5 Safety
• Installation and any service work on the
heat pump may only be performed by
authorised and qualified installer and after
-sales service technicians.
• This device is not suitable for operation
with an electrical generator and any
attempt to do so will void warranty.
• If the heat pump may be disconnected
from power supply for prolonged periods
of time or where power supplies are
susceptible to failure, antifreeze must be
added to the system.
• Additional heating may be required if heat
pump is intended to dry out a new or
renovated building, as the initial heat load
will be higher than the calculated load.
• Products not installed with the Dimplex
hydraulics packs will not be supported by
Dimplex. This includes but is not limited to
thermal stores.
• This appliance can be used by children
aged from 8 years and persons with
reduced physical, sensory or mental
capabilities, or lack of experience and
knowledge, provided that they have been
given supervision or instruction
concerning use of the appliance in a safe
way and understand the hazards involved.
Children must not play with the appliance.
Cleaning and user maintenance must not
be carried out by children without
supervision.
6 Defrost
During colder weather, frost builds up on the
evaporator coil inside the heat pump. If this
frost remains in the evaporator, it will cause
blockages and will prevent air from flowing
efficiently through the heat pump, which will
result in poor performance. Therefore, when
frost starts to form on the evaporator coil, the
heat pump runs a defrost cycle. This lasts for
approximately 4 minutes and melts any frost
that is present.
Approximately 2 litres of condensate water is
drained from the system every time a defrost
cycle occurs. Therefore, it is essential that this
water is drained correctly. The heat pump is
supplied with a condensate pipe which must be
fed into a drain or soak away to allow for safe
disposal of the excess water. This will prevent
icy patches forming on footpaths or patios in
colder weather
7 Maintenance
Please see section 9 of the Installation manual
for ‘System Health Checks / Maintenance’
advice.
