2. When detecting the filter capacitor in the power supply, the positive and negative electrodes of the electrolytic capacitor should be short-circuited first, and the short-circuit line should not be used to discharge the capacitor instead of the lead wire, because it is easy to blow the core wire. It is possible to take a 220V, 60 to 100W lamp with a cap lead, which is connected to both ends of the capacitor. The lamp will flash at the moment of discharge.
3. When troubleshooting a meter in a wet environment, it is necessary to measure whether the various points on the printed circuit are unobstructed, because the main fault in this case is corrosion of the copper foil.
4. When the internal circuit of the instrument is repaired, if the contacts and the circuit board of the mounting component are coated with insulating varnish, the parameters of each point can be measured by using an ordinary hand-sewn welding needle on the surface of the multimeter to directly measure the points by piercing the paint layer. There is no need to peel off the paint layer.
5. Do not hot plug various control boards and plugs. Because in the case of power-up, the plug-in control board will generate a strong induced electromotive force, then instantaneous counterattack voltage is very high, it is easy to damage the corresponding control board and plug.
6, do not blindly knock overhaul during maintenance, so as not to expand the fault, the more repair and more bad. Side-mounted magnetic flap level gauge 7, when disassembling, adjusting the instrument, should record the original position in order to restore.
8. When repairing precision instruments and meters, if you inadvertently fly a small part, you should first determine where it may fly, and do not look east. If you turn it west, you can use magnet scanning and line-of-sight scanning methods.
Applications:
Outdoor wood boiler domestic hot water tie in Boiler tie into domestic hot water
Solar thermal heat dump to domestic hot water
The Fin Enhanced side arm heat exchanger, using a fin design adds more surface area giving us an surface area five to eight times larger than traditional tube & shell side arms.
Fin Enhanced Advantages:
Highly Efficient Better Heat Transfer
Takes up less space due to compact design Faster recovery time
Made from stainless steel
As the Domestic Water is being heated, it is being drawn up the center of the water to water heat exchanger by convection, Both fluids are exchanger heat in separate chambers insuring that the two fluids do not mix This convection process is constantly working as long as the boiler system is circulating the preheated water through the jacket of the Side Arm heat exchanger.
By applying the fin shower save the cold water going to the water heater and the shower's mixer tap will be preheated. The water heater needs to work less then half of it's capacity during a shower. For dwellings savings over 200m³ gas a year can be achieved.
The fin sidearm shower save can be used in dwellings that have the shower on the first floor.
Besides dwellings the Fin sidearm shower save can also be used in hotels, apartments, nursing homes, swimming pools, hospitals, industrial applications, etc.
