Electric Heater - CIAT Climaciat Instruction Manual

10.4.1 Cooling coil
ƒ Maintenance:
- Make sure the water inlet and outlet ducts are in good condition. Check the tightness of the connections and retighten if
necessary.
- If the coil is not operating, we recommend bleeding it fully. Blow all the circuits with compressed air to bleed them fully.
Without this additional pressure, significant amounts of fluid may remain, posing a serious risk of damage in the event of
freezing (not covered by the warranty).
- If the fins are damaged, straighten them using a comb.
- For glycol/water mix heat exchangers, check the level of frost protection using a refractometer.
- Cleanliness is a determining factor in the unit's performance, therefore carefully check the condition of the coil, the
corrosion level and for any damage.
- - The coils can be cleaned without being disassembled. However, if they are not easily accessible, or if the fouling level is
excessive, the coils are positioned on runners and can be removed for complete cleaning or replacement.
ƒ Assembling and disassembling the coil:
- Remove the front panel, then the mounting screw (detail A) to remove the coil.

ƒ Coil maintenance
- If the fins are damaged, straighten them using a comb.
- Instruction in case of low fouling level (non-clogging dust or dry residue)
- Counter-flow supply air: dry air up to 30 bar.
- Where possible, periodically reversing the flow of air generated by the fans can prevent this.
- In the event of moderate fouling (moderate clogging due to dry residues, damp dust or grass, insects, etc.):
- Use a high-pressure (HP) steam cleaner with a flat jet nozzle (25°),
- Max. pressure 100 bar,
- Steam: max. 140°C,
- Min. distance between the nozzle and the fins = 200 mm,
- Cleaning fluid: municipal water with pH neutral detergent (pH 7). Avoid alkaline detergents,
- Flushing with clean water using the same adjustment parameters.
The use of detergent is prohibited for cleaning fins with a BLYGOLD ® , ALTENA ® or HERESITE ® coating.
ƒ Prolonged downtime
- To prevent the formation of ice during prolonged downtime, fully drain the coil. Blow all the circuits with compressed air to
bleed them fully. Without this additional pressure, significant amounts of fluid may remain, posing a serious risk of damage
in the event of freezing (not covered by the warranty).
- Recover the water/glycol mixture in accordance with the regulations in force at the installation site.
- If the hydraulic circuit is drained for a period of more than one month, fill the entire circuit with nitrogen to prevent any risk
of corrosion. Observe the maximum operating pressure values indicated in the unit's technical specifications.

Warning!
Follow the safety instructions (see § 2 - SAFETY INSTRUCTIONS).
ƒ Frequency:
- Every three months.
- Every month for ATEX units
- Follow the instructions given in section 10.1 General recommendations for cleaning
ƒ Maintenance:
- In case of problems or if the heaters need to be accessed, they can be removed for complete cleaning or replacement.
ƒ Assembling and disassembling the heater
- Remove the front panel, then the mounting screw to remove the heater.
- For units supplied with a control unit, the electrics box must be disassembled before the heater is disassembled.
