R600 Safety Message

R600a is a refrigerant-grade isobutane used on a wide range of commercial refrigeration and air conditioning units. A highly pure isobutane, it has a low environmental impact and nominal global warming potential (GWP), meaning it possesses no qualities that can destroy the ozone layer. R600a also is the preferred hydrocarbon alternative of the Environmental Protection Agency (EPA), substituting more harmful fluorocarbon refrigerants like R22, R134a, R404a and R502. Units with R600a can only be maintained and repaired by authorized technicians who are properly trained and certified.

Section 1: Installing a floorstanding dispenser

1

This operation must only be carried out by trained staff.

2

Position the unit in the desired location, ideally against a wall and away from areas of egress. Allow 150mm of clearance at the rear of the unit for ventilation.

3

Check the unit is level. Adjust the feet of the base cabinet if needed.

4

Fix the filter head to the filter bracket inside the base cabinet using the pre-drilled holes. Ensure there is sufficient space below to install the filter.

5

Install a water block after the mains water supply. Failing to do so will invalidate the warranty for that unit. Connect the mains supply to the water-in bulkhead connector at the bottom of the unit.

6

If waste is required, remove the drip tray and remove the bung.

7

Remove the top and front panels to gain access to the waste spigot.

8

If you have a waste container, place it within the base cabinet. Connect the drainage tubing into the top of the waste water container. And connect the other end to the spigot on the back of the front panel. If using mains waste, connect the drainage tubing from the waste spigot to the mains waste.

9

Refit the front and top panel.

10

Remove the pipe from the rear bulkhead connector and fit it to the outlet of the filter head.

11

Using the piping from your install kit, connect the inlet option of the filter head to the internal side of the water-in bulkhead connector. Use locking clips on each connection for security.

12

If you have a sparkling model, complete the CO2 installation section below before moving on to the next step.

13

Turn on the water supply.

14

Connect the unit to the electricity supply. Do not turn on any of the rear switches yet. You should hear the direct chill system filling up.

15

For sparkling models, purge the air from the carbonator by pressing and holding the sparkling water dispense icon for 10 seconds. Then turn on the carbonation switch on the rear of the unit.

16

For hot water models we must commission the hot tank. Press and release the 'Hot' icon to unlock, then press and hold the 'Hot' icon to start filling the hot tank. Continue filling until water flows from the outlet.

17

Press and hold the 'Chilled' icon until you see water dispensing from the outlet.

18

You can now turn on the hot switch and cold switch on the back of the dispenser. The chilling system and hot tank is now fully active.
Please note, CSH units may not have a cold switch.

19

Allow the dispenser to stand for 1 hour for the initial chilling/heating process to complete.

20

Flush water through each dispense option by pressing the dispense icons until water is dispensed. Ensure everything functions correctly.

21

We recommend that the unit undergoes a sanitisation procedure prior to first use. You can follow the instructions below. Your unit is now ready for use.

CO2 bottle installation - sparkling models only

1

This operation must only be carried out by trained staff.

2

Unpack the CO2 Regulator and fit elbow fitting to spigot outlet.

3

Make sure the regulator is off by twisting the top knob anti-clockwise before attaching to the CO2 bottle. Do not overtwist.

4

Attach the regulator to the disposable CO2 bottle, ensuring the small pressure relief vent in the stem is facing away from you or anyone else. Hand tighten securely.

5

Connect the assembled CO2 bottle and regulator to the CO2 pipe inside the base cabinet. Use locking clips on each connection for security.

6

Stand the cylinder upright in the base cabinet.

7

Set the CO₂ pressure on the gauge by manually turning the top knob until the gauge reads 3.5 - 4 bar (58 PSI). Do not exceed 4 bar pressure.

Maintenance & cleaning

Sanitisation guide

The product is supplied from the factory in clean condition, but we recommend that a sanitisation procedure is carried out at the point of installation, according to the sanitisation instruction below. We recommend repeating the sanitisation every 6 months.

Failure to use sanitising materials and processes approved and/or recommended by Borg & Overström could invalidate your warranty.
Contact us for more information

You will need

  • Measuring jug
  • Protective gloves
  • Hydrogen Peroxide (H202 3%) food safe sanitising solution
  • Service filter cartridge
  • Sanitising wipes
  • Water filter

1

This operation must only be carried out by trained staff.

2

A sanitisation procedure is recommended every 6 months.

3

Turn off incoming mains water.

4

Briefly press chilled dispense button to release internal water pressure from the machine.

5

Remove the existing filter.

6

Use hand gel and put on protective gloves.

7

Add 25 ml (approx 1 US fl oz) of Hydrogen Peroxide (H2O2 3%) sanitising solution to a clean and empty service filter cartridge.

8

Connect to filter head.

9

Turn on incoming water, allow the service filter cartridge to fill.

10

Dispense water using the chilled button. Repeat with sparkling & ambient water buttons. Do not dispense water through the hot dispense option.

11

Leave the solution inside machine for sanitisation to take effect (minimum 5 minutes) while thoroughly cleaning the dispenser externally. Turn off the dispenser to allow cleaning of the control panel.

12

Pay particular attention to the dispense faucet and the push button controls. For this use an External Sanitiser and Sanitising Wipes. 

13

Clean the drip tray. If a Waste Overflow System is fitted, empty this and flush through with a small amount of sanitisation fluid if needed.

14

Wipe any cosmetic marks as needed. For this we recommend the use of warm soapy water.

15

Reconnect the power and switch on the dispenser.

16

When the external cleaning is complete, flush 10L (approx 4 1/4 US Pt) of water through each dispense option (Chilled, Sparkling, Ambient).

17

Turn off water and briefly press chilled dispense button to release internal water pressure from the machine.

18

Remove the service filter. Retain service filter for reuse.

19

Fit new filter and turn on incoming water supply.

20

Pre-flush the new filter to waste using the chilled button until 5L (approx 2 US pts) of water has flushed through. Repeat this through all dispense options. Your dispenser is now ready to use.

Care and maintenance of dispenser finish

The finishes are typically low-maintenance and retain their look with minimal effort. However regular cleaning and maintenance will ensure longevity and aesthetic appearance.

The appliance should have the lens cleaned once a week minimum using screen cleaner – ensure unit is off during cleaning.

For best results polish the dispenser with a soft cloth as necessary, as soon as signs of dirt or smudging appear. Weekly cleaning with damp cloth using mild soap and water is recommended to maintain shine and remove fingerprints. Dry and polish with a soft cloth.

WARNING: Improper use of cleaners and sterilizers or exposure to strong chemicals can cause corrosion, staining and discolouration. Avoid abrasive or harsh cleaning agents that can damage the finish.

Please note that surface contamination and the surrounding environment can accelerate staining and discolouration e.g. marine environments where salt is present or places with high humidity.
