DC Inverter Heat Pump
1.Warning:
2. Safety information:
O
Sundez DC inverter heat pumps are constructed according to the European technical standards
and safety regulations. The heat pumps are designed and built for heating or domestic hot water
production (DHW). In the event of improper use, dangers to the user or third parties may arise, as
well as damage to the heat pump and other objects. Any use not expressly indicated in this
manual is not permitted.
Safe keeping of the documentation
The installation manual should be issued to the end user of the heating system as part of the
handover and training process. It is then the responsibility of the user to keep the manuals safe
for future use by maintenance engineers.
Installation and maintenance carried out by professionist
The installation and maintenence of this heat pump must be carried out by a registered
professionist, who is suitably trained and qualified, including any stipulations laid down by law.
The appliance must be installed in such a way as to enable maintenance and/or repairs to be
carried out. The appliance warranty does not cover the costs for fork lift trucks, scaffolding, or
other elevation systems that may become necessar y for carrying out servicing under warranty.
The warranty will be invalid if the advice given within the Installation instructions is not followed.
Use in compliance with the documentation.
This manual describes installation and ser vice procedures for implementation by specialists. This
appliance is not intended for use by persons (including children) with reduced physical, sensory or
mental capabilities, or lack of experience and knowledge, unless they have been given super vision
or instruction concerning use of the appliance by a person responsible for their safety. Children
should be supervised to ensure that they do not play with the appliance. Rights to make any design
or technical modifications are reser ved.
Please make sure the water flow is sufficient all the time.
All ground line connections must be prepared in accordance with relevant local regulations.
To reduce the risk of electrical insulation faults, you first make the connection of the protective
conductor of the heat pump safe according to local regulations.
When installation, make sure the inside wires are apar t from hot or moving parts [ eg:
compressor, fan] of the system to avoid damage of the wires.
Anti-freezing measures must be well done to avoid damage to the water system and the heat
pump water heat exchanger.
It is very dangerous work done at the facility without previously cutting off the electricity from
the main power source.
When installing the system, please ensure that no contaminants enter the water cycle.
Additional current protection circuit breaker must be installed for electrical safety.

Energy Saving and Environmental Friendly
With Advanced DC inverter technology, it can change the frequency and saves 40% energy than
normal heat pump in practical operation. The R410A refrigerant is friendly without pollution to the
environment.
Full Consideration for Noise Control
Compressor rubber feet are specially selected for reducing vibration. Specially, compressor is
located in the closed and isolated space inside the heat pump unit, without noise given out. WellÂbalanced fans and fan motors, with the motors, with the optimized fan holder, contributes to the
low noiseoperation.The cabinet inside is insulated to reduce noise transmission.
DC Inver ter Heat Pump Does Not Need Sof t-starter
DC inverter heat pump technology not only saves energy, but also with soft starting feature. The
compressor motor is DC inverter type, and its starting is already soft-starting, so, no need to install
additional sof t-starter, and its starting would not cause compact to your home power network.
Strong Cabinet
Standard unit fabrication consists of heavy gage galvanized sheet metal cabinet construction that
provides maximum strength. All interior sheet metal surfaces arepowder-painted for maximum
corrosion protection to ensure resilience for long term vitality. Compact, stackable cabinets are
designed to minimize installation space.
Reliable Design and Strict Quality Control
Standard safety features for the refrigerant circuit include high-pressure switch and low-pressure
switch to detect loss of refrigerant, as well as deficient water flow. Equipment safety features
include water loop temperature monitoring, voltage protection, water coil freeze protection. All
safety features are tested and run at the factor y to assure proper operation of all components and
safety switches. All components are carefully designed and selected for endurance, durability, and
carefree day-to-day operation. Each unit is fully tested in per formance and safety before it is
exported.
Easy Installation
Sundez DC inverter heat pumps are designed for easy installation. The refrigerant R410A has
already stored in the outdoor unit when ex-factory. The refrigerant can be released to the indoor
unit and the connecting copper tubes after vacuuming the indoor unit and the copper tubes. The
communication between the indoor unit and outdoor unit is simple with the fast plug, offering
power for circulation pump and signal for sensors and control panel on the indoor unit.
Simple Maintenance and Ser vice ability
Full access for maintenance or ser vice is provided from the maintenance panel, for better flexibility
in confined space. Easy removal of the control box from the unit provides access to all refrigerant
components. The refrigerant circuit is easily tested and serviced through the use of high and low
pressure ports integral to the refrigerant circuit.

7.2 Installation of Outdoor Unit
X
Hig her tha n snow de pth
Heat pump should be installed on a solid level base that can take the weight, preferably a concrete
foundation. If concrete slabs are used they must rest on asphalt or shingle.
The concrete foundation or slabs must be positioned so that the lower edge of the evaporator is at
the level of the local snow depth.
Heat pump should not be positioned next to sensitive walls, for example, next to a bedroom.
Also ensure that the placement does not inconvenience the neighbors.
Heat pump must not be placed so that recirculation of the outdoor air can occur ; this causes lower
output and impaired efficiency.
Large amounts of condensation water as well as melt water from defrosting can be produced.
Condensation water must be led off to a drain or similar.
The outdoor unit should be installed in a ventilated place, with enough space for air inlet and
outlet, while without thermal radiation or other heat source. Besides, the air outlet should not
be against the wind.
Generally, horizontal air flow type heat pump does not need
sheltering. The structure design has protected all internal
components against rain and sunshine. A shelter is necessar y to
avoid snow burying onto the heat pump in heavily snowy area.
Please make sure the standardized voltage 220V is stably
accessible to the heat pump, other wise the performance would be
influenced.
The foundation of the heat pump can be cement or steel structure.
Anti-vibration rubber and a flat foundation should be taken into
account. The foundation structure can be flexibly designed
according to the working weight of the heat pump (Please see the
technical data in this manual).
