Installation and operation manual

2 Specific installer safety instructions

2 Specific installer safety

instructions

Always observe the following safety instructions and regulations.

CAUTION

Do NOT insert fingers, rods or other objects into the air inlet or outlet. When the fan is rotating at high speed, it will cause injury.

General installation requirements

WARNING

Installation shall be done by an installer, the choice of materials and installation shall comply with the applicable legislation. In Europe, EN378 is the applicable standard.

WARNING

▪ Make sure to install all necessary countermeasures in

case of refrigerant leakage according to standard EN378 (see "11.1.2 Additional installation site

requirements for CO₂ refrigerant"[413]).

▪ Make sure to install a CO2 leak detector (field supply)

and enable the function for refrigerant leak detection (see "15.1Field setting"[421]).

WARNING

Installation site (see "11.1Preparing the installation

site"[412])

CAUTION

Appliance not accessible to the general public, install it in a secured area, protected from easy access.

This unit, both indoor and outdoor, is suitable for installation in a commercial and light industrial environment.

WARNING

Do NOT place objects below the indoor and/or outdoor unit that may get wet. Otherwise condensation on the main unit or refrigerant pipes, air filter dirt or drain blockage may cause dripping, and objects under the unit may get dirty or damaged.

WARNING

Install the unit only in locations where the doors of the occupied space are not tight fitting.

WARNING

When using safety shut-off valves, make sure to install measures such as a bypassing piping with a pressure relief valve (from liquid pipe to gas pipe). When the safety shutoff valves close and no measures are installed, increased pressure may damage the liquid piping.

Installing the ducting (see "11.2.2Guidelines when installing

the ducting"[415])

CAUTION

▪ Make sure the installation of the duct does NOT exceed

the setting range of the external static pressure for the unit. Refer to the technical datasheet of your model for the setting range.

▪ Make sure to install the canvas duct so vibrations are

NOT transmitted to the duct or ceiling. Use a soundabsorbing material (insulation material) for the lining of the duct and apply vibration insulation rubber to the hanging bolts.

▪ When welding, make sure NOT to spatter onto the

drain pan or the air filter.

▪ If the metal duct passes through a metal lath, wire lath

or metal plate of the wooden structure, separate the duct and wall electrically.

▪ Install the outlet grille in a position where the airflow will

not come into direct contact with people.

▪ Do NOT use booster fans in the duct. Use the function

to adjust the fan rate setting automatically (see

"15.1Field setting"[421]).

Refrigerant piping installation (see "12Piping

installation"[417])

CAUTION

Do NOT reuse piping from previous installations.

CAUTION

Install the refrigerant piping or components in a position where they are unlikely to be exposed to any substance which may corrode components containing refrigerant, unless the components are constructed of materials that are inherently resistant to corrosion or are suitably protected against corrosion.

WARNING

▪ Use K65 piping for high-pressure applications with a

working pressure of 120bar or 90bar, depending on its location in the system.

▪ Use K65 unions and fittings approved for a working

pressure of 120bar or 90bar, depending on its location in the system.

▪ Only brazing is allowed for connection of pipes. No

other types of connections are allowed.

▪ Expanding of pipes is not allowed.

Electrical installation (see "13Electrical installation"[418])

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 into 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.
