Troubleshooting FAQs

• Why does the gas booster belt keep coming off?

  The most likely cause is the pulley is not aligned.

• Why is our gas booster tripping on low inlet pressure?

  If you gas booster is regularly going out on low inlet pressure then you may have an insufficient supply to the booster. The inlet pressure switch is set at 12.5mbar, if the pressure drops below this the booster will cut out and need to be manually reset.

• How do we reset our booster when it has cut out on low inlet pressure?

  On the inlet pressure switch there is a red button. This needs to be manually pressed whenever a gas booster goes out on low inlet pressure. This is a safety setting that all gas boosters must have.

• Is there a way to overcome low inlet pressure without requesting more from the supplier?

  We do supply gas reservoirs which are installed before the gas booster and allow for a build up of gas to be kept before the booster should it be required when there is more demand, or the booster is starting up and the pressure may be low.

• Low inlet pressure on changeover of duty and standby system.

  The inverter driven system can help reduce this with delayed ramp up speeds. We do also supply gas reservoirs which are installed before the gas booster and allow for a build-up of gas to be kept before the booster should it be required when there is more demand, or the booster is starting up and the pressure may be low.

• Why has the Low outlet pressure light come on?

  The belt has potentially come off. Although the booster may sound like it is running, you will need to remove the outer belt guard to check the belt.

• We have too much pressure at the appliance. How can we restrict the booster?

  Governers should be installed on the appliances but also the Secomak APS system can help regulate the pressure. The APS is not a failsafe for the appliances however, and this should be raised with the manufacturer of the appliances.

• Why does the Gas booster sounds like it is hunting?

  This is uncommon but can happen with the bigger boosters in the range. It is where the booster is trying to maintain a pressure with an irregular flow and the inverter can struggle to regulate itself. This can be resolved with a call out from a Secomak controls engineer to regulate the booster.

• We are witnessing pressure loss through NRV and flexibles.

  This should be calculated before purchase of a gas booster. Secomak can provide charts to measure this based on requirements. It is expected that losses will occur through ancillaries and it will largely depend on the flow rate within the system.

• After maintenance we have found the belt alignment is not correct.

  This can sometimes be out when changing the belt over and it is a case of adjusting the motor manually and then running the pulley by hand to check alignment.

• The duty and standby system is not switching over.

  The first thing to check is if there are any lights illuminated. Sometimes if the booster has switched over because of an issue it will continue to run on the one booster until the fault is cleared. Failing this, give Secomak a call to discuss further.
