General Safety
The units are designed for "indoor" use only.
The units should be mounted on the floor. if this is impossible
ensure that they are provided with a very stable platform.
Do not position on surface water or where airborne water
(liquid) is present.
Position the unit to allow clear air input and exit from the unit.
A minimum distance of 2 meters should be allowed between
the outlet nozzle of the heater and any obstruction.
Do not use the units when surrounded by combustible
materials.
Maximum surrounding air temperature 40°C
Electrical Safety
The units must be installed in compliance with the appropriate
requirements of the I.E.E. Regulations, 15th Edition.
The units must only operate in conjunction with a permanent
earth connection.
The electrical supply should be appropriately protected by fuse
or circuit breaker as follows:-
Hot Block 25
240 Volt
13 -16 Amps maximum
Hot Block 25
110 Volt
32 Amps maximum
Hot Block 65
415 Volt
20 Amps/phase maximum
Hot Block 95
415 Volt
32 Amps/phase maximum
For use on construction sites refer to CP1017 - Electrical
Distribution on Building Sites.
Trouble Shooting
ALWAYS ISOLATE UNIT FROM ELECTRICITY SUPPLY BEFORE MAINTENANCE
Fault
Likely Problem
Remedial Action
No fan
No electricity supply
Check fuses/breakers.
Check supply cable.
*Meter heater terminal block
for correct supply voltage.
Meter selector switch for
continuity.
Check security of terminals and
cables.
Check fan blade is secure on
motor shaft.
Exchange motor.
No heat
Lack of air
*Meter correct voltage at unit.
Ensure clear access for air
through unit.
Check fan as above.
Check that heat returns after
cool down period.
If unit continues to cycle,
identify faulty overheat
protector and exchange.
Check for continuity through
each heating element and
exchange as appropriate.
*NOTE: A valid check of the correct voltage at the unit can only be carried
out when the unit is operating under full load. This requires the unit to be
run with covers removed. Any fault finding work should be carried out by a
qualified electrical engineer and the unit run with covers off for the
minimum period possible. During maintenance always check that all
components are securely mounted and that all electric terminals are tight.
