A.3 ASSEMBLY INSTRUCTIONS FOR RTU MODELS
A.3.1 SINGLE FAN TOWERS (RTU)
Follow this procedure to assemble and install Single Fan Cooling Towers.
A. Upon the arrival of the equipment to its final destination, check for any abnormality or apparent damage
to the packaging before unloading the Cooling Tower and its components. The packing list must match
with the received merchandise. Any equipment absences or abnormality must be reported directly to
your local REYMSA representative.
B. After verifying the equipment is received in proper condition, proceed to unload it piece by piece, with
a crane or forklift of the appropriate capacity (see Figure A-34 for reference).
C. For unloading a tower from a container, refer to “APPENDIX A: EXAMPLE OF UNLOADING A COOLING
TOWER FROM A CONTAINER”.
D. For crane lifting, it’s recommended to use a minimum lifting angle of 60º between the strap and the
horizontal. The Tower has U-bolts for lifting, one on each corner. Place the straps through the u-bolts (as
shown in Figure A-34) and use a spreader bar to avoid damage on the upper edge of the Tower. Don’t
balance until tensing the straps.
E. Remove the plastic wrap that surrounds the Tower and its components, and loosen the nuts and bolts that
keep the Tower (unitized body & basin) attached to the wooden pallet (those located at the bottom of
basin).
F. Before Tower’s assembly, REYMSA recommends to install a steel base structure that supports the Tower’s
operational weight; also place an isolation pad (supplied by others) between the Tower and the base
structure for support purposes. Verify that the base structure has the proper dimensions (for construction,
refer to factory certified drawings). For more information, see section “A.11.1 LEVELING AND TOWER
SUPPORTS”.
G. Place the Tower (unitized body & basin) section on top of the isolation pad and the steel base structure,
making sure that the anchorage holes on the bottom of the Tower are aligned with the perforations of
the base. Then proceed to bolt it down and secure it with stainless steel nut and bolt sets (supplied by
others) as shown on Figure A-35.
