12 Days Of Christmas Shut Down

1. Panel Heaters

All panel heaters supplied within Cleveland units have an internal thermostatic cutout mechanism to prevent overheating. If the heater stops working, turn it off at its fused spur, check that the fuse is intact, and wait five minutes before switching back on.

2. Downflow Heaters

All downflow heaters supplied within Cleveland units have an internal thermostatic cutout mechanism to prevent overheating. Should a unit stop working it will need to be reset. Instructions on how to do this can be found at the bottom of the page.

3. Water Shut-off Valves

During winter cold weather, to prevent pipe freezes make sure that all incoming water valves are shut off when units are not being used. Draining all remaining water from the internal pipes will stop pipes from freezing.

4. Powering Down/Up

To prevent damage to internal water heaters powering down / up of units should be done as follows

  • Powering down: Turn off power before shutting down water supply.
  • Powering Up: Turn on water supply before turning on power.

5. Keys & Locks

Do you know who the keyholder for the site is?
Do you have spares held off-site with a trusted employee?
If you have had units on site for a long time have the lock mechanisms been greased to prevent freezing?

6. Dehumidifiers

All dehumidifiers supplied within Cleveland drying room units have an internal water collection receptacle. If the dehumidifier leaks water, isolate the dehumidifier unit, locate and empty the water receptacle before powering back on.

7. Toilet Blockages

Clear and double flush through all toilet pans before leaving site. Did you know that the biggest cause of toilet blockages is through the use of paper towels / blue roll?

Restricting the use of these items within toilet blocks will stop costly call-outs to unblock toilet pans.

8. Tank Empties & Refills

Did you know you can pre-book / schedule regular effluent tank empties to avoid any issues with overflowing tanks?

Simply contact the Cleveland Hire Desk to pre-book and schedule empties at your desired intervals based on your usage.

9. Water Heaters 

Water heaters have an internal safety cut-out to prevent damage to the unit’s element. Should this need to be reset, please follow the reset instructions provided here.

Additionally, a water heater should never be turned on at the fuse spur until water is flowing from the tap.

10. Water Supply Pipes

Lagging external water supply pipes including pumps and ICB’s will prevent freezing or consider heat tracing for all external pipework.

11. Refrigerators

If power is going off, or if the site is being left unattended for a while, ensure that fridges are emptied.

12. Generator Servicing

Most generator suppliers, whether Cleveland or another source, specify certain ‘general maintenance’ areas as a customer responsibility such as oil and water.

Overheating Protection Errors & Resets

The heater is equipped with electronic overheat protection. This constantly monitors the heaters temperature. If for any reason this fails, there is a manual thermal cut out and thermal fuse built into the heater.
In the event the heater fails, a fault code will be displayed and flash on the LCD display.

  • ERR 2 – Temperature sensor fault (External)
  • ERR 3 – Temperature sensor fault (Internal)
  • ERR 7 – Motor Fault
  • ERR 8 – Motor Slow
  • ERR 9 – Overheat

If any fault occurs the heater will be switched off and will not work. To reset the fault code, use the following steps:

  1. Ensure the heater is in standby mode
  2. Press and hold all 4 buttons on the heater
  3. The heater will now show ‘test’. The heater will perform a self-test to check everything is ok.

If the fault is still present, the fault will not clear, and the heater will not operate. The fault must be rectified before the heater can be used again.

Reset Instructions for Hyco Undersink Water Heaters

  • Discount electricity supply before maintenance.
  • A re-settable safety thermal cut-out switches off the element in the event of the unit over-heating. The thermal cut-out may trip occasionally in normal use. If this happens the heater will not heat water and the element light will not come on.
  • The thermal cut-out is located underneath the unit behind the grey access plate.
  • Depending on the mounting position of the unit, you may need to uninstall the unit for ease of access to the cutout. In these cases, disconnect electricity supply and unscrew flexible hose connectors.
  • Drain water from heater and locate grey access plate.
  • Remove the cover retaining screws and gently prise cover off. The thermal cut-out will be visible. To reset the cutout, depress the button in the centre of the device. If the device has tripped, reduce the thermostat setting if possible.
  • If the device trips repeatedly with a low thermostat setting, contact Hyco Technical Department on 01924 225200.
    To access the element or anode, unscrew the bolts holding the flange in position. The element and anode can then be removed. Reverse to re-fit.
