Installation

3.3 Fit the pump to the base assembly

We recommend that you fit the Acoustic Enclosure when you install your GV80 pump. Use the following procedure

and (where necessary) the instruction manual supplied with the GV80 pump:

1. Fill the pump with oil: refer to the GV80 manual.

2. Refer to Figure 2 detail A. Move the base assembly (5) close to where you will install the GV80 pump, then lower

the levelling feet (6) so that the base assembly is level, is supported by the levelling feet (not the castors).

3. Refer to detail B. Undo and remove the M8 bolt and washers (8) from each of the four vibration isolators (9) on

the base assembly.

4. Use suitable lifting equipment to lift the GV80 pump over the base assembly (5), with the pump-motor at the

same end of the assembly as the cable-gland (4): refer to the GV80 manual.

5. Lower the pump onto the base assembly (5), so that the fixing holes in the pump frame (1) align with the fixing

holes on the top of the vibration isolators (9), then use the bolts and washers removed in Step 3 to secure the

pump frame (1) to the vibration isolators.

6. Refer to detail C. Use the M6 nuts (12), plain washers (13) and shake-proof washers (11) to connect the earth

(ground) cable (3, connected to the base assembly) to the earth (ground) stud (2) on the GV80 pump frame (1).

7. Remove the lifting bolts from the pump.

8. Refer to Figure 3, detail C. Use two of the 1/2 inch tube inserts (6) to fit one of the lengths of 1/2 inch outside

diameter vinyl tube (7) between the GV pump outlet elbow (5) and the cooling-water outlet connector (8) on the

base assembly.

9. Use the other two 1/2 inch tube inserts (6) to fit the other length of 1/2 inch outside diameter vinyl tube (7)

between the GV pump inlet banjo fitting (14) and the cooling-water inlet connector (9) on the base assembly.
