11. Place the valve flange clamps in place and checking the alignment of the
ports, tighten firmly (by hand).
12. Apply Teflon tape to the thread on the pressure gauge and screw into the
multiport valve body.
13. Complete all plumbing connections using the barrel unions provided on the
WATERMAID® sand filter multiport valve.
14. Pump Installation - Follow the pump manufacturer’s instructions.
CAUTION
On installation, where the waste line is more than 3 metres below pool water
level and more than 12 metres in length, a vacuum break should be fitted in the
waste line close to the filter.
If an auxiliary pump is installed inline downstream of the filter, it should be
protected against causing negative pressure in the filter tank. A flow or pressure
switch which only enables the auxiliary pump to run when main filter pump is
running will achieve this.
If the pump and filter are located below pool water level, it is necessary to fit
isolating valves in the pipe between the pump and the skimmer box and in the
return pipe from the multiport valve to the pool. This prevents water draining
from the pool during maintenance.
PIPE CONNECTIONS
Use Teflon tape on all male threads (at least two layers). Tighten the fitting by
hand first and then not more than an additional 1 to 1½ turns with a wrench.
Piping should be independently supported and not impose heavy loads on the
filter or pump. Use 40 or 50mm (1½ or 2") pipe from the pump to the skimmer
box, return pipe from the multiport valve to the pool and from the multiport valve
to the drain. 40 or 50mm flexible hose may be used with the WATERMAID® sand
filter with the use of suitable adaptors (not supplied).
40/50mm barrel unions are provided at the multiport valve for connection of
P.V.C pipe to 'pump', 'pool return' and 'waste'.
NOTE: ENSURE PIPEWORK IS CONNECTED TO APPROPRIATELY LABELLED
MULTIPORT VALVE CONNECTIONS.
