Dear customers:
In order to use this machine safely, please read this user's manual carefully
before using and installation, especially pay attention to each notice remark
for usage and maintenance. Also keep it carefully for later use. Heat pump
water heater is a professional machine, it may cause damage or hazard when
wrong installed. Relevant installation and maintenance shall be done by
technical people. Please contact our installation service for reference.
1).When using for the first time, check if all the wiring are correct before you
connect the unit to power supply.
2).The specifications of fuse is: AC250V, 5A.
3).The appliance must be fitted with means for disconnection from the supply mains
having a contact separation in all poles that provide full disconnection under
overvoltage category III conditions, and these means must be incorporated in the
fixed wiring in accordance with the wiring rules.
4). The running range of the heat pump:
the ambient temperature range -7 ~ 43℃;
outlet water range:12 ~60℃
the pressure of water 0.1MPa~0.7MPa.
5).If the power cord is damaged, please replace a new one offered from factory by
professional technicians.
6).Power plug's rated current shall be in accordance with the model you buy.
7).The units must be ground wired. Never connect the ground line on neutral line or
water pipe.
8).Product shall be singly assigned to a electrical leakage protection power .
9).Hot water above 50℃ may be burned, we suggest that you mix cold water with
hot water from water tank for use.
10).Any equipment must not be inserted inside the heat pump unit, in case any
accident or abnormal operation.
11).For your safety, please DO NOT change or mend the heat pump water heater
yourself.
12).Closed water heaters shall be marked with a statement that a pressure-relief
device is to be fitted in the installation, unless it is in corporatthe appliance.
13).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 supervision or instruction concerning
use of the appliance by a person responsible for their safety.
Important warning:
Ⅰ.PREFACE

14).The instructions shall contain the substance of the following: If the supply
cord is damaged, it must be replaced by the manufacturer, its service agent
or similarly qualified persons in order to avoid a hazard.
15). The water may drip from the discharge pipe of the pressure-relief device
and that this pipe must be left open to the atmosphere;the pressure-relief
device is to be operated regularly to remove lime deposits and to verify
that it is not blocked;
16). Transport using a forklift
When transported by a fork lift, the unit must remain mounted on the pallet.
The lifting rate should be kept to a minimum. Due to its top-heaviness, the
unit must be secured against tipping over.
To prevent any damage, the unit must be placed on a level surface!
17). Manual transport
For the manual transport, the wooden pallet can be used for bottom part.
Using ropes or carrying straps, a second or third handling configuration is
possible. With this type of handling, care must be taken that the max.
Permissible inclination angle of 60 degree is not exceeded.

Waste heat is useful heat
The standard heat exchanger of the hot-water heat pump enables direct
connection to a second heat generator, e.g. a solar heating system or a boiler.
Dehumidification in the recirculating air mode
Dehumidified air in the laundry room supports laundry drying and prevents
moisture-induced damage.
Cooling in the recirculating air mode
The room air is extracted from the storage room or a wine cellar,subsequently
cooled and dehumidified in the heat pump and finally re-introduced into the
room.Recreation rooms, boiler rooms or utility rooms areideal installation
sites. The air-ducts leading through warm sections must be insulated to prevent
the formation of condensation.
