Pressure drop in tanks CTC Modul is series connected with a flange connection. The diagram shows the pressure drop in kPa in series connection depending on the flow and number of tanks connected in series (1–12). Important to remember regarding the flow through the tanks: The modules provide approx.
Pipe installation General This chapter is for the person responsible for one or more of the necessary installations. Take your time going through functions and settings with the property owner and answer any questions. Installation must be performed by a qualified professional. Water quality Important! The tanks must be flushed...
Installed on the incoming cold tap water line. Expansion vessel for cold tap water To avoid loss of overflow water (discharged during expansion of the water upon heating), an expansion vessel is installed in direct connection to the tanks' incoming cold tap water connection. The size of the vessel depends on the volume that has been selected in the system.
System options The module tank system is flexible and can be connected in different ways depending on needs and conditions. Some examples of connections are shown below. The system can be extended and adapted with an optional number of tanks as required. System 1 Connected heat pump with Legionella function 1 Storage module 400 L...

Function The example in system 1 shows 3x 400 L storage tanks (1) and 2x 400 E15 power modules (2) (alternatively, further power modules can be connected in series). A heat pump (with EcoLogic (25) control system) connected via a charge exchanger (6) (pre)heats the tap water in the storage modules. A sensor (23) is installed on the lower part of the first storage module to start and stop accumulation of hot tap water.

HWC function A separate timer for HWC starts and stops the circulation pump (C) at the times when HWC is desired. The mixing valve (15) is supplied with the cooling hot tap return water, and mixes the hot tank water to the desired temperature. A solenoid valve (B) does not need to be installed if the hot tap water increase function (Legionella protection function) is not installed.

Significant hot water requirement/installations If the hot water requirement is very high, it may be necessary to connect the system in series/parallel as shown in the figure below. This reduces the pressure drop in the system. Make sure to install valves that enable adjustment of equal flow between the series-connected rows.
Recommendations and design During design, consumption is calculated over a 3 hour period with the following intervals: 1–5 apartments 240 l/apartment 6–10 apartments 220 l/apartment 11–15 apartments 200 l/apartment 16–20 apartments 190 l/apartment 21–25 apartments 180 l/apartment 26–35 apartments 175 l/apartment 36–45 apartments 165 l/apartment More than 45 apartments...

Materials for connecting to 3x 5 kW are available in a supplementary Immersion heater 7.5 kW, CTC Modul 300/400 E15 package. The immersion heater consists of 3x 2.5 kW electrical heaters, which are switchable to 3x 5 kW. Installation, replacement and servicing of the product's immersion heater must be performed by a qualified electrical installer.
Commissioning Installation check Once installation is completed, review and tick off the items on the checklist (see section checklist). Flushing of tanks The corrosion resistance of the tanks must be ensured when the tanks enter service after the completed installation. The non-corrosive tanks are manufactured from high-quality stainless steel and, in order to achieve the best possible resistance against aggressive water, the tanks must be flushed with cold water before commissioning.
10. Operation and maintenance After installation Once the system has been installed, the user and installer must together check that the system is in full working order. Let the installer show you where the power switches, controls, valves, fuses, safety vales etc. are so that you know how the system works and how it should be maintained.
11. Thermostat for immersion heater Operating temperature A combined operating/max thermostat is installed on the outer surface of the tank, close to the immersion heater. The thermostat controls the connection and disconnection of electrical power at the temperature that is set on the thermostat. Setting of the thermostat must be performed during electrical installation and must be performed/changed by a qualified electrical installer, as the space contains powered parts.
12. Troubleshooting and actions The list below presumes that the installation is correctly dimensioned and has been functioning from the start. Fault has occurred "suddenly". Measures that involve intervention in the product must be performed by a qualified installer/service technician. Symptom Probable/possible fault Info/action...
