Operating Guide Termix BL-FI
Instantaneous water heater with heat exchanger and automatic controls. Designed for wall-mounting.
Application
The Termix BL-FI substation is an instantaneous water heater featuring superb heat extraction and high performance. The substation is delivered with automatic controls prepared for a charging system.
The Termix BL-FI is suitable for large apartment houses, sports arenas and schools, where large amounts of hot water are needed.
Domestic hot water (DHW)
The substation is fitted with an efficient plate heat exchanger, which ensures the most favourable heat extraction and achieves optimum comfort and operating economy.
The Termix BL-FI charging system is delivered with Danfoss automatic controls for regulation of the charging temperature and the temperature in the hot water buffer tank. The control valve with integrated pressure control helps to avoid cyclic variations of the differential pressure in the district heating supply.
Domestic hot water circulation
The Termix BL-FI substation is supplied with connections for DHW circulation including circulation pump and a nonreturn valve as a standard.
Flexible solution
Pipe connection can be made from either the top or bottom, which makes this solution highly flexible. At the same time, both space and time are saved when installing.
Minimal heat loss
Complete insulation of the unit ensures minimal heat loss.
Reliable and easy to install
Termix BL-FI is operationally reliable. A quality product manufactured in Denmark, which is easy to install and quickly commissioned.

Operating Guide Termix BL-FI
The following instructions refer to the standard design of substation. Special versions of substations are available on request.
This operating manual should be read carefully before installation and start-up of the substation. The manufacturer accepts no liability for damage or faults that result from non-compliance with the operating manual. Please read and follow all the instructions carefully to prevent accidents, injury and damage to property. Assembly, start-up and maintenance work must be performed by qualified and authorized personnel only.
Please comply with the instructions issued by the system manufacturer or system operator.
Corrosion protection
All pipes and components are made of stainless steel and brass. The maximum chloride compounds of the flow medium should not be higher than 150 mg/l.
The risk of equipment corrosion increases considerably if the recommended level of permissible chloride compounds is exceeded.
Energy source
The substation is designed for district heating as the primary source of energy. However, also other energy sources can be used where the operating conditions allow it and always are comparable to district heating.
Application
The substation is designed to be connected to the house installation in a frost-free room, where the temperature does not exceed 50 °C and the humidity does not exceed 60%. Do not cover or wall up the substation or in any other way block the entrance to the station.
Choice of material
Choice of materials always in compliance with local legislation.
Safety valve(s)
We recommend mounting of safety valve(s), however, always in compliance with local regulations.
Connection
The substation must be equipped with features that ensure that the substation can be separated from all energy sources (also power supply).
Emergency
In case of danger or accidents - fire, leaks or other dangerous circumstances - interrupt all energy sources to the station if possible, and seek expert help.
In case of discoloured or bad-smelling domestic hot water, close all shut-off valves on the substation, inform the operating personnel and call for expert help immediately.
REACH
All Danfoss A/S products fulfill the requirements in REACH. One of the obligations in REACH is to inform customers about presence of Candidate list substances if any, we hereby inform you about one substance on the candidate list: The product
contains brass parts which contains lead (CAS no: 7439-92-1) in a concentration above 0.1% w/w.
Storage
Any storage of the substation which may be necessary prior to installation should be in conditions which are dry and heated.
Authorized personnel only
Assembly, start-up and maintenance work must be performed by qualified and authorized personnel only.
Please observe instructions carefully
To avoid injury to persons and damage to the device, it is absolutely necessary to read and observe these instructions carefully.
Warning of high pressure and temperature
Be aware of the installation’s permissible system pressure and temperature.
The maximum temperature of the flow medium in the substation is 110 °C.
The maximum operating pressure of the substation is 16 bar.
The risk of persons being injured and equipment damaged increases considerably if the recommended permissible operating parameters are exceeded.
The substation installation must be equipped with safety valves, however, always in accordance with local regulations.
Warning of hot surface
The substation has got hot surfaces, which can cause skin burns. Please be extremely cautious in close proximity to the substation.
Power failure can result in the motor valves being stuck in open position. The surfaces of the substation can get hot, which can cause skin burns. The ball valves on district heating supply and return should be closed.
Warning of transport damage
Before substation installation, please make sure that the substation has not been damaged during transport.
IMPORTANT - Tightening of connections
Due to vibrations during transport all flange connections, screw joints and electrical clamp and screw connections must be checked and tightened before water is added to the system. After water has been added to the system and the system has been put into operation, re-tighten ALL connections.

Installation must be in compliance with local standards and regulations.
District heating (DH) - In the following sections, DH refers to the heat source which supplies the substations. A variety of energy sources, such as oil, gas or solar power, could be used as the primary supply to Danfoss substations. For the sake of simplicity, DH can be taken to mean the primary supply.
Connections:
1.District heating (DH) supply
2.District heating (DH) return
3.Domestic hot water (DHW)
4.Domestic cold water (DCW)
5.Hot water circulation (HWC)
