3.1.5 InLine Filter (Whale Aquasource WF1230)
● The InLine Filter is located beneath the kitchen sink on the cold feed to the tap, (this ensures drinking
water only is filtered extending the life of the filter).
● The Filter should be replaced every season.
● In winter months the filter should be drained by disconnecting the flexible pipe from the bottom of the
filter, release the s/s hose clip. (It should be left in this position until the system is reused again to
avoid frost damage).
i ▲ Never allow the pump to run dry. Always ensure the pump is submerged in the water or
the life of the pump will be reduced.
▲ Clean the water system at the start and end of the season with sterilising fluid (see notes
under sterilising).
▲ If the pump fails to deliver the most likely cause will be air in the system. To remedy this,
switch off the pump and shake the pump assembly in the water. Then switch on again.
3.1.6 Priming the System
● Place pump into the container, submerging
pump.
● Place pump plug assembly into inlet socket,
close lid ensuring plug assembly shoulder
locates into lid recess.
● Open all kitchen and bathroom taps to release
air from system.
● Close the yellow water heater drain-down tap
located next to the water heater unit.
● Switch on 12 volt supply at main panel
(isolator switch).
● Water will flow from open taps expelling any
trapped air within a few seconds.
● Turn off tap, the system is now ready for use.
▲ Care should be taken when turning on any of the hot taps after the water heater has been
switched on as steam can spurt from the tap whilst the hot water system is filling.
3.1.7 Pressure switch
Operation
The pressure switch detects the opening or closing of any tap in the system and switches the pump on
or off accordingly.
At normal flow rate the pump should operate continuously - but at low flow rates the pressure switch will
cycle on and off to maintain back pressure in the pipework.
