USER MANUAL WSI 110TU DIMPLEX

1 Assembly, installation and safety instructions Fig. 1.1: Layout Layout: Apart from position 1, all components numbered in the drawing form part of the DC intermediate circuit. Position 1 is included in the heat pump scope of supply. The drawing shown is a suggested integration, which may be de- viated from in practice due to conditions on-site. Components list:

NOTE The equipment for the DC intermediate circuit can be mounted inside or outside the building. Diffusion-tight insulation is required for installation in buildings. The circulating pump should be mounted as an assembly with the isolating valves as shown in the drawing. NOTE For design reasons, all high-efficiency pumps (in particular brine circulating pumps) must be mounted in a dry and frost-free place!GB-3 English

1.2 Screwed stainless steel plate

heat exchanger Requirements on the installation area: Sufficient space must be left free around the plate heat ex- changer for maintenance (replacing plates, tightening the pack- age). The free space should usually be around 1.5 to 2 x the width of the heat exchanger. Transport, lifting the plate heat exchanger: The heat exchanger is delivered screwed to a plate. The follow- ing points must be observed when lifting the device: Remove the fixing screws from the pallet. Attach a strap around a bolt on each side. Never use steel cables or chains! Lift the heat exchanger from the pallet, lower it horizontally onto its feet and position in its end position on solid ground, fix in place if necessary! ATTENTION! Never lift the heat exchanger by the connections or surrounding stud bolts! Always use the lifting lugs (if present) or lift on the top side of the front pallet. Fix the straps onto their bolts for this.GB-4 English

Installation of the pipe connections: ATTENTION! When connecting the pipe system to the heat exchanger, ensure that it is not subjected to stress or strain by the pipe system! Clean the pipeworkbefore installation on the heat exchanger!Heavy pipework must be supported to prevent strong forces frombeing applied on the heat exchanger.Use flexible connections to prevent vibrations on the heat ex-changer and to compensate for the expansion of the pipescaused by temperature fluctuations on the heat exchanger (ten-sion-free lengthways installation). NOTE To guarantee adequate venting, the bleeder valves should be mounted in the highest position in the flow direction of the medium (preferably on a pressure vessel). Isolating valves can be used on all connections of the heat exchanger to make them easier to open when necessary! Threaded pipe connections: During installation, ensure that these connections do not turnwhile pipe connectors or flanges are being mounted.Turning the threaded pipe connections could damage the seal inthe heat exchanger, which acts as a seal against the rear side ofthe pipe connection! Flange connections: If the connection is lined with rubber, the lining also acts as aflange seal. The connection flange should be connected directlyto the end plate using the designated tapped holes. The screwsshould be tightened evenly - do not tighten excessively, as thiscould overwind the threads cut in to the frame plate.If loose support flanges are mounted on the heat exchanger, asuitable seal is required for sealing the flange. Commissioning: ATTENTION! Start the cold circuit first, followed by the hot circuit.Purge the system completely by closing the isolating valves be-tween the pump and the heat exchanger (if a valve is installed inthe return of the heat exchanger, open it).Then start the brine circulating pump and open the valves in theflow to the heat exchanger gradually.If necessary, purge again and repeat the above steps for the sec-ondary circuit if this is also a closed circuit.

and flow rate switch (FS) Pipe-mounted thermostat RAT 060I (frost protection): ATTENTION! In order to ensure fault-free functioning of the device(s), the instructions given in the following text must be observed. No temperature stratification must occur in the pipework at the installation site. The surface of the pipe must be bare at the installation site and any paint or other insulation must be removed. The tightening strap provided is inserted through the sensor base and pulled tight on the pipework. Excess lengths can be cut off. The strap-on sensor must lie tightly against the pipe (use heat transfer compound if necessary)! Switching function: If the temperature reaches or falls short of the set setpoint of 4 °C, the changeover contact switches from terminal P1 - 2 to P1 - 1. If the temperature exceeds the setpoint by approx. 4 K, the changeover contact switches back again Pump Terminal SignalM 16 J4/Y3 - X3 GND 0 - 10 VM 11 intermediate circuit pump J4/Y4 - X3 GND 0 - 10 VM 11 well pump Optional 3XPSSOXJP&RXSOLQJSOXJZZLWKPFDEOHEOXHZLUH±9*1'EURZQZLUH±9LQSXWEODFNZLUH±9RXWSXWQRWUHTXLUHG)L[LQJFOLSIRUSOXJFRQQHFWRU
