4. Switch on the electrical power to the dry pumping system. All the water valves in
the pump cooling system will automatically open for a period of around
10 seconds.
5. Adjust the water flow rate so that it meets the requirements given in
consumption data
close again after 10 seconds and the flow rate displayed by the water flow meter
will decrease (this is normal). If necessary, cycle the power to the pump to re‑open
the valves for a further 10 seconds to continue setting the water flow rate.
6. Once the water flow rate has been set the water flow meter may be removed.
7. Inspect the water hoses, pipelines and connections and check that there are no
leaks.
Turn off the water supply while completing the remainder of the installation procedures.

WARNING:
When fitting accessories inside the enclosure, ensure that the pump is switched off.
Lockout and tagout the electrical supply before removing the enclosure panels.
WARNING:
The surfaces of the dry pump, booster and spools are very hot when the dry pumping
system is running. Allow these surfaces to cool to safe temperatures before installing
the accessories inside the enclosure. Be sure to route and secure accessory cables as
shown in their installation manuals to prevent the cables from resting on hot
surfaces.
CAUTION:
The power to the dry pumping system must be switched off when the MCM
MicroTIM or active accessory module is installed or removed. If it is not, these
modules may be damaged. Refer to the appropriate accessory manual for more
information.
CAUTION:
The relays fitted in the MicroTIM are not suitable for switching inductive loads. If the
MicroTIM is connected to an inductive load (for example, a solenoid coil) then
suitable precautions should be taken. Fitting a flyback diode, of correct current and
voltage rating is recommended.
Refer to the individual accessories manuals for information about installation.
