Installation
3.8 Connect to your emergency stop circuit
Note: If not connecting to own control equipment, the external EMS link plug supplied to the EMS connection on
the rear of the dry pumping system (Figure 3, item 22) must be fitted. Failure to do so will result in not
being able to operate the dry pumping system.
If required, customer’s own control equipment can be connected to the dry pumping system to shut it down in an
emergency using the EMS connection (Figure 3, item 22). The emergency stop control must be compliant with IEC
60947-5-1. (This should be a red self latching mushroom push button on a yellow background).
3.9 Connect and set up cooling water
Remove both the outer dust caps and inner plastic plugs from the water inlet and outlet fittings before
connecting the cooling water hoses.
Do not apply excessive torque to the water fittings when connecting the water supply to the dry pumping system
as this may cause damage to the manifold. Use a suitable spanner to prevent the bulkhead fittings on the dry
pumping system from turning whilst tightening up the connectors.
Fit the inlet strainer (supplied) into the supply side of the cooling water system to prevent damage to the cooling
system within the dry pumping system.
Notes: 1. For optimum water cooling, ensure that the cooling water supply meets the specification given in
Section 2.6. Ensure water supplies are connected in parallel. Refer to Figure 3, items 17 and 13.
2. For minimum water consumption, regulate the cooling water flow to the dry pumping system.
The dry pumping system is supplied with blue plastic dust caps fitted over the outside of the water inlet and outlet
fittings and with red plastic plugs fitted inside these water fittings. Ensure that both sets of plastic plugs are removed
before connecting the cooling water hoses, refer to Figure 12. Retain the plastic plugs for future use.
Do not turn on the cooling water supply until after completion of the electrical installation of the
dry pumping system or condensation may form inside the enclosure and there may be a risk of
electric shock.
