7. Routine, scheduled and extraordinary maintenance.
Periodic controls are required to keep SERIES BP heat pumps in good working order and to
guarantee the foreseen performance and safety levels. Some controls can be performed by the
user while specialised technicians are required for others.
During normal operations, the heat pump plate heat exchanger produces condensation.
The amount of condensation produced varies according to ambient conditions. The
higher the air humidity, the higher the amount of condensation produced. The lower
heat pump panel acts as a condensation collection tray. Keep the drain hole clean.
7.1. User controls.
SERIES BP heat pump users must periodically make sure that:
• Dirt is not accumulated near the heat pump (leaves, paper, etc.). Performing this
control weekly is recommended. Use caution when nearing the plate heat
exchanger blade since rather sharp.
• There are no leaks in the hydraulic circuit. Conduct this control monthly.
• Electrical mains wires and connections are integral, Performing this control monthly
is recommended.
• The correct chemical balance in the pool water is guaranteed in order to guarantee
hygienic accessibility conditions and long heat pump life. Conducting this control
daily with specific retail kits is recommended.
• The pressure values indicated on the manometer are correct. See Paragraph 5.3.
• Make sure the condensation drain hole is open.
7.2. Specialised technician controls.
The following controls must be conducted by a specialised technician at least once a year
to guarantee safe and efficient SERIES BP heat pump operations:
• Electrical mains wire and connection integrity.
• Hydraulic system integrity.
• Inspect and clean the plate heat exchanger coil.
• Check correct heat pump operations, start, see Paragraph 5.2.4.
• Check usual pressure values indicated by the manometer, see Paragraph 5.3.
• Make sure there are no oil leaks from the compressor.
7.3. Winter protection.
The following instructions must be observed to protect SERIES BP heat pumps for the
winter:
• Disconnect the electrical mains using the protection device and/or contact switch,
see Paragraph 5.2.3.
• Drain the heat pump hydraulic system using the cut-off valve, see Paragraph 4.5.
• Protect the plate heat exchanger and fan from dirt accumulation. Do not wrap the
heat pump with plastic or other material that can hold heat and/or humidity inside
the device.
7.4. Spring commissioning.
The following instructions must be observed for SERIES BP heat pump spring
commissioning.
• Remove any protections used for winter protection, see Paragraph 7.3.
• Fill the heat pump hydraulic system using the cut-off valve, see Paragraph 4.5.
• Check the water chemical composition, see Paragraph 7.1, act accordingly if
necessary.
• Restore the electrical mains using the protection device and/or contact switch, see
Paragraph 4.6.
7.5. Troubleshooting.
The following table can be used to solve main heat pump problems. When a message
error is displayed, the following is required to restore operations:
