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.

Installation

Requirements

• Before starting installation the WARNINGS page 3 and CAUTIONS page 5   should be read and fully understood.
• It is recommended that the piping and water connection is carried out by a qualified plumber.
• Thoroughly flush the water supply pipes before installation to remove any water borne debris.
• The electrical installation including earthing and cross bonding should comply with current IEE regulations and any Local Authority requirements.
• Zip Tudor water heaters must be installed according to the specification on the rating plate and the technical specifications (see page 8).
• Take care to protect the wiring from damage during installation and ensure that any uninsulated wiring is not directly accessible after installation.
• For maintenance work an isolating valve should be installed in the water supply line to the heater.
• A minimum clearance of 270mm is required underneath the over-basin heater units and above the under-basin units to allow for the removal of the element plate assembly and for servicing purposes.
• When locating the heater, consideration should be given to the safe and visible disposal of any water resulting from leaks and seepage.

Wall Mounting

• The unit will be supported Fig. 1 by being hung on a bracket fixed to a support wall, using the fixings provided, as shown in Fig.1

• Therefore it is important to ensure that the wall is strong and solid enough to fully support the unit when the tank is full.

• It is important to ensure when drilling the wall, that the selected position avoids any pipe work or electrical cabling. To mount the heater, the bracket ‘hooks’ locate into the slots provided in the back of the unit, allowing the unit to hang flat against the wall.

Note It is not necessary to remove the casing to mount the water heater on the wall bracket.

Over-basin Installation

• The inlet control valve supplied incorporates compression fittings suitable for fitting between 15mm copper piping (water supply) and the inlet connection (coloured blue) situated on the water heater.
• Fit the control valve to the cold water supply ensuring that the water will flow in the direction of the arrow indicated on the side of the control valve (Fig.2).
• Do not over tighten the compression joints but ensure that they are leak free.

Under-basin Installation

• Connect the hose from (A) on the tap body to the mains cold water supply.
• Connect the hose from (B) on the tap body to the cold water supply to the heater.
• Connect the hose from (C) on the tap body to the hot water output on the heater.
• Fill the heater tank before turning the power on.
• Turn on the water supply and check for leaks.
• Open both hot & cold taps until water freely flows from the tap spout.
• Turn on the heater and allow it to heat up.

Note
When installing under-basin models it is
recommended that fibre washers are used on both inlet and outlet connections to ensure a watertight seal.

Electrical installation

WARNING Switch off the mains electrical supply before carrying out any work involving a live circuit. 230V AC supply only, this appliance must be earthed.
Before starting installation the WARNINGS page 3, and CAUTIONS page 5, should be read and fully understood. It is recommended that the electrical installation is carried out by a qualified electrician.

Pre-wired cable
The Tudor models all come pre-wired with a 1 metre length of cable.
If in the lifetime of the unit the cable is damaged or a greater length of cable is required then to replace the supply cable, refer to the following ‘Cable installation/replacement’ instructions below.

Cable installation / replacement

• First remove the temperature adjustment selector switch and release the screw located beneath.
• Unscrew the four cover screws, two on the top and two on the bottom of the unit, this will then allow the outer cover to be removed.
• The supply cable conductors must have a nominal cross section of not less than 1.5mm².
• The supply cable enters the casing through a cable clamp located in the rear casing cover.
• Make the connections in the terminal block provided as indicated in (Fig.4), then after ensuring that the cable is firmly clamped, replace the front casing, cover and selector switch.

Safety Cut Out

• In the event of a malfunction that leads to an over temperature event the safety cut out will automatically cut off the electrical supply to the element (see Fig.4).
• The automatically resettable cut out can be reset by simply switching off the electricity supply, emptying the tank and refilling with cold water (open the inlet control valve or tap until cold water runs continuously) then waiting for the cut out to cool down and reset itself.

Commissioning & operation

• Do not switch on the heater until it is filled with water
• Open the inlet control valve or tap to allow the tank to fill with water, the tank will be full when water begins to run continuously from the spout or tap.
• Close the inlet control valve or tap and switch on the electrical supply, adjusting the temperature control to the required level.
• The contents of the water vessel will be heated to the selected temperature.
• During the heating cycle expansion will take place and water will drip from the spout or tap. This will cease when the operating temperature has been reached,(approx 10 mins. for the 5L models, approx. 20 mins. for the 10 litre models).
• Therefore always ensure that the spout outlet is positioned over the basin.
• Hot water is drawn off by opening the inlet control valve or tap, this allows cold water to enter the storage vessel as the heated water is displaced and is flowing out.

Safety Warning

• Under no circumstances is the water heater to be used if suspected of being frozen.
• If water ceases to flow, switch off the electrical supply immediately at the isolating switch.
• It is then recommended that a qualified Plumber/Electrician checks the unit.
• Any water can be drained via the cold inlet connection whilst in the original location.
• To remove the outer case, prise off the temperature selector switch and release the screw located beneath it.
• Remove the four front cover securing screws at the top and bottom of the unit, then the outer case can be lifted off.
