If the installation requires a useful head higher than that obtained by installing a pump assembly and storage tank, it is recommended that an additional pump is installed on the unit. Provided the additional pump installed inside of unit, the pump must connected close to plate heat exchanger. Provided the pump installed outside of unit, the pump shall be connected at water pipe’s outlet. The pump can be easily installed on the unit by removing the pump connection pipe. Connect to terminal PL,PN on the electric panel.
Important
1) The chillers must be provided with a filling/top-up system connected to the return line and a drain cock in the lowest part of the installation. Installations containing anti-freeze or covered by specific legislation must be fitted with hydraulic disconnections.
2) The manufacturer is not liable for obstruction, breakage or noise resulting from the failure to install filters or vibration dampers. Particular types of water used for filling or topping up must be treated with appropriate treatment systems. For reference values, see the table.

g). Design of expansion tank
If a closed expansion tank with its filled volume of air is too small, the system pressure will easily exceed the
maximum allowable pressure and cause water to discharge from the pressure relief valve, thus wasting
water. If the closed tank is too large, when the water temperature drops, the system pressure may decrease
to a level below the minimum allowable value and cause trouble in the air vent. Therefore, accurate sizing of
a closed expansion tank is essential.
For diaphragm expansion tanks, the minimum volume of the water tank, Vt, gal(m3),can be calculated by the
following formula, recommended by ASHRAE Handbook 1996, HVAC Systems and Equipment:
V
t=Vs
v2/v1-1-3α(T2-T1)
1-p
1/p2
T1=lower temperature,oF (℃)
T2=higher temperature, oF (℃)
Vs=volume of water in system, gal(m3)
p1=absolute pressure at lower temperature,psia(kPa abs.)
p2=absolute pressure at higher temperature,paia(kPa abs.)
v1,v2=specific volume of water at lower and higher temperature, respectively, ft3/lb(m3/kg)
α=linear coefficient of thermal expansion; for steel, α=6.5x10
-6
in./in·oF(1.2x10-5per ); for copper,
α=9.5x10
-6
in./in·oF(1.7x10-5per )
In a chilled water system, the higher temperature T2 is the highest anticipated ambient temperature when

the chilled water system shuts down during summer. The lower temperature in a heating system is often the
ambient temperature at fill conditions(for example, 50 oF or 10℃).
h). Water quality control
When industrial water is used as chilled water, little furring may occur; however, well water or river water, used as chilled water, may cause much sediment, such as furring, sand, and so on. Therefore, well water or river water must be filtered and softened in softening water equipment before flowing into chilled water system. If sand and clay settle in the evaporator, circulation of chilled water may be blocked, and thus leading to freezing accidents; if hardness of chilled water is too high, furring may occur easily, and the devices may be corroded. Therefore, the quality of chilled water should be analyzed before being used, such as PH value, conductivity, concentration of chloride ion, concentration of sulfide ion, and so on.
PH 6-8
Total hardness less than 50 ppm
Electrical conductivity
less than 200 mV/cm (25°C)
Sulfide ion none
Chlorine ions less than 50 ppm
Ammonia ions none
Sulfate ion less than 50 ppm
Silicon less than 30 ppm
Total iron less than 0.3 ppm
Sodium ion No requirement
Calcium ion less than 50 ppm
Filling the installation
- Before filling, check that the installation drain cock is closed.
- Open all installation and terminal air vents.
- Open the gate valves.
- Begin filling, slowly opening the water filling cock outside the unit.
- When water begins to leak out of the terminal air vent valves, close them and continue filling until the pressure gauge indicates a pressure of 1.5 bars.
Emptying the installation
- Before emptying, place the mains switch in the“off” position.
- Make sure the installation fill/top-up water cock is closed.
- Open the drain cock outside the unit and all the installation and terminal air vent valves.

i). Electrical connection
The unitary mini chillers leave the factory already wired, and require the installation of an omni polar thermal overload switch, a lockable mains disconnecting switch for the connection to the mains power supply, and the connection of the flow switch to the corresponding terminals. All the above operations must be carried out by qualified personnel in compliance with the legislation in force.
For all electrical work, refer to the electrical wiring diagrams in this manual. You are also recommended to check that the characteristics of the mains electricity supply are adequate for the absorptions indicated in the electrical characteristics table below, also bearing in mind the possible use of other equipment at the same time.
Important
Power to the unit must be turned on only after installation work (hydraulic and electrical) has been
completed.
All electrical connections must be carried out by qualified personnel in accordance with legislation in
force in the country concerned.
Respect instructions for connecting phase, neutral and earth conductors. The power line should be fitted upstream with a suitable device to protect against short-circuits and
leakage to earth, isolating the installation from other equipment.
Voltage must be within a tolerance of ±10% of the rated power supply voltage for the unit (for three
phase units, the unbalance between the phases must not exceed 3%).If these parameters are not respected, contact the electricity supply company.
For electrical connections, use double insulation cable in conformity with current legislation in the
country concerned.
An omnipolar thermal overload switch and a lockable mains disconnecting switch, in compliance with
the CEI-EN standards (contact opening of at least 3mm), with adequate switching and residual current protection capacity based on the electrical data table shown below, must be installed as near as possible to the appliance.
The devices on the unit must be lockable. An efficient earth connection is obligatory. Failure to earth
the appliance absolves the manufacturer of all liability for damage.
Do not use water pipes to earth the unit.
Electrical Panel
The electrical panel is located inside the unit at the top of the technical compartment where the various components of the refrigerant circuit are also to be found.
To access the electrical panel, remove the front panel of the unit by undoing the screws.

sure that:
- All safety conditions have been respected.
- The chiller is adequately fixed to the surface it rests on.
- Functional distances have been respected.
- Hydraulic connections have been carried out as indicated in the manual.
- The water circuit is filled and vented. When draining after heat pump operation, take care as the water may be hot.
- The water circuit valves are open.
- Electrical connections have been carried out correctly.
- Voltage is within a tolerance of 10% of the rated voltage for the unit.
- The unit is correctly earthed.
- All electrical and hydraulic connections are tight and have been completed correctly.
- Use grommet A for the electrical power cable and grommet B for the other external wires.

15. Running and Maintenance
a) Operating characteristics
Set point in cooling mode
(factory set) = 12°C, Hysteresis = 3°C. The compressor starts with water temperatures above 12°C. The compressor shuts down with water temperatures of less than 9°C.
Set point in heating mode
(factory set) = 40°C, Hysteresis = 4°C. The compressor starts with water temperatures below 38°C. The compressor shuts down with water temperatures above 42°C. In the event of a temporary power failure, when power returns, the mode set previously will be retained in the
memory.
Compressor start up delay
Two functions prevent the compressor from starting up too frequently
- Minimum time since last start-up 300 seconds.
Pump
The electronic board includes a pump control output. The pump starts when the assembly is powered up and at least 285 seconds before the compressor starts up and stops 120 seconds after the assembly shuts down. After the first 120 seconds of pump operation when the water flow is at full speed, the water flow alarm functions are activated (differential pressure switch and flow switch). With a pump connected to terminals PL and PN on the installer terminal board.
Fan speed control
For correct operation of the unit with different outside temperatures, the microprocessor controls the fan speed based on the pressure reading from the pressure probe, thus enabling heat exchange to be increased and/or decreased, maintaining the condensing or evaporation temperature practically constant.
The fan functions independently of the compressor.
Frost prevention alarm
To prevent the water freezing and damaging the plate heat exchanger, the microprocessor shuts down the compressor if the temperature measured by the heat exchanger outlet temperature sensor is less than 3°C. The frost prevention temperature set point can be modified by an authorized service center only and only after verifying that the water circuit contains antifreeze. Tripping of this alarm shuts down the compressor but not the pump, which remains active. To reset normal functions, the outlet water temperature must rise to more than +15°C. Reset is manual.
Water flow alarm
The microprocessor provides for management of a water flow alarm controlled by a differential pressure switch fitted as standard on the appliance to be installed on the water delivery piping.
This safety device may trip after the first 120 seconds of pump operation when the water flow is up to speed. Tripping of this alarm shuts down the compressor but not the pump, which remains active. To reset normal
functions, the alarm contact must be deactivated for at least 15 seconds. When electrical current exceeds to setting value and condenser temperature over than 62°C, system will
shut down, but not returns to normal operation until the condenser temperature decreased less than 52°C.
45
Page 48
b) Routine maintenance
Never perform any cleaning operations before having disconnected the unit from the mains power supply. If the supply cord is damaged, it must be replaced by the manufacturer or its service agent or a similarly
qualified manufacturer or its service agent or a similarly qualified. Regular maintenance is fundamental to maintain the efficiency of the unit both in terms of operation and
energy consumption. The Technical Assistance Service maintenance plan must be observed, with an annual service which includes the following operations and checks:
- Filling of the water circuit.
- Presence of air bubbles in the water circuit.
- Efficiency of safety devices.
- Power supply voltage.
- Power input.
- Tightness of electrical and hydraulic connections.
- Condition of the compressor contactor.
- Efficiency of the plate heat exchanger heater.
- Checking of operating pressure, superheating and sub cooling.
- Efficiency of compressor heater.
- Cleaning of finned coil (*).
- Cleaning of fan grills.
- Cleaning of condensate drain pan (if installed).
(*) For “Heat pump” appliances, the checks are to be performed quarterly.
For units installed near the sea, the intervals between maintenance should be halved.
c) Extraordinary maintenance
Never perform any cleaning operations before having disconnected the unit from the mains power supply.
Chemical washing
You are recommended to chemically wash the plate heat exchanger after every 3 years of operation.
Refrigerant gas content
The chillers are filled with R410a refrigerant gas and tested in the factory. In normal conditions, there should be no need for the Technical Assistance Service to intervene to check the refrigerant gas. However, over time, small leaks may develop at the joints leading to loss of refrigerant and draining of the circuit, causing the unit to function poorly. In this case, the leaks of refrigerant must be identified and repaired and the refrigerant circuit refilled. Proceed as follows:
- Empty and dry the entire refrigerant circuit using a vacuum pump connected to the low and high pressure tap until the vacuum meter reads about 10Pa. Wait a couple of minutes and check that this value does not rise to more than 200Pa.
- Connect the refrigerant gas cylinder or a filling cylinder to the low pressure line pressure gauge connection.
- Fill with the quantity of refrigerant gas indicated on the rating plate of the unit.
- Always check the superheating and sub cooling values. In the nominal operating conditions for the appliance, these should be between 5 and 10°C and between 4 and 8°C respectively.
- After a couple of hours of operation, check that the liquid indicator indicates circuit dry (dry-green).
Important
In the event of partial leaks, the circuit must be completely emptied before being refilled The R410a refrigerant must only be filled in the liquid state. Operating conditions other than nominal
conditions may produce considerably different values. Seal testing or identification of leaks must only be carried out using R410a refrigerant gas, checking with a
suitable leak detector.
46
Page 49
Prohibition
1. The refrigerant circuit must not be filled with a refrigerant other than that indicated of specification.
2. The use of a different refrigerant may cause serious damage to the compressor.
3. Oxygen, acetylene or other inflammable or poisonous gases must never be used in the refrigerant circuit as they may cause explosion or poisoning.
4. Oils other than those indicated on manual before must not be used. The use of different oils may cause serious damage to the compressor.
d) Shutting down for long periods
If it is previewed not to use the machine for long periods After deactivating the chiller:
-Make sure the model is in the power off model " ", or alternatively disconnect the unit from the power supply.
-Make sure the remote control switch is closed (if present) .
-Close the water valves.
Important
If there is a possibility that the outside temperature may drop below zero, there is the risk of freezing. The water circuit MUST BE EMPTIED AND SHUT OFF POWER (when draining after heat pump operation
take care as the water may be hot) or antifreeze must be added in the proportion recommended by the manufacturer.
