ELECTION

 

 

 

OF

 

 

 

LOCATION

 

The condensing unit should be installed in a location that meets the
following requirements:

 

1.

 

The foundation is strong enough to support the weight of the unit
and the floor is flat to prevent vibration and noise generation.

 

2.

 

The space around the unit is adequate for servicing and the
minimum space for air inlet and air outlet (see 

figure 2

  and

figure 3

) is available. 

 

3.

 

There is no danger of fire due to leakage of inflammable gas.

 

4.

 

The maximum level difference (20 m) between the condensing
unit and the air conditioning unit will not be exceeded.

 

5.

 

The piping length between the condensing unit and the air
conditioning unit may not exceed 35 m equivalent length.

 

6.

 

Select the location of the unit in such a way that neither the
discharged air nor the sound generated by the unit disturb
anyone.

 

7.

 

Make sure that the air inlet and outlet of the unit are not
positioned towards the main wind direction. Frontal wind will
disturb the operation of the unit. If necessary, use a windscreen
to block the wind.

 

8.

 

Make sure that the unit can be fixed directly in concrete or that
the optional floor standing kit is purchased in order to protect the
unit from being overturned by wind.

 

9.

 

The standard operation range of the ER-DA units ranges from
0°CDB to +43°CDB outdoor ambient temperature. However, the
allowable minimum temperature can be lowered to -15°CDB by
installing the head pressure control kit.

EFRIGERANT

 

 

 

PIPING

 

Always ensure to connect the pipe end to the appropriate measures
(mm or inch).

Refer to the technical specifications for the required diameter for both
liquid and gas lines.

 

Precautions when handling refrigerant piping

 

If air, moisture or dust gets in the refrigeration circuit, problems may
occur. Therefore, always take into account the following when
connecting the refrigerant piping:

 

1.

 

Use clean and dry pipes only.

 

2.

 

Hold the pipe end downwards when removing burrs.

 

3.

 

Cover the pipe end when inserting it through a wall so that no
dust and dirt enter.

 

4.

 

In case of flare connections, flare the pipe end neatly to avoid
refrigerant leaks.

 

Connecting the refrigerant piping

 

Piping connections must be made from the front of the condensing
unit (refer to 

figure 1

).

The liquid line must be connected to the condensing unit via a flare
connection. In case of an ER5-8-10, the gasline must be connected
to the unit using a flange connection. Do not forget to install the
gasket delivered with the manuals. In case of an ER3DA unit, both
the liquid line and the gas line must be connected to the condensing
unit via a flare connection. 

Follow the instructions supplied with the air conditioner to connect
the piping to the air conditioner side.

For the ER3DA unit, the refrigerant gas inlet must be changed from 5/
8" pipe to 3/4" pipe if the equivalent length exceeds 20 meters. This
to improve the cooling capacity of the unit. 

 

The head pressure control kit must be installed by a
licensed refrigeration technician and must be in accord-
ance with the installation instructions and wiring diagram
supplied with the kit.

 

A liquid line and gas line must be provided between the
condensing unit and the air conditioning unit and must be
installed by a licensed refrigeration technician. All field
piping must comply with relevant European and national
regulations.

 

NOTE

 

If the piping length between the condensing unit and
the air conditioner exceeds 8 m, additional refrigerant
R22 must be charged after vacuum drying of the
installation as described further.

Leak test and vacuum drying of the refrigerant piping

 

After connection of the piping at both the condensing unit and air
conditioner side, a leak test must be performed and the air in the
refrigerant piping must be evacuated to a value of 3 mbars absolute
by means of a vacuum pump.

 

Required equipment:

External pressure source with pressure gauge and pressure
regulator (e.g. N2 - nitrogen cylinder)

Gauge manifold (class 1,0)

Vacuum pump

Procedure 

(see 

figure 4a

 and 

figure 4b

):

1.

Keep the gas line stop valve (1) and the liquid line stop valve (2)
closed.

2.

Connect the high pressure valve of the gauge manifold (3) to the
service port of the liquid line stop valve (4) and the low pressure
valve of the gauge manifold (5) to the service port of the gas line
stop valve (6).

3.

Connect the N2 cylinder (7) to the gauge manifold.

4.

Make sure that the cylinder valve (8) and the regulating valve (9)
are closed.

5.

Open the N2 cylinder valve (8) and the pressure valves of the
gauge manifold.

6.

Pressurise the circuit up to 20 bar by opening the regulating
valve (9) of the N2 cylinder stepwise.

7.

Close the low pressure valve (5) and pressurise the liquid side
up to 28 bar.

8.

Close the cylinder valve (8) and the high pressure valve of the
gauge manifold (3).

9.

Loosen the charge hose to release its pressure.

10. Close the regulating valve (9) completely.

11. Remove the charge hose from the manifold.

12. Check the connections marked with  for leakage. Apply soap-

suds to the connections and inspect carefully. After checking
wipe them off completely.

13. Release the pressure of the circuit by opening the pressure

valves.

If the piping length between the condensing unit and the air
conditioner exceeds 8 m, additional refrigerant R22 must now be
charged: follow the procedure given in 

"Refrigerant charge"

.

Otherwise, continue with step

14.

 below.

14. Connect the gauge manifold to the vacuum pump (10).

15. Start the vacuum pump.

16. Check that the low pressure gauge pointer stabilises and

indicates a constant level (3 mbars).
Try to reach perfect vacuum (gauge reading - atmospheric
pressure 1013 mbars).

17. Close the pressure valves of the gauge manifold.

18. Stop the vacuum pump.

19. Disconnect the vacuum pump from the gauge manifold.

20. Remove the blind cap from the gas line stop valve (11) and the

liquid line stop valve (12).

21. Loosen the gland packing retainers of the gas line stop valve

(11) and the liquid line stop valve (12) using a hexagon wrench.

22. Partially open the gas line stop valve and the liquid line stop

valve and wait until the pressure indicated by the low pressure
gauge pointer equals the pressure indicated by the high
pressure gauge pointer.

23. Fully open the gas line stop valve and the liquid line stop valve.

24. Remove the hoses between the gauge manifold and the

condensing unit.

25. Check the stop valves for leakage.

Refrigerant charge

If the piping length between the condensing unit and the air
conditioner exceeds 8 m, additional refrigerant R22 must be charged:

Required equipment:

R22 refrigerant cylinder

Balance

Gauge manifold

T-joint

Shut-off valve

Procedure 

(see 

figure 5a

 and 

figure 5b

):

1

Place the R22 refrigerant cylinder (1) upside down and connect
it, together with the vacuum pump (2), to the gauge manifold (3)
using a T-joint (9).
