Installation Instructions
1. Requirements of the Installer
All installation work for this immersion heater kit must be carried out by an individual with the relevant
qualifications and experiences to work with electrical systems and who is registered with an electrical regulatory
body such as NICEIC, and should be compliant to:
• BS 7671:2008 IEE Wiring Regulations 17th Edition.
• BS EN 806 all parts.
• BS EN 60335-2-74, IEC 60335-2-74.
• Building Regulation Part G.
• Building Standards (Scotland) Regulations.
• Water Regulations.
• Health and Safety and Work Act 1974.
• Local Byelaws.
And any complementing or superseding documentation.
Adveco Limited accept no responsibility for failure to comply with the above or with safe working practices.
2. Location
For GSM module responsiveness, it is recommended that the control panel should be sited in an above ground
area with good signal reception . Basement installations may require a remote antenna (not included).
The control panel should be mounted at an accessible height on a wall adjacent to the water heater. The wall
should be strong enough to hold the panel and constructed of a suitable material to accommodate the panel
fixings. Should the control panel be installed away from the water heater, additional isolators must be included
near the heater and its components.
Cable connections for all panels enter through the floor of the enclosure and require 100mm of exterior
clearance. All panel dimensions are included in the technical details on pages 7-9 and should be consulted prior
to installation.
The EB0025 features a removable front panel and is suited for installation within cupboards or tight spaces. A
minimum frontal clearance of 300mm is recommended for access.
The EB0028 and EB0030 models feature a hinged front panel. A frontal clearance of no less than 500mm must
be present in order to open the panel door.

EB0025-EB0028-EB0030 Control Panel - Installation and maintenance manual

• Remove the back panel and its mounted components from the enclosure, resulting in an empty box in
order to prevent accidental damage to the components. Mark out and drill the necessary number of
holes for glands on the floor of the panel. One gland is required for each cable feeding into the panel.
Gland sizes must be correct for the cable they will accommodate.
• Mark out the mounting location on the wall using the supplied brackets. Drill and plug the wall, then
reaffix the back panel to the box and mount the complete assembly. Ensure the box is properly
assembled and securely fixed to the wall.
• A 400V rotary isolator should be installed feeding the control panel to provide means for safe isolation
of the system.
• Cable sizes should be dictated by the electrical load of each component. The terminals within the
control panel are of sufficient size to accommodate the largest cables that may be required.
• All cables must have correctly sized ferrules on the ends. A double ferrule must be used when two
cables are used in one connection.
• All cable glands must provide mechanical protection against pull-out. Within the box the cable insulation
should be cut back to near the gland.
• Unused heat recovery connections should be left empty.
• No additional link wires are required. All needed links are pre-installed.
• Following installation, the panel should be tested to and meet the requirements of NICEIC.

EB0025-EB0028-EB0030 Control Panel - Installation and maintenance manual

Maintenance Instructions
At minimum, the control panel should be checked annually by a qualified engineer. The unit must be fully
isolated from the mains electricity supply prior to any inspection or maintenance work being carried out. The
maintenance procedure should include at least the following checks:
• Visually inspect the interior of the panel for signs of overheating or distress. Any visible dust and dirt
should be removed with careful use of compressed air only.
• Press the test buttons of all contactors to ensure free travel.
• Check the tightness of every terminal connection within the control panel, including building cable
connections.
• With the panel still open, turn on the isolator and return power to the system. Warning: 400V/3ph
power will now be live within the panel. Exercise suitable caution.
• Confirm that the lead heat source is still operational.
• Simulate a fault within the lead heat source. For an electrical unit, trip the circuit breaker supplying the
primary heater. For a gas appliance, put the water heater in to fault.
• Confirm that a fault notification has been received from the GSM module. This can be done by checking
with the manager of the store. Fault messages may take several minutes to arrive by email.
• Check the settings and operation of all thermostats within the system.
• Isolate the system and close the panel door.
• Check the time and programme of the programmable clock (if installed). The clock controls the
destratification pump which should run no less frequently than twice per week, for two hours per cycle.
