1. PRELIMNARY CAUTIONS
These Operator Instructions must be kept in good preservation conditions, in a place easily
accessible to the appointed personnel. These Operator Instructions are not exempt from
compliance with the laws in force regarding safety and on-the-job injury protection regulations.
ONDA S.p.A. SHALL NOT BE LIABLE in the case of:
improper use of equipment under pressure;
alterations of the equipment under pressure;
non-compliance with safety regulations in force;
non-compliance with the content of these Operator Instructions.
2. INTRODUCTION
The plate exchangers are composed of a pile of corrugated plates, stacked onto each other
between two closure plates. The pile of plates is subjected to a process of brazing with the
forming of two separate circuits.
3. MATERIAL DELIVERY
Before carrying out any operation on the exchanger, check the correspondence between the
ordered machine and the received one. Please also verify that the model of the exchanger has
been adequately sized with the ONDA selection programme for the type of application.
3.1 Enclosed documents
These Operator Instructions are always enclosed with the exchanger.
4. HANDLING AND TRANSPORTATION
LIFTING AND TRANSPORTATION MANEUVRES MUST BE
PERFORMED BY QUALIFIED PERSONNEL
The plate exchanger includes attachments that protrude from the space occupied by the
equipment under pressure. It is therefore recommended to handle with maximum care to prevent
any impact or damage to the protruding parts.
Before handling the exchanger, it is necessary to verify the size and weight of the exchanger,
written to allow the choice of an adequate lifting system.
A steel or synthetic fibre lashing must be used, with payload exceeding the weight of the load to
be handled.
For exchangers of particular dimensions, please use the eyebolts specifically required for the
exchanger:

6
- A eyebolts in horizontal position
- B eyebolts in vertical position, lifting from horizontal to vertical position
- C eyebolts in vertical position, lifting from vertical position
CAUTION: DO NOT HANDLE THE EXCHANGER WHEN IT IS
UNDER PRESSURE
5. INSTALLATION
5.1 CONNECTIONS:
In standard versions (one side with cooling circuit), the exchangers consist of 4 connections
(F1, F2 e W1 W2) in the anterior part of the exchanger.
Additional connections can be present in the posterior part of the exchanger (BF1, BF2 e
BW1 BW2)

7
In the case of double-circuit plates (two circuits on cooling side), the connections of the 2 cooling
circuits F1/F2 and G1/G2 are on the same side, while on the opposite side there is the circuit for
the secondary fluid (W1 and W2).
On the side with the cooling connections, there are additional connections BW1 and BW2 which
can be used for temperature probes.
Depending on the type of application, the Onda plate connections may be of the following types:
threaded internally (ISO-G), with flexible joint (Victaulic) or welded.
The Onda standard plates of the gas-water type include attachments on the gas side of the
welded type.

8
For threaded attachment, avoid excessive tightening of the connections. Excessive force
may ruin the brazing where the connection is placed.
For welded connections:
- Wrap a wet cloth at the base of the connection where the welding is done
- Use alloys containing an amount of silver over 40%.
5.2 FILTERS:
Install a filter higher than the exchanger to prevent particles and suspended solid materials from
entering the exchanger carried by the fluid. Clogging the canals may cause reduced performance,
an increase in load leaks and an increase in the risk of freezing. Select the filter keeping in mind
the minimum and maximum workload values of the exchanger.
Caution! Use a straining filter with passage holes not exceeding 90 mm.
5.3 ASSEMBLY FOR WATER-WATER APPLICATION
For applications of the type water-water, in order to obtain optimal performance conditions,
connect so that the flow of fluids is against the current, as shown in the illustration:
5.4 ASSEMBLY FOR APPLICATION WITH COOLANTS
For applications with coolants, install the exchanger in a vertical position.
OUT
OUT
IN
IN

9
For standard exchangers, the cooling circuit includes attachments at the left of the plate (F1
and F2). The water circuit attachments are positioned on the right (W1 and W2)
- USE OF EVAPORATOR TYPE:
Connect the cooling circuit and the water circuit as illustrated below: cooling entrance on the
lower left side and water entrance on the upper right side.
Expansion valve:
Place the expansion valve where the entrance attachment of the liquid coolant is. The
valve must be of capacity slightly higher than that of the unit and the sensor located in
the suction line should be isolated from the room temperature and sufficiently sensitive
to quickly respond to variations in gas temperature. When choosing an expansion valve,
please consider load leaks on the coolant side.

BRAZING-WELDING PROCEDURE
- Degrease and burnish the surfaces to be welded
- Insert the copper pipes into the connection, holding it in position and
solder using a silver alloy of at least 45%.
- Do not direct the flame onto the exchanger.
- Use a wet cloth to prevent overheating of the exchanger.
- During welding of the exchanger, protect the interior of the circuit with a
nitrogen flux to prevent oxidation.
CAUTION: excessive heating of the exchanger during brazing may cause the melting
of the copper inside the plates and bring irreparable damage.

CORRECT INSTALLATION OF THE EXPANSION VALVE IN THE EXCHANGER

11
MAXIMUM DISTANCE 50 CM –MAXIMUM DISTANCE 30 CM
- USE OF CONDENSATOR TYPE:
Connect the cooling circuit and water circuit as illustrated below: cooling entrance on the
upper left side and water entrance on the lower right side for single-circuit exchangers. For
double-circuit exchangers, the cooling entrance on the top and water entrance on the
bottom, with exit on the opposite side.
For all uses:
Avoid using quick-closure valves to prevent sudden flow interruptions and water
hammers
To prevent fatigue breakage of the exchanger, avoid excessive temperature and
pressure fluctuations by using suitable adjustment systems.
Verify compatibility between the fluids and the construction materials of the
exchanger.
5.5 Protection from vibration
Vibration coming from the system could damage the exchanger. Include flexible connections or
dilation compensators to prevent vibrations, pulsations and strain from transmitting to the
exchanger.
5.6 Isolation
Depending on the type of application, please isolate the exchanger.

6. USE
For correct functioning:
DO NOT EXCEED THE MAXIMUM APPLICABLE LLIMITS IN
TERMS OF PRESSURE (PS) AND (TS) SHOWN ON THE DATA TAG
Use anti-freezing solitions in the case in which the evaporation point is
close to the freezing point of the liquid, after verifying its compatibility with
the construction materials of the exchanger.
FOR USE WITH COOLANTS
oUse a thermostat with anti-freezing protection and a system for checking the
flow to ensure constant water supply before, during and after the functioning of the
compressor.
oThe exchanger must be equipped on the secondary fluid side with a
temperature sensor so that the secondary fluid is at least 2K greater than its
freezing point.
oIf the secondary fluid is absent, immediately switch off the compressor.
oWhen the evaporation point of the fluid is lower than the freezing temperature
of the secondary fluid, there is risk of freezing. If the coolant consists of a bland,
there is risk of freezing, when the bubble point in the exchanger is lower than the
freezing temperature of the secondary fluid.
oIf water is the secondary fluid, there is risk of freezing if the temperature is
equal or less than 0°C (32°F).
oMake sure the secondary fluid flows inside the exchanger before starting the
compressor.

13
oMake sure that the secondary fluid continues to flow inside the
exchanger even after turning off the exchanger and while the pressure of
the coolant is high enough to prevent freezing of the secondary fluid.
oWhen the machinery is started, the temperature corresponding to the
pressure of the coolant inside the exchanger must not be lower than the
freezing point of the secondary fluid.
oWhen the machinery is stopped, the temperature corresponding to the
pressure of the coolant inside the exchanger must not be lower than the
freezing point of the secondary fluid.
oTo prevent freezing phenomena with damage to the exchanger, do not pump-
down the evaporator after turning it off: in other words, avoid using the compressor
to achieve the set coolant pressure.
oDo not expose the exchanger to strong, sudden variation in pressure.
oDuring the shutdown phase of the exchanger, once the compressor has
stopped, maintain the functioning of the pump for at least 5 minutes to prevent any
freezing occurrence.
oDuring the start-up phase, switch on the pump at least one minute before
starting up the compressor to prevent any freezing occurrence.
7. MAINTENANCE AND USER CHECKS
DO NOT OPEN THE EXCHANGER WHEN IT IS UNDER PRESSURE.
WATER CIRCUIT CLEANING:
In case of particularly hard water with a tendency to form deposits, it is possible to clean the
exchanger through CIP (Cleaning In Place). There may be a decrease in performance due
to the presence of deposits inside the exchanger. In such cases, force-wash using a
suitable descaling chemical solution, after checking the compatibility with the construction
materials of the exchanger.

14
Chemical washing must be carried out inside the water circuit; pump the chemical solution
in the opposite direction to the one in the normal operation of the circuit.
For optimal cleaning, the flow of the descaling product should be at least 1.5 times greater
than the normal flow used.
Do not clean circuits working with cooling gas.
Cleaning must be performed by specialised personnel.
Always rinse the circuits with fresh water after chemical washing.
8. SAFETY
Always install safety accessories compliant to the national regulations of the country of use;
a fire for external causes will provoke the exceeding of admissible limits for pressurised
equipment.
Do not expose pressurised equipment to any impact during functioning.
Do not weld on the equipment body under pressure.
Do not use the pressurised equipment for uses that differ from what is prescribed.
In case of leak detection, immediately switch off the functioning exchanger.
9. DISPOSAL
This pressurised equipment contains recyclable materials: when the machinery stops functioning,
please enquire on the current regulations in your country on the matter of recycling.
