1.4 Guarantee registration
Thank you for installing a new Glow-worm appliance in your home.
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 second year 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
of your 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

2 Appliance description
2.1 Safety devices
- The appliance is designed to function in heating with an
exterior temperature of -7°C to 25°C. At temperatures
beyond this range, the appliance ceases functioning until the
outside temperature is returns to between -5°C and 25°C.
- The appliance is designed to function in cooling with an
exterior temperature of 16°C to 48°C. At temperatures
beyond this range, the appliance ceases functioning until the
outside temperature is returns to between 18°C and 47°C.
- Prior to each start-up, the heat pump’s electronics ensure
that the sensors are connected.
- A high pressure switch limits the operation of the appliance
when the refrigerant fluid pressure exceeds 42 bars (42 x 10 5
Pa).
- A low-temperature compressor protection device checks the
outdoor temperature prior to switching on the heat pump. If
below 12C, the compressor case heater is activated, to avoid
compressor damage.
- A compressor output temperature sensor limits the operation
of the heat pump when the temperature measured by the
sensor exceeds 105°C.
- A temperature sensor located on the heat exchanger tube
enables the functioning of the fan.
- A water flow sensor ensures correct water circulation. If the
flow is too low (<500 l / h), the unit stops and restarts once
the flow has returned to within the normal range of operation.
- The maximum output temperature for the water circuit is
55°C. When this temperature is exceeded, the appliance
stops. The heat pump restarts when the temperature drops
below 42°C.
