RIGGING AND POSITIONING
Rigging procedures vary depending on whether the chiller
is shipped in one or 2 pieces.
Lifting the chiller from points other than those specified
may result in serious damage and personal injury. Rig-
ging equipment and procedures must be adequate for
chiller weights and sizes. Refer to Tables 1 and 2 for
chiller weights, and Fig. 3 and 4 for overall dimensions.
Rig One-Piece Units (Fig. 5) —
Lift the entire as-
sembly with cable slings placed under the lower shell, as
shown in Fig. 5, to distribute and balance the weight.
Rig Two-Piece Units (Fig. 6)
If the chiller is assembled before it is rigged, to avoid
damage to the chiller, do not lift under the generator
shell or waterboxes. The chiller should be lifted under
the absorber-evaporator shell.
PREPARATION — Two-piece units must be prepared for
installation before they can be rigged. Refer to Fig. 7-10.
1. Open the auxiliary evacuation valves to relieve pressure
in the absorber-evaporator shell.
2. Open the shipping valve on the generator-condenser as-
sembly to relieve pressure.
To keep foreign particles out of the chiller, do not leave
chiller open any longer than necessary.
Do not remove any stock from pipe ends. Do not get
slag inside chiller while flamecutting.
3. Remove all piping end plates by flamecutting the end plate,
and weld the flange around each outer diameter as shown
in Fig. 7. Cut these pieces, as shown in Fig. 8, for proper
reconnection.
4. Grind the cut pieces smooth for a close fit when the chiller
pieces are assembled.
