Adjustment

The EURV heat exchanger is adjusted and tested at the

time of delivery. No adjustments are normally required,

therefore.

Cleaning

The presence of dust on the heating and cooling surfaces

will result in impaired heat transfer. The finned body

must be kept clean, preferably by vacuum cleaning or

careful blowing with compressed air, moving parallel with

the fins. The use of ULCZ-01 cold degreasing agent is

recommended where the dust is mixed with grease.

After cleaning:

Remove all fallen dust

and/or liquid before

starting the fan

Important!

Clean the water trap,

if fitted

Charging the system

If the pressure is below 0.01 MPa, the system requires

charging with heat transfer medium. This is done by

pumping pre-mixed heat transfer medium (30% ethyle-

ne glycol) into the charging valve (8 in Fig. 2) until the

manometer reads 0.1 MPa.
