14.0 Maintenance
•
Condenser Fins:
Condenser fins become dirty over time as ambient air is induced to the condenser. Dirty
coil surfaces result in high condensing temperatures and poor unit performance. Regular
cleaning is recommended, the frequency of doing so being dependent on the installation
and the surrounding environment .but as a general guide it is advisable to do this at least
Once Per Two Months.
As a general rule, and for a clean environment we would recommend the fins be cleaned
with liquid detergent diluted with clean water. The ZX has a well designed chassis with
falling levels towards a large drainage hole and provided the unit is installed level, any
cleaning solution should be able to drain away. A light brush downward (in the direction of
the fins) should be done before washing to remove heavy deposits.
Warning: Do not use acidic solutions to clean the coil.
After cleaning, the fins should be brushed lightly with a proper fin comb (13 FPI).

Electrical Connections:
All condensing units generate vibration of some degree. The ZX is no exception except the
vibration levels from the compliant scroll technology is less severe than units employing
reciprocating compressors. Because of this, the ZX can be mounted on simple, less
expensive rubber strips. Over time however and also due to temperature extremes within
the unit housing electrical terminations can come loosened.
It is suggested that the main electromechanical terminations be checked for tightness at
least
Once Per 6 Months.
The main terminal strip and compressor contactor are the most
likely components to be effected by vibration.
WARNING!
Make sure this work is not undertaken with out firstly turning off the unit isolating switch!
Most of the control wiring (and terminations) are low voltage connections and should not
be effected in the same way as the heavier electro-mechanical terminations. Most
terminations are of the crimped type and inside plastic plugs. Visual inspection
once per
half year
should be sufficient for these terminations.

E2 Control Panel
This is a fixed PCB ( Printed Circuit Board) and other than the terminations mentioned in
the previous section, the panel itself is not a routine maintenance item.
It does have one fuse as protection and the wiring diagram provides a guide to its location
