7.2.1 Air Heat Exchanger Maintenance
Routine cleaning of air heat exchanger surfaces is essential to maintain proper operation of the unit, avoid corrosion and
rusting. Elimination of contamination and removal of harmful residues will greatly increase the life of the coil and extend
the life of the unit.
Remove surface dirt, leaves, fibers, etc. with a vacuum cleaner (preferably with a brush or other soft attachment rather
than a metal tube), compressed air blown from the inside out, and/or a soft bristle (not wire!) brush. Do not impact or
scrape the coil with the vacuum tube, air nozzle, etc.
Use of a water stream, such as a garden hose, against a surface loaded coil will drive the fibers and dirt into the coil.
This will make cleaning efforts more difficult. Surface loaded fibers must be completely removed prior to using low
velocity clean water rinse.
A monthly clean water rinse is recommended for coils that are applied in coastal or industrial
environments to help to remove chlorides, dirt and debris. It is very important when rinsing that the
water temperature is below 55 °C.
Galvanic corrosion of the connection Copper/Aluminum can occur in corrosive atmosphere under the plastic protection;
during the maintenance operations or periodic cleaning, check the aspect of the plastic protection of the
copper/aluminum connection. If it is inflated, damaged or took off contact the manufacturer representative for advice and
information.
7.2.2 Electrical Installation
All electrical maintenance activities must be followed by qualified personnel. Make sure the system is
switched off and the main switch of the unit open. Failure to observe this rule could result in serious
personal injury. When the unit is turned off, but the disconnection switch is in the closed position, the
unused circuits will still be active.
The maintenance of the electrical system consists of the application of some general rules as follows:
1. the current absorbed by the compressor must be compared to the rated value. Normally the value of the absorbed
current is lower than the rated value that corresponds to the absorption of the full load compressor at the maximum
operating conditions.
2. at least once every three months all the security checks must be made to verify their functionality. Each appliance,
with aging, can change its point of operation and this must be monitored to adjust it or replace it. The pump interlocks
and flow switches must be checked to make sure that they interrupt the control circuit if they intervene.
7.2.3 Service and limited warranty
All units are factory tested and guaranteed for 12 months as of the first startup or 18 months as of delivery.
These units have been developed and constructed according to high quality standards ensuring years of failure free
operation. However, the unit requires maintenance even during the warranty period, from the time of installation and not
just from the commissioning date. We strongly advise stipulating a maintenance contract with a service authorized by the
manufacturer to ensure efficient and problem free service, thanks to the expertise and experience of our personnel.
It must be borne in mind that operating the unit in an inappropriate manner, beyond its operating limits or not performing
proper maintenance according to this manual can void the warranty.
Observe the following points, to conform to warranty limits:
1. The unit cannot function beyond the specified limits.
2. The electrical power supply must be within the voltage limits and without voltage harmonics or sudden changes.
3. The three phase power supply must not have an unbalance between phases exceeding 3%. The unit must stay
turned off until the electrical problem has been solved.
4. No safety device, either mechanical, electrical or electronic must be disabled or overridden.
5. The water used for filling the water circuit must be clean and suitably treated. A mechanical filter must be
installed at the point closest to the BPHE inlet.
6. The value of the BPHE water flow must be included in the declared range for the unit considered, refer to the
CSS selection software.
