● Do not put any foreign material on the unit.
● Do not put additional materials in the unit.
● Provide a strong and correct foundation so that:
A.Water module is not on an incline.
B.Abnormal sound does not occur.
●
Use the tap water and make sure that it is not
hard water. If hard water is used, the plate type
heat exchanger, electrical heating and various
valves will have a decrease in their service life .
Do not heat too hard underground water, spring
water and well water. If so, the service life of the
product can’t be guaranteed.
● Do not use galvanized parts in the water circuit
because they may cause corrosion.
● Do not cut off power supply of water module
when it is not used in winter. When shut down
and certain conditions are met, the unit may
automatically antifreeze.
● Circulating water must be drained if power cuts
off when it is not used for a long period of time. If
the circulating water is not drained, system will be
damaged by freezing.
● If the time interval from commissioning to use by
user is longer than one month, drain the circulat-
ing water in system.
● Do not install the water module, remote control-
ler and cable within approximately 3 meters
from strong electromagnetic wave radiators,
such as medical equipment.
● Water module can’t function normally under the
following circumstances:
*The electric power of the power transformer for
electricity supply is the same as that of water
module.
*Power source of large power electrical equip-
ment is too close to the power cord of water
module.
Equipment: such as elevator, container crane,
electrical railway rectifier, power inverter,
electric arc furnace, electric furnace, large
induction motor and large relay, which consume
much electricity.
Under the above circumstances, due to rapid
change in electric power consumption and switch
action, power cord of water module will generate
very large inductive surge voltage. Therefore, for
protecting power supply to water module, before
electrical installation, carefully examine the criteria
and specification for field installation.
2. Introduction
The air conditioner provides the functions of air
conditioning cooling, heating, floor heating, and
domestic hot water by air-refrigerant and
refrigerant-water heat pump circulation. These
functions are controlled by wire controller. (For
the use of air conditioner, refer to the user’s
manual of outdoor unit and indoor unit of air
conditioner).
The air conditioner can be used together with the
floor heating circuit and domestic water tank.
Children shall not play with the appliance.
Cleaning and user maintenance shall not be made
by children
without supervision.

instruction concerning use of the appliance in a safe
way and understand the hazards involved.
●
●
● The appliance shall be installed in accordance

● The A-weighted emission sound pressure level at
work stations is not exceeds dB(A).
If the supply cord is damaged, it must be replaced by
the manufacturer, it service agent or similary
qualified persons in order to aviod a hazard
