❹ Maintenance; I Winterising - Zodiac Z950 Instructions For Installation And Use Manual

4.1 I Winterising

• Winterising is recommended if the appliance is not used for a long period.
• In the case of winterising for the heat pump only, the appliance can be kept frost-free thanks
to the condenser and compressor resistors. In this case, it can continue to be powered and the
condensers will not require draining.
• If there is persistent frost, all filtering and heating system' components must be completely
emptied. Condensers are equipped with a side plug for this purpose.
• Turn off the regulator and disconnect the power supply,
• Open valve B,
• Close valves A and C (see § "2.2 I Hydraulic connections"),
• 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 inlet and outlet connectors on the
back of the heat pump (see D and E § "2.2 I Hydraulic connections"),
• In the case of full winterising 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 winterising for the heat pump only (shutdown of the heating only, the filtration keeps running): do not
tighten the connectors but add 2 caps (supplied) on the condenser's water inlets and outlets.
