Maintenance

Caution

Maintenance of the Topvex SoftCooler is of great importance for the whole installations environmental
influence, operating economy, durability, security and functions.
Read the Warnings chapter and Refrigerant Control/Reporting chapter before doing any work on the
SoftCooler unit.

Maintenance should be carried out two times a year, apart from general cleaning the following should be done:

1.

Leakage control with registration (Legal requirements: at least 1 time a year)

Different regulations can be valid in different countries. Check with your local government.

2.

General control.

When unit is running listen for abnormal sounds and vibrations. Inspect occurrence of oil leakage (can be a symptom
on refrigerant leakage). Inspect occurrence of corrosion, fretting damages, loosen pipe suspensions.

3.

Control of the cooling coil (evaporator coil) and condenser coil.

After a long time of use the coils can obtain a deposit that obstructs the heat transfer and airflow. Vacuum clean the
coils carefully from the dirty side.

4.

Control of the drip tray.

After a long time of use the drip tray and the drain can obtain a deposit that obstructs the drain of the condensation
water. Clean the drip tray, drain, water seal and pipes from dirt and deposits.

5.

Control of the air filter for the frequency converter.

The filter is located in the inspection door. After a long time of use the filter can be clogged so that the cooling airflow
decreases and thereby causes a to high temperature for the frequency converter which results in operational disturb-
ance. Loosen the filter from outside of the unit (snap locking of the cover), if the filter is dirty exchange it with a new
(filter mat G5).
