SECTION 5 – LEVELING THE UNIT
The YORK ParaFlow
TM
Chiller/Heater will operate
prop er ly and produce maximum output only if it is
installed level. Therefore, it is important that the unit
be leveled when installed in place, and checked again
(and adjusted if necessary) after the piping, solution,
refrigerant and system water have been installed.
G-style units are provided with punch-marked lev el-
ing lines and an indicating sticker at each level line on
the tube sheets. See photo in Figure 4 on page 21.
Use these lines as ref er ence points when lev el ing the
unit. Do not use the bot tom of the tube sheet or any
part of the indicating sticker.
