1.1. Requirements to SWP 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.
- 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.
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.
The water heater can be used for
producing of domestic hot water (DHW)
only in the manner described in this
manual.
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

2. DESCRIPTON
Water heaters for heat pump systems
SWP series includes:
SWP NL one coil water heater
SWP N one coil water heater
SWP 2N double coil water heater
With extra-sized heat exchanger surface;
suitable for solar water heang, space-
heang,andheatpump
systems with large number of consumers
Product features:
• Floor standing
• Vercalmodicaons
•High efficiency insulation and outer
casing of PVC
•Complex corrosion protection realized
by means of titanium enamel and anode
protection.
• All threads are internal.
• Convenient inspection opening.
• High efficiency heat exchanger coil/coils
(SWP N/SWP 2N).
The height of SWP NL model is
compensated by its smaller diameter; heat
exchanger coil with increased surface.
• Easy installation.
•Suitableforsolarwaterheating,space-
heating,andheatpump
systems with large number of consumers
2.1. High eciency 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 water heaters SWP series have a high
eciency insulaon (DIN 4753, part 8)
and outer casing of PVC with RAL 9006.
2.2. Water tank
Water tank is made of low-carbon steel
S235JR,ghtlycoveredwithtanium
enamel on the inside. It is then baked to
produceasmoothanduniformdeposion
- free glazing. Thus the domesc hot
waterremainsclean,andthewatertankis
protected against corrosion.
All threads are internal (see technical
parameters).
2.3. Electric heang element (opon).
