Note:
1. After a component is replaced or the inspection is completed, turn the breaker OFF for
a period of 3 minutes before restarting to confirm the error does not re-occur.
2. If the corrective actions above do not solve the error problem, a malfunction of the PCB
is highly likely.
Water Supply Quality (Supplemental)
Chloride and PH
In areas with a high concentration of chloride in the water, that water can cause
corrosion and subsequent failures. Where the chloride level exceeds 0.1 ounces per
gallons (200 mg/litre), the warranty is no longer valid on to the heat pump unit and tank
unit.
PH is a measure of whether the water is alkaline or acid. In an acidic water supply, the
water can attack the parts and cause them to fail.
No warranty coverage is given on the heat pump unit and tank unit where the PH is
less than 6.0.
Supply Water with a PH less than 6.0 may be treated to raise the PH.
It is recommended that an analysis of the Supply Water be conducted before
connecting the Heat pump unit to the system.
