Dear heating engineer,
We would like to congratulate you on having recommended an R storage cylinder unit: a modern product that’s capable of ensuring a high degree of reliability, efficiency, quality, and safety. While your technical skills and knowledge will certainly be more than sufficient, this booklet contains all the information that we have deemed necessary for the device’s correct and easy installation.

Thank you again, and keep up the good work, The following symbols are used in this manual:

• CAUTION! Identifies actions that require caution and adequate preparation.
• STOP! Identifies actions that you MUST NOT do.

GENERAL SAFETY INFORMATION

• Check that the product is complete, undamaged, and as ordered as soon as you receive it. Report any discrepancies or damage to the R dealer who sold it.
• This product must be installed by a legally qualified heating engineer. On completion of the installation, the installer must issue the owner with a declaration of conformity confirming that the installation has been completed to the highest standards in compliance with the instructions provided by R in this instruction manual and that it conforms to all applicable laws and standards.
• This product must only be used for the purpose for which it is designed and made, as specified by R. R. declines all responsibility, contractual or other, for damage to property or injury to persons or animals caused by improper installation, adjustment, maintenance, or use.
• The product must be serviced at least once a year. Servicing must be arranged in advance with the R Technical Assistance Service.
• All servicing and repairs must be performed by a qualified heating engineer.
• If water leaks from the storage cylinder, turn off the water supply and contact R’s Technical Assistance Service or a qualified heating engineer immediately.
• If the product is not going to be used for an extended period, contact the manufacturer’s Technical Assistance Service to have at least the following operations performed:
  1. Close the shut-off cocks for the domestic hot water circuit
  2. Shut down the boiler connected to the storage cylinder as instructed in its manual
  3. Switch the storage cylinder OFF at the control panel (if fitted) and at the mains power switch
  4. Drain the central heating circuit and domestic hot water circuit if there is any risk of freezing.
• This instruction manual is an integral part of the product. It must be kept safe and must ALWAYS accompany the product, even if it is sold to another owner or transferred to another user or to another installation. If you lose this manual, order a replacement immediately. Keep the product purchase documents to be presented to the R-authorised Technical Assistance Service to request a service call under warranty.

At the end of its life, the product should not be disposed of as solid urban waste, but rather it should be handed over to a differentiated waste collection center.

PRECAUTIONS

The operation of any appliance that uses electrical power demands that several fundamental safety precautions be respected.

In particular:

• Never attempt to install the system without using suitable personal protection equipment and without following all applicable occupational safety standards.
• Do not touch the product when barefoot or wet if it has any electrical accessories installed in it.
• Never clean or service the storage cylinder without first turning the mains power switch OFF to disconnect all electrical accessories (if fitted) from the mains electricity supply.
• Never pull, disconnect, or twist any electrical cables coming from the appliance even if it is disconnected from the mains electricity supply.
• Do not expose the storage cylinder to the elements. It is not designed for use outdoors.
• Do not allow children or infirm persons to operate the system unsupervised.
• Do not dispose of packaging material into the environment, or leave it within the reach of children, since it can become a potential hazard. Dispose of packaging material in compliance with applicable legislation.

IDENTIFICATION

The R 7200 V PRIME solar heaters can be identified by:

This 7200 V PRIME storage cylinder is delivered without a charging pump. A suitably rated pump must therefore be provided and installed separately.

ASSEMBLY OF THE INSULATION AND THE LINING

7200 V PRIME 800 – 1000
The assembly of the insulation and lining components must be performed at the site of installation to facilitate passage through any doors and/or entries to the room.

Proceed as follows:

• Assemble the insulating covers (1) around the body of the heater, making sure that the engagement points on the edges are positioned correctly. The edges are not required to be closed completely
• Place the front protection plate (2) correctly on the attachments
• Put the washers on the attachments (3)
• Place the rear protection plate by closing the interlocking flaps (4) without closing completely (leave one tooth open)
• Apply the upper insulation (5) and the upper cover (6) (to insert the cover, exert a light and homogeneous pressure)
• Close the interlocking flaps (4) completely, which were previously left with an open tooth
• Apply the technical data plate and serial number plate

If disassembling is required, proceed in reverse order.

• Wear suitable personal protective equipment and use suitable safety devices.
• Do not dispose of packaging material into the environment, or leave it within the reach of children, since it can become a potential hazard.
• Dispose of packaging material in compliance with applicable legislation.

PLACE OF INSTALLATION
R 7200 V PRIME storage cylinders can be installed in any room where there is no specific requirement for an electrical protection rating higher than IP X0D.

Respect the minimum specified installation distances to ensure correct installation and access for maintenance. Adjust the feet to ensure that the storage cylinder is perfectly level.

Installation in older systems and systems requiring modernization

When the R 7200 V PRIME appliance is installed on old systems or ones that need modernizing, make sure that:

• Make sure that the system is fitted with safety and control devices by applicable legislation and standards
• Make sure that the central heating circuit has been flushed out to remove all sludge and lime scale and has been vented and seal tested
• Make sure that a suitable water treatment system is installed if the quality of the supply/recirculation water demands. (Refer to the reference values listed in the table alongside.)

MAINTENANCE

Perform the following operations before beginning any maintenance:

• Switch the electricity supply to the storage cylinder’s valve group and any associated boiler OFF at the main switch and the control panel
• Close the shut-off cocks for the domestic hot water circuit
• Drain the storage cylinder’s DHW (secondary) water circuit.

CLEANING AND REMOVING INTERNAL COMPONENTS

EXTERNAL CLEANING

• Clean the outside of the storage cylinder with a soft cloth damped in soapy water.
• Do not use abrasive products, petrol, or triethylene.

INTERNAL CLEANING
Removing and checking the magnesium anode

• Remove the cover (1) (removing the screws first from models 800 and 1000), and remove the insulation (2). Use a suitable wrench to unscrew the anode holder (3)
• Check the magnesium anode for wear and replace it if necessary.

MODELS 7200 V PRIME 800 – 1000
Removing and checking the second magnesium anode

• Remove the plug (5) and use a suitable wrench to unscrew the anode holder (6).
• Check the magnesium anode for wear and replace it if necessary.

On completion of cleaning, follow the above steps in the reverse order to refit all removed parts.

NOTE : Tighten the anode plug to a torque of 25-30 Nm.

RECYCLING AND DISPOSAL
The device is primarily composed of:

At the end of the device’s useful life, these components must be separated and disposed of according to current regulations in the country of installation.
