1.4Guarantee registration
ThankyouforinstallinganewGlow-wormapplianceinyourhome. Glow-worm appliances are manufactured to the very
highest standard so we are pleased to offer our customers a Comprehensive Guarantee.
This product is guaranteed for 24 months from the date of installation or 30 months from the date of manufacture, whichever is the shorter, for parts and labour.
The secondyear of guarantee, from the beginning of the 13th month onwards after installation or manufacture, is conditional upon the heat pump having been serviced by a competent person approved at the time by the Health and Safety Executive, in accordance with the manufacturer’s recommendations. We strongly recommend regular servicing ofyour appliance, but where the condition is not met, any chargeable spare parts or components issued within the applicable guarantee period still benefit from a 12 month warranty from the date of issue by the manufacturer.
We recommendyou complete and return as soon as possible your guarantee registration card (delivered with the hydraulic module). Ifyour guarantee registration card is missing you can obtain a copy or recordyour registration by telephoning the Glow-worm Customer Service number 01773 828100.
2Appliance description
2.1Safety devices
-- This appliance is designed for use in heating with an external temperature of between -20°Cand 30°C. Outside this range, the heat pump stops.
-- A set of security devices based on measuring the temperature within the circuits and the current in the compressor protects it against excess pressure in the refrigerating fluid.
-- A flow detector protects the appliance as a whole.
-- To prevent stagnation of the refrigerant fluid when the compressor is stopped, a safety device is activated when the outside temperature lowers. The compressor is then heated by a low electrical current through the motor windings,
-- A temperature sensor on exit from the compressor limits the functioning of the heat pump when the temperature measured by this sensor is greater than 100°C. From 117°C, the heat pump stops.
-- A temperature sensor on the tubular heat exchanger and a tachometer on the fan checks that the fan is working.
-- A water flow sensor ensures the security of the water circulation. If the flow is too low (< 420 l/h), the appliance stops and re-starts when the flow comes within the normal functioning range (>500l/h).

2.3.2Local regulations
Benchmarkplaces 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 a competent person approved at
the time by the Health and Safety Executive and that it meets the requirements of the appropriate Building Regulations.
The BenchmarkChecklist 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 workin accordance with the BenchmarkCode of Practice which is available from the Heating and Hotwater Industry Council who manage and promote the Scheme.
• Visit www.centralheating.co.ukfor more information.
2.4Concept of operation
A heat pump (HP) is a thermodynamic machine which transfers heat from one location to another. To do so, it employs the characteristics of a refrigerant fluid.
The system is composed of the following circuits:
-- The refrigeration circuit which transfers heat to the water
circuit following the evaporation, compression, condensation
and expansion of the fluid.
-- The heating circuit.

7Appliance location
7.1Heat pump location
7.1.1Instructions
•Before choosing a site for the appliance, carefully read the safety warnings and installation manual.
•Ensure there is sufficient space available for the appliance, taking care that minimum clearances are adhered to ensure that the connections to the water, gas and flue can be accessed and inspected (see chapter Clearances).
•Observe current regulations.
•Install the appliance outside.
•Do not install the appliance:
-- near a heat source,
-- near flammable materials,
-- near the ventilation points of adjacent buildings -- beneath deciduous trees.
•Take into account the following when installing the heat pump: -- prevailing winds,
-- the noise generated by the fan and the compressor -- the visual impact on the surrounding neighbourhood.
•Avoid areas exposed to strong winds directed against the appliance’s air outlet.
•Settheapplianceononeofthefollowingsupports:
-- concrete slabs, -- crane beam,
-- concrete blocks.
•Do not install the fan facing the nearby windows. If necessary, install a noise barrier.
•To avoid transmission ofvibrations to the surrounding buildings:
-- use hoses for water connections, -- install anti-vibration pads.
•Ensure that the appliance is protected from water and from snow.
•Do not expose the heat pump to corrosive or dusty atmospheres (near to dirt roads, for example).
•Do not place near to stale air extraction fans.
•Allow room for electricity cables (high and low voltage).
•Explain these requirements to the appliance user.
7.1.2Discharge of condensates
>100mm 
• Make allowance for a condensate discharge circuit.
7.1.3Regulations
•Please ensure that all correct permissions have been obtained from the local planning office, prior to siting the appliance.
