2. Water Condenser.
Check the outlet water temperature of
water-cooled condensers at the floor
drain. Water temperature should be
about 95°F (35ºC) with a 70°F (21ºC)
water inlet temperature.
3. Test MTS Slide Switch.
Make sure system is de-
pressurized before pro-
ceeding.
The MTS slide switch feature is designed
to prevent the MTS motor from being
accidentally activated. It is essential that
the proper operation of this switch be
verified on a routine basis. Use the
following instructions to test for proper
operation:
a. Be sure all switches are in the
"OFF" position.
b. Pull down MTS handle to open the
housing.
c. Turn MTS switch to "ON."
DO NOT place hands near
the MTS rollers. Severe
personal injury could result.
