EXCHANGER SERVICE

"Can not provide enough temperature in radiators or fan-coils."

• Make sure that the connections of heat exchanger are true.
• Make sure that hot water or steam from boiler is being sent to heat exchanger
• Make sure that cooling heat exchanger group has sufficient amount and degree of water.
• If you have 3-way or 3-way proportional valve on the heat exchangers hot water supply line, make sure that valves are directly canalised from hot water to heat exchanger.
• Turn off the other valves on the collector, if hot water line is being fed from collector. Then canalise the hot water directly to heat exchanger.
• Make sure the pomps is working and suppliying enough flow rate.

"Heat exchanger leaking out water"

• Control the tighteening measure of between two outer body of the heat exchanger is not more than desciribted at front sticker. If there are differences , bring to a minimum distance between two bodies.

"Heat exchanger is not working as performed as first day"

• Due to the contamination, heat exchanger installation may have been collected and blokaged caused by dirt. Heat exchanger must be dissembled and must cleaned.
• Strainer in pipping may be clogged. Make sure the strainer is clean.
• Make sure that is there any change on capacity of pomps.
• Control that is condensate tank lower than the lowest point of heat exchanger. if not, please revise in this manner.
• Make sure that is the steams pressure which comes from steam installation has a higher value then technical detail which reported.

"Heat exchanger leaks water out "

• Control the tighteening measure of between two outer body of the heat exchanger is not more than described at front sticker. If there are differences , bring to a minimum distance between two bodies.

"The two fluid passing through heat exchanger is mixing"

• One or more plates may be drilled. Mixing problem is not about gaskets.
• Turn off all input and output valves of heat exchanger. Contact with service department.
