Pre-Installation Inspection
•
Each heater (and heater with in-line thermostat) is manufactured to the highest
standard with great care and quality materials. All the goods are thoroughly
inspected and tested before leaving the manufacturing plant, and they must be
handled with care during storage and installation. Before the installation starts it is
advised that the heater is checked to ensure the insulation resistance reading is
above 2MΩ per element at
no less than 500 volts dc.
•
Should the Anti-Condensation heater fail this test contact the technical help on our
website: www.exheat-industrial.com/contact/support
•
Inspect the heater for visible signs of damage, paying particular attention to the
supply cable, as this may get damaged during transport, also ensure that the heater
is not bent or squashed and that the fixing holes are free from obstruction.
Compliance with these instructions is a warranty requirement. Documented evidence must
be maintained in the form of a signed checklist. Copies of completed checklists and records
will be required in the event of any warranty claim.
Insulation Resistance
•
The Insulation Resistance Test should be applied between the phase(s) and earth. A
reading of greater than 2MΩ at
no less than 500 volts dc should be recorded.
•
If the HEF heater has an in-line thermostat connected, the thermostat must be closed
for this test to be undertaken.
