3 – Installation

Installation, maintenance and commissioning must be carried out by qualified specialists only! All connections, i.e. solderings and flare joints, are to be made professionally.

Protect the surroundings against admittance of unauthorised persons. Pay attention to sufficient ventilation.

Remove transport safety devices, if any. Mount the condensing unit horizontally. Use the correct tube diameters.

Prevent any vibrations. Avoid smoking and open fire.

Refrigerant is to be removed and disposed of professionally.

Assembly of the condensing units

Prepare the tube connections from the evaporator.

It is recommended to use a drier with 3Å molecular sieves, e.g. Danfoss type DML.

Use only dry components and avoid moisture entering the system.

The system components must not contain any chlorine, mineral oil, or other oily substances. Maximum test pressure must not exceed 32 bar.

4 – Refrigerant charging

2.Discharge stop valve

3.Connection to suction side

4.Shut-off valve to vacuum pump

5.Shut-off valve to charging cylinder

6.Connection to discharge side

7.Shut-off valve to discharge side

8.Shut-off valve to suction side

9.Connection to vacuum pump

10. Connection to charging cylinder

When a vacuum of 0.5 mbar or lower has been reached, shut off the connection to the vacuum pump by closing all manifold valves.

Repeat the evacuating process once or twice if necessary and then close all manifold valves. Close the service connector of the suction stop valve (1) by turning the spindle„anticlockwise“ to the rear stop.

Refrigerant charging must take place from equipment not contaminated with refrigerants containing chlorine.

For units with stop valves the rule is that refrigerant should always be charged in liquid form through the discharge stop valve of the unit in order to avoid liquid hammer when the unit is started. If this rule cannot be observed the compressor is not to be started until the pressure and the temperature of the refrigerating system have been equalized. Open valves (5) and (7) of the valve manifold while keeping the other valves closed.

When all liquid has been transferred to the discharge side of the unit close the service connector of the discharge valve (2) by turning the spindle„anticlockwise“ to the rear stop. Remove all hose connections.

Fit the union nuts with blind caps on pressure gauge connectors (1) and (2).

Fit and tighten up caps on the valve spindles.

10. Connection to charging cylinder

Connect the discharge line to the suction stop valve (1) of the unit.

Connect the suction line, via the filter drier, to the discharge stop valve (2).

Make the connection (3) between the manifold and the service connector of the suction stop valve (1).

Make the connection (6) between the manifold and the service connector of the discharge stop valve (2).

Make the connection (9) between the vacuum pump and the manifold (4).

Make the connection (10) between the charging cylinder and the manifold (5). Remove the protective caps from the spindles of both stop valves (1) and (2).

Open valves (4), (7) and (8). Open stop valves (1) and (2) to mid position. Start the vacuum pump. Vacuum pumps, which are normally used for refrigerants containing chlorine, cannot be used with R134a, R404A/R507 and R452A.

Only a vacuum pump with special Polyolester oil may be used for systems with refrigerant containing FCKW, HFCKW and HFKW. (Contact the pump supplier.)

Evacuation (T0, A00)

Evacuation takes place through the compressor then process connector after complete connection in the refrigerating circuit.

Plan sufficient time for the evacuation as it takes place from the low pressure side only, unless additional measures were taken to speed up the evacuation.

Vacuum pumps normally used for refrigerants containing chlorine must not be used with R134aand R404A/R507. Only a vacuum pump with special Polyolester oil may be used for systems with refrigerant containing FCKW, HFCKW and HFKW. (Contact the pump supplier.)

6 – Electrical connections

Prepare the electrical connections while evacuation is taking place. Do not start the compressor until the vacuum has been broken. Remove the cover over the terminal board. Connect the leads.

It is impossible to start the unit without a thermostat (1H) being connected or a lead between 1 or 2, respectively, and L has been established (fig. 4-7).

8 – Safety

Important service and safety tips

The drier must always be replaced when a system has been opened.

Blow through the system with dry nitrogen before soldering.

When a defective system is emptied the refrigerant must be collected without mixing with other refrigerants, and the refrigerant must not leak into the environment.

(See also “Installation“).

The condenser and the complete condensing unit must be cleaned regularly.

Specified maintenance and cleaning intervals must be observed.

Working on components that are under pressure is dangerous.

Beware of hot and extremely cold components. Beware of moving components (e.g. fan).

Pay attention to sufficient ventilation. Check the perfect operation of the fan. The application limits stated by the manufacturer must be observed.

If pressure controls are specified, they must be installed professionally.

The operating condition must be monitored in

order to ensure perfect operation.

Check whether the shut-off valves (suction and discharge side) are completely opened. Ensure that EN 378 is observed.

If forced ventilation is necessary, this is to be clearly shown (i.e. by a label).

Do not install in aggressive, moist or dusty environment.

Do not install or start in rooms containing flammable gases or in installations operating with such.

PED (Pressure Equipment Directive 97/23EC)

Condensing units are no„units“ in accordance with the PED.

The unit/installation into which the condensing unit is mounted/integrated, must be in accordance with the PED.

9 – Maximum refrigerant charges

Units with receiver. See fig. 9.

Units without receiver. See fig. 10. The refrigerants stated on page 3 and 4 must be used.

It is recommended that only the right quantity of refrigerants necessary for correct function of the refrigeration system be added.

For refrigeration systems with capillary tube the charge must be adapted to suit each system type.

The operating charge must never exceed the capacity of condenser and receiver.

Always avoid excess refrigerant charge!

Crankcase heater

If the maximum amounts of refrigerant cannot be observed in T0, T2, A01, A02, A04 or T0 condensing units respectively, a crankcase heater or a„pump-down transmission“ must be used. The crankcase heater must be fitted directly over the weld.

The crankcase heater will heat the compressor oil during standstill periods. When the refrigeration system has been at a stand-still for longer periods the crankcase heater must be cut in 2-3 hours before starting. The following

crankcase heaters are recommended TL and FR: 35 W (code no. 192H2095) SC: 55W (code no. 192H2096)

10 - Cold start

After installing the unit the compressor must be allow-ed 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.

See also„crankcase heater“. Never start during vacuum!

11 - Winding protector

The compressors have a built-in winding protector. If the protector cuts out while the 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.

Checking the winding protector

In the event of a compressor failure a check must be made by resistance measurement direct on the current lead-in to find out whether the fault is due to motor damage or simply a winding protector trip.

Fig. 3. Location of the winding protector in the electrical circuit.

1A.Main winding

1B. Start winding 1D.Winding protector

If resistance measuring shows that there is a connection through the motor windings from points K and S of the current lead-in, but a broken circuit between points K and F or between S and F, this indicates that the winding protector has cut out. Therefore, wait for the protector to reset.

Når et vakuum på 0,5 mbar eller derunder er nået, afbrydes tilslutningen til vakuumpumpen ved at lukke alle manifoldventiler.

Gentag tømningsprocessen en eller to gange, hvis det er nødvendigt, og luk derefter alle manifoldventiler. Luk servicetilslutningen

til sugestopventilen (1) ved at dreje spindlen mod uret til bagerste stopmærke. Kølemiddelpåfyldning skal foretages fra udstyr, der ikke er forurenet med kølemidler, der indeholder chlor.

For aggregater med stopventiler er reglen, at kølemidlet altid skal påfyldes i væskeform gennem trykstopventilen på aggregatet for at undgå væskeslag, når aggregatet startes. Hvis denne regel ikke kan overholdes, startes

kompressoren ikke, før trykket og temperaturen i kølesystemet er trykudlignet.

Åbn ventilerne (5) og (7) på ventilmanifolden, samtidig med at de andre ventiler holdes lukkede.

Når al væske er overført til aggregatets trykside, lukkes servicetilslutningen til afgangsventilen

(2) ved at dreje spindlen mod uret til bagerste stopmærke. Fjern alle slangetilslutninger. Sæt blindhætter på omløbermøtrikkerne

på manometertilslutningerne (1) og (2). Monter og spænd hætter på ventilspindlerne.

10. Tilslutning til påfyldningscylinder Tilslut trykledningen på sugestopventilen

(1) på aggregatet.

Tilslut sugeledningen, via filtertørreren, på trykstopventilen (2).

Foretag tilslutningen (3) mellem manifolden og servicetilslutningen på sugestopventilen (1). Foretag tilslutningen (6) mellem manifolden og servicetilslutningen på trykstopventilen (2). Foretag tilslutningen (9) mellem vakuumpumpen og manifolden (4).

Foretag tilslutningen (10) mellem påfyldningscylinderen og manifolden (5). Fjern beskyttelseshætterne fra spindlerne

på begge stopventiler (1) og (2). Åbn ventilerne (4), (7) og (8). Åbn stopventilerne (1) og (2)

til midterposition. Start vakuumpumpen. Vakuumpumper, der normalt bruges

til kølemidler, der indeholder chlor,

må ikke anvendes sammen med R134a, R404A/R507 og R452A. Der må kun bruges en vakuumpumpe med speciel

polyolesterolie til systemer med kølemiddel, der indeholder FCKW, HFCKW og HFKW (kontakt pumpeleverandøren).

Tømning (T0, A00)

Tømning fortages gennem kompressoren og derefter processtudsen efter komplet tilslutning i kølekredsløbet.

Planlæg tilstrækkelig tid til tømningen, da den kun foretages fra lavtrykssiden, medmindre der tages yderligere skridt til at sætte fart på tømningen.

6 – Elektriske tilslutninger

Klargør de elektriske tilslutninger, mens tømningen foretages. Start ikke kompressoren, før vakuummet er brudt. Fjern dækslet over klemrækken. Tilslut ledningerne.

Det er umuligt at starte aggregatet, uden at der er tilsluttet en termostat (1H) eller en ledning mellem henholdsvis 1 eller 2, og L er blevet etableret (fig. 4-7).
