ZETA 2002 - water chiller

Air-cooled liquid chillers with hermetic scroll compressors and plate type evaporator, suitable for outdoor installations. The unit has a refrigerant circuit for each pair of compressors.

UNIT FRAME

Self supporting frame with removable panels, internally coated with expanded polyurethane sound-absorbing material; constructed from galvanized sheet steel with RAL 5014 powder paint baked at 180°C to provide a durable weatherproof finish. Threaded fasteners in stainless steel.

COMPRESSORS

Hermetic scroll type with orbital motion, connected in tandem and equipped with oil level sight glass, Klixon internal thermal protection and oil equalisation line. The compressors are housed in a sound insulated compartment and separated from the air flow; access is provided by removable panels which allow maintenance work to be performed in safety even when the unit is in operation.

CONDENSER

Composed of a high efficiency coil manufactured from copper tubes and aluminium fins. The finned coil is protected by a metal grille which is installed as standard.

CONDENSER FANS

Axial fans directly coupled to 6 pole motors with internal Klixon overload protection. Motor protection category is IP 54. The fan is equipped with a safety grille to UNI EN 294.

EVAPORATOR

Brazed plate type in 316 AISI stainless steel. Thermal insulation of evaporator is provided by closed cell expanded material. Each evaporator is equipped with a low water temperature probe for freeze protection and each unit is equipped as standard with a mechanical flow switch.

REFRIGERANT CIRCUIT

Comprising: liquid valve, charge connection, liquid sight-glass, filter/dryer, thermostatic expansion valve with external pressure equalisation, high and low pressure switches for 2-compressor models. For 4-compressor models high and low pressure values and relative condensation and evaporation temperatures are measured by pressure transducers that relay the signals to the controller so that they can be read directly on the display. The high pressure side of the circuit is equipped with high pressure switches and relief valves.

ELECTRICAL PANEL

The electrical panel includes:

- main switch

- thermal magnetic circuit-breakers for fans and (if present) pumps; compressor fuses for the power circuit

- compressor contactors

- fan contactors

- pump contactors (ST version)

The microprocessor controls the following functions on all units:

- water temperature regulation

- freeze protection

- compressor time intervals

- compressor start sequence and automatic lead/lag selection

- alarm reset

- common alarm contact for remote signalling

- operating and alarm indicator LEDs

REFRIGERANT CIRCUIT ACCESSORIES:

- Step type condensing pressure control

(ambient air minimum temperature 0 °C).

The control is managed in On/Off mode by the microprocessor by means of the pressure transducers. Available for models 18.4 to 26.4 only.

modified manually on the controller. For four compressor units two set-points can be programmed and switched between them from the keypad or using a digital input. The type of selection must be specified at the time of the order. In all cases the thermostatic valves switch automatically on the basis of the water temperature.

Attention: before repairing or servicing the unit, ensure that the electrical supply is disconnected.

Any work on the unit must be carried out by trained people only.

1. FIELD OF APPLICATION

The equipment is designed for cooling (chiller only versions) or cooling/heating (heat pump version) water, which is usually utilised for air conditioning or refrigeration applications. The units must be used exclusively within the operating limits specified in Section 4.

1.1 INTRODUCTION

- When installing or servicing the unit, it is necessary to strictly follow the rules described in this manual, to conform to all the items detailed on the unit labels and take any necessary precaution.

- Pressure in refrigerant circuits and danger from electrical shock can be hazardous when installing or servicing the unit.

2. INSPECTION, TRANSPORT, SITE HANDLING

2.1 INSPECTION

After receiving the unit, immediately check its integrity. The unit will have left the factory in perfect condition. Therefore on receiving the unit any damage must be verbally described to the carrier and recorded on the Delivery Note before it is signed by both parties. Blue Box or their Agent must be informed as soon as possible of the extent of the damage. The Customer should prepare a written statement and photographic evidence regarding any severe damage.

2.2 LIFTING AND SITE HANDLING

Avoid sudden movements and jolts when unloading and positioning the unit. Internal handling procedures must be conducted with care. Do not exert leverage on the components of the machine. The unit must be lifted by inserting steel tubes through the lifting attachments shown by the relative signs (yellow arrow). The unit must be lifted by harnessing it as shown in figure 1: use ropes or straps of sufficient length and spacer bars to avoid damage to the unit’s side panels and cover. Alternatively, the unit (with a maximum length less than

3.5 m) can be lifted by a forklift truck, inserting the forks under the pallet.

Caution: ensure that the method of lifting does not allow the unit to slip from chains and slings and does not allow the unit to turn over or slide from lifting devices.

2.3 UNPACKING

When unpacking the unit pay attention not to damage the unit. Packaging consists of different materials: wood, paper, nylon etc. Separate the materials and deliver to the proper gathering centre in order to reduce their environmental impact.

3. SAFETY PRECAUTIONS

3.1 DEFINITION OF DANGER ZONE

Only authorised operators must be allowed in the vicinity of the unit.

- The external danger zone concerns a space of approximately 2 m in width around the perimeter of the machine. Access to this area must be prevented by suitable guarding in the event that the unit is located in an unprotected area that is easily accessible to unauthorised persons.

- The internal danger zone is defined as the interior of the machine. Access to the interior of the machine must not be permitted to unqualified personnel and never before the machines' electrical supply has been disconnected.

3.2 SAFETY PRESCRIPTIONS

The unit is designed and built in accordance with the PED 97/23CE rules, to ensure the maximum level of safety. To avoid possible situations of risk adhere to the following rules at all times:

- All work on the unit must be performed by qualified personnel. Before working on the unit, ensure that the designated personnel are conversant with the documentation supplied. Always ensure there is a copy of the documentation in the immediate vicinity of the unit.

- Use the appropriate personal safety equipment (gloves, helmet, safety goggles, safety footwear, etc.) for all maintenance and control operations on the unit.

- Use only tools and equipment that are in good working order.

- The fans have protective grilles to prevent accidental contact. Use the maximum caution to avoid inserting or dropping objects through the grilles.

- The exchanger coils have sharp edges. Do not touch the coils without using suitable protection.

- The compressor compartment contains various high temperature components. Adopt the maximum caution when working in the vicinity of the compressors and avoid touching any parts of the unit without appropriate protection.

- Do not work within the theoretical discharge trajectory of the relief valves.
