1. DESCRIPTION OF UNIT AND TECHNICAL SPECIFICATIONS
The refrigerant chillers in this series are designed for residenal and commercial applicaons. The use of brushless inverter compressor technol-
ogy, combined with an electronic expansion valve, circulator and variable speed fan, opmise the consumpon and operang eciency of the
cooling components.
FRAMEWORK
Structure suitable for outdoor installaon consisng of thick proles in hot galvanised sheet metal painted with polyester powder, colour RAL
7035 textured, resistant to atmospheric agents.
The removable panels allow maintenance inside the refrigeraon and hydraulic circuits.
COMPRESSORS
Twin rotary hermec inverter controlled DC compressors, specically designed to operate with R32, equipped with thermal
protecon and mounted on rubber vibraon dampers.
This component is installed in a compartment separate from the air ow to reduce noise and is equipped with a crankcase heater that prevents
the diluon of the oil by the refrigerant, ensuring correct lubricaon and reducing wear on moving parts.
The compressors can be inspected by removing the side and front panels of the unit, allowing maintenance even when the unit is running.
AIR SIDE HEAT EXCHANGER
The air exchangers are made enrely of aluminium using micro-channel technology, which makes it possible to signicantly reduce both the
pressure drops on the air side and the refrigerant charge, at the same me guaranteeing a greater exchange capacity with the same frontal sur-
face area compared to tradional exchangers and a lower refrigerant charge. On request, the coils can have surface treatments to allow greater
resistance to corrosion.
UTILITY SIDE HEAT EXCHANGER
Gli scambiatori possono essere equipaggia di resistenza elerica angelo (accessorio opzionale KA1). Brazed plate heat exchanger made of AISI 304
stainless steel, coated with black exible closed-cell elastomeric foam; thickness 9 mm, thermal conducvity (λ)≤0.036 W/mK (at air +20°C). A ow
switch installed on the water side ensures the presence of water ow and, together with the protecon probe, prevents the formaon of ice inside.
The exchangers can be equipped with an electric anfreeze heater (oponal accessory KA1).
FAN
The fans are axial type with airfoil blades. They are stacally and dynamically balanced and supplied complete with protecon grille and air inlet
and outlet with double ared prole, specially shaped to increase eciency and reduce noise. The electric motor used is driven in modulaon
with brushless EC motor, directly coupled, and equipped with integrated thermal protecon. The motor has an IP 54 protecon rang according
to CEI EN 60529.
COOLING CIRCUIT
The cooling circuit is made of copper piping, brazed and assembled in the factory in accordance with EN 13134. The components present are:
• Filter drier with 100% molecular sieve cartridge;
• Shut-o valve on the liquid line;
• Liquid ow and moisture indicator;
• Electronic expansion valve;
• Charge connecons;
• High-pressure safety pressure switches;
• High and low pressure transducers.
The sucon line is thermally insulated with exible, closed-cell elastomeric foam.
Each unit is pressure tested to check for leaks and is supplied complete with a refrigerant charge opmised for operaon.

2. DESCRIPTION OF VERSIONS AND ACCESSORIES
VERSIONS
The available versions are:
i-32V5C Midi - standard version chiller
i-32V5C-DS Midi - chiller with desuperheater
The unit with desuperheater includes the addion of a brazed plate type heat exchanger made of AISI 316 stainless steel, factory insulated using
closed cell material. This version allows to recover about 20% of the condensing heat otherwise lost and to use it to feed the aer-heang water
coils of an AHU or for a hot water ywheel or for any other process use.
i-32V5C-BT Midi - BT version chiller (for low water temperatures)
The BT version unit allows the operang range of the unit to be extended by cooling water to -8°C. In this case, a mixture of water and glycol is
used.

Fan silent mode
Digital input that can be acvated by an external contact that allows the reducon of the sound power level by acng on the venlaon. The
mode is parcularly suitable during night operaon. The decreases in capacity and sound power level when the "fan silent mode" funcon is
acve are shown below.
The reducon refers to the test condion (1) of the technical data tables; the value is determined on the basis of measurements carried out in
accordance with UNI EN ISO 9614-2, in compliance with the requirements of Eurovent cercaon.

The treatment consists in the applicaon by spraying of a special water-based paint made of new resins with very high chemical resistance. The
product is exible to resist thermal contracon and expansion, UV resistant, dirt repellent, mechanically resistant, with very low heat transmis-
sion losses and praccally no eect on air-side pressure drops.
The treatment withstands 6000 h according to ASTM B117.

Heat exchanger adhesive resistor - electrical resistor located on the front face of the plate heat exchanger, which is acvated when the tempera-
ture of the water inside the exchanger drops below +4°C. For BT units, this value must be set according to the percentage of glycol in the system
and the freezing point of the mixture.

7-touch/HUB (Cloud/App)
7-touch/HUB (Cloud/App) is a compact system consisng of an ultra-thin touch panel, including a temperature control unit and gateway for
remote control from a PC (via the "my.maxa.it" portal) or smartphone (via the app downloadable from the "My Maxa" online store). It allows
winter and summer climate control.
Remote touch screen display (Hi-TV415)
remote touch screen control for the centralised management of a chiller/heat pump network, it integrates humidity and
temperature sensors for the thermo-hygrometric analysis of the environment and the management of the double set point
for radiant oor systems that use a dehumidicaon system.
Remote control (I-Cr)
Modbus remote control with negave LCD and capacive keys. The device is to be used as a remote machine keyboard with
local temperature detecon, replicang the funcons of the on-board control.
3. INSTALLATION
All handling, installaon and maintenance operaons must be carried out by QUALIFIED PERSONNEL only. Before any operaon on the unit,
make sure that the power supply is disconnected.
The minimum permissible temperature for storing the units is 5°C.

All models in the series are designed and constructed for outdoor installaon.
It is good pracce to create a support slab of adequate size for the unit. The units transmit a low level of vibraon to the ground: it is never-
theless advisable to place an-vibraon mounts between the base frame and the support surface.

It is very important to avoid recirculaon phenomena between sucon and delivery, otherwise the performance of the unit will deteriorate or
even interrupt normal operaon.
In this respect it is absolutely necessary to guarantee the minimum service spaces indicated below.

It is always advisable to make an environmental impact assessment based on the power and sound pressure data given in the technical data
chapter and the sound emission limits based on the installaon area of the unit, with reference to the DPCM of 14/11/1997. An assessment must
also be made if the unit is installed in the vicinity of workers, according to D. LGS. 81/2008 Art. 189 and following.
4. HYDRAULIC CIRCUIT
The hydraulic connecons must be made in accordance with naonal or local regulaons; the piping can be made of steel, galvanised steel or
PVC. The pipes must be carefully sized according to the nominal water ow rate of the unit and the pressure drops of the hydraulic circuit. All
hydraulic connecons must be insulated using closed-cell material of adequate thickness. The chiller must be connected to the piping using new,
non-reused exible couplings. It is recommended to install the following components in the hydraulic circuit:
• Thermometers to measure the temperature in the circuit.
• Manual gate valves to isolate the chiller from the hydraulic circuit.
• Y-shaped metal lter and a dirt separator (installed on the return pipe from the system) with a metal mesh of no more than 1 mm (obligatory
to maintain the validity of the guarantee).
• Loading unit and discharge valve where necessary.

Minimum water content and hydraulic circuit volumes.
The table shows the minimum system water content recommended per unit. The volume of the hydraulic circuit is also indicated. If this volume
is less than the recommended minimum water content, it must be ensured that the pipes connecng to the unit have sucient capacity to com-
pensate for this dierence. The addional volume required is shown in the table.
