PLUG N GLOW INSTALLATION GUIDE

• Congratulations on choosing Plug n Glow 2 – the latest innovation from Advance Appliances.
• Plug n Glow is manufactured in the UK and is a versatile mini electric flow boiler. Let’s get the important stuff out of the way first. It can be installed vertically only and not horizontally and must be orientated as shown below. If it isn’t, the heater pod may burn out. We can tell if the heater pod has burnt out and the warranty will not apply, so please be careful.
• In addition, when it is installed you must be absolutely sure that the pod is full of water before switching on otherwise – no warranty – so once again – please be careful.

DESCRIPTION AND OPERATION

• Plug n Glow is a 2.7kw electric flow boiler with a two year guarantee. It is fitted with a 13amp plug which is sufficient to drive the boiler and a heating circulator pump rated up to 300 watts.
• It can be used in so many ways that we have devoted a section to applications. There are more options – the applications refer to the most common usage.
• First of all it can be programmed – Plug n Glow can be timed to come on and off twice a day in the week, at weekends or both (see page 9) and you can control the temperature on board using the calibrations on the dial (SWITCH “INT” and dial in temperature) or off board with, say a room thermostat, cylinder thermostat, pipe thermostat, flow switch or an outside frost thermostat (SWITCH “EXT” and set your off board thermostat to required temperature).
• The off board thermostat can be connected to the PCB “CONTROL” connection. It must be ZERO VOLTAGE. It is just a switch, of course, so anything you want to use to switch it can be used as long as there is some temperature control. For example if a pump goes live and the Plug n Glow is being used as a boost it can be switched via a relay.
• The temperature control dial is switched off once an external thermostat is used and the switch is in the EXTERNAL position.

IMPORTANT NOTE

• When the switch is set to INTERNAL, (INT) operation, controlled by the adjustable temperature dial and the timer – a pump MUST be connected otherwise the unit will burn out.
• When the switch is set to EXTERNAL operation, the unit will only come on when the timer and the connected external “switch” via “CONTROL” connection on PCB are calling for heat..
• The external “switch” must be ZERO VOLTAGE and wired to the two terminals marked CONTROL in the Plug N Glow. The external switch could be a thermostat, a light, a pump etc. Please note if it is a light or a pump you must use a relay to make sure no voltage goes into the board.
• So, if it is being operated by a pump for example the timer can be set on continuous (press ‘over-ride’) as demand is only made when the pump comes on.
• The same goes for a thermostat operation, however if this is in a separate heating system such as a conservatory you may wish to set the timer appropriately.

THERE MUST ALWAYS BE PUMPED CIRCULATION DURING DEMAND PERIODS.

• Also, once the unit is plugged in and there is demand the PUMP terminal on the PCB will be live. A pump can be connected for heating circuits, secondary hot water loops etc. Use proprietary circulators as you would in normal operation. Look at APPLICATIONS for ideas in using a pump.
• Please note the Plug n Glow only operates on fully pumped sealed systems. It will not work on gravity.
• It has two levels of safety to protect against overheat.

INSTALLING

• Please pay attention to orientation on page two. Please fix securely to a wall with screws and plugs appropriate to bear a load of 1kg.
• It can be located anywhere appropriate inside a building in frost free conditions (unless being used with a frost thermostat) – It should be near a mains socket outlet and at a height and position where it can be accessed easily. If it is an open vented circuit it should be at least 500mm below the water line in the feed tank.
• Do not install in an enclosure without sufficient ventilation and/or exposed to moisture.
• To access connections remove the holding screw and lift off the cover. Remove plugs/wires etc as appropriate. Any pump or thermostat connections can now be made routing cables through the gland nuts fitted. The PCB is clearly marked PUMP and CONTROL.
• Reconnect the wires to the PCB and replace the cover. The pipe connections are 22mm. Use 22mm compression fittings to connect the unit to the circuit.
• This is an important bit – make sure that the circuit is full of water before proceeding. Plug n Glow is suitable for pressures up to 3bar. A sealed circuit needs an air vent at the top of the circuit as well as any vents that may be on radiators etc as it will be essential to expel all air.
• A good idea is to connect the pump in the circuit remotely and run it before you run the heater to eliminate air pockets. The pump has a one minute over-run to extend the life of the heater.
• Once you are completely satisfied that the circuit has no air then you can programme the Plug n Glow and plug in and switch on. If you decide to hard wire use a 13 amp switched spur, make sure any connections are accessible in case the unit needs to be switched off quickly.
• Fill in the commissioning document on page 14 and leave it with these instructions at the customer’s house.

IMPORTANT NOTE
If you are using Plug N Glow to add power to an existing system and want to switch it on with a pump please use a relay on the pump to switch”CONTROL” on/off. This ensures that it is a ZERO VOLTAGE switch. There will be no need to use the pump connections or add another pump.

MAINTENANCE

• Plug n Glow requires no maintenance. However, it must be installed inside a building, and unless you are using it with a frost thermostat (in a greenhouse for example) it should be in a frost free environment. Always use a proprietary inhibitor in heating circuits and if the circuit is drained always replenish the inhibitor to correct dosage.
• There are no user serviceable parts, however in case of pod or PCB failure Advance Appliances can provide spare parts. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.
• The red LED may flash at times during high temperature applications. This is normal and it re-sets three times automatically. If it remains flashing after the re-set please re-boot by switching off the power, waiting 10 seconds and switching back on.

WARRANTY

• We will guarantee trouble free use for two years provided it is installed and operated correctly, is free of air and you keep the commissioning document and your original receipt or invoice.
• If it fails in service due to a manufacturing defect we will repair or exchange it like for like. We cannot be held responsible for other costs. If for example it is used in a place which is not frequented for long periods the system should be drained down. Use common sense – we are understanding, having built our business on trust and quality – we expect our customers to do their best to mitigate loss. 4

APPLICATIONS

• This is the fun bit – Plug n Glow is a great innovation and we have come up with the following ideas and applications. Bear in mind that the EXTERNAL (EXT) button will give you the option of switching it on and off with any switch – for example (using a contactor/relay to achieve VOLTAGE FREE switching) it could be connected so that a pump in a gas central heating system is the switch – if the pump is live it can switch Plug n Glow on when there is demand on the heating system. Or – using a contactor/relay again – a home office heating system could be activated by turning the light on as long as the circuit has a room thermostat incorporated. Or again – for heat pump defrost using off board heat pump controls.
• You can incorporate more than one, just link them in series but please use individual power points – not power extension blocks.
