for all situations.

Important: Before making any cuts into the cupboard or kick board, ensure the area to be cut is free from water pipes or electrical cables. There is a risk of serious injury or death if electrical cables are cut, and significant damage to property if a water pipe is cut.

Using the template provided, carefully mark and cut the aperture to the edge of the cabinet.

Situate the Simple-fit ventilation base in place centrally over the aperture. Ensuring that there is a minimum of 30mm air gap to each side.

The S2 appliance must be placed carefully in position on the ventilation base to ensure the chimney is located correctly in the chimney aperture at the rear of the base. After installation the vents at the front of the cabinet and to the sides of the ventilation base must not be obstructed. Any obstructions will adversely affect the airflow to the appliance causing potential for poor performance, over heating or fridge failure.

Locate the machine in a suitable enclosure, ensuring
that the supplied ventilation kit can be installed.

Connect the u1 tap to the water outlet.

Connect the faucet connection harness to the tap control panel membrane.

Install within connection box as supplied.

*Connect the CO2 supply from gas regulator, ensuring
the pressure is set to max 58 PSI (4 bar), and turn on the supply.

Connect the chiller to the water supply and open the mains supply isolation valve.

Connect the unit to the electrical supply and turn on.

After approximately 10 minutes, the compressor and
fan will stop as the chiller has reached its normal operating temperature.

*The carbonator should be purged of air by activating the sparkling water dispense for approximately 20 seconds.

*Isolate the water supply and activate the sparkling
water dispense. When the water system has emptied,
allow gas to be expelled for approximately 5 seconds.
Immediately after this 5 second period restore the water supply and allow the system to refill.

Dispense ambient, still and sparkling water, in turn,
to purge any air from the system. The time to do this
may vary depending on the length of pipe between the
unit and the tap.

The unit should be isolated from the electricity supply before removal of any covers.
Great care must be employed when working with high pressure carbon dioxide, andin no cases should the maximum operating pressure of 58 PSI (4 bar) be exceeded.

NOTE: The soda water flow rate is set to 35ml/sec at a CO2 pressure of 58 PSI (4 bar). To adjust the soda water flow rate follow these steps:

Remove the 3 screws holding the unit lid down and lift the lid away.

Locate the flow control adjuster, this can be found on top of the carbonator can, connected to the central port of the can.

Loosen the lock nut, but do not remove.

Flow can then be adjusted by turning the adjuster screw, anti-clockwise to increase flow and clockwise to restrict flow. After each adjustment the flow rate should be timed.

Once the correct flow rate is achieved reverse steps 1, 2 and 3.

We recommend you check the dimensions of the ProCore Simple-fit Ventilation Kit using the cutting template prior to cutting the base cabinet.
