2ABOUT SAFETY

Transportation

⚠WARNING

•Transportation must be carried out in compliance with local laws and regulations.

Lifting

⚠WARNING

•Lifting must be performed in accordance with the installation instructions in this

Manual. Manufacturer is not responsible for any equipment damage, personal

injury or death resulting from failing to comply with these requirements.

•The equipment must be lifted with the utmost attention and care. Avoid jolting

when lifting and lift the machine very slowly, keeping it perfectly level.

•It is prohibited to stay under the crane or equipment during lifting.

⚠CAUTION

•Lifting should be performed by experienced personnel who is familiar with the

provisions of law and local regulations, and who has been properly trained or has

experience with this type of equipment.

IMPORTANT

•It is advisable to add some insulation material between lifting ropes and machine

to avoid scratching the equipment.

⚠CAUTION

•The stability of the equipment during shipping must be ensured.

•Block equipment from sliding on lorries to prevent damage to the panels and base

frame. Avoid bumping, jolting and impacts during unloading and/or moving the

machine. Do not push or pull the equipment from any part other than the base frame.

Failure to follow above-mentioned instructions could cause serious damages for

which the manufacturer will not be held liable.

Installation

Unit installation

⚠WARNING

Installation should be performed by experienced personnel. Avoid installing the equipment in a place

that could be dangerous during maintenance operations, such as (but not limited to) platforms without

parapets or railings, or areas not complying with the clearance requirements.

⚠CAUTION

•Installation must be performed in accordance with the installation instructions in

this Manual.

•If the unit operates cooling mode when ambient temperature is lower than 5°C

and wind speed is more than 10 m/s, please consult manufacturer.

IMPORTANT

•Install a strainer on the inlet to each heat exchanger. Failure to install a strainer

allows solid particles and/or welding slags to enter the heat exchanger. Installation

of a strainer with mesh size recommended by manufacturer (refer to page 16). The

manufacturer will not hold responsible for any damage to heat exchanger due to

blockage.

•All other water piping outside the chiller must be protected against freezing.

•Adjust the anti-vibration mountings beneath the equipment before connecting

water pipe.

Electrical installation

⚠CAUTION

•All electrical connections to the machine must be carried out in compliance with

laws and regulations in force.

•All installation, operating and maintenance activities must be carried out by

qualified personnel.

•Please refer to the specific wiring diagram for the machine that you have

purchased, and which was sent with the unit.

•Should the wiring diagram not come with the machine, please contact your dealer

for further action.

•Use copper conductors only. Failure to use copper conductors could cause

overheating or corrosion at the connection points and damages the unit.

•To avoid interference, all control wires must be installed separately from the

power wires. Use separate electrical conduits for this purpose.

•Before servicing the machine in any way, open the general disconnecting switch

on the machine's main power supply.

•When the machine is off, but the disconnector switch is in the closed position,

unused circuits are live as well.

•Never open the terminal board box of the compressors before having opened the

unit's general disconnecting switch.

•In installations with power supply lines longer than 50 meters, inductive coupling

between phases and between phase and earth generates significant

electromagnetic field.

•In order to limit these phenomena, it is good practice to lay out the phase wires

symmetrically, as described in the figure:

•Chiller unit compressors are single-direction rotation compressors and can be damaged if

rotated in the wrong direction. For this reason, proper phasing of electrical power is

important. Terminal block indicator (R, S, T). R=L1, S=L2, T=L3
