After connection of the heater to the eater mains, hot water heating system, el. network and after testing of the
pressure relief valve (according to the instructions that came with the valve), the heater can be set into
operation.
Procedure:
a) Check the water mains, electrical installation and in the case of combined heaters also the installation
for the hot water heating system. Check to the correct positioning of the sensors for the operational
thermostats. The sensors must be pushed all the way into the chamber as far as they will go.
b) Open the hot water valve on the mixer tap
c) Open the valve in the inlet pipe for cold water to the heater
d) As soon as water begins to spill out of the valve for hot water, filling of the heater is complete and the
valve should be closed
e) If any leak is apparent (the flange lid), we recommend you tighten the screws on the flange lid
f) Screw on the cover for the electrical equipment
g) When operating heating of utility water using heat energy from the hot water heating system, open the
valves at the inlet and outlet for heating water and if necessary vent the exchanger
h) On setting the heater into operation, flush out the heater until the cloudiness has disappeared.
11. CLEANING THE HEATER AND REPLACEMENT OF THE ANODE BAR
Through repeated heating of water, lime scale is deposited on the walls of the vessel and above all on the lid of
the flange.
The level of deposit is dependent on the hardness of the heated water, its temperature and on the amount of hot
water consumed.
We recommend a check and if necessary cleaning of the lime scale from the vessel after two years of
operation as well as replacement of the anode bar if necessary
. The life span of the anode is theoretically
calculated for two years of operation although this does vary depending on the hardness and chemical
composition of the water in the location where the heater is used. It is possible to determine the date for next
replacement of the anode bar on the basis of this inspection. Leave cleaning and exchange of the anode to a
company, which performs service work. When releasing water from the heater, the valve on the mixer tap for
hot water must be open so no low air pressure is created in the heater vessel, which would restrict the water
from escaping.
12. IMPORTANT NOTICE
-
The MG anode must be regularly checked and replaced
-
There must be no stop valve fitted between the heater and the pressure relief valve.
-
In the event of excess pressure in the water mains in excess of 0.6 MPa a reduction valve must be fitted
before the pressure relief valve.
-
All outlets for hot water must be fitted with mixer taps.
-
Before water is allowed into the heater for the first time, we recommend a check is made on the tightness of
the nuts on the flange joints of the vessel.
-
Any handling of the thermostat apart form setting of the temperature using the control dial is forbidden.
-
All work on the electrical equipment, setting and replacement of regulation elements must be performed by
a professional service business.
Disposal of packaging material
A service charge has been paid for the packaging in which the water heater
