If the drum thermometer is suspected to be reading inaccurately, it can be
checked with the use of a calibrated digital thermometer and a water ice
mix at 0° C.
To check the drum thermometer accuracy

2. Open the cabinet door and cut the
cable ties to detatch the drum
thermometer bulb from the port hole
on the cabinet ceiling.
3. Unplug and remove the sign assembly (if fitted) or remove the sign
replacement panel.
4. Unscrew and remove the control panel cover.
5. Unscrew and remove the control panel (with drum thermometer attached).
6. Unclip and detatch the drum thermometer from the control panel, and
withdrawl the bulb and cable through the cabinet and control panel.
7. Reverse the steps to fit replacement drum thermometer. When refitting, use
putty to seal around the area where the bulb cable enters the cabinet.
