Page 26: Batteries/Maintenance
Only a suitably qualified person should replace the batteries of the UPS when this is required. To replace the batteries of the UPS, ensure the EasiHeat unit is turned off and the UPS is not supplying power to the panel. -
Page 27: Functional Test Of Safety Compenents
The EasiHeat is equipped with an electronic circuit protection module, sometimes called a “smart fuse”. This allows programmatic resets of voltage supplies in the event of a tripped fuse. The EasiHeat control software will attempt to reset channels in the event of a trip. -
Page 28: Component Map
The naming convention for the system map do not correlate to the specific parts and part numbers. The tag names are specific to the EasiHeat system and are not tied to specific component models. To identify a particular component, reference the component tag number to the Bill Of Materials for the specific model of Easiheat. -

Numbering of the Areas begins with the inlet flow of the process fluid at Area 0. When the process fluid undergoes a change or state change, the Area number increases until it leaves the Easiheat. The inlet of the control fluid begins with the next available Area number. At each state change of the control fluid, increase the Area number until the control fluid leaves the package. - Page 30 - VEX2 Steam control valve air pressure dump valve. - VEX3 Auxiliary/condensate control valve air pressure dump valve Pump trap motive steam port AREA X Plant steam AREA X AREA 5 Condensate Fig. 9 EasiHeat Schematic Motive steam inlet EasiHeat IM-P565-09 TES Issue 1...
