General product description
•
The Zip Tudor models are SINGLE point-of-use open outlet water heaters. Being
displacement type water heaters the hot water flow is controlled by the rate at
which cold water enters the vessel. They can be connected either to the cold
water main or fed from an overhead cold water cistern (minimum head 3m).
•
Being fully automatic the Zip Tudor may be left switched on under the control
of the thermostat, however
WARNING
This means that the unit remains
potentially ‘LIVE’ when the selector is set to ‘0’. The unit can only be switched off
(isolated) by operating the double pole isolating switch to isolate the heater unit
from the power supply.
•
The stored hot water is delivered from an open outlet spout (supplied with over-
basin models) or a Zip approved open outlet vented tap. This type of fitting is
permanently open to the atmosphere which allows the expansion of water, (that
occurs during the heating cycle), to be safely discharged.
•
During the heating cycle, drips will form and fall from the delivery spout or tap
and these will cease when the cycle has been completed and the stored water
temperature has reached the level set by the user. The higher the temperature
selected the greater the rate of expansion. Over-tightening of the inlet water
control valve or tap will not prevent the drips that occur, but may cause damage
to the valve or tap.

Temperature control
•
The temperature control enables an operating temperature up to 75°C to be
selected. To protect the water heater against frost the temperature control
setting may be positioned at when a stored water temperature of 9°C will be
maintained.
Note
this protection does not extend to connecting pipework or fittings.
The economy setting
e
will maintain the most economical stored water
temperature at approximately 41°C for models T4OB5, T4UB5 or 35°C for models
T4OB10, T4UB10.
Lime-scale formation and heat loss are minimised at the economy
e
setting, however
the operating temperature may be increased as required where higher temperature
hot water or a greater volume of mixed water is required. Setting
III
= 75°C.
Neon lamp
•
The Neon lamp will illuminate while the elements are in operation but will
extinguish when the chosen temperature has been reached.
CAUTION
The
unit will remain ‘LIVE’ when the neon lamp does not glow.

WARNING
Once installed DO NOT remove the cover under any
circumstances without first isolating the electrical supply to the heater.
