instructions

Always observe the following safety instructions and regulations.

Unit installation (see "5Unit installation"[44])

WARNING

CVXM-A and FVXM-A Floor Standing range is allowed to be combined only with systems with total refrigerant amount <1.842 kg. Therefore in case of combination with outdoor units 3MXM40N8 or 3MXM52N8, the total liquid refrigerant piping length of the installation MUST be ≤30m.

WARNING

The appliance shall be stored in a room without continuously operating ignition sources (example: open flames, an operating gas appliance or an operating electric heater).

CAUTION

For walls containing a metal frame or a metal board, use a wall embedded pipe and wall cover in the feed-through hole to prevent possible heat, electrical shock, or fire.

Piping installation (see "6Piping installation"[49])

DANGER: RISK OF BURNING/SCALDING

CAUTION

▪ Use the flare nut fixed to the unit.

▪ To prevent gas leakage, apply refrigeration oil only to

the inside of the flare. Use refrigeration oil for R32.

▪ Do NOT reuse joints.

CAUTION

▪ Do NOT use mineral oil on flared part.

▪ NEVER install a drier to this R32 unit to guarantee its

lifetime. The drying material may dissolve and damage the system.

CAUTION

▪ Incomplete flaring may cause refrigerant gas leakage.

▪ Do NOT re-use flares. Use new flares to prevent

refrigerant gas leakage.

▪ Use flare nuts that are included with the unit. Using

different flare nuts may cause refrigerant gas leakage.

WARNING

ALWAYS use multicore cable for power supply cables.

WARNING

Use an all-pole disconnection type breaker with at least 3 mm between the contact point gaps that provide full disconnection under overvoltage category III.

WARNING

If the supply cord is damaged, it MUST be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

WARNING

Do NOT connect the power supply to the indoor unit. This could result in electrical shock or fire.

WARNING

▪ Do NOT use locally purchased electrical parts inside

the product.

▪ Do NOT branch the power supply for the drain pump,

etc. from the terminal block. This could result in electrical shock or fire.

WARNING

Keep the interconnection wiring away from copper pipes without thermal insulation as such pipes will be very hot.

3.1 Indoor unit

Electrical installation (see "7Electrical installation"[410])

DANGER: RISK OF ELECTROCUTION

WARNING

▪ All wiring MUST be performed by an authorised

electrician and MUST comply with the applicable legislation.

▪ Make electrical connections to the fixed wiring.

▪ All components procured on-site and all electrical

construction MUST comply with the applicable legislation.

WARNING

▪ If the power supply has a missing or wrong N-phase,

equipment might break down.

▪ Establish proper earthing. Do NOT earth the unit to a

utility pipe, surge absorber, or telephone earth. Incomplete earthing may cause electrical shock.

▪ Install the required fuses or circuit breakers.

▪ Secure the electrical wiring with cable ties so that the

cables do NOT come in contact with sharp edges or piping, particularly on the high-pressure side.

▪ Do NOT use taped wires, stranded conductor wires,

extension cords, or connections from a star system. They can cause overheating, electrical shock or fire.

▪ Do NOT install a phase advancing capacitor, because

this unit is equipped with an inverter. A phase advancing capacitor will reduce performance and may cause accidents.

3.1.1 To remove the accessories from the indoor unit

1 Remove the accessories located at the bottom of the package.

Spare SSID sticker is located on the unit.
