Maintenance; Troubleshooting - Honeywell VE300 Installation Instructions Manual

8. Start-up
8.1. Adjust softening
1. Measuring the water hardness with support from the total
hardness test-kit, included in the scope of delivery, the
water hardness should be measured before the installa-
tion.
Observe the information in the instruction manual of the
total hardness test-kit
2. Adjust heater water treatment unit (VE300) with blue
adjuster knob
• The suitable dilution setting (marker 0-3 on the casing
of the dilution unit, remove insulation lining if neces-
sary) is dependant on the regional water hardness and
the desired residual hardness. The value can be
extracted from the table attached to the cartridge.
8.2. Set to complete demineralisation
1. Measure the conductivity
• Before installation, an electrical conductivity meter
should be used to measure the conductivity.
2. Adjust heater water treatment unit (VE300) with blue
adjuster knob
• For complete demineralisation, the dilution must be set
to 0!
8.3. Filling up the system
1. Slowly open the ball valve on the inlet and outlet side of
the blending unit
2. After filling up the system, close the ball valves
3. Note the required parameters listed on the label of the
softening or complete demineralisation cartridge

9. Maintenance

Maintenance, service and repair work may be carried
out only by authorised technicians.
9.1. Maintenance
We recommend a planned maintenance contract with
an installation company
In accordance with DIN EN 1717 a regular maintenance must
be taken.
Frequency: every 1-3 years (depending on local opera-
ting conditions)
To be carried out by an installation company

11. Troubleshooting

Problem
No or too small water flow rate
MU1H-1547GE23 R0712

Cause
Ball valves up- or downstream of refilling combi-
nation are not fully open

9.1.1. Changing the softening or complete demineralisa-
tion cartridge
When the filling level of the heating system exceeds the
specified capacity, a cartridge exchange has to be
performed.
To determine the maximum capacity of the cartridge,
refer to EBA-P300L or EBA-P300LES
For softening:
The maximum capacity is determined according to the
total water hardness and the dilution setting.
The capacity is noted on a table included in the scope of
delivery, as well as the respectively added amounts of
water. If the filling level exceeds the noted water flow
meter end value, a cartridge exchange has to be
performed.
An exchange of the softening cartridge is recommended
at least 12 months after its first usage due to technical
safety purposes.
For complete demineralisation
The maximum capacity is determined according to the
conductivity and the dilution setting.
The capacity is noted on a table included in the scope of
delivery, as well as the respectively added amounts of
water. If the filling level exceeds the noted water flow
meter end value, a cartridge exchange has to be
performed.
An exchange of the demineralisation cartridge is recom-
mended at least 12 months after its first usage due to
technical safety purposes.
1. Close the ball valve on the inlet and outlet side of the blen-
ding unit
2. Decompress the outlet side by opening the sampling
valve (air bleed valve of the heater water treatment unit)
3. Unscrew the cartridge from the heater water treatment
unit
4. Screw the new cartridge in manually
5. Open ball valves on the inlet and outlet side
10. Disposal
• Dezincification-resistant brass housing
• Mechanical components of the heater water treatment unit
made of high-quality plastic
• EPDM sealing washers
Observe the local requirements regarding correct waste
recycling/disposal!
Remedy
Open ball valves entirely
