15. Troubleshooting guide

Incorrect installation may result in an electrical charge that could lead to death or serious injury
of users, installers or others by electrical shock and it may also cause damage to heat pump.

DO NOT

attempt to modify the internal configuration of the heat pump.

1. Keep your hands and hair clear of the fan blades to avoid injury.

2. If you are not familiar with your pool filtration system and heat pump:

a.

Do not

attempt to carry out any adjustment or service without consulting your

dealer, pool professional or air conditioning contractor.

b. Read the entire installation manual before attempting to use, service or make

adjustments to the unit.

c. Wait for 24hours after the installation before starting the heat pump to prevent

damage to the compressor. (If the heat pump has been transported and carried
all the time with the feet down, it can be started immediately).

Note:

Switch off the power before carrying out any maintenance or repairs.

IMPORTANT REMARK:

if a malfunction cannot be resolved immediately, in order to analyse

the problem we will need to know the message (error code) that is showing on the display
controller as well as the values for the settings (parameters 0-A). We also need to know the
status of the heat pump: the ambient temperature, water inlet / outlet temperature, if there is
cold air coming out from the heat pump, if the grill (evaporator) is cold, or if there is ice on the
heat pump.

Please keep this information at hand when calling customer service (describe the issue).

On the following pages you will find an overview of the different types of failure problems that
can occur together with instructions on how to solve them.
