Ground-Fault Monitoring and Operation
:
As explained in the “installation planning” section of
this manual, most, if not all, applications using metal-
sheath heaters will require the use of the GF-SK-1
ground-fault sensor switch. Refer to the instructions
provided with this switch for proper installation.
If, during heater operation, the GF-SK-1 “trips” and
interrupts power to your heater or heater circuit, then
one or more of the metal-sheath elements in the
heater or heater circuit being monitored has a reduced
insulation resistance value that may be due to an
element that is about to fail. Have a licensed
electrician follow the warnings and instructions in the
“operation” section of the GF-SK-1 manual.
OPERATION (cont.)
FIRE HAZARD
BURN HAZARD
•
To prevent arcing type
faults, premature element
failure and potential fire
or burn hazard, use
Fostoria model GF-SK-1
ground fault switch with
these heaters.
•
Read and follow all
instructions provided for
proper installation of
heaters and GF-SK-1.
MAINTENANCE
Pre-Season Maintenance and Annual Inspection
To ensure your safety and years of trouble-free operation from the heaters, periodic service and inspections
must be done by a trained maintenance person or licensed electrician.
To obtain maximum performance from your heater(s) each year, we recommend the following be
performed at the start of the heating season:
1. Clean housing reflector surfaces with a damp cloth.
2. Blow or dust off the elements and inner reflectors.
3. Repair or replace damaged power cables.
4. DO NOT hose-down these heaters.
Storage
When storing the heaters for long periods they should be covered to avoid accumulation of dust and other
contaminants. Keep them in dry areas away from dripping or standing water and heavy humidity.
•
Do not store in a damp location.
