page 8 of 106 General information Remove all packing material from the packing box. Re- NOTICE move the product from its packing-box and retain all pack- aging until the equipment is inspected and tested. Re- move the protective caps from the inlet and outlet ports and retain for future use.
page 9 of 106 + Do not use the pump to generate pressure. The pumps are designed for operation at ambient temper- NOTICE atures between +50°F and +104°F (+10°C and +40°C). Check the maximum temperatures if installing the pump in a cabinet or a housing.

page 11 of 106 necessary to avoid a reduction of ventilation. Do not place the pumping unit on soft surfaces (e.g., rub- ber foam) during operation. This may reduce or block the fans’ air supply. Keep a minimum distance of 8 in (20 cm) between the cooling fan and surrounding items (e.g., hous- ing, walls, etc.).
page 12 of 106 To the best of our knowledge the equipment is in compli- NOTICE ance with the requirements of the applicable EC-directives and harmonized standards (see ”Declaration of Conformi- ty”) with regard to design, type and model. Directive IEC 1010 (EN 61010-1) gives in detail the conditions under which the equipment can be operated safely (see also IP degree of protection, ”Technical data”, pg.
page 13 of 106 Do not pump substances which may form deposits in- NOTICE side the pump. The pumps are not suitable for pumping substances which may form deposits inside the pump. De- posits and condensate in the pump may lead to increased temperatures even to the point of exceeding the maximum permitted temperatures.
Page 14
page 14 of 106 + Never operate this pump if it has a damaged cord or plug. If the pump is not working properly, has been dropped or has fallen into water, contact your pump service provider. + Prevent any part of the human body from coming into contact with vacuum.

Secure hose connections at the pump appropriately, e.g., with hose clamps, to protect against accidental detach- ment. The VACUUBRAND controller CVC 3000 can only be oper- ated with components compatible with the VACUUBRAND VACUU•BUS system, (see ”Accessories”, pg. 79). The vacuum controller CVC 3000 controls VACUUBRAND diaphragm pumps NT and optional in-line, coolant, and venting valves.

page 33 of 106 + The isolation cover protects against glass splinters in case of breakage, acts as ther- mal isolation to avoid condensation of hu- midity and is intended to absorb shocks. + Never block the gas outlet ((2) hose nozzle for tubing I.D.
page 34 of 106 During operation + Vent and dispose of potentially dangerous gases or vapors at the outlet of the pump appropriately. • Due to the high compression ratio, the pump might gen- erate overpressure at the outlet. Check pressure com- patibility with system components (e.g., exhaust tubing or exhaust valve) at the outlet.

page 36 of 106 Important notes regarding the use of gas bal- last Gas ballast is a continuous purge to keep the pump’s in- terior as clean as possible and to reduce the possibility of condensation inside the pump. + Air and pumped media might react inside the pump or at the outlet of the pump and form hazardous or explo- sive mixtures, when you use air rather than inert gas for the gas ballast.
page 37 of 106 Important notes concerning the operation of the exhaust waste vapor condenser + Do never block the gas outlet ((2) hose nozzle for tub- ing I.D. 3/8” (10 mm)). The exhaust hose must always be unobstructed and pressureless to enable an unhin- dered discharge of gases.
Page 38
page 38 of 106 Permissible range of coolant temperature at the exhaust waste vapor condenser: 5 °F to 68 °F (-15°C to +20°C) Check hose connections prior to starting operation of the cooling system. Check coolant hoses regularly during operation. Removing the catchpots: Catchpot at outlet: Remove joint clip.
page 39 of 106 Shutdown & storage The pump can be switched off under vacuum. Short-term: NOTICE Has the pump been exposed to condensate? Allow the pump to continue to run at atmospheric pres- sure for a few minutes. Has the pump been exposed to media which may damage the pump materials or form deposits?
