UNIT HEATER
WARNING
The electrical isolator should only be used in an emergency and should not be
used for closing down the burner, as this switches off the fan prematurely and may damage
the heat exchanger invalidating the warranty and causing a potential fire hazard.
Operating the electrical isolator on a CUH Manual Ignition heater
will also turn off the pilot burner.
4.10 External Controls
Operate the External Controls as installed which may include time switch, room thermostat and manual
switch to ensure that they function correctly. Set the time switch (if fitted) and room thermostat to the
users requirements.
See Sections 2 and 9.
4.11 Handing Over
Ensure that all covers are fitted correctly and all test points are properly sealed before leaving the
appliance.
When the commission is complete explain to the user the controls of the heater including how to
operate the heater and how to turn it off, using the controls fitted on site. Hand over these instructions
to the user.
Ensure that the user is shown and understands the emergency instructions in Section 9 of this book.
