Tubing Connections - Vertex PureWaterMachine 3C Owners & Installation Manual

2.9 Tubing Connections

a.
The model 3C-4.0 has the quick-connect "push-in" fittings. These fittings have
a collet to grip the tube and an "o" ring to provide the seal to the tubing. The col-
let has steel teeth in it to grasp the tubing to prevent it from backing out.
b.
Making a connection. To make a connection, first cut the tubing so it has a square
end. The tube must be clean and the surface smooth. Push the tube into the col-
let as far as it will go. See the diagrams below
Cut the tube square.
"O" Ring
Cut the tube square. It is essential that the outside diameter is free of score
marks and that burrs and sharp edges be removed before inserting into fitting
Insert tube
Fitting grips before it seals. Ensure tube is pushed into the tube stop
c.
Disconnecting
Push in collet and remove tube
To disconnect ensure the system is depressurized before removing fitting.
Push in collet squarely against face of fitting. With the collect held in this
position, the tube can be removed. The fitting can then be re-used.
d. Feed Water Line
Connect the orange colored 1/4" inlet tubing to the ball valve installed in step 2.4
above. To connect, remove compression nut and ferrule and slide on to tube. Insert
tube over the ball valve tube as shown in Fig. 2. Slide nut over threads and tighten.
e. Drain Line
Find the black colored 1/4" tubing. Connect the tube to the drain saddle clamp
from step 2.5. Push tube into fitting about 1/2 inch. Tighten plastic nut.
f. Faucet Line
Find the push-on fitting that screws on the faucet. Thread onto the faucet stem.
Find the white colored 3/8" tubing and push the tube into the fitting until it stops.
g. Tank Line
Install the plastic ball valve on the storage tank. Find the yellow colored 3/8"
tubing. Connect the tube to the plastic ball valve on the tank. Push tube into fit-
ting until it stops. Turn the valve to the on position. The tank comes pre-charged
from the factory at 5-7 psi. Double check the pressure with a tire gage (the air
fitting is on the opposite end of the tank from the ball valve). If it is less than 5
psi add 2psi with a compressor or bicycle pump. Note: Putting more pressure
than 7 psi does not help to increase water flow through the faucet.

Push up to tube stop
Push the tube into the fitting, to the tube stop. The collet (gripper) has stain-
less steel teeth which hold the tube firmly in position while the "O" ring pro-
vides a permanent leak proof seal
Pull to check secure
Pull on the tube to check it is secure. It is good practice to test the system
prior to leaving site and/or before use.
