Installing aquastat
To ensure optimum, safe operation,
the supplied stainless steel well must
be installed. The well diameter is
large enough to accommodate a wide
variety of sensing bulbs.
Always use spring-clip to ensure
proper contact of capillary bulb
against the stainless steel well for
proper sensing/heat transfer!
