Instructions VX Solo II

2.0 Safety notes

Instructions

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. The risk of persons being injured and equipment damaged increases considerably if the recommended permissible operating parameters are exceeded. Installation, assembly work, ﬁrst start-up and maintenance work may be carried out only by qualiﬁed and authorized personnel in compliance with the safety regulations (both heating and electrical work).

Connection

The substation must be equipped with features that ensure that the substation can be separated from all energy sources (also power supply).

Warning of hot surfaces

Parts of the substation may become hot and hot surfaces can cause serious burns. Please be extremely cautious in close proximi-ty to the substation.

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 only to operate with water or a water-glycol mixture (up to 40%), and other heating media may not be used. Connect the substation to the house installation in a frost-free room, where the temperature does not exceed 50 °C and the humidity does not exceed 80%. 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.

Corrosion protection

The maximum chloride compounds of the ﬂow medium should not be higher than 300 mg/l. The risk of equipment corrosion increases considerably if the recommended permissible chloride compounds are exceeded.

Safety valve(s)

We recommend mounting of safety valve(s), however, always in compliance with local regulations.

Sound level.

≤ 55 dB.

Warning of high pressure and high temperature

The stations work at a maximum supply temperature from the district heating network of 110°C and the stations work with a operating pressure of 16 bar, which may put the user at risk of burns from touching the surface or from the emissions of hot media (water/steam). The risk of persons being injured and equipment damaged increases considerably if the recommended permissible operating parameters are exceeded.

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.

Warning of transport damage

Before substation installation, please make sure that the substation has not been damaged during transport. Always transport the substation with the utmost care and caution.

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.

(Do not overstrain! - See item 7.2)

3.0 Storage and Handling

If the substation is stored before installation, make sure that the place is dry and heated. (Humidity max. 80% and storage temperature 5-70 °C).

Do not stack the unit higher than factory shipped. Units that are shipped in cardboard packaging are to be lifted by the carrying handles of the packaging. Transport / removals over great distances should be carried out on pallets. During and after unpacking, the substation can be lifted by using straps, ﬁtted around the pipes or it can be lifted by hand in the pipes Lifting in the pipes can cause leaks. ALWAYS re-tighten.

Handling

When working on the substation suitable safety shoes must be worn.

4.0 Disposal

Dispose of packaging material in accordance with local regulations. This product consists of materials, which must not be disposed of

together with domestic waste. Switch oﬀ the complete power supply and dismantle the product and sort the components in various groups before disposal. Always observe the disposal rules of the local legislation.

Instructions VX Solo II

7.0 Mounting

Necessary assembly, start-up and maintenance work must be performed by qualiﬁed and authorized personnel only, and always in compliance with local regulations and this instruction manual. The substation must be easily accessible, enabling maintenance work without undue discomfort. The substation is intended for wall mounting and the mounting sheet on the back of the substation has got holes for screw installation. Lift the substation in the back plate and ﬁx it to a solid wall, which has the necessary load-bearing capacity, in a workmanlike manner with two strong bolts, screws or expansion plugs. All pipes and connections must be cleaned and rinsed before startup. After that the strainers should be cleaned. A label for each of the diﬀerent connections is placed on the substation. Connect the substation to the household piping according to these symbols as well as the instructions in this manual.

7.1 Variable connection possibilities

The substations oﬀer variable connection possibilities (not VX Solo II HWS OP), as connection of pipes can be established in the top or in the bottom of the substation. Upon delivery the substation is prepared for connection in bottom of the substation. For change of connection from bottom to top, demount plugs on connection pipes in top of substation and ball valves on connection pipes in bottom of substation, and mount plugs in connection pipes in bottom of substation and ball valves on connection pipes in top of substation. Please note that the air screw, which originally is mounted on the heating supply pipe in top of substation must be relocated to the highest point of the substation.PLEASE NOTE that the variable con- nection possibilities makes it possible to establish some of the connections in the top and others in the bottom of the substation. This may be desirable in some cases.

7.2 Tightening of connections

Check and tighten all connections before adding water to the system, as vibrations during transport may have caused leaks. After having added water to the system, tighten all the connections before performing leak test. If the substation operates in accordance with the dimensioning basis, re-tighten the connections and take the substation into continuous use. Please note that the connections may be supplied with EPDM rubber gaskets - in general connection sizes from ¾” to and incl. 1½” for Kompakt H stations. Therefore take care not to overstrain the union nuts, as this may result in leaks. The manufacturer accepts no liability for leaks that result from overstrain of union nuts.

7.3 Expansion vessel

The VX Solo II substations are equipped with an expansion vessel, which is factory set to 0,5 bar.

Please note that for type HWS OP the expansion vessel is not part of the delivery.

Control of heating circuit

For controlling the heating circuit the VX Solo II HWP (ECL 210), AVPB-F is supplied with a 2-way valve VS 2 and an electrical actuator AMV 150, which in combination with the ECL controller controls the heating circuit.

The electrical actuator has undergone a functional test from factory. In case of operating disturbances the actuator can be closed manually turning the manual override knob on top of actuator counterclockwise.

Please see enclosed instructions, Electrical actuator AMV 150 2-way valve VS 2

Manual override (AMV)

Diﬀerential pressure controller

The self-acting diﬀerential pressure controller AVPB-F with ﬂow limitation reduces the ﬂuctuating pressure in the district heating network to a small and invariable operating pressure in the substation and thereby ensures the best possible operating conditions.

The control valve opens on falling diﬀerential pressure to maintain constant diﬀerential pressure, and closes on rising diﬀerential pressure or when set max. ﬂow is exceeded.

The diﬀerential pressure controller is preset from factory and should not be adjusted afterwards.

The controller has a control valve with adjustable ﬂow restrictor and ﬂow setting is being done by the adjustment of the ﬂow restrictor position.

The controller is equipped with excess pressure safety valve, which protects the actuator from too high diﬀerential pressure.

Please see enclosed instructions, AVPB-F

The temperature for the heating circuit is controlled by a Danfoss ECL 310 controller in combination with an electronic actuator. The ECL controller acts as the brain of the heating system. It lets you easily control and optimise system performance and operation. .

Please note: Your substation may look diﬀerent than the substation shown, as variants with other components may be supplied. Instructions for the ﬁtted components will always be supplied together with the substation.

Heating circuit

The temperature for the heating circuit is controlled electronically by the Danfoss ECL controller. The supply temperature ist calculated by the controller on basis of the outdoor temperature. The ECL Comfort 310 controller is loaded with a selected application by means of an ECL Application Key (Plug-&-Play). The Application Key contains information about application, languages and factory settings. From factory the VX Solo II H2WS is loaded with Application 1d. Other applications can, however, be loaded by means of the ECL Application Key, and it is possible to update the controller with new application software.

The controller is factory preset to turn oﬀ the heating automatically in the summer period.

The controller settings can be changed in accordance with the enclosed producer instructions for the mounted controller.

See ECL Application Key Box with ECL Comfort 210/310 user guide and mounting guide, for further information.

12.0 Circulation pumps

Grundfos Pumpe ALPHA2 L

Substation start-up / pump

Do not start the pump until the system has been ﬁlled with liquid and vented. The required minimum inlet pressure must be available at the pump inlet. See Grundfos instructions for the pump.

The heating system can be vented via an air escape valve installed above the pump.

The pump is self-venting. It need not be vented before start-up. Air in the pump may cause noise, This noise ceases after a few minutes running.

Please note, that the system cannot be vented through the pump Please note, that the pump must not run dry.

Pump setting

The pump is factory-set to start on the highest proportional-pressure curve PP2. This setting is suitable for a large majority of all single-family houses In this pump setting the pump performance and consequently the power consumption is adjusted according to hte heat demand in the system.

Grundfos Alpha2 L has seven optional settings, which can be selected with the push-button.

Enclosed photo shows the recommended and alternative pump settings for system types.

For further information about pump settings please refer to the enclosed Grundfos Instructions.

ALPHA2 L,

Installation and operating instructions

Summer operation

The circulation pump for heating is automatically switched oﬀ in periods without heat demand. To prevent the pump from blocking in periods without heat demand, the controller automatically switches on the pump for some minutes every third day. In this period the circulation pump should be set at the highest speed of rotation.

If the heating requirement increases the pump setting can be changed by means of the selector switch.

For more information about venting of pump etc. please refer to enclosed installation and operating instructions.

13.0 Maintenance

Maintenance work

Is only to be carried out by qualiﬁed and authorised personnel.

Inspection

The operator or other authorised personnel is obliged to perform inspections at regular intervals and if necessary carry out maintenance work according to these and other instructions. Within the scope of the above maintenance work all strainers should be cleaned, all connections should be tightened and the operation of the safety valves should be checked by turning the valve head in the indicated direction.

Rinsing/cleaning of plate heat exchanger

Brazed heat exchangers can be rinsed. For optimum cleaning the ﬂow rate should be a min. of 1.5 times normal ﬂow rate, preferably in backﬂush mode. This will remove any deposits formed on the inside of the plate heat exchanger. In case of more serious deposits, a cleaning liquid, approved by Danfoss (f.ex. Kaloxi or Radiner FI) can be pumped through the heat exchanger. Both are environmentally friendly cleaning ﬂuids and can be disposed of through the usual domestic sewerage system. Afterwards rinse thoroughly with large amounts of water.

Deacidiﬁcation of plate heat exchanger

After long operation, because of the relatively high temperatures in the plates or tubes, the heat exchangers are expecially subject to caliﬁcation. Any deacidiﬁcation of the plate heat exchanger is done as shown on the drawing to the right. For brazed plate heat exchangers weak inhibited acid solutions (e.g. 5% formic, acetic or phosphoric acid) may be used.

Measures after maintenance work

After maintenance work and before switching the system on again: – Check that all screwed connections are tight. – Check that all safety features, covers, that were removed, have been

replaced properly. – Clean the working area and remove any spilled materials. – Make sure that all tools, materials and other quipment that were

used, have been removed from the working area. – Connect to energy supply and check for leaks. – Vent the system. – If necessary adjust the system again. – Make sure that all safety features on the device and the system work

properly.

For the janitor or other supervisors Meter reading

It is recommended to read the heat meter at regular intervals, and to write down the meter readings.

Cooling / Return temperature reading

The cooling, i.e. the temperature diﬀerence between district heating supply and district heating return is of great importance for the total heat economy. It is therefore very important to observe the supply and return temperatures. Normal temperature diﬀerence is 30-35 °C. Please note, that the lowest district heating return temperature is directly dependent on the return temperature from the heating circuit and the cylinder circuit. Therefore, please observe these return temperatures.

Tightening of connections

When reading the heat meter, all ﬁttings and connections should be checked for leaks. If leaks are detected, contact qualiﬁed and authorized personnel immediately. Please note that the connections may be supplied with EPDM rubber gaskets - in general connection sizes from ¾” to and incl. 1½” for Kompakt H stations. Therefore take care not to overstrain the union nuts, as this may result in leaks. The manufacturer accepts no liability for leaks that result from overstrain of union nuts.
