We accept no liability should any damage result from the failure to comply with theins-
tructions contained in this technical manual.
Essential recommendations for safety
• It is strictly prohibited to carry out any modifications to the appliance without
the manufacturer’s prior and written agreement.
• The product must be installed by a qualified engineer, in accordance with
applicable local standards and regulations.
• The installation must comply with the instructions contained in this manual and
with the standards and regulations applicable to domestic hot water tanks.
• Failure to comply with the instructions in this manual could result in personal
injury or a risk of environmental pollution.
• The manufacturer declines all liability for any damage caused as a result of
incorrect installation or in the event of the use of appliances or accessories that
are not specified by the manufacturer.
Essential recommendations for the correct operation of the appliance
• In case of anomaly, please call your installer for advice.
• Faulty parts may only be replaced by genuine parts.
• Our water heaters are designed and manufactured for the exclusive purpose of
heating and storing domestic hot water.
• The domestic hot water heaters must only be heated using hot water in a closed
circuit.
General remarks
• The availability of certain models as well as their accessories may vary according
to markets.

SAFETY INSTRUCTIONS
General remarks
• Connections (electrical, hydraulic) must be carried out in accordance with
applicable standards and regulations.
• If the water drawing off point is far from the tank, installing an auxiliary DHW
loop can allow to get hot water more quickly at all times.
Essential instructions forthecorrect operation ofthesystem
• The tank must be installed in a dry and protected area.
• Install the appliance to ensure easy access at all times.
• To avoid any risk of corrosion, connect the stainless steel tank directly to the
earth. Use an adjustable earth clamp (see example below) on one of the DHW
connections to connect to the earth. Advised copper wire section: 2.5mm².
• Make sure to install a pressure reducing valve set at 4.5 bar in the DHW circuit
if the supply pressure is higher than 6 bar.
• On the DHW circuit, install an approved safety group, comprised of a safety
valve set at 7 bar, a check valve and a stop valve.
• Make sure that the outlet of the safety unit goes directly to the sewer to avoid
any potential damage.
• Do not install the safety group above the tank to avoid water discharge on to
the tank.

Essential instructions forthe safety of persons and the environment
• Hot water can burn!
In the event of small amounts of hot water repeatedly being drawn off, a
stratification effect can develop in the tank. The upper hot water layer may
then reach very high temperatures.
• ACV recommends using apre-set thermostatic mixing valve in order to provide
hot water at a maximum of 60°C.
• Water heated to wash clothes, dishes and for other uses can cause serious
burns.
• In order to avoid exposure to extremely hot water that can cause serious burns,
never leave children, old people, disabled or handicapped people in the bath
orshower alone.
• Never allow young children to turn on the hot water or fill their own bath.
• Adjust the water temperature in accordance with usage and plumbing
regulations.
• The risk of developing bacteria exists, including “Legionella pneumophila”,
if a minimum temperature of 60°C is not maintained in both the DHW tank
andthe hot water distribution network.
Essential instructions for the electrical safety
• Only an approved installer is authorized to carry out the electrical connections.
• Make sure that the appliance is connected to the earth.
• Install a 2-way switch and a fuse or circuit breaker of the recommended rating
outside the appliance, so as to be able to shut power down when servicing the
appliance or before performing any operation on it.
• Shut down external electrical supply of the appliance before performing any
operation on the electrical circuit.
• This appliance is not intended for use by persons (including children) with
reduced physical, sensory or mental capabilities, or lack of experience and
knowledge, unless supervised or unless they have been given instruction
concerning the use of the appliance by a person responsible for their safety.

PACKING CONTENTS
All appliances are delivered, tested and packaged separately.
General Remark
• The hot water tank may be installed either on the floor or on a wall using
the provided wall-mounting kit (depending on the model).
Essential instructions for the correct operation of the installation
• When hung on a wall, the SLEW models must be assembled with the
heating element to the bottom (DHW pipes to the bottom).
• In horizontal configuration (SL only), the peak output and the first hour
continuous output will be reduced. In this case, we recommend to
oversize the tank.

G3 REQUIREMENTS AND GUIDANCE
Discharge pipe from safety valves
The Building Regulation G3 requires that any discharge from an unvented system is con-
veyed to where it is visible, but will not cause danger to persons in or about the building.
The tundish and discharge pipes should be fitted in accordance with the requirements and
guidance notes of Building Regulation G3. The G3 Requirements and Guidance sections
3.50 - 3.63 are detailed below.
For discharge pipe arrangements not covered by G3 Guidance advice should be sought
from your local Building Control Ocer.
Main characteristics :
• Any discharge pipe connected to the pressure relief devices (Expansion Valve and
Temperature/Pressure Relief Valve) must be installed in a continuously downward di-
rection and in a frost free environment.
• Water may drip from the discharge pipe of the pressure relief device.
• This pipe must be left open to the atmosphere.
• The pressure relief device is to be operated regularly to remove lime deposits and to
verify that it is not blocked.
A typical discharge pipe arrangement is shown on next page.
General remarks
• Discharge pipe-work D2 can now be a plastic pipe but only pipes that have
been tested to a minimum 110°C must be used.
• Discharge pipe D2 can now be plumbed into the soil stack but only soil stacks
that can handle temperatures of 99°C or greater should be used.
Extract from “The Building Regulation G3” :
Discharge pipe D1
3.50 Safety devices such as temperature relief valves or combined temperature and pres-
sure and pressure relief valves (see paragraphs 3.13 or 3.18) should discharge either
directly or by way of a manifold via a short length of metal pipe (D1) to a tundish.
3.51 The diameter of discharge pipe (D1) should be not less than the nominal outlet size of
the temperature relief valve.
3.52 Where a manifold is used it should be sized to accept and discharge the total di-
scharge from the discharge pipes connected to it.
3.53 Where valves other than the temperature and pressure relief valve from a single
unvented hot water system discharge by way of the same manifold that is used by the
safety devices, the manifold should be factory fitted as part of the hot water storage
system unit or package.
Tundish
3.54 The tundish should be vertical, located in the same space as the unvented hot water
storage system and be fitted as close as possible to, and lower than, the valve, with
no more than 600mm of pipe between the valve outlet and the tundish.
Note: To comply with the Water Supply (Water Fittings) Regulations, the tundish should in-
corporate a suitable air gap.
