7. Before installation
IMPORTANT
Failure to observe these instructions will invalidate the guarantee. Handling / instal-
lation of this product is subject to the Health & Safety At Work act. This product must
be installed by a qualified professional that is certified for Unvented Water Heater
installation. Do not attempt to install this product yourself if you are not qualified.
7.1. Handling and transport
• You must not put any type of pressure on the upper part of the device, as it is not structural in
nature. The product must be transported and handled in the upright position only. The screen
should be facing the upper side. If tipped, the centre of gravity will shift. Please handle with care.
• The equipment can only be transpor ted horizontally during the last kilometre, taking care to
place some supports on the underside of the product in order not to lean against upper parts.
Positions allowed for transport/handling:
Positions NOT allowed for transport / handling:

7.2 . P a cka g i ng
• If the product is not installed immediately, it should remain in its protective packaging with all
pipe/end caps in place to prevent damage or dir t deposits.
• The equipment is supplied in a cardboard box, fixed to a pallet with screws. When removing the
screws from underneath the pallet, DO NOT tilt the product.
• Use a forklift or pallet truck to unload the equipment: these should have a load capacity of at
least 250 kg. Do not drop or lower the product suddenly.
• Unpacking the product must be carried out with care so the product does not become damaged.
Ensure all the supplied fittings have been removed from the packaging.
• Keep packaging out of reach of children. Make sure that the appliance is intact and not damaged.
If in doubt, do not use or install the product and contact us.
7.3. Location
Please adhere to the following conditions when choosing a location to install the product:
• Must be installed in a damp, frost-free environment, with containment systems in case of serious
water leaks.
• Must have structural integrity that is sufficiently robust to support the product weight when the
tank is full of water, plus a flat and level surface on which to install the product.
• Must allow access to water mains supply, hot and cold water pipework and a suitable electrical
supply.
• Be readily available for connection to condensation discharge pipe.
• Be sufficiently ventilated and illuminated (if necessary) and in a space of at least 20m3.
Figure 2 - minimum installation space

The product MUST NOT be installed in locations where:
• The air intake contains solvents, explosive matter, grease, dirt or dust/aerosol particles.
• It is outdoors, in rooms exposed to frost, ice or damp, or in rooms where there is a lot of steam/
vapour (e.g. a bathroom).
• It is sat on floor slabs containing wooden beams e.g. attics, to avoid mechanical vibrations.
• It is prohibited to connect vented exhaust hoods to ventilation systems.
Care must be taken when installing the product in a garage or outbuilding. All exposed pipework must
be sufficiently insulated to avoid frost or ice damage.
When installing the product, ensure that all labels are visible and pipework does not restrict any work
that needs to be carried out on the various components.
Ensure the product sits flat and level on a horizontal surface as shown in figure 2.
7.4. Ventilation
The product requires adequate ventilation (see figure 3). Install air ducts ensuring each one:
• Does not weigh down the product itself and allows for maintenance work.
• Is suitably protected to avoid foreign objects or materials getting inside the product.
• Does not exceed the recommended maximum length of 6 metres (with 2 x 90º elbow junctions).
• The total maximum allowable pressure drop for all components, including feed-throughs for
mounting on an external wall, in the pipe system does not exceed 100 Pa.
Figure 3 - Air duct for model with upper outlets
10
DALIS
Digital electric unvented heat pump
• During operation, the heat pump tends to lower the ambient temperature if the external air duct
is not carried out.
• An appropriate protection grid must be installed in line with the discharge pipe conveying air
to the outside, with the aim of avoiding foreign bodies from entering the equipment. In order to
guarantee maximum device performance, the grid chosen must ensure low pressure loss.
• In order to avoid the formation of condensate, insulate the air discharge pipes and the air duct
cover connections with steam-tight thermal cladding of an adequate thickness.
• If it is considered necessary in order to prevent flow noise, sound mufflers can be mounted. Fit
the pipes and connections to the heat pump with vibration damping systems.
WARNING
The simultaneous operation of an open flue firebox (e.g. an open flue fireplace) or
combustion chamber together with the product will cause a dangerous drop in am-
bient pressure. This could cause the blackflow of exhaust gas into the environment
itself.
Do not use the product with an open flue firebox or combustion chamber. Use only
sealed (approved) chamber fireboxes or combustion chambers with a separate duct
for combustion air.
Keep the doors of the room closed and hermetically sealed if they do not have a
supply of combustion air in common with inhabited areas.
7.4.1. Ventilation accessories
Suitable ventilation accessories are available on the market, which are designed for simple and
efficient heat pump water connections. See below for ventilation accessories required for successful
and correct installation:

When carrying out the installation you must take care, so that:
• Extra pressure is not applied to the product e.g. by leaning on it.
• Foreign bodies and materials cannot enter inside the product.
• The selected pressure protection grid ensures low pressure loss.
• The air discharge pipes and roof connections are isolated with steam-tight thermal coating to
avoid condensation.

8.2. Non-standard installations
One of the unique features of heat pump heating systems is that they create a considerable drop in
air temperature usually expelled outdoors. The expelled air, in addition to being colder than the air in
the environment, is also fully dehumidified. This means that the flow of air can be fed back inside the
building again to cool rooms or spaces during warmer months, such as the summer. A dual air outlet
pipe should be installed, with 2 dampers attached, so that the expelled air flow can be directed either
indoors or outdoors - see figure 6a and 6b.
Figure 6a - installation in summer Figure 6b - installation in winter
8.3. Cold water supply
For safe per formance of the product, the tank should be directly fed by an uninterrupted supply pipe
that connects to the pressure reducing valve with a maximum supply pressure of 0.9 MPa - see figure
5. The product should not be used with a supply pressure below 0.15 MPa and a flow rate of less than
20 litres per minute. The following criteria must also be met:
• Cold water supply must come directly from the cold water mains after the mains stop valve to
the p rop e r t y.
• The inside diameter of the cold water pipework must be at least 19mm.
• Pipework should meet the water supply regulations for wholesome water.

A dirt/impurities filter must be installed in the cold water pipe inlet. The product must not operate with
a water hardness below 12ºF or hardness above 25ºF. If this is the case, then a suitably calibrated and
monitored water softener must be used.
This product is equipped with a pressure and T/P valve that complies with the BS EN 1490:2000
standard. It is factory set to operate on 7 bars pressure and a temperature of 90ºC.
The T/P safety valve for protection against over pressure and temperature must be operated regularly
to remove lime scale deposits and check it is not blocked. For more information on the T/P valve
please see section 8.9.
In case an expansion vessel is not installed, make sure that the cold water intake does not contain
any non-return valves.
WARNING
This product is capable of producing domestic hot water over 60ºC. To protect
against burns, we recommend a thermostatic mixing valve (sold separately) be in-
stalled in the hot water pipe. Also ensure there is no human burn risk at drain pipe
connecting T/P valve.
See figures 9a and 9 b for an example of a water supply connection.
