- Thermal insulation of the room. This provides
efficiency of the appliance and prevents the
water from freezing.
1.2. Requirements for installaon.
- The length of connecng pipes between the
water tank and consumer must be as short as
possible.
- Before connecng the water tank to the
installaon, check all screw connecons
(plug and etc.). In very rare cases - during
transportaon, loading and unloading
operaons - the screw connecons may be
loosen.
- Before commissioning, check the installaon
for leaks
- Do not exceed the working pressure of 3 bar
for buer tank and 6 bar for hygienic stainless
steel coil.
- If there is a risk of freezing of water in the
tank - drain the tank completely or let the
water tank works connuously.
2. DESCRIPTION ON HYGIENIC COMBI TANK
Hygienic Combi tanks are used to produce
and accumulate sanitary hot water and hot
water for space-heang system.
Coil-in-Tank construcon - Flexible stainless-
steel coil for sanitary hot water + Buer tank
powering space-heang system. Sanitary
water heats up instantaneously as it ows
through the large surface stainless coil. Thus
water is delivered hot while sll fresh and
clean of deposions.
HYG-B series - Inlet/Outlet arrangement – 90
angle degrees.
HYG-B models, the heat source is an electric
heater.
HYG-BR models have a built-in heat exchanger
(coil type) designed to connect to a solar
installation or boiler. Option for installation of
an electric heating element.
HYG-BR2 models have two built-in heat
exchanger (coil type) for connection to the
solar system and boiler. Option for installation
of an electric heating element.
Dear Customers,
We strongly hope that the appliance you have
bought from us will contribute to creating
comfort at you homes and decreasing the
energy expenditure.
This manual contains important information
for the safe and correct installation, start-up
and trouble-free operation and maintenance
of the water heater.
Hygienic Combi Tanks can be used only in the
manner described in this manual – to produce
and accumulate sanitary hot water and hot
water for space-heating system.
The application and any other was the area
of operation is not recommended by the
manufacturer and is not responsible for the
occurrence of defects or failures.
1. INSTRUCTIONS TO INSTALLER
The preparation, installation and
commissioning must be performed
by an authorized installer / service.
During installation and operation, the country
specific requirements and regulations must be
observed:
• local construction regulations on installation
of water tank; weight of the boiler to comply
with the stability of the floor of the room
where it will be installed.
• regulations and norms concerning the fitting
of theinstallation with safety devices.
• safety during installation - personal
protective equipment
iUse only original SUNSYSTEM
parts.
1.1. Requirements to Water Tank installation
room
When choosing a room for tank installation
observe the following requirements:
- to have a drainage channel. Some
maintenance procedures require draining of
all water from the tank.

2.1. Removable insulaon and outer casing.
The quality of the insulaon of a water heater is
a key factor for its heat conservaon capability
and energy eciency.
All Hygienic Combi tanks HYG series/ HYG-B
series have Removable insulaon with
thickness 100 mm (DIN 4753, part 8) and outer
casing of PVC with RAL 9006 color.
2.2. Water tank.
Floor standing. Water tank is made of
low-carbon steel S235JR, DHW tube of
sanitary grade stainless steel -316L, heats up
instantaneously.
All threads are internal (see technical
parameters).
2.3. Electric heang element.
Outlet connection of electric heating element
1 ½“ :
3000W/230V;4500W/230V;
6000W/230V; 7500W/400V.

The connection of the electric
heating element to the electric power
supply must be done by a qualified
electricians.
When connect the heating element
to the electric network, make sure
that it is properly grounded.
Wiring diagrams
2.4. Thermostat
The thermostat may be adjusted by the user
within the range 30°С ÷ 80°С, and the thermal
protecon would go o in case the water
reaches 95°С.
This is an adjustable double THERMOSTAT
which is designed to regulate the water
temperature and ensures safety tolerance;
it can be manually adjusted (TLSC model) or
automacally adjusted (TLSC/A model).

Stop (Shut-off) valves should never
be installed between a safety (relief)
valve and the tank. It is recommended
once a year to check the operation of

vent from normal operaon under proper and
normal use, installaon and maintenance for
the intended funcons of the products, for a
period set out in the warranty cercate of
the respecve water heater model you have
bought. The warranty period begins from the
date indicated in the purchase invoice. If a
product or any component there of is deter-
mined to be defecve in manufacture or ma-
terials, NES Ltd. will repair or replace the de-

6.2. Exclusions and Limitaons of Warranty
Coverage
a) The customer can claim warranty during
warranty period of respecve product im-
mediately aer any defects have been deter-
mined, except for in case of noceable defects
at the moment of purchase, in which case the
customer must make the claim at the shop
immediately aer nocing the defect as it is
provided for in the general condions of sale.

5. TRANSPORT AND PACKAGING
We recommend to transport the water tank to
the installation site in its packaging placed on
the pallet, and stretch foil.
During transport and installation, depending
on the weight, appropriate safety equipment
must be used in accordance with Directive
2006/42/EC.
When transporting items weighing more than
30 kg, the use of pallet jack, fork truck or other
hoisting devices is a must.
Hygienic Combi Tanks can be with or without
insulaon. They are secured on a pallet packed
with foil.
Insulaon, decorave cover and rosees can
be delivered separately.
Advantages:
• Easy transportaon (takes less space
at transportaon).
• Easy conveyance to the place of
installaon.
• Easy and quick packing of water
heaters with so insulaon. All
necessary openings in the casing are
made beforehand, and the installer
has only to nd them and take them
out.
The casing is fastened by a zipper at
the assembly plaorm.
