❸ Maintenance; I Winterizing; I Maintenance - Zodiac Heat Select ZS500 Series Instructions For Installation And Use Manual

3.1 I Winterizing

• Winterizing is vital to prevent the condenser from being damaged due to freezing. This is not
covered by the warranty.
• To avoid damaging the equipment with condensation, do not fully cover it; a winterizing cover
is provided.
• Set the regulator to "standby" mode by pressing and holding
• Open valve B,
• Close valves A and C and open valves D and E (if present),
• Make sure that there is no water circulating in the heat pump,
• Drain the water from the condenser (risk of freezing) by unscrewing the two water input and output connectors on
the back of the heat pump,
• In the case of full winterizing for the pool (complete shutdown of the filtration system, bleed the filtration circuit
or even pool drainage): tighten the two connectors by one turn to prevent any foreign bodies from getting into the
condenser,
• In the case of winterizing for the heat pump only (shutdown of the heating only, the filtration keeps running): to not
tighten the connectors but add 2 caps (provided) on the condenser's water inputs and outputs.
• We recommend that you put the aired winterizing micro cover (provided) on the heat pump.

3.2 I Maintenance

• Before performing any maintenance operation on the appliance, you must disconnect the
electrical power supply to the appliance as there is a risk of electric shock which may cause
material damage, serious injury or even death.
• Do not disconnect the electricity supply when the device is running.
• If the electric power supply is interrupted, wait a minute before restoring the power.
• It is recommended that the device be general serviced at least on a yearly basis to ensure
proper operation, maintain performance levels and prevent some potential failures. These
operations are carried out at the user's expense, by a technician.
3.2.1 User maintenance
• Make sure that the filter is not blocked by any foreign bodies.
• Clean the evaporator (for location see § "5.3 I Dimensions and marking") using a soft brush and a fresh water spray
(disconnect the power cable); do not fold over the metal wings, then clean the condensation drainage pipe to remove
any impurities that may be blocking it.
• Make sure that the electrical unit's ventilation grid is clean.
• Do not use a high pressure jet. Do not spray with rain water, salt water or water which is full of minerals.
• Clean the outside of the device; do not use any solvent-based products. We can provide you with a specific cleaning
kit as an accessory: the PAC NET, see § "5.1 I Description".
3.2.2 Maintenance to be carried out by a qualified technician
• Check that the regulation is operating correctly connected.
• Check that the condensation flows correctly when the device is operating.
• Check the safety mechanisms.
• Check the connection of the metal masses to the earth.
• Check that the electrical cables are correctly tightened and connected and that the electrical unit is clean.
