It is recommended to use a sack barrow for lifting and moving the packaged NUOS.
The bottom and top of the carton has polystyrene padding to protect the unit.
Carrying the NUOS will require two fit persons.
IMPORTANT
The appliance should be kept in a vertical position when transported or stored. During
manual handling it can be carried at an angle (i.e. in a sack barrow) or horizontally.
If handling entails moving the product in a position other than vertical, wait at least 3
hours before starting the appliance once it is in the correct vertical position. This will
ensure that the lubricating oil in the refrigeration circuit is correctly placed in order to
avoid the compressor becoming damaged.
IMPORTANT
Failure to follow these instructions correctly may invalidate the guarantee.
IMPORTANT
The NUOS External Air Source Heat Pump Water Heater is an UNVENTED HOT WATER
SYSTEM.
Unvented domestic hot water heating systems must be installed to comply with the current
Building Regulations, British Standards and any applicable local regulations.
IMPORTANT
Hard Water. Where the mains total water hardness exceeds 200 ppm, provision should be
made to treat the feed water to reduce the rate of limescale accumulation.
IMPORTANT - The Benchmark Scheme
Benchmark places responsibilities on both manufacturers and installers.
The purpose is to ensure that customers are provided with the correct equipment for their
needs, that it is installed, commissioned and serviced in accordance with the manufacturer's
instructions by competent persons and that it meets the requirements of the appropriate
Building Regulations. The Benchmark Checklist can be used to demonstrate compliance
with Building Regulations and should be provided to the customer for future reference.
Installers are required to carry out installation, commissioning and servicing work in
accordance with the Benchmark Code of Practice which is available from the Heating and
Hot Water Industry Council who manage and promote the Scheme.
