INSTALLATION AND USER INSTRUCTIONS - RAM1T
Section A — Installation
To remove the cover gently prise off the control
knob and then undo the small cross-headed type
screw. Now pull the cover away from the
backplate. To replace, carry out the reverse
procedure. Adequate space has been allowed for
the connecting cables. A special cable gland is
provided at the base of the housing for securing
the cable.
When used with factory insulated hot water
cylinders, sufficient insulation must be removed
to allow the base of the thermostat to be in
contact with the cylinder wall.
The RAM1T should be mounted approx. one third
of the way up from the bottom of the cylinder and
on the opposite side to the heating coil. Each
thermostat is supplied complete with a metal
spring band, which assures a good clamping.
