compact blower
•
To change the position, remove the three cap-head crews that secure the pulley to the hub and remove the pulley.
Mark the position of the hub to ensure this is replaced in the same position.
•
Release the hub by undoing the two cap-head screws and the one grub-screw that locks the key in position.
•
The hub can now be positioned along the shaft to the new dimension. You may need to tap it with a soft faced mallet.
•
Re-tighten the grub-screw and cap-head screws. Re-mount and secure the pulley.
•
After fitting the head, the pulley alignment can be checked by using a long straight edge.
•
All nuts to be new ‘Nyloc’ or loctite to be applied.
To remove the blower head
•
Isolate the power supply.
•
Remove the belt guard.
•
Disconnect any ducting.
•
Loosen the 4 off M10 bolts clamping the motor mounting plate to the blower back plate, using a 17mm spanner or
socket.
•
Slacken the 2 off M12 nuts on adjustment screw above and below adjustment anchor cast into motor mounting
plate, slacken top nut using a 19mm spanner, to allow the blower head/back plate assembly to drop sufficiently to
facilitate the removal of the belt.
•
After removal ensure the pulleys are clear of any dust or debris. If the belt is to be re-used wipe with a dry cloth before
attempting to refit.
•
Once the belt is removed the four M10 clamping bolts can be fully withdrawn from the motor mounting plate. This
will allow the head to become detached.
•
Remove the M12 belt tensioning stud from the used head with a 19mm spanner.
Refitting a new head
•
Fit the belt tensioning stud from the old head to the new head assembly
•
Lift the blower head into position onto the motor mounting plate & refit the four M10 clamping bolts through the
motor mounting plate.
•
Fit the new belt over the pulleys ensuring that it is correctly aligned with the poly-vee pulleys. Do not force the belt or
roll the belt onto the pulleys. Ensure the blower head is low enough to allow the belt to clear before attempting to fit.
•
Using the M12 nuts on the adjusting screw, apply sufficient tension to raise the blower head/back plate assembly into
its approximate position and lightly tighten the M10 bolts to hold the assembly in place.
•
Tension using the M12 nut on the upper side of the adjustment anchor checking the tension with ‘Krikit’ tension
gauge supplied. (Refer to figures 4 & 5). When the correct tension is achieved (50kg or110lbs on the scale), lock
adjuster by tightening the M12 nut on the underside of the adjustment anchor and tighten M10 bolts to approx.
20N/M.
•
Refit the belt guard.
•
Reconnect the blower ducting.
•
The electrical supply should now be reconnected.
•
After fitting a new belt, the tension should be re-checked after the unit has been run between 10-20 minutes.
•
This is due to initial stretch of a new belt.
•
Only drive belts supplied by Almeco should be used.
Fitting an EP-250/T/SN (or EP-250HT) replacement head assembly on the EP10 in place of a nonthermal cut-out head.
•
On receipt of the blower head you will have additional thermal cut-out’s as well as a control wire lead set. The thermal
cut-out head should be fitted as per the standard head, please see section 3c for full details.
•
To electrically fit the thermal cut-out devices it is necessary to break into the motor thermistor circuit inside the motor
terminal box. Please follow the diagram shown overleaf.
•
If an Almeco Soft Start or Star/Delta Starter is used, upon a trip from either the motor thermistor or the thermal cut-
out probes the blower will stop. Only upon turning the starter off and then on again (once the thermal cut-out has
cooled) can running of the blower then resume.
•
If a non Almeco supplied starter is used it is vital that the blower will not restart automatically after the thermistor or
cut-out probe has cooled. In this case this is the customer’s responsibility.
•
Please note that the motor thermistor must be used in order for Almeco to uphold its warranty.
