Installing the Equipment
The equipment is supplied with the majority of the components already assembled.
Final assembly should be completed as follows.
1. Ensure that all packaging materials any other debris has been removed from
the equipment.
2. Situate the Frame (1) in the required location.
3. Adjust the height of the spray nozzles to position the tip of the nozzles
approximately 350 mm above the top rim of the sand tank. The nozzle
support frame (24) can be moved by withdraw the spring-loaded plunger (25)
at each end. One person at each end of the equipment should hold the nozzle
support frame while performing the adjustment. Re-insert the spring-loaded
plunger in the appropriate hole at each end ensuring that the nozzle support
frame remains parallel with the top edge of the sand tank.
4. Attach the level indicator (36) to the frame using the two fixings supplied.
5. Adjust the inclination of the sand tank to zero, shown by the level indicator
(36), using the scissor jacks (34) at the right hand end of the frame. The jacks
are operated by inserting the loose jack handle into the coupling (35). The
jack handle should be removed after adjusting the level of the sand tank.
Level the Frame by means of the four adjustable feet (3) located at each of
the framework legs. Use a spirit level (not supplied) on the top edge of the
sand tank (21) to determine the level and adjust the feet to level the sand tank
in both planes.
6. Ensure that the vertical mesh screen (30), sandwiched between two
perforated plates, is located in its support groove inside the outlet collecting
tank (28). Place the white plastic tank support in the recess at the end of the
frame with the tank locating pegs pointing upwards - below the weir
chute/diffuser (26). Locate the outlet collecting tank on the support ensuring
that it is positioned within the locating pegs.
If assembling the S12-MKII-50 then it will be necessary to connect the lead
from the pressure sensor on the side of the collecting tank to the connector
on the front of the electrical enclosure. Before use it will be necessary to
prime the tapping to the pressure sensor with water to ensure accurate
measurements. This procedure is described in the
Commissioning section.
