Installation
3.3 Unpack and inspect
Remove all packing materials and protective covers and check the pump. If the pump is damaged, notify your supplier
and the carrier in writing within three days; state the Item Number of the pump together with your order number
and your supplier’s invoice number. Retain all packing materials for inspection. Do not use the pump if it is damaged.
Check that your package contains the items listed in Tab le 2. If any of these items is missing, notify your supplier
within three days.
If the pump is not to be used immediately, replace the protective covers. Store the pump in suitable conditions, as
described in Section 6.
3.4 Locate the pump
The pump can be either free-standing on its baseplate which is fitted with rubber pads; fixed by four fixing bolt holes
in the baseplate; or used with vibration isolators. For the location of fixing holes in the baseplate, refer to Figure 2.
Provide a firm, level platform for the pump. Locate the pump so that the oil level sight-glass is visible and the oil
filler-plug, oil drain-plug, mode selector and gas-ballast control are accessible.
If the pump is part of a permanent installation you can remove the handle to make the pump more compact. To
remove the handle, cut the handle into two and remove the free portions from the pump.
3.5 Fill the pump with oil
Fill the pump with oil as described below. Refer to Figure 1 for the item numbers in brackets.
1. Remove the oil filler-plug (4).
2. Pour oil into the pump until the oil-level just reaches the MAX mark on the bezel at the top of the sight-glass (7).
If the oil-level goes above the MAX mark, remove the drain-plug (9) and drain the excess oil from the pump.
3. After a few minutes, recheck the oil-level. If the oil-level is now below the MAX mark, pour more oil into the
pump.
4. Refit the oil filler-plug. Tighten the plug firmly by hand. Do not overtighten.
