Application:
Walker Filtration design and manufacture a comprehensive range of
compressed air and gas filtration products for use in almost every
environment. Compressed air line heaters and filter heaters offer
variable temperature control from 20°C to 120°C and are suitable
for industrial or breathing air applications.
Installation:
Filter heaters and air line heaters should be installed as close to the
point of use as possible. Air line heaters must only be used when an
0.01 micron filter housing (XA/AC) is installed directly upstream to
remove particulate contamination. Existing or new pipelines, should
be purged to remove any collected debris.
1. Select position for air line heater or filter heater. It is vital to
depressurise new or existing pipe work before installation.
2. Install air line heater or filter heater onto pipeline observing
vertical orientation and direction of flow arrow marked on the
heater housing. Heaters are provided with Rp or NPT screwed
ports for use with parallel or taper fittings. PTFE tape or thread
sealing compound should be used on pipe threads to ensure a
good connection.
3. The electrical supply to the heaters should be connected in
accordance with Figure 1 (page 11). Ensuring cable is suitably
rated. This product must be earthed. See technical specification.
4. During initial pressurisation of the system, inlet valves should be
opened slowly to reduce inlet velocities until system pressures
are stabilised. Check for leaks before putting heater into
operation.
Operation:
1. Ensure that the rated line voltage and supply voltage are the same:
115V USA and Canada
230V UK and Europe
2. The heater should be protected by appropriate external fusing
(115V-15 amp, 230V-8 amp). It is essential that a switched
fuse spur including a RCD (Residual Current Device) is
used for connecting the heater to the electrical supply.
3. Ensure that the mains connector plug is secured with a fixing
screw prior to operation.
4. Rotate the temperature control knob on the side of the unit fully
anti-clockwise to the 'minimum' setting.
5. Once the compressed air line has been switched on and is
flowing switch on the mains supply to the heater. The maximum
operating pressure is 16 barg (232psig).
6. Turning the control knob clockwise to increase the air
temperature and anti-clockwise to decrease the temperature.
The temperature control knob should be altered gradually to
allow temperature stabilisation to take place. Always decrease
the temperature to the minimum before switching off.
7. If supplied with a thermometer, the air line or filter heater outlet
temperature can be directly monitored.
Caution: The unit you have purchased is capable of heating the
flow of compressed air to 120°C maximum. It is essential that all
pipework associated with the supply of this heated air is capable of
this duty. Maximum temperature tolerance of flexible air hoses vary
significantly, therefore, if in doubt, contact the supplier.
The unit must not be exposed to a conducted electrical disturbance
greater than a frequency of 15MHz. The unit may show evidence of
a temperature decrease.

Maintenance:
There are no serviceable components in the heater assembly or it's
associated control electronics. If a fault or damage occurs to the
unit the following replaceable spare parts are available.
Replacement heating element
Replacement PCB
Replacement sensor
Replacement thermometer
THE HEATER OUTLET PORT AREA AND OUTLET PIPEWORK WILL
BECOME HOT WHEN IN USE – AVOID PERSONAL CONTACT.
ONLY A COMPETENT PERSON SHOULD ATTEMPT TO INSTALL HEATERS
AND CONNECT MAINS SUPPLY WIRING.
SERIOUS PERSONAL INJURY CAN RESULT IF THESE INSTRUCTIONS ARE
NOT FOLLOWED.
DO NOT ATTEMPT TO REMOVE ANY ITEM ON THE HEATER WHILST IT IS
UNDER PRESSURE.
DO NOT OPERATE IF THERE IS A LEAK IN THE HEATER, IMMEDIATELY
TAKE HEATER OUT OF SERVICE AND REMEDY LEAK.
DO NOT OPERATE ABOVE THE MAXIMUM WORKING PRESSURE 16
BARG (232PSIG) AT MAXIMUM OPERATING TEMPERATURE 120°C
VARIABLE OUTLET TEMPERATURE UPTO 120°C (232°F) IS DEPENDANT
UPON THE INLET TEMPERATURE.
