Instructions
1 – Introduction
This instruction applies to fan-cooled condensing units for the refrigerant R290 (or similar inflammable gases).
During service only the refrigerant type stated on the condensing unit must be used.
2 – Versions
Version N0: for solder connection, has a nitrogen holding charge and is designed for use in refrigeration systems with capillary tube.
Version A09: for solder connection, has a helium/dry air holding charge and is designed for use in refrigeration systems with tubes for pressostats and premounted bracket. This version has premounted wired electrical box and one schrader port.
Version A10: for solder connection, has a nitrogen holding charge and is designed for use in refrigeration systems with premounted pressostats (HP and LP switch). This version has premounted wired electrical box, combo filter drier/receiver and one schrader port.
Version A11: for solder connection, has a nitrogen holding charge and is designed for use in refrigeration systems with capillary tube. This version has premounted wired electrical box and one schrader port.
3 – Refrigerant charging
With regard to evacuation and charging an condensing unit is to be treated as a compressor. Refrigerant charging must take place from a charging board not contaminated with refrigerants containing chlorine. No valves or flare connections of any kind must be used.
The condensing unit must be hermetically sealed, i.e. all connections must be soldered. After charging all solderings/connections are to be checked for leaks with a leak detector.
Keep away flammables from the condensing unit.
4 – Installation
•Install the condensing unit in the foreseen location.
•Prepare the tube connections from the evaporator.
• Use a drier with molecular sieves suitable for R290 (for versions N0, A09, A11).
• Use only dry and clean components and avoid moisture entering the system.
•The system components must not contain any chlorine, mineral oil or other oily substances.

Pressure switches (A10 version is premounted with HP/LP pressostats) and thermostats must also be mounted in an IP64 or higher classified box. Keep away flammables from the electrical equipment.
6 – Safety
•Disconnect the main power supply before service or repair.
•All connections at installation location must confirm with standard NFC15-100 in france or local and national standards/codes enforce in the country.
• Follow the information stated as per EN/IEC 6024/60335-2-89.
7 – Declaration of conformity
•All our condensing units are complied with low voltage directive 2014/35/EU and must be incorporated during installation.

•REGULATION (EU) 2015/1095, implementing Eco-design Directive 2009/125/EC with regard to Eco-design requirements for professional refrigerated storage cabinets, blast cabinets, condensing units and process Chiller.
•Condensing unit measurements are made
according to standard “EN 13771-2:2007”
– Compressor and condensing units for refrigeration-performance testing and test methodspart 2: Condensing units
•The following approvals must be obtained through authorised institutes like Nemko, Demko, BEAB, LCJE, etc. Among others EN 60 335-2-24, IEC 335-2-89, IEC 79-15.
8 – Maximum refrigerant charges R290 units with and without receiver
•The maximum charging amount must not exceed 150 g.
•It is recommended to charge only the amount necessary for the operation of the refrigeration system.
•The charging amount must be adapted to suit each system type.
•The condensing temperature must not exceed 55°C (N0 versions), 60°C (A09, A10, A11 versions) for stationary operation and 65°C for peak load.
9 – Cold start
The compressor must be allowed to assume a temperature higher than 10°C before it is started for the first time. This will prevent possible start problems caused by too high oil viscosity.
At lower temperatures some tripping of the winding protector may be expected until the viscosity of the oil becomes reduced.
10 – Winding protector
The compressors have a built-in winding protector. If the winding protector cuts out whilethe compressor is cold it may take approx. 5 minutes for the protector to reset. If the winding
protector cuts out while the compressor is hot (compressor housing above 80°C) up to 45 minutes may pass before the protector resets.
The winding temperature must never exceed 130°C.
Checking the winding protector
In the event of compressor failure a check must be made by resistance measurement directly on the current lead-in to find out whether the fault is due to motor damage or simply a winding protector trip.
Location of the winding protector in the electrical circuit.
1A: Main winding 1B: Start winding
1D: Winding protector
If resistance measuring or a test lamp shows that there is a connection through the motor windings from point M to point S, but a broken circuit between points M and C or S and C, this indicates that the winding protector has cut out.
Therefore, wait for the protector to reset.
12 – Service instructions
When emptying a defective system the refrigerant must be collected without mixing in other refrigerants.
Evacuation must take place until a vacuum of 1 mbar or lower is reached. Blow through the refrigeration system with dry nitrogen.
The drier must always be replaced when a system is opened.
Service on these installations must only be done by expert installers with thorough knowledge of inflammable gases like e.g. propane.
