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.
