WARNING! Before installation and operation with the buffer tank, read
carefully the present manual! In terms of the type of water container buffer
tanks are classified
as made of three different materials – carbon steel with enamel protective
coating, carbon steel without coating and corrosion-resistant chrome-nickel
alloy steel.
PURPOSE Enamelled buffer tanks are designed for storage of domestic hot water
(DHW).
Buffer tanks without protective coating are designed for use in central
heating and general heating systems. Buffer tanks made of chrome-nickel alloy
steel can be used for both purposes. Combined buffer tanks have built-in coil
from chrome-nickel steel, which is designed to provide DHW.
TECHNICAL DESCRIPTION
The buffer tanks with storage capacities up to 120 litres (capacity ranges 60,
80 and 120) may either be mounted vertically or horizontally on hinges on the
wall of the premises, or be Zlaced in a vertical position on the room floor.
Buffer tanks by ranges 150-2000 are exclusive of standing type – they may be
mounted only on the room floor. The tanks by ranges 80-120 are provided with
outer steel shell with epoxy coating and insulation of moulded polyurethane
foam. The tanks by ranges 150-300 are delivered with heat insulation of hard
(molded) polyurethane (letter „K“ in model number). The tanks by ranges
500-1000 are delivered with heat insulation of hard (molded) polyurethane or
expanded polystyrene (EPS, letter „F“ in model number.). The tanks by ranges
1500-2000 are delivered with heat insulation of expanded polystyrene.
Enamelled water containers are provided with additional protection against
corrosion through embedded anodes made of suitable alloy. The water containers
without enamelled coating corrosion protection is secured by corrosion
inhibitors contained in the coolant heating system inhibitors. The corrosion
inhibitors are specifically indicated in the installation instructions by the
company responsible for the selection and production of the inhibitors
contained in each specific buffer storage tank. The buffer tanks made of
chrome-nickel steel are identified by the letter H in their model
denomination. Modifications of the buffer storage tanks with built-in one or
two heat exchangers are correspondingly marked with additional letters S or S2
in their model denomination. Combined buffer tanks are marked with “W” in
model number. They may be have up to two additional heat exchangers for
connection with heating system. Combined buffer tanks have no internal
protective coating. The exact and complete model number, nominal operating
parameters and serial number of purchased buffer tank are
marked on manufacturer plate affixed on its body. The water used in DHW
dedicated buffer storage tanks must comply with the regulations for domestic
water, in particular
concerning the chlorides content which must be below 250 mg/l and electric
conductivity which must be above 100 μS/cm and less than 2000 μS/cm for
enamelled buffer storage tanks and below 600 μS/cm for buffer tank vessels
made of chrome-nickel steel.
INSTALLATION AND CONNECTION
The buffer storage tanks may be installed only indoors on premises protected
from dripping and splashing water. The premises must be secured against
temperatures falling below 0 °C. The room floor must have a siphon plant
effluent or another device with the same purpose, which must absorb any leaked
liquid from the buffer storage tank during prevention or servicing works.
WARNING! The water supply/heating system feeding the buffer storage tanks
must be equipped with a suitable relief valve in order to secure that pressure
in the buffer storage tanks be constantly kept under the nominal operational
pressure. Between the buffer tank container and the relief valve, there must
be no stop valves.
Installation and connection of the buffer storage tank must be carried out
only by companies with business in the field of heating and air conditioning
equipment and in accordance with the design such companies produce.
IT IS PROHIBITED to install stop valves on the inlets and outlets of heat
exchangers simultaneously in cases where a backup immersion heater is
installed in the buffer vessel with heat exchangers.
Where the plumbing pipes are copper or of another metal, other than that of
the water tank, or where brass fasteners are used, it is recommended to
install on the buffer tank inlet and outlet nonmetallic couplings (dielectric
fittings). The buffer tank outlets that shall not be put into usage must be
properly blocked to ensure water tightness at an outgoing pressure of at least
twice the nominal of the concerned buffer vessel at the maximum operating
fluid temperature.
USAGE AND MAINTENANCE
The buffer storage tanks must be used only as part of the concerned water
supply or heating system. The requirements for its usage are listed in the
documentation provided to the consumer by the company that carried out the
system design, installation, and commissioning activities. Compliance is
absolutely mandatory!
The manufacturer reserves the right to make any further structural changes
that do not affect the buffer safety.
