Page 7: Piping
PIPING All piping connections are 5/8" OD copper tubing (see Fig.4). The supply and return piping must be adequately sized to meet the design water flow requirements as specified for the specific installation. All chilled water piping must be insulated to prevent condensation. It is also recommended that all piping be insulated to prevent freezing when piping is run in an uncondi- tioned space. -
Page 8: Drain Piping
Drain Piping Condensate drain lines must be installed with adequate slope away from the unit to assure positive drainage. Since the drain pan is located on the suction side of the blower, a negative pressure exists at the drain pan and a minimum trap of 1-1/2"... -
Page 9: Sequence Of Operation
YCW With a Chilled Water Coil The unit will respond to a cooling command from the thermostat by powering a water control valve open. The fan will operate at the speed selected at the thermostat. When the space reaches the temperature setpoint at the thermostat, the cooling valve will close and the fan will continue to operate. - Page 10 MOTOR The blower motor should be cleaned annually and if it has oiling ports, it should be oiled with a good grade of SAE 20 oil. Normally a few drops of oil in each bearing is sufficient. COIL The coil must be kept clean by any of the following methods.
