TECHNICAL DESCRIPTION
The water heater is intended for domestic purposes in households, and can
provide hot water from the common water main system simultaneously for a
few consumers – kitchen, bathroom and etc.
The heated water should be correspond to the normative documents for
domestic water and, in particular: its chlorides composition should be less
than 250 mg/l and its electric conductivity should be more than 100 µS/cm,
while its pH within the limits of 6.5-8 for the water heaters with enameled
water tanks, and electric conductivity less than 200 µS/cm for the water
heaters with chrome-nickel steel water tanks. The water pressure in the
water supply system should be higher than 0.1 MPa and lower than 0.5
MPa. If the water pressure is higher than 0.5 MPa - please refer to the
instructions in the section for connection to the water supply network.
Special water heater models are in production (for regions where local
regulations require) with design to work in plumbing pressure up to 1 MPa.
The appliances water containers (water tanks) are properly protected
against corrosion by using high quality enameled coating, or are made of
high-range alloy chrome-nickel (corrosion resistant) steel. Water tanks with
enameled coating are equipped with built-in anodes made of special alloy
providing additional protection.
The outer casing of the appliances is made of epoxy-polymer coverage and
the heat insulation is made of CFC-free polyurethane foam.
Schematic views of the basic models with their modifications are shown in
Fig. 1, and technical specifications – in Tables 1. All figures and tables are
located at the beginning of this booklet.
The water heater models are marked with letters and digits as follow:
The first two letters and the following five digits indicate the device
base model.
xxx – the first three digits after the letters in the name TREND are
the code for the capacity range of the water heater.
"CERAMIC" - with a ceramic heating element, 1.5 kW for units of
volume group 50l and up to 2.2 kW for others.
The hot and cold water pipes are marked with colored pointers,
respectively red and blue.
The exact and complete model number, nominal operating parameters
and serial number of purchased water heater are marked on
manufacturer plate affixed on its body.
Water heaters for vertical installation.
These models of heaters are
designed for mounting
only
in a vertical position with cold and hot
water pipes downward, Fig. 1.
WATER HEATER INSTALLATION ON THE
WALL OF THE PREMISE
The water heater can be installed only in normal fire safeguarded
premises and where temperature cannot fall under 0 °C. The
availability of a siphon on the installation for waste waters as during
normal usage of the water heater, water may leak from the safety valve
aperture. At the same time the siphon will facilitate the water tank
maintenance, prevention and servicing operations when water needs to
be drained out of the water tank.
The type and nature of wall construction material, the appliance dimensions,
the way of fixing it, the location of its fixing elements and tubes, its protection
against dripping water must be taken into account when choosing the proper
place for installation. The protection against dripping water is marked on the
appliance production plate with its serial number. The appliance must be
mounted where it is protected against water dispersion or water pouring
over. In order to reduce heat loss it is recommended to keep minimum
distance between the heater and the places where the hot water is used.
If you purchased a water heater with factory-fitted power cord with plug, the
unit cannot be installed in a wet premise! The location of the device must
comply with the requirements for the electric installation and its contact.
Refer to the electrical connection of this instruction.
It is obligatory that there are spaces provided between the appliance and the
surrounding walls and the ceiling of the premise, as follow:
For vertical water heaters – at least 70 mm between the appliance and
the ceiling; at least 50 mm between the appliance and the side wall; at
least 350 mm below the appliance to facilitate servicing and possible
repair.
Water heater should be installed steadily on the wall of the premises. For this
purpose steel bolts (studs), tightly fixed in the wall, with diameter 10-12 mm
are used. The fixing elements should be secured against pulling aside the
wall – they should be anchor or passage bolts (depending of the wall
construction material). It is recommended that the elements on which the
heater will be suspended are designed for three times greater loads than the
appliance total weight and located in the water therein. Installation of the
water heater on decorative walls (made of single bricks or of other light
materials) is strictly forbidden. On Fig. 1 and in the tables are shown the
distances between the bolts (studs) for mounting the units.
Vertical water
heaters of 150 and 200 liters are equipped with special type of suspension
plates and correspondingly the distance between the bolts (studs) differs
from that of other models and modifications, please refer to Fig. 1.
WARNING!
The bearing plates of horizontal water heaters must be
securely clamped to the premise wall. Under the bolts heads (nuts on
studs) must be placed support washers!
Given the greater weight for water heaters of 150 and 200 liters there are
higher requirements for fixing to the premise wall and to the wall itself:
Given the wall type, material and strength, in order to provide secure
attachment for vertical water heaters it is necessary to build an
additional structure or to take adequate measures to strengthen an
existing one. Samples of such constructions are shown on Fig. 6 for
reinforced concrete wall thick 25 cm and more, and on Fig. 7 - for
brick wall and others materials.
WARNING!
Non observance of the requirements for fixing the water
heater on the wall may cause damages of the appliance, damages on
other appliances and the premises, where the device is located, as well
as corrosion of the casing or even more serious failures and damages. In
such cases eventual failures and damages are not a subject to
manufacturer and seller warranty liabilities and will be at the expense of
the party which has not observed the present manual instructions.
The water heater mounting to the premise wall must be completed only by a
specialist.
WATER HEATER CONNECTION TO THE WATER
SUPPLY NETWORK
The plumbing to which the water heater will be connected, as well as any other
elements included in it shall have to withstand sustained water temperatures
above 80°C and for short periods - above 100°C, as well as to pressure at least
twice high the appliance working pressure.
Upon connection of the water heater to the water supply grid, the arrows and
indication rings around the water heater pipes for hot and cold water must be
observed (inlet and outlet pipes). With an arrow towards the pipe
