Thank you for choosing a quality Redring product from Applied
Energy Products Limited, Peterborough, U.K
General Product Description
The “SB Professional Range” are wall mounted, self-calibrating and self-filling boiling wa
ter heaters.
Theycan be used for making cups of tea orcoffee and even soupsand hot snacks.
A special condenser traps steam and returns droplets to the tank, minimising waste and saving
energy.
The water temperature is set at approximately95°C (dependent on unit volume) and automatically
maintained bythe unit.
Pulling the front lever forward dispenses hot water.
11
ImportantNotes
The heater level detection system uses two protective resistors to earth, this results in an insulation
resistance (IR) of 0.5M Ω, and asa consequence the equipment would appear to faila routine
Portable Appliance Test (PAT).
This is onlyrelevant if the unit is fitted with a standard 13A plug, however, this product is not to be
classed as a portable appliance, and as detailed on page 3, it is instructed that the unit is to be wired
to a means for disconnecting the fixed wiring in all poles in accordance with the wiring rules
(eg. 13A fused double pole isolating switch).
In the unlikelyevent that the unit is fitted incorrectly, the recommendation is if test iscarried out with
water in the tankthe IR reading will be 0.5MΩ. Ifthis becomes an issue to the PAT engineer, switch
off the power and drain the tankthrough the tap prior to connection test.
PATtest is not acase ofpass/fail. IfPATrecords negative then thisis not a failure. It highlights the
possibility ofa failure and then the unit should undergo further investigation.
With regards to BS EN60335-1 Clause 16 earth leakage (not IR) can be 0.7A per kW= 1.8mA.
Test at 254V (6%above nominal) / 1.8Ma =141k Ω so reading of0.5MΩ is acceptable.

If in anydoubt, advice and assistanceshould be sought from a qualified plumber
and/or electrician.
•
Installation and wiring must conformto the current BS.7671 (IEE Wiring Regulations)
and the Water Fittings Regulations. Local regulations mayapplyin other countries.
•The steamvent connection MUST BE MADE, as requiredin these instructions.
•Ameans fordisconnection in all poles must be incorporated inthe fixed wiring in
accordance with the wiring rules.
•Check that the mains supplymatches the electrical rating on the product.
The rating plate is located on the bottom edge of the unit.
•THIS APPLIANCE, AND ALL METAL PIPEWORK CONNECTED TO IT, MUSTBE EARTHED.
•This appliance must be connectedtoa TN-Systemel
ectrical power supply.
This has a common earth-point. It is not suitable for an IT-System electrical powersupply
as this has an isolated earth-point.
Please note: this is applicable for some Europeaninstallations.
•Frost Protection: This appliance should be located where the ambient air temperature is
between 5°C and 50°C.
If the temperature mayfall below5°Cwhenthe appliance is not in use, do not turn off the
appliance electrically.
This safeguard does NOT offer protection to the connecting pipe work andfittings.
The unit should not be operated if freezingis suspected.
Allowthe unit to thawcompletely.
•This unit must not be cleaned by, or installed in anarea cleaned by, a waterjet.
•If you have anyqueries about installing this product or after it has been installed, please
contact the Applied Energy CustomerService Helpline on 0844 372 7766.
Customers outside the U.K. should contact their local Redringdistributor.
What the installer will need
•A meansfor disconnecti
ngthe fixed wiring in all poles in accordance with the wiring rules
(eg. 13A fused double pole isolating switch).
•Suitable length of1.0mm² 3-Core multi-strand PVC insulated mains cable that complies with
BS.6500.
•Suitable lengthsofØ15mm copper pipe.

Where to locatethe unit
•We recommend that the unit is installed on a suitablewall, at shoulder height and over a sink.
•Adjacent to the means for disconnecting the fixed wiring in all poles in accordance with the wiring
rules (ie: 13A fused double pole isolating switch).
•Available mains cold water supplyand drainage facility.
•DO NOTinstall the unit within reach of a person using a bath or shower.
•This unit must not be installed in an area cleaned bya water jet.
•DO NOTobstruct the ventilation channels on the top ofthe cover plate.
Installing the water supplyand steam vent pipes
The unit must be connected to cold, mains fed, drinking water only.

•
The steam vent connection must be taken directlyto the sink below, ifthere is one,
or via a tun
dish to a suitable drain.
If a sinkis used it must be able to withstand boiling water and have an overflowconnection.
Installing themains supply
If a mainssupply is not alreadyavailable.

Maintenance/ DescalingProcess
ToDrain the unit
•Turn off the water and electricitypowersupplies.
•Turn on the tap on the front of the unit to drain the tank.
•Unscrewand remove the tap and remove 4 fixing screws on outercover.
•Shield the electronic controller from possible water damage.
•Carefullyremove the drain plug from the bottom ofthe tank and drain.
WARNING: Beware of splashing water as it maybe near boilingpoint.
Descaling
If scale comes out with the hot water then the unit mayneed to be descaled.
As with all waterheaters scale will buildinside the tank.
Howquicklythis build up occurs will depend on the hardness of the water andthe frequency
ofuse.

•Mix2 teaspoons (approximately10ml) food grade citric acid into a cup of water.
•Feed citric acid through tap hole (eitherbyfunnel or placing tap half wayon the thread, turning
upside down with the tap lever permanentlyopen).
•Tighten tap, leaving outside cover off.
•Turn power on, unit will cycle and fill. Allowunit to boil for 10 minutes then drain.
•Turn power off.
•Drain unit and remove tap.
•Replace outside cover.
•Replace tap, turn power on.
•Wait until unit has filled with water – drain once again from tap, allowunit to refill.
•Unit is readyfor use.
Cleaning:
•Before cleaning, switch off the electricityat the isolating switch.
•It is recommended that the unit surfacesare cleaned with a soft cloth.
•Do not use abrasive or solvent cleaning fluids.

Operating Instructions
Initial Operating Instructions
•Make sure the water is turned on prior to mains electricitysupply.
•Check all connections forwater leaks.
•Turn on the power and wait approximately20 minutes before using.
Priming theunit
When the power is turned on for the first time the unit will automaticallyprime itself, covering the
heating element.
The heating element will then switch ON and boil that amount ofwater(this will take 10-15 minutes)
starting the automatic Heat and Refill process until the tank is full.
The unit then goes into maintenance mode, keeping the water at the required temperature.
Th
e unit should be switched offat the mains if the water is not required for a long period oftime
(eg: at weekends, holidays etc).
Pleasenote
•The unit can take severalminutes to reach the required temperature, dependingon usage and
tank capacity.
•When first installed, it is recommended that the initial tank of boiling water is fully drawn off and
discarded. Allowthe tankto re-fill before using the unit.
POWER light
When the unit ison, the POWER light will be illuminated.
SafetyFeatures
•The boiling water unit is fitted with a MANUAL RESETSAFETY DEVICE, which operatesin a
BOIL DRY situation, and a MANUAL RESET THERMOSTAT, for detecting excessive steam in
the event of electronic controller failure or water solenoid valve failure.
•
Unless you are a qualified engineer DO NOTATTEMPT to repair this unit yourself.
