Reassembly
1 . Starting with the coil/access section, attach the double
galvanized steel plates to the base .
2 . Line up the compressor/condenser section with the coil/
access section . Slide the compressor/condenser section
towards the coil section . Attach the two sections using
the double galvanized steel plates . Install painted steel
plates (flat) in their respective areas.
3 . Braze the refrigerant (liquid and suction) lines between
two sections (Note: R410A design working pressure is
450 PSI . or as indicated on the unit data label) . Similar
factory joints are brazed with Copper-Phosphoros-2%
Silver brazing rods .
4 . Connect water pipes using the Victaulic couplings . Test
water pipes for leaks in areas with new connections . Test
refrigerant pipes for leaks in new brazed areas .
5 . Evacuate, test and charge the refrigerant circuits with
R410A . See dataplate for refrigerant charge amount per
circuit .
6 . Lift the supply fan section taking care to align the splice
joint to seat into the mating gasket of the coil/access
section to provide an air tight seal . All corners of the unit
sections must line up before some of the flat and right
angle steel plates can be installed to stabilize the fan,
coil and compressor/condenser sections together .
7 . All units have shipping brackets holding the fan tight
in place during shipping . Remove brackets before
commissioning the fan section and adjust the spring
isolators before installing the control panel box .
8 . Organize all wire harnesses in each section and get
them ready to reconnect to the Control Panel .
9 . Lift the Control Panel into place . Attach the section using
painted flat and right angle steel plates (
Figure 5
) . After
the control box is secure, re-connect power wires, control
plugs and sensors .
CAUTION
Keep your hands at a safe distance from the unit while guiding
the wires into the control panel during installation . Make sure
no wire get caught under the Control panel box frame .
WARNING
Re-install interconnecting wires only, after the panel has been
set and secured .
