Start up

After all components are

connected and tested, the system

can be put into operation. To

ensure proper function, a function

test should be made to recognize

any irregularities during operation

of the units before transfer to the

client.

Function test and test run

Check the following points.

■

Leak tightness of refrigerant

lines.

■

Even run of compressor and

fan.

■

Discharge of cold air on the

interior unit and heated air on

the exterior unit during cooling

operation.

■

Function test of the interior unit

and all program runs.

■

Check of the surface

temperature of the suction

line and determination of

evaporator overheating. To

measure the temperature, hold

the thermometer to the suction

line and subtract the boiling

point temperature reading on

the pressure gauge from the

measured temperature.

■

Documentation of the

measured temperatures in the

start up protocol.

Function test of Cooling

operating mode

1. Remove the caps on the valves.

2. Start operation by opening

the blocking valves of the

exterior unit momentarily until

the pressure gauge shows a

pressure of approx. 2 bar. .

3. Check all connections for leaks

with leak detection spray and

suitable leak detectors.

4. If not leaks are found, open the

blocking valves by turning them

in counterclockwise direction

with a hexagon wrench to the

stop. If leaks were found, draw

off the refrigerant and rework

the defective connection. In

this case, a new vacuum and

drying procedure is imperatively

required!

5. Turn the main switch on the

building or the fuse on.

6. Turn the unit on via the remote

control and select the cooling

mode, maximum fan speed and

lowest nominal temperature.

7. Measure all required values,

record them in the start up

protocol and check the safety

functions.

8. Check the unit control with

the functions described in

chapter „Operation“.

Timer, temperature setting, fan

speed and change between air

circulation or dehumidiﬁcation

mode.

9. Check the function of the

condensation line by pouring

distilled water into the

condensation pan.

To do so, use a spout to guide

the water into the condensation

pan.

10.

Switch the interior unit to

cooling mode.

11.

Check all regulating, control

and safety devices for function

and correct adjustment during

the test run.

12.

Check the control of the

interior unit with the functions

described in the operating

instructions

(Timer, temperature

adjustments and all mode

settings).

13.

Measure the overheating,

external, internal, discharge and

evaporator temperatures and

record the test data in the start

up protocol.

14.

Remove the pressure gauge

and install the caps.

The start up may only be

made by especially trained

technicians and must be

documented accordingly.

NOTE

Due to the turn on delay, the

compressor will start up a few

minutes later.

NOTE

Then check the blocking valves

for leaks.

NOTE

Final tasks

■

Reinstall all parts which were

removed.

■

Familiarize the operator with

the system.
