11.  MAINTENANCE

11.2  Special maintenance 

Special maintenance involves all those operations that are performed 
on a one-off basis in the event of malfunctions or breakages of certain 
components. 
The following components are those susceptible to breakage:

• 

solenoid valves

• 

pressure reducer

• 

pressure switches

• 

pump motor

• 

pump

• 

electronic controller

• 

fuses

• 

nozzles

• 

nozzle manifold

• 

fans on the blower units

To replace these contact specialist and authorised personnel. 
To find the replacement part number, see the paragraph "Cabinet spare 
parts"   

11.3  Pump maintenance

The pump is the most complex mechanical device inside the cabinet, as 
well as the heart of the high pressure system.It therefore requires regular 
maintenance, involving the operations described below.

11.3.1  Oil change

Important:

 after the first 50 hours of operation, the oil in the pump needs 

to be changed (P/N 5024646AXX). Failure to change the oil after the first 
50 hours may cause damage to the pump and reduce its working life. 
The first oil supplied, in fact, will accumulate debris due to transport and 
commissioning, and a longer operating time cannot be guaranteed.

Important: 

change the pump oil after the first 50 hours of operation.

Important: 

if there are no leaks or faults, when the "1000 h" check 

warning is shown, the oil change may be postponed.

In normal operating conditions, except for the first oil change oil after 50 
hours, it is recommended the change the oil every 3000 operating hours. 
Every 1000 hours, a warning is generated by the electronic controller, 
while the 3000 operating hours are signalled by the electronic controller 
via the "3000 hour maintenance" alarm on the display.

To change the oil, follow the sequence described below (with the unit off 
and the water line closed):

1. 

Remove the yellow cap on the top of the pump and unscrew the oil 
drain plug attraction the bottom (steel hexagonal plug). 

2. 

Empty the oil into a suitable container. Close the plug. 

3. 

Dispose of the oil in accordance with local standards. 

4. 

Fill the pump body with SAE 15W40 mineral oil, up to the level 
suggested by the circular marker on the side of the pump (the 
required oil content is around 350 ml).

5. 

Finally, close the yellow cap on the top of the pump. 

11.1  Routine maintenance

Routine maintenance is recommended every three months, and mainly 
involves visual inspection of correct operation of the main components. 

The following is a list of recommended operations:

• 

Check water inlet filter. 

It is recommended to change the filter cartridge once every 6-12 months. 
To change the cartridge, switch the unit off and close the feedwater line. 
Empty the filter using the small tap at the bottom. Unscrew the white 
holder from the nut at the top using the tool provided. Remove the filter 
cartridge inside and fit a new one (P/N ECKFILT050). Tighten the holder, 
ensuring that the O-ring is still in good condition to ensure tightness. 
Close the tap under the holder and open the feedwater line.          

• 

Check pump oil level. 

To check the level visually, use a mirror that allows a view of side of the 
pump facing to the cabinet wall. There is a small mark behind a circular 
transparent Plexiglas cover. The oil level is correct if, with the unit off, it 
remains around the central circumference. If the level is lower than the 
minimum shown in the figure, top up with oil to the correct level (oil P/N 
5024646AXX).
Generally the oil level should remain constant and periodical top ups 
should not be needed. If oil leaks are found, contact CAREL.

Fig. 11.a

• 

Check the nozzles: make sure the spray cone from the nozzles is 

regular. 

Even when using demineralised water, some particle may at times 
build-up on the nozzle opening, making the spray cone less uniform 
and affecting absorption efficiency. If this happens, remove the nozzle 
(unscrew using a 10 mm spanner) and clean it (immersing in acetic acid 
tom remove scale) or replace it (P/N UAKMTP%000). Before assembling 
the nozzle again, remove the residual Teflon from the thread and the 
small white filter at the base of the nozzle, and apply the sealant again to 
ensure water tightness.    

• 

Check the fans

Make sure that all of the fans on the blower units are working. In the 
event of malfunctions, check the power supply wiring. If the wiring is OK, 
replace the fan.  

• 

Check 

that there are no water leaks inside cabinet and on the 

distribution line and fittings.
