3.8 Connect to the 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 must be fitted. Failure to do so
will result in not being able to operate the dry pumping system. Refer to
controls/connectors on the rear of the pump (system with rear exhaust and castors/
levelling feet
If required, customer's control equipment can be connected to the dry pumping system
to shut it down in an emergency using the EMS connection. The emergency stop control
must be compliant with IEC 60947-5-1. This should be a red self‑latching mushroom

3.9 Connect and set up the cooling water

WARNING:
Do not turn on the cooling water supply until the 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.
CAUTION:
Remove both the outer dust caps and inner plastic plugs from the water inlet and
outlet fittings before connecting the cooling water hoses.
CAUTION:
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
while tightening up the connectors.
CAUTION:
Fit the inlet strainer (supplied Y strainer) 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
