or implied and of all other obligations or liabilities on our part, and
MAGUIRE PRODUCTS neither assumes nor authorizes any other persons to assume for it any other
liability in connection with the sale of its Dryers.
This warranty shall not apply to equipment repaired or altered outside MAGUIRE PRODUCTS INC.

1.2 – SAFETY WARNINGS
HOT SURFACES:
As with all dryers, there are HOT SURFACES to avoid. Temperatures
can reach 250F (120C), or 350F, (180C) on high temperature models.
All heated surfaces are contained within the external enclosure.
When the door is opened you can access and touch hot surfaces. Typically these
surfaces are not at dangerous temperatures, however all hot surfaces should be
avoided.
Warning Label indicate HOT SURFACES
USE CAUTION when removing and installing canisters.
USE GLOVES.
DO NOT REACH into the dryer enclosure.
INDEXING OF THE MATERIAL CANISTERS:
At the end of each cycle canisters automatically index.
The forces that cause rotation are light. However, the inertia of
already moving canisters might cause injury. Additionally the
disks above and below each canister close automatically and
present a pinch point. For these reasons an interlock on the access door prevents all
operations while the door is open.
DO NOT DEFEAT this interlock.
DO NOT try to index the canisters by hand, against the force of the positioning air
cylinder. They will swing back rapidly when released.
If you disconnect the air supply and then rotate the canisters by hand, reconnecting
the air will cause the canisters to swing rapidly back to their start position.
When connecting the air supply KEEP hands CLEAR. Have the DOOR CLOSED.
DOOR SAFETY INTERLOCK:
There is a safety interlock switch on the door. If you open the door, all operations will
stop. After closing the door, you will need to press START to restart the dryer.
Accumulated cycle time will not be lost.
RISK OF SHOCK:
Disconnect power supply before servicing the Dryer.

2.2.3 – Installing Canisters on Series 200 model Dryers
With 200 Series Dryers, the canisters are packaged separate from the Dryer
itself. To install the Canisters into the Dryer, follow these steps.
Do not damage the edge of the canister. Always rest the
canisters on a rubber mat or thick cardboard and take care
not to damage the edge of the canisters.
After unpacking the canisters, rest the canisters on a rubber
mat to protect the canister edge. Open the Dryer door and
rotate the “Canister Hanger Assembly” around to an empty
station. Grip the two handles of the canister firmly and lift the
canister up into the Dryer, and hang the upper supports into
the “Canister Hanger Assembly”, then swing the lower
supports back to the lower latches.
Hook the canister latch on each side of the canister by pushing the canister
back to the latch, securing the canister.
Note: Each canister hangs in one of three positions in the “Canister Hanger
Assembly”. These three Positions are labeled 1,2 and 3. The number identifies
the canisters position in the assembly.
2.2.4 - Compressed Air Connection
Connect an air supply to the air regulator’s IN port using a male ¼” NPT fitting.
An operating air pressure of 80 psi (5.5 bar) while the vacuum generator
is running is required for proper operation of the Dryer.
Note: The Vacuum Generate runs for the first few minutes of every cycle.
If your air supply has oil in it add an oil separator filter.
Oil in the air will combine with dust drawn from the canisters forming a paste
inside the vacuum generator. It will stop working and require cleaning.
Observe the air pressure gauge to be sure the pressure maintains 80 psi (5.5
bar) while the vacuum generator is running or activate the blow gun releasing
air as you check and adjust the regulator. If pressure drops below 80 psi,
adjust the regulator. If the pressure cannot maintain 80 psi (5.5 bar) while the
vacuum generator is running, then the air supply line is not adequate.
Do not supply Dryer with a lubricated air supply. Damage to
Dryer may result. Use only a clean, dry, oil-free air supply.
