M227/207-CW & M207-CW COOLING UNIT SPECIFICATIONS/INSTALLATION

4. Installation

2. (continued)

NOTE

All cooling systems are subject to problems from mineral buildup, algae

and bacteria. Frequent changes of coolant and flushing of the system are

necessary to keep any cooling system running efficiently. Frequency of

changes is strictly dependent on the environment and quality of coolant

used. Monitor your cooling system carefully and often.

3. Before mounting the

on to the M-207A remove the fill cap

and add the coolant mixture. Replace the fill cap. Remove the pins

attached to each corner post (see figure 8). First time installers should

find the CW Power Cable location and find the location of the mating

connector on the bottom of the M-207A.

4. Move the M-207A onto the CW unit and insert the corners onto the posts

of the CW Unit. Carefully tilt the front of the M-207A up slightly. With

the M-207A still slightly tilted connect the CW Power Cable to the mating

connector on the bottom of the M-207A (it is keyed and can only be

inserted one way). Lower the M-207A slowly (feed any excess cable back

into the CW unit). Secure the CW unit with the pins that were removed

(figure 8).

5. Install the adapter cable coolant hoses per section III. Re-connect the M-

207A power cable.

5. Operation -

1. When all connections have been made per Section III and a coolant flow

path is created, turn the M-207A ON and set the

ON/OFF

switch to ON. The pump should start circulating coolant.

WARNING

DO NOT OPERATE the water cooling unit WITHOUT coolant in the tank

OR WITHOUT a water flow path (water OUT to IN through a weld head).
