Last updated 3 months ago

Sparkling Water Out Plumbing

Insert 4mm x 8mm ID EVA Barrier hosing (sold separately ) into the SPARKLING OUT push in fitting. Attach this 4mm x 8mm ID EVA Barrier Tube to your sparkling water tap

Chilled Still Water Out Plumbing

Insert 4mm x 8mm ID EVA Barrier hosing into the CHILLED OUT push in fitting. Attach this 4mm x 8mm ID EVA Barrier Tube to your chilled still water tap (if using your own tap)

Dispensing Sparkling Water Only

Mains Water Installation

Before connecting your mains water up to the Benchy Sparkling ensure that the sparkling water and cold-water outlets are connected to a tap or plugged and all push in fittings are connected and all hosing is secure.

IMPORTANT: For first time setup, keep the mains water supplying the Benchy Sparkling off until the unit has been connected to all dispensing taps and CO2.

IMPORTANT: In order for the Benchy Sparkling to function correctly and to ensure there are no leaks the mains water pressure must be regulated to no more than 80psi (70psi or less is recommnded). If the mains water pressure is not regulated then the internal float valve can be damaged by high pressure.

Damage to the float valve can cause mains water leaks and is not covered under warranty.

Ensure the tubing is pushed esecurely into eacxh fitting.

CO2 Gas Cylinder and Regulator Installation

Before attaching the regulator to the CO2 cylinder, unscrew the green PRV and replace with the grey PRV. This allows pressures over 60psi to be set without causing the PRV to engage.

IMPORTANT: After you have attached your Benchy Sparkling to your dispensing taps and connected your Gas supply and mains water supply EVA Barrier hosing to the push in fittings on the unit it is important to perform a leak test on the system. Failure to do so could result in your CO2 cylinder emptying faster than expected or water leaks occurring.

Leak Testing

It is essential to perform a pressure (leak) test prior to dispensing any sparkling or cold still water from the Benchy Sparkling.

The Benchy Sparkling need to be pressure tested to a pressure that is at least 1.5 times the pressure that will be used for dispensing. For example, if your dispensing pressure is 70 psi then the pressure test should be conducted at around 100psi.

Pressure Decay Test

  1. Ensure mains water into the Benchy Sparkling is turned off, the regulator adjustment knob is turned fully counter clockwise and the unit is connected too all dispensing taps

  2. Set the CO2 pressure on the regulator to 1.5 times the dispensing pressure by turning the adjustment knob on the regulator clockwise until the correct pressure is reached

  3. Turn the gas cylinder off and leave to sit for a few hours (overnight is preferred). Then check if the pressure on the regulator has decreased from the set pressure

If the pressure has dropped then this indicates that there is a leak in the system. The source of this leak needs to be determined and fixed before proceeding

Bubble (Air-leak) test

  1. Ensure mains water into the Benchy Sparkling is turned off, the regulator adjustment knob is turned fully counter clockwise and the unit is connected too all dispensing taps

  2. Set the pressure on the regulator to 1.5 times the dispensing pressure by turning the adjustment knob on the regulator clockwise

  3. Spray all connections with soapy water and look for the formation of bubbles. This includes all push fit connections and connections between the regulator and CO2 cylinder

If bubbles are formed at any of these connections this indicates a leak which needs to be fixed.

If your tap features a 6.35mm OD fitting then the 4mm x 8mm ID EVA Barrier hosing can be stepped down using a duotight 6.35mm x 8mm reducer () sold separately.

To connect to the KL23917 - use the included 6.35mm joiner to connect to the barbs on the Dual Outlet Tap. Use a short length of included KL11143 - from the joiners. Connect the KL07481 - to the 6.35mm line, then connect the 8mm side of the duotight fitting to the Chilled and the Sparkling 8mm line out.

Please refer to the below

The Benchy Sparkling can also be used to dispense only sparkling water if preferred. To achieve this, simply plug the chilled still water OUT push in fitting with a

Install the included KL17756 onto your mains water supply valve which has a ½ inch thread. Run a length of KL11143 from the diverter valve to the KL42925 - . Install another length of 6.35mm PET Water Line from the inline pressure valve to the Water In on the Benchy Sparkling.

In order for the Benchy Sparkling to operate correctly, the CO2 pressure must be between 10-15psi less than the water pressure. Thus, with the KL42925 - installed, the CO2 pressure must be set to 55-60psi. This will typically provide a good level of carbonation.

If this level of carbonation is too high a KL26918 ) (not included) can be installed on the water line in order to lower the mains pressure from 70psi.

In order to reach good levels of carbonation the included 65psi green PRV (Pressure Relief Valve) on the regulator needs to be swapped for the KL03070

Tightly connect the KL07429 to your CO2 cylinder (or ) and ensure the regulator pressure adjustment knob is turned completely counter clockwise to set the pressure at 0psi. Push KL06224 into the duotight fitting on the regulator and then push this tubing into the Gas Inlet push in fitting on the Benchy Sparkling.
