Frost Areas
The Hiline fitted with NPT collectors is not suitable for installation in frost areas. A Premier
Hiline must be installed if frost is likely to occur.
Operating Thermostat
The Robertshaw EWT1L2-552 thermostat (part number 051333) was replaced by the
Robertshaw ST1203133 thermostat (part number 052012) in August 2007.
It should be noted that although the ST series thermostat is a direct replacement for the
EWT series thermostat, the terminal connections and wiring arrangement is different.
Therefore;
Whenever an EWT series thermostat is replaced with a ST series thermostat,
rewiring at the thermostat will be required. Refer to wiring diagrams in
technical bulletin TB07 016 for wiring arrangements utilising the new ST
series thermostat.
