Gas Cylinder and Regulator Installation - Bench
Top and Under Counter Setups
Tightly connect a type 30 regulator (
or
) and ensure
the regulator pressure adjustment knob is turned completely counter clockwise to set the pressure
at 0psi. Push 8mm OD EVA Barrier tubing into the duotight fitting on the regulator and then push
this tubing into the gas inlet push in fitting on the Benchy Sparkling (outlet 1 in Figure 1).
IMPORTANT: After you have attached your Benchy Sparkling to your dispensing taps and
connected your Gas supply and mains water supply EVA Barrier hosing to the push in fittings on
the unit it is important to perform a leak test on the system. Failure to do so could result in your
CO2 cylinder emptying faster than expected or water leaks occurring.
Leak Testing - Bench Top and Under Counter Setups
It is essential to perform a pressure (leak) test prior to dispensing any sparkling or cold still water
from the Benchy Sparkling.
The Benchy Sparkling need to be pressure tested to a pressure that is at least 1.5 times the pressure
that will be used for dispensing. For example, if your dispensing pressure is 70 psi then the pressure
test should be conducted at around 100psi.
A pressure test can be conducted via multiple methods which are outlined below. It is a good idea to
perform both of the pressure test methods to be certain the system is holding pressure:
Pressure decay test
Step 1. Ensure mains water into the Benchy Sparkling is turned off, the regulator adjustment knob is
turned fully counter clockwise and the unit is connected too all dispensing taps.
Step 2. Set the pressure on the regulator to 1.5 times the dispensing pressure by turning the
adjustment knob on the regulator clockwise.
Step 3. Turn the gas cylinder off and leave to sit for a few hours (overnight is preferred). Then check
if the pressure on the regulator has decreased from the set pressure.
If the pressure has dropped then this indicates that there is a leak in the system. The source of this
leak needs to be determined and fixed before proceeding.
Bubble (Air-leak) test
Step 1. Ensure mains water into the Benchy Sparkling is turned off, the regulator adjustment knob is
turned fully counter clockwise and the unit is connected too all dispensing taps.
Step 2. Fill the reservoir with water until the cooling coils are submerged.
Step 3. Set the pressure on the regulator to 1.5 times the dispensing pressure by turning the
adjustment knob on the regulator clockwise.
