3.6 COOLING WATER CONNECTION
Supply and drain connections are made through a transparent blue plastic
hose.
Check if the following characteristics are true:
-Highest pressure:
2 Kg./cm
2
-Lowest pressure:
1.5 Kg./cm
2
-Flow: 40 - 60 L/h. (s. temperatura)
The pressure must be within these limits. A pressure lower than 1 Kg./cm
2
can
cause working problems.
When first using the machine, clean the pipes properly before making water
pass through the circuit in order to eliminate remains from the assembly process.
We recommend to install an inlet purifier in order to filter the biggest impurities.
If water is rich in lime, you will have to install a water softener.
If inlet cooling water temperature is over 15º C, we recommend you to install a
water softener.
An alternative to the water softener could be a closed circuit.
3.7 GAS CONNECTION
For moulds designed for gas injection only.
The gas or gas mixture is usually supplied in high pressure bottles in which
outlet a pressure gauge is placed which regulates the outlet pressure of the gas. The
normal working pressure varies depending on gas volume (0.5-2 Kg/cm2).
In the free part of the pressure gauge, a flexible hose is placed (ref. RYLSOL
OX 20 Atm. dia. 8x16 mm.) which reaches the gas connection at the machine (see
connection diagram).
In case you needed so, the mixture could be made “in situ” with as many bottles
as components there are in the mixture. You will find in the market some mixers to do
this and even bottles with the mixture already made.
