Setting the "mid-range" position:
`
Rotate the thermostat knob to the mid position.
Remove the terminal cover by using a large flat
bladed screwdriver to depress the four snap lugs
located in the four top rectangular depressions
on the cover. Holding the thermostat knob in
position turn the terminal cover over and remove
the backing disc from the underside of the cover.
Turn the backing disc over and refit to the knob
ensuring the notch locates with the boss on the
underside of the cover. Refit the terminal cover,
the thermostat will now be locked in the "mid-
range" position.
Setting the "hot" position:
`
Rotate the thermostat knob to mid-way through
the hot graduated range (red graphic). Follow
the procedure detailed above; however in
this case the knob should be held in the "hot"
position previously set. When the terminal cover
has been refitted the thermostat will be locked in
the "hot" position. This position is recommended
when using the heater in conjunction with a
thermostatic blending valve.
Water may drip from the discharge pipe of the
`
pressure relief device - this pipe must be left
open to atmosphere.

WARNING
Do not block or restrict the
`

`
valve fitted.
If water discharges from any

The product stores water at the temperature set
`
on the adjustable thermostat. This can be set to
give temperatures in the range of 10 to 75°C. To
avoid any risk of freezing when the product is not
in use for long periods during the winter months,
do not switch off the electrical supply and set the
thermostat to its minimum position. N.b. this will
not protect other system pipework.
The thermostat can also be locked in either the
`
mid-range or a "hot" (recommended when using
in conjunction with a Thermostatic Blending
Valve) position. To lock the thermostat position,
the instructions given under Section 7 page 12
should be followed. We recommend that this
procedure is carried out by a qualified electrician.
