AIR-VAC - HT138 - E-Stop Inspection for the AIR-VAC ElectricsEnsure you have a clean rag to wipe the dipstick.
1. Check the engine oil level before starting or more than 5 minutes after stopping the engine.
2. Remove the oil level gauge, wipe it clean and reinstall.
3. Take the oil level gauge out again and check the oil level.
CAUTION
To avoid personal injury:
Always wear correct PPE when operating the AIR-VAC
Recognition of radio identification code of the portable control unit (Rc400 G2B)
In the RC400 radio remote controls, the portable control unit works with the linked central unit in radio mode through a unique identification code. When a portable control unit (or a central unit) is replaced, it’s required to update this code to ensure that the system works again. The portable control unit connected with the serial cable works always (the identification code is ignored).
Recognition procedure:
Note: if a graphic display is installed on the portable control unit, after the second power on, it can take even one or two minutes to load the display configuration. Meanwhile, on the display, some messages will inform of the work in progress. The display inside the receiver will show a rotating segment until the process has finished.
When the display configuration has been completely transferred the display inside the receiver will show “1-“ (or “1P”).
Applicable to AIR-VAC Serial No. 002 onwards
When the Portable Control Unit (PCU) inclination exceeds the safety limit, the PCU internal buzzer
is activated (Tilt sensor pre-alarm signal); if the PCU inclination exceeds the safety limit for more than 2 seconds, all functions are disabled by the external MC2M controller.
Reset the remote.
Has the battery lost charge?
There are two (2) bearing in the door hinges, which needs to be greased every month. To do so, find the grease nipples under the hinges then connect the grease gun and add grease till you see it squeezing through the hole next to the grease nipple of from the top of the bearing housing.
To avoid the blower / air induction bars mounted within the chamber bending / warping, ash should be removed before it blocks the holes. If the ash covers the blower bars, air stops cooling them down, causing overheating and bending / warping. Ash can be pushed away from the blower bars when loading and when ash deposits become excessive, they should be completely scrapped out.
If the blower bars begin to bend / warp, as a temporary measure they can be rotated and put in upside down. Side bars can be swapped either side of the boiler.
As the blower bars are performing in a very aggressive environment, i.e., the main loading area and subjected to extreme temperatures. These parts will eventually need to be replaced. The guidance above will help to extend the blower bars lifetime. Replacement parts are available at GlenFarrow UK Ltd.
The shunt pump and flow switch are located within the large grey box attached to the rear of the biomass boiler.
The shut pump should have a permanent electrical supply and be continually operating to circulate water around the water filled door. The flow switch monitors the operation of the shunt pump to check for a continuous circulation of water around the front door. Should there be no circulation of water around the front door, the flow switch will stop the main fan in order to prevent the biomass boiler from overheating.
The Biomass Boiler and heating equipment are not frost protected. The boiler and the system should be drained if not used during the cold weather. For larger systems, which include several buildings, separate sections should be drained if not in use.
Before draining the Boiler, the cold main should be isolated.
Systems with open vent and the header tank, boiler feed from the header tank should be left on in order to drain the header tank as well. All the pumps have to be switched off before starting to drain the system. This can be done by switching on the main electrical supply on the boiler and switching the main circulator(s) isolators next to them if the circulators are fed from separate connection. On the sealed systems Mikrofill unit has to be switched off before starting to drain the system. This can be done by pressing ‘off’ button on the unit or switching off the switch next to the Mikrofill unit.
The Boiler can be drained through various drain points on the boiler (see Fig.1 on page 5). The door has to be drained separately from the boiler. Similar drain points can be found on every heating unit. The majority of the water within the system can be drained via the boiler, in order to avoid too much water being expelled within the premises heated.
Copper coils (log dryer coil, FCU’s etc.) have to be purged with compressed air stream, after the system is drained.
Note: If there is a plate heat exchanger (HE) installed on the system, the section after the HE needs to be drained separately.
Pressure Correct
The EDF continuously monitors the system pressure, when the system pressure is within the set parameters the unit will show ‘Pressure Correct’ on the LCD display
Filling stopped due to low mains water pressure
The EDF continuously monitors the inlet water pressure, if the pressure falls below an acceptable level then the unit will operate a safety shutdown. When water pressure is reinstated the unit will operate as normal.
High or low pressure alarms
If, for any reason, the system water pressure reaches a high or low condition; as determined be the set parameters, the EFD will show the alarm message, the relevant BMS relay will operate and the boiler/chillers relay will shut down the boiler or chiller (if connected). When the normal operating pressure is resumed the unit will automatically reset.
