Description
The Zip Tudor II and Contract II models are SINGLE point-of-use open outlet water heaters.
Being displacement type water heaters the hot water ow 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 3 metres).
Being fully automatic the Tudor II and Contract II 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 overbasin models)
or a Zip approved open outlet vented tap. This type of tting 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.
Overtightening 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 operating temperature range is 35-80°C. To protect the water heater against frost the
temperature control setting may be positioned at ‘ ‘ when a stored water temperature
of 5°C will be maintained. NOTE -the protection does not extend to connecting pipework or
ttings.
The economy setting ‘E’ will maintain the stored water temperature at approximately 60°C.
At the ‘E’ setting the temperature control locates into a set position and slight resistance will
be felt when rotating the temperature control beyond this setting. This is a safety measure to
ensure that higher temperatures are deliberately selected.
Neon Lamp (Tudor II and C3/50 models)
The Neon lamp will glow 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.
Once installed DO NOT remove the cover under any circumstances without rst isolating the
electrical supply to the heater.
