Lubrification - Onda EKC Manuel D'emploi

The voltage of defrosting resistance is max 240 V. Heating
elements can be connected in series between 2 phases
(see drawing). Also the mass is to be included in the
power supply. All the elements can be easily disassembled,
the elements of the discharge collecting tank can be
disassembled after removing the discharge collecting tank.
Electrical defrosting terminal blocks are fitted with wiring
diagrams. If the terminal block wiring diagram is not
provided, please contact the supplier.
HOT GAS DEFROSTING
Our heat exchangers are designed to be defrosted by using
gas under pressure. Gas defrosting requires hot gas supply
by means of a priming tank. The installer must ensure that
hot gas defrosting is sufficient.
WATER DEFROSTING
Defrosting water must have a neutral pH and must be
filtered. The machine drawing indicates the quantity of
water nevessary for this procedure. it is necessary to
set the quantity of water before the initial start-up. The
discharge collecting tank will be full in case of a high water
volume. Water temperature must be between min.15°C and
max.30°C.
FROST REMOVAL BY MEANS OF
COMPRESSED AIR
During this procedure, it is necessary to avoid frost or ice
formation which can damage the heat exchanger.
After the initial start-up, heat exchangers don't require
any particular maintenance. However, we recommend to
inspection regularly heat exchangers (i.e. the ventilator
fixing, electric cables, the main structure to check corrosion,
the suction side to check if blades are clean).

Heat exchangers can be washed or cleaned with cleansers.
Watch out: don't let the ventilator motor, terminal blocks
and electrical cables become wet. Don't use aggressive
cleansers. We also advise to use a cleanser with a 6-8
PH. After washing rinse completely the surface. Heat
exchangers blades mustn't be deformed while cleaning.
You can clean finned packs with any food industry
cleansers not exceeding appropriate doses. The maximum
temperature of washing water is 90°C (Caution: the
maximum pressure of the refrigerating system must not be
exceeded; after washing, rinse carefully finned packs with
water having a neutral PH.
Fan motors must be regularly checked to verify their fixing,
if they are clean and possible vibrations..
Disconnect the power supply before
performing any procedures on fan motors.
If heat exchangers haven't worked for a long period, it is
necessary to perform the same maintenance on fan motors
which would be necessary when stored.
Lubrification is necessary only if it is explicitly indicated on
the ventilator.
COATING / ANTICORROSION PROTECTION
Heat exchangers fitted with coating cannot be used with
unpackaged products. ONDA provides heat exchangers
with coating, only on-demand of the installer/final user.
Coating warrantly is only provided if heat exchangers are
regularly controlled and subject to adjustments. A 2-year-
coating warranty is provided when more that 5% of the
cured surface separates, if inspections and maintenance is
performed carefully.
