1 Direct supply unit for heating systems 65 series ACCREDITED ISO 9 FM 65 CALEFFI 7/7 GB replaces dp 7/5 GB Function The direct supply unit performs the function of supplying the heating system circuits at high temperature. Complete with high-efficiency pump, flow and return temperature gauges on secondary circuit, secondary circuit shut-off valves, preformed shell insulation. The unit is reversible: in fact, the flow direction can be inverted from right to left, depending on installation requirements. This unit can be coupled to the 559 series SEPCOLL separator/distribution manifold with 5 mm centre distance connections. The differential by-pass valve (code 596) and mounting bracket (code65) are optional. Product range Code 656AL Direct supply unit. With UPM Auto L 5-7 pump.

4 Mounting bracket 65 Mounting bracket. In stainless steel. Hydraulic characteristics p (kpa) p (m w.g.) Setting positions Bracket installation The mounting bracket for wall installation must be secured using wall anchors, using the corresponding holes on the base. Flow rate (l/h) The unit should be applied to the bracket, using the corresponding seats under the hexagonal part of the shut-off valves. The hydraulic characteristics are calculated while taking account of the ball shut-off valves fitted. Installation of the differential by-pass valve To fit the differential by-pass, it should be applied in place of the by-pass spacer template. After shutting off the ball valves using the specific supplied spanner, unscrew the captive nuts as illustrated in the following figures. Differential by-pass 596 Differential by-pass for 65, 66 and 67 series units. Max. working pressure: bar. Max. working temperature: C. Setting range: kpa (, m w.g.). Connections M x M. Installation differs depending on the supply direction in the flow circuit: - by-pass installation in the version with RH side supply and bottom-up flow (equivalent to LH side supply and top-down flow); The differential by-pass valve is used to control the head to which the secondary distribution circuit is subjected. When the differential pressure setting value is reached, the obturator opens and allows the medium to pass from the flow to the return line of the circuit, limiting the differential pressure at the set value. This action is particularly useful when single circuits are shut off by automatic two-way ON/OFF, modulating or thermostatic valves. - by-pass installation in the version with LH side supply and bottom-up flow (equivalent to RH side supply and top-down flow).

5 Right hand-left hand reversibility The unit is assembled in the factory with RH side supply and bottom-up flow (equivalent to LH side supply and top-down flow). If necessary, the flow direction can be exchanged. For this reason, the nuts on the unit are not fully tightened in the factory, making it easier to carry out this procedure if required. We recommend always checking that the nuts have been fully tightened during installation. To make the exchange, proceed as follows:. Remove the insulation; the front and rear shells are easy to remove as they are slightly restrained to one another. In versions with UPML 5-95 pump, it is necessary to rotate the electronic part of the pump, unscrewing the four screws, as indicated by the arrows, and turning the body anticlockwise by 9. If this step is not performed, it will not be possible to fit the unit back inside the insulation. In AL versions with UPM Auto L pump no changes are required for the circulation pumps.. Reassemble the unit as indicated in the figure, fully tightening the captive nuts and taking care to position the seals in the correct way. 5. Invert the flow and return temperature gauges.. Unscrew the captive nuts fully using a spanner of the correct size and remove the pump. 6. Move the square spacer and fit it on the right-hand side. Note: The central notch in the insulation can be used to house the circulation pump and safety thermostat electrical wiring cables.. Position the connecting pipe on the right-hand side, rotating it on its axis by Reassemble the insulation.
