It is recommended that an indicator with a bypass setting of 7 psid is used with a non-bypass housing. Surge Control This optional feature is used to dampen pressure surges or spikes to avoid premature actuation of the indicator. Surge control delays the indicator response. Thermal Lockout Thermal Lockout (TL), prevents actuation below 6 F and allows actuation above 1 F system operating temperature. Its purpose is to avoid false actuations during periods of high fluid viscosity such as experienced during cold start. Dimensions: millimeter (inch) Donaldson Company, Inc. P.O.

Seal Kit Quality and Standardisation The development, manufacture and assembly of EPE-industrial filters and filter elements is carried out within the framework of a certified quality-management-system in accordance with DIN EN ISO 91. Certification of the filters by accredited institutions (for example TÜV, GL, LRS, LRIS, ABS, BV, DNV, DRIRE, UDT etc.) is available on request. The stability calculation and testing of the filters proceeds according to existing pressure vessel regulations, as well as in accordance with national and international norms. The CE identification mark according to the Pressure Equipment Directive 97/3/EG depends upon the individual application and operating conditions. On request we will classify the filters. 13 1 15 18 16 3 5 45 4 95 63 145 1 --- 45 4374 5

Mount the filter assembly using mounting device on the head Part 1 considering flow direction (direction arrows) and servicing height required for cleaning/replacing elements Part 3. Remove dust protection plugs from filter inlet and outlet, screw filter in pipeline without tension stress. Connection of Electrical Maintenance Indicator See brochure 64 and list according this brochure. Starting Put valve handle Part 1 in the central position to fill both filter sides. Switch on system pump. Ventilate filter by opening the valves Part 19/Part, close when operating liquid emerges. Put valve handle Part 1 in end stop for standard operation. Maintenance The filter element is clogged and needs to be replaced or cleaned when at the operating temperature the visual indicator s Part 17 red pin reaches its final position and/or the electrical switch is activated. Filter Element Service Open pressure-equalisation valve Part to equalise pressure in both filter housings. Switch change over valve on other side by moving lever Part 1. Close pressure-equalisation valve Part. Open the valves Part 19/Part on the filter taken out of operation and reduce the pressure. Unscrew filter bowl Part /Bottom Part 6 (only 45 LD 145 and 45 LDN 1) of filter bowl Part and remove filter element Part 3, turning slightly off its spigot in the filter head (Part1). Check filter Part inside and clean if necessary. Replace filter element H SL, P, VS and AS. The filter element with G media is cleanable. The efficiency of the cleaning process depends on the characteristics of contamination and the final pressure drop prior to servicing/cleaning the element. If the differential pressure after the filter element s cleaning process exeeds more than 5% of the pre service value the G element also needs to be replaced. Install cleaned or replaced filter element by slightly turning it back on its spigot. 5/45 LD 3 45 or 5/45 LDN 4 4: Check o-ring Part 5 on filter bowl Part, replace in case of damage or wear. 45 LD 95 145 or 45 LDN 63 1: Check o-ring Part 8 on filter bowl Part, replace in case of damage or wear.
