Installation Guide
Termix One-B
6.1.3 Strainer
Strainers should be cleaned regularly by authorized personnel. The
frequency of cleaning would depend on operating conditions and
the manufacturer’s instructions.
6.1.4 GTU Pressure Equalizer
The GTU Pressure Equalizer absorbs the expansion on the
secondary side of the Termix water heaters and can be used as a
substitute to the safety valve.
Furthermore the pressure equalizer absorbs a possible increase in
pressure, so a discharge outlet is omitted.
The GTU Pressure Equalizer may not be applied in systems with hot
water circulation.
6.2 Maintenance
The substation requires little monitoring, apart from routine
checks. It is recommended to read the energy meter at regular
intervals, and to write down the meter readings.
Regular inspections of the substation according to this Instruction
are recommended, which should include:
Strainers
Cleaning of strainers.
Meters
Checking of all operating parameters such as meter readings.
Temperatures
Checking of all temperatures, such as DH supply temperature and
DHW temperature.
Connections
Checking all connections for leakages.
Safety valves
The operation of the safety valves should be checked by turning
the valve head in the indicated direction.
Venting
Checking that the system is thoroughly vented.
Inspections should be carried out minimum every two years.
Spare parts can be ordered from Danfoss. Please ensure that any
enquiry includes the substation serial number.
Authorized personnel only
Assembly, start-up and maintenance work must be performed by
qualified and authorized personnel only.
