4 Product range SolarBloC Solar stations Product range SolarBloC The PAW SolarBloCs are used to circulate the solar fluid in the solar circuit efficiently. Solutions in the dimensions DN 20 to DN 32, offer a broad application range up to 175 m² of collector surface. To obtain a maximum flexibility during system planning, PAW focuses on the two versions Basic and Premium for its SolarBloCs. The SolarBloC Basic is an inexpensive entry level version with functional features. In contrast, the SolarBloC Premium is fully equipped with additional temperature and flow rate sensors. Individual system requirements, such as heat quantity measurement and the operating modes high-flow and lowflow can be realised with the suitable SolarBloC and the optionally integrated controller. SolarBloC midi Premium The SolarBloCs use high-efficiency pumps, which offer an extremely broad adjustment range. Thus, the optional controller adjusts efficiently the pump speed to the required flow rates. Additionally, high-efficiency pumps save more than 50% of electrical driven energy compared to conventional asynchronous pumps. Furthermore, these pumps meet the energy efficiency guidelines (EuP / ErP READY) of The controller is delivered preset, mounted and prewired to guarantee an easy adjustment to the real system. For a safe and quick commissioning, the solar stations SolarBloC are equipped with pressure relief valves, ball valves as well as with fill and drain valves. The insulation meets the EnEV 2014 requirements. Application range of the solar stations: SolarBloC maxi Premium Depending on their operating mode, solar thermal systems are divided into high-flow and low-flow systems. High-flow-systems operate with litres per m² of collector surface and hour which corresponds to l / (m² x min). Low-flow-systems operate with litres per m² of collector surface and hour which corresponds to l / (m² x min). The flow rate which is circulated in the system depends on the operating mode, on the collector surface as well as on the performance of the heat exchanger (secondary). The dimensioning of the circulation pump depends on the flow rate and the pressure drops which occur in the heat exchanger, in the collector and in the piping system/valves and fittings of the system. The application ranges/collector surfaces are mentioned in the product description. The mentioned values refer to a pressure drop of about 3.5 m wc and the most powerful pump in the system (assumed pressure drops: 1.5 m wc in the collector, 1.5 m wc in the pipes and 0.5 m wc in the heat exchanger). A specific flow rate of 0.25 l / (m 2 x min) is assumed for low-flow systems, whereas 0.5 l / (m 2 x min) is assumed for high-flow systems. The values are only a first indication for the dimensioning. It is always essential to carry out a detailed dimensioning of the system! PAW-Dimensioning Low-Flow l / (m 2 x h) High-Flow l / (m 2 x h) 15 l / (m 2 x h) = 0.25 l (m 2 x min) 30 l / (m 2 x h) = 0.5 l (m 2 x min) SolarBloC mega /2016 Printed in Germany PAW GmbH & Co.

7 PAW replacement set for solar pumps The PAW solution for replacing solar pumps and changeover to high-efficiency technology Since August 2015, within the scope of the European Ecodesign directives for energy related products (811/2013 and 812/2013) to increase the energy efficiency, pumps with asynchronous motors must not be operated any longer in solar thermal installations. As already for heating technology established, solar stations must also be operated with high-efficiency pumps from now on. Controllers of old solar installations are usually incompatible with new high-efficiency technology. High-efficiency pumps require always constant mains voltage for operation, the speed control is effected via separate/additional control signals (0-10 V or PWM signal). Old controllers are not equipped with an appropriate control signal output. In the case that an existing (asynchronous) pump has to be exchanged without replacing the controller, PAW offers the PAW replacement set for solar pumps, consisting of: High-efficiency pump Pump signal converter (PSW)* Connection cables Gaskets The following table helps you to find the suitable replacement set for the solar station. *The pump signal converter converts the controlled 230 V alternating voltage such as control via pulse packages, phase angle or trailing-edge phase to a PWM or 0-10 V control signal. How to replace the pump Dismount the asynchronous pump and replace it with a high-efficiency pump. Connect the PSW to the controller (to the same relay to which the old pump was connected to). Connect the PSW to the pump plugs and plug the shock-proof plug into a socket. The PSW is correctly preset for the pump. Thus, complex solar installations can be continuously operated with the existing controller. Whether to replace a faulty asynchronous pump or to increase the efficiency of a installation: the PAW service team will assist you in the selection of a high-efficiency pump with appropriate characteristic curve. Replacement set for solar pumps in solar stations DN 20 (¾") DN 25 (1") DN 32 (1¼") Item no Grundfos UPM3 Solar Item no Grundfos Solar PML Item no Grundfos Solar PML What is the situation with domestic hot water installations? PAW domestic hot water modules are equipped with perfectly matched components such as heat exchanger, pumps, sensors and controllers. The pumps are usually designed as high-efficiency pumps. To ensure the usual temperature stability after replacing a component, please contact our service team and keep the serial number of the station ready. The serial number is placed in the lower right corner of the support sheet of the station. We will gladly submit you a specific recommendation for replacement. Prices excl.

34 General Terms and Conditions General Terms and Conditions PAW GmbH & Co. KG, Böcklerstr. 11 D Hameln - Germany (RA_SD/Vers ) 1. Scope The following General Terms and Conditions (GTC) apply to all goods and services rendered by PAW GmbH & Co. KG (referred to as PAW in the following). Deviations from the GTC are only binding for PAW if explicitly acknowledged by PAW in writing. For foreign business transactions, the definitions of INCOTERMS prevailing at the time of conclusion of the contract apply in addition to the GTC. 2. Conclusion of Contract/Quotes and Acceptance 1. The Customer is bound to orders (quotes) for four weeks upon receipt by PAW. Orders become legally binding only upon written order confirmation by PAW. Agreements, verbal or by telephone, can only form part of the contract if confirmed in writing by PAW. The same applies to orders per Internet or Cost estimates with drawings and other documentation given to the Customer by PAW prior to any contractual agreement, remain the property of PAW until signing of the contract and - if a contract is not concluded - must be returned to PAW upon request. PAW retains all copyrights pertaining to the documentation. Duplication and passing thereof to Third Parties requires advance consent by PAW. 3. Prices and Terms of Payment 1. Prices quoted are net ex works including packaging and excluding VAT (sales tax), freight and transport insurance, customs, postage and other transport costs. Deliveries within the EU market (Intra-trade) are exempt from VAT (sales tax) only if the Customer quotes his valid VAT ID number when placing the order with PAW. 2. If delivery periods in excess of three months are agreed upon, PAW is entitled to subsequently increase the prices for material and/or labour which formed the basis of the original cost estimate by an appropriate amount, if the increase in costs was not foreseeable at the time the contract was concluded. 3. Payment is due within 30 days from the date of invoice without any deductions. Bills of exchange and cheques are precluded. Receipt of payment determines on time payment. In case of delayed payment PAW has the right to charge interest on arrears at nine percent above the prevailing base rate. In the case of several outstanding accounts, PAW is entitled to freely determine the set-off against individual invoices. The Customer is given an appropriate set-off statement. 4. If, following written order confirmation, PAW receives knowledge of a significant deterioration in the assets of the Customer or if other justified doubts as to the creditworthiness of the Customer arise, PAW is entitled to make deliveries only against appropriate securities or pre-payment. 5. If the Customer is in default of payment, PAW can withhold further deliveries and services until all due receivables are balanced, unless the Customer pays in advance. 4. Delivery, Passing of Risk, Storage Costs 1. The transport of goods occurs at the risk of the Customer - even when the freight order was placed and paid for by PAW. Fixed delivery dates are only legally binding if contractually agreed or confirmed by PAW. Relevant for on time delivery is the time the goods were consigned to the carrier or other company handling the transport/ shipment. 2. If a delivery date is exceeded at the Customer s request or other reasons for which PAW is not responsible, the Customer bears the resulting storage costs, commencing 30 days after availability for dispatch. For storage on site, a flat-rate of 0.5% of the net invoice value is payable per month or 1/30th per calendar day respectively. The Customer is entitled to prove that PAW incurred considerably lower storage costs. 5. Reservation of Proprietary Rights 1. PAW retains the right to all supplied goods until complete payment of all invoices resulting from the business relation with the Customer. This also applies when the purchase price has been paid for certain goods specified by the Customer, as the reserved property acts as security against the overall receivables balance due to PAW. The processing of goods supplied by PAW - and which are still retained as property of PAW - is always on behalf of PAW, without any commitments resulting therefrom for PAW. If the goods so retained by PAW are mixed or incorporated with/into other goods, the Customer herewith assigns his proprietary or co-proprietary rights on the new article to PAW and will store said articles with due diligence. The Customer may sell goods to which PAW has the proprietary rights under normal business transactions, as long as the Customer is not in arrears with payment. 2. Protective conveyance, pledging or selling of stock enbloc by the Customer to Third Parties is not permissible, in as far as the proprietary rights of PAW are affected. With conclusion of the purchase contract between the Customer and PAW the Customer assigns, as security, the full amount - not only the pro rata sum - of any claim due against a buyer resulting from a purchase or other legal reasons including all subsidiary rights. The Customer remains entitled to collect these claims as long as he is not in arrears to PAW. If the value of the object supplied under retention of title as a security interest exceeds the total receivables of PAW by more than 20 %, PAW shall be obliged to release the collateral to which it is entitled upon request by the customer insofar as the realizable value is secured by another collateral of equal value (e.g. bond). 3. If PAW takes back goods from the Customer without incurring any legal commitment this does not constitute a cancellation of the contract. In the case of such returns of goods PAW will issue the Customer with a credit note less compensatory handling charge of 20% of the net invoice value, with a minimum charge of Freight costs for the return of goods to PAW are to be paid for by the Customer. The Customer is entitled to prove that PAW incurred significantly lower costs /2016 Printed in Germany PAW GmbH & Co. KG D Hameln Germany Phone: Fax: info@paw.eu
