Regular Maintenance; Operating Problems; Error Codes - Jula 416-067 Operating Instructions Manual

Regular maintenance


Check the water flow regularly. Too little water or leakage will disrupt the operation of the heat
pump and can cause damage to the unit.

Check the pool filter regularly.

The area around the heat pump must be in order, clean and dry. Clean the pool heat pump
regularly, but NEVER rinse water directly over the pool heat pump.

Check the connections on the pool heat pump regularly.

Drain the water from the pool heat pump if you do not intend to use it for a long period of time or if
there is a risk of frost.

The unit must be stored vertically.

Regularly check that the wheels and feet are secured properly. Retighten, if necessary.

Operating problems

Note that when the temperature changes this significantly affects the capacity and efficiency of the heat
pump. Consequently, a perceived fault may be a misjudgement of the heat pump's capacity and should
therefore not be seen as an operating problem. The pool heat pump must not be used when it is colder
than about 5 °C. Drain the water from the pump during the winter and store in an area free from frost.
Remove the hoses, drain the water from the unit. The pool heat pump is designed to improve the comfort
during the bathing season and to extend it during the spring and autumn. The outdoor temperature and
insulation are decisive for the temperature reached in the pool.
The stated output for the pool heat pump applies at 27 °C and 21.5 °C. At lower outdoor temperatures the
output will be lower. The stated recommendations are based on industry standards and are an estimate
based on normal insulation and operating temperatures.

Error codes

Error codes are shown on the display to indicate a possible error. The unit stops and an error code is
shown. See the examples of error codes in the table below.
