30/60-Litre - Ventilation Grill Installation

When Borg & Overström u1 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 the ventilation is to provide a supply of air that can absorb the generated heat which otherwise will 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.
The air grilles fitted (or vent apertures formed) should each have a ventilation area equal to or greater than 25000mm2 and the air circulation path inside the cabinet/housing must be unobstructed. (eg: a vent grille with an overall size of 250mm x 100mm).

It is recommended that an inlet vent grille is set into the plinth with a corresponding vent grille in the base of the cabinet behind the undercounter unit to allow the air to flow past the condenser. An exhaust vent grille is

also required at the top if the cabinet. It is recommended either behind the tap in the work surface or at the side of the cabinet for a more unobtrusive appearance should this area be available.

8-20-30-Litre-CO2-Bottle-Installation

It will be necessary to leave the machine for up to 1 hour for sparkling water to develop, by absorbing the CO2.

30/60-Litre - Refillable CO2 Bottle Installation

NOTE:

  • Before connecting the CO2 bottle ensure the gas being used is food certified.
  • Do not lay the CO2 bottle on its side whilst attaching the pressure reducer, make sure it is always in an upright position when carrying out this task.
  • Always ensure the reducer’s working pressure is higher than the cylinders max pressure.
  • Do not place hands or any other part of the body near the gas as this may cause freeze burns.
  • A small amount of gas leakage during set up/replacement is normal.
  1. Connect the assembled CO2 bottle and regulator to the CO2 inlet on the rear panel (60L) using a 6mm pipe or side panel (30L) using a ¼” pipe (see Fig1)
  2. In instances where a refillable CO2 bottle is being used screw the pressure reducer on to the gas bottle with a spanner (28mm). If however a singleuse gas bottle is in operation, screw the reducer on to the bottle by hand.
  3. If using a refillable gas bottle open it by turning the upper hand grip counterclockwise (item1- fig 2).
  4. Ensure the CO2 bottle is securely connected to the dispenser using the 1/4” plastic tube.
  5. Insert one end of the tube into the quick fit coupling at the rear or side of the machine, and the other connected to the reducer of the gas bottle.
  6. Open the gas bottle by turning the upper hand grip counter-clockwise (item1- fig 2).
  7. Turn the black handle of the pressure reducer clockwise (turning towards the + sign) (item 2- fig 2).
  8. Check that any connection points are free of leaks using soapy water.

Adjusting Sparkling Water
By adjusting the pressure reducer it is possible to increase or decrease the amount the amount of CO2 present in the water; the optimal recommended values range from 2 – 5 bar. A higher pressure will increase the amount of carbonation in the water, with a lower pressure producing ‘slightly sparkling’ water. CO2 pressure must be set at +0.5Bar> incoming water pressure.

Replacing a Refillable CO2 Tank

  1. Detach the CO2 bottle from any supporting chains or belts.
  2. Close the valve at the top of the bottle by turning it clockwise until completely locked (item1- fig 2).
  3. Close the pressure reducer by turning the knob anticlockwise (item2- fig 2).
  4. Remove the CO2 pipe from the pressure reducer, and detach the other end from the dispenser.
  5. Screw the adapter (optional) for the external CO2 bottle to the new pressure reducer and tighten it firmly.
  6. Connect one end of the new CO2 pipe to the pressure reducer and the other to the appropriate connection point on the dispenser (see 30/60 Litre Major Components).
  7. Screw the ring nut of the adapter assembled on the pressure reducer to the CO2 bottle.
  8. Open the valve at the top of the new CO2 bottle.
  9. Reattach any chains or belts removed from the bottle and return it to its normal position.

6. After defrosting shut off the water supply, the CO2 gas, and remove

the power plug.
7. Locate a rubber tube approximately 2m long and a large container.
8. Insert one end of the tube into the bottom of the ice tank and siphon the water through the tube letting it flow in to the container.
9. Ensure the ice tank is completely emptied.

NOTE: Do not remove water from the ice tank by tilting the machine. Water could spill from the tank and cause damage to electrical components within the machine.
