7. ENVIRONMENT
All materials in contact witch water have been selected to work under severe conditions.
Resistance casing – AISI 316 stain-less steel.
•
Resistance shield – Incoloy 825.
•
These make them suitable for the following conditions:
WATER:
HCLO + CLO:
pH:
CHLORIDES:
ISOCIANURIC ACID:
CaCo :
3
HBrO:
Do not exceed those limits!
8. WARNING
Do not store chlorinated products near the heater, neither in the same room, as they produce highly
corrosive gases.
Do not connect heater if there is a possibility that the water in the circuit is frozen.
There are open outlet water heaters where the outlet works like a ventilator hence, do not connect any
accessories unless they are clearly recommended by the manufacturer.

SOLUTIONS
Check and fix the electric
supply if necessary.
Replace or fix the thermostat,
then restart the heater.
If after resetting, the problem
persists, or it is not possible to
reset, this indicates that switch
has been damaged, therefore it
must be replaced.
Backwash the filter to restore
flow.
Fix unusual air entry.
Check and replace if necessary.
Check resistance between two
poles of resistance fork
48Ω for 3Kw
25Ω for 6Kw
16Ω for 9Kw
12Ω for 12Kw
8Ω for 18Kw
Replace resistances if thy do
not reach those values.
Check flow switch operation.
Check for continuity with paddle
pushed. Replace if necessary.
