![]() | R290 is a refrigerant-grade propane used on a wide range of commercial refrigeration and air conditioning units. A highly pure propane, it has a low environmental impact and nominal global warming potential (GWP), meaning it possesses no qualities that can destroy the ozone layer. R290 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 R290 can only be maintained and repaired by authorized technicians who are properly trained and certified. |

Installation Requirements
Identify a suitable location for the E4 unit. It should be positioned within 2.0m of suitable services connections. Allow 15cm of free space at the rear for ventilation.
The E4 unit must be installed in accordance with the relevant requirements of:
- The appropriate building regulations by application of either The Building Regulations (England and Wales), The Building Regulations (Scotland) or The Building Regulations (Northern Ireland). In territories other than those listed the local regulations in force must be complied with.
- The Water Supply (Water Fittings) Regulations (England, Wales and Northern Ireland) or The Water Byelaws in Scotland.
The unit must not be installed where it is liable to freeze. If the unit is thought to be frozen it must not be switched on. It should be allowed to thaw and must then be thoroughly inspected to ensure it is undamaged.
Service Requirements

E4 Installation & Water Connection
The use of a Borg & Overström installation kit is highly recommended. All kits have been designed to include all the parts you need to safely and correctly install our dispensers. To ensure you select the correct kit for the model you’re installing, please visit the website or contact our support team.
All installations of water dispensers must include a water block. A water block is conveniently included in every one of our installation kits. If you’re not a using Borg & Overström installation kit, ensure you install a water block – failure to do so will negate any insurance claims for water damage resulting from water dispenser malfunction.
For installation kits and water blocks please see our store here.
NOTE: The water filters on the supply line to the unit needs to be pre-flushed prior to the water connection to the appliance.





Adding Countertop Drainage
If you require drainage to the driptray when the dispenser is used on a countertop. We recommend you use a hole cutter so your drainage tube can be connected to the mains or to a waste kit in the cupboard below.
Dimensions to help you cut the aperture in the correct position are shown below.

CO2 Bottle Installation - Sparkling Version





Sparkling Water Flow Rate - Sparkling Version
NOTE: Sparkling water flow rate factory setting = 2.4L per minute MAX. This may need adjusting
depending on inlet pressure. To do so follow below steps:




Once the correct flow rate is achieved place the cover back on to the unit by sliding it in place and replacing the screws.
Hot Tank Commissioning

Check hot switch is off.



Maintenance & Cleaning
Sanitisation Guide
The product is supplied from the factory in clean condition, but we recommend that a sanitisation procedure is caried out at the point of installation, according to the sanitisation instruction relevant to this model, which can be found in the respective Instruction & Operation Manual.
NOTE: Failure to use sanitising products and processes approved by Borg & Overström will invalidate your warranty.

This operation must only be carried out by trained staff.

A sanitisation procedure is recommended every 6 months.

Turn off incoming mains water

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

Remove the existing filter

Use hand gel and put on protective gloves.

Add 25 ml of Bioguard Internal Sanitising Solution to a clean and empty service filter cartridge.

Connect to filter head.

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

Dispense water using the chilled button until the water appears pink. Repeat with sparkling & ambient water buttons.

Leave the solution inside machine for sanitisation to take effect (minimum 5 minutes) while thoroughly cleaning the dispenser externally. (All maintenance operations must be carried out with the dispenser switched off.)

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

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

Attend to any cosmetic marks as needed. For this we recommend the use of Bioguard External Sanitiser.

Reconnect the power and switch on the dispenser.

When the external cleaning (minimum 5 minutes) is completed, flush the machine using the chilled button with clean water until the dispense water runs clear. Repeat briefly with the ambient and sparkling buttons if present.

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

Remove the service filter. Retain service filter for reuse.

Fit new filter and turn on incoming water supply.

Pre-flush the new filter to waste using the chilled button until the water appears clear and is free of air. Flush through a small amount of water to check all functions.
![]() ![]() | Please note that this sanitisation fluid contains an active caustic/alkaline agent. Always use responsibly and with care remembering that due to its alkaline nature unnecessary concentrated/prolonged contact with any materials, including metals, can cause damage. Always rinse all contact surfaces after use with clean water. | ![]() ![]() | Avoid skin contact and wear protective gloves when handling sanitisation fluids. In the event of any skin contact, flush immediately with clean, cold water. |
Emptying the CO2 Tank




Advanced Troubleshooting
Fault Diagnostics
Problem/Report | Possible Cause | Suggested Action |
---|---|---|
No Water Dispensing | Power supply turned off | Check the power supply has been fitted properly and turned on. |
Water pressure regulator | Check water flow through the regulator. Replace if necessary. | |
Check tap HMI control | Check fault codes. | |
Water isolated from machine | Check water inlet supply. | |
Leak detection in unit triggered | Disconnect the power and water supply, check for leaks. | |
Lock icon not pressed | To dispense from hot, press the lock symbol first then hot shortly after. | |
No Sparkling Water | No CO2 pressure | Check CO2 bottle, regulator and non-return valve. Supply pressure should be 58 psi (4bar), replace as necessary. |
Carbonator tank not filling | Check carbonator probe for possible short circuit to ground. Check for pump timeout, cycle power off & on then purge carbonator. | |
Poor Quality Carbonation | Incorrect CO2 pressure | Check CO2 bottle, regulator and non-return valve. Supply pressure should be 58 psi (4bar), replace as necessary. |
Air in carbonator tank | Refer to installation and water connection section to see how to purge the carbonator tank. | |
Residue in carbonator tank | After prolonged use, a surface film can develop within the carbonator tank. Refer to cleaning and sanitising instructions. | |
Warm Drinks | Insufficient cooling air flow through the fridge | Check that the condenser is not blocked. Check supply to cooling fans. If supply present replace fans. If supply not present move on to the compressor. |
Compressor not running | Check supply to compressor (115/230V AC). Check NTC probe is not faulty. | |
Fridge failure | If compressor & fan are running and there is no cooling contact technical support. | |
Water lying on top edge of lower door panel and/or bottom of cabinet | Overflowing drip tray or waste container | Empty waste container and check drainpipe is not blocked. |
Water lying in bottom of machine | Leak in pipe work and/or filter | Contact your distributor. |
Bleeping noise | Level sensor fitted and waste tank full | Empty waste tank. |
Internal leak detect alarm | Check there is no internal leak. | |
Temperature not hot enough | Mid heating cycle | Unit is not at correct temperature, wait a few minutes before dispensing. |
Power supply turned off | Check the switch is turned on. | |
Water demand too high | See product specification. | |
Element not working | Check and replace as required. | |
Dripping | Heater over heating | Ensure a long dispense is carried out to clear any air gaps. |
Continuous or incorrect dispense | Poorly seated HMI lens | Replace lens assembly. |
Excess water on lens | Ensure you keep lens clean and clear of liquids. |
