Step 1: Remove the tank and riser tube assembly from the carton and make sure the
softener tank is empty and clean.
Step 2: Cover the distributor pipe with a clean rag or plastic so that NO gravel or media
enters the distributor pipe.
Step 3: Load the media - Refer Media Placement instructions.
a) Pour in the underbed gravel (No.6). Refer Table 1. 40kg.
b) Level out the underbed gravel using a broom handle/PVC pipe. The underbed
gravel should cover the bottom distributor by about 25mm.
CAUTION:
Do not raise the distributor pipe. If gravel is allowed to get under the
distributor, empty and start again.
c) After loading and levelling the No. 6 Gravel underbed, place the media in the
tank in the correct order which is D1, D2, 7M Sand, and D3.
¬
Slowly fill the tank .
Step 4: To obtain optimum performance from your unit, exercise particular care in
ensuring that each grade of media is levelled evenly over the previous layer.
Step 5: Fill the tank with water to 50mm from the top.
Step 6: Clean top of tank (neck & threads) of all traces of media. Remove the rag or
plastic fitted in Step 2, taking care not to raise the riser pipe.
Step 7: Unpack the valve, remove the cap screws and separate the adaptor. Store gasket
safely. Check that the tank thread ‘O’ ring and the internal Riser Pipe "O" ring
seals are in place. Using a little silicone “O” ring lubricant, lubricate the outer seal
surfaces only.
Step 8:
Fit the adaptor to the tank, carefully, to allow the distributor pipe to locate
centrally. Screw down firmly by hand. Do not over tighten. Place the gasket on
the tank adaptor, fit the valve body with cap screws provided. Tighten cap screws
evenly.
