3. Installation
3.1. Pre-Installation Requirements
Please note the following items related to this unit and its installation must be completed prior to scheduling the
factory technician for startup.
All wiring (Power and Control), electrical components, control devices, and electrical service should
be completed in accordance with
NFPA 70, NEC
(National Fire Protection Association, National
Electrical Code). Wiring and components must also comply with all State and Local Code
requirements along with installation plans and unit specifications.
All venting, cooling, refrigeration, plumbing and piping should be installed per
UMC, ASHRAE
(Uniform Mechanical Code, American Society Heating, Refrigeration and Air Conditioning Engineers)
requirements for building and energy efficiency. All components must also comply with all State and
Local Code requirements along with installation plans and unit specifications.
All air supply, ducting and connections must be completed per
UMC, AMCA, and SMACNA
(Uniform Mechanical Code, Air Movement and Control Association - International Inc, Sheet Metal
and Air Conditioning Contractors National Association) specifications. All components must also
comply with all State and Local Code requirements along with installation plans and specifications.
3.2. Pre Checks and Inspection before Installation
The unit must be lifted carefully with assistance as necessary. Personnel must be capable of lifting weight
shown on dimensional drawing or Specifications Section 1.3. See
Appendix
for additional unit dimensions and
weight. If a lift is used, please use spreader bars that are two - four inches wider than the unit width to prevent
from squeezing the top of the unit. Failure to do so may damage the unit.
For proper mounting, review all drawings; dimensions, ducting, submittal package, notes on orientation and
positioning and confirm this information before installing unit(s).
Noise control issues
should be taken into consideration when installing unit. Modern roof and construction is
normally lightweight. Where the DryCool unit is located over noise sensitive areas, noise may be a concern.
Generally, the distance between the roof-mounted equipment and the closest occupied spaces below the roof is
insufficient to apply standard sound control treatments.
A summary of sound level measurements are shown in the appendix. This information should be used as a
reference point for noise control considerations prior to placing unit. Simple Slow Time Weighing and Slow
Time Weighing Sound Level Equivalent charts for the Drycool HD™ can be viewed in the
Appendix
. Unit
sound level measurements were taken with system operating in the Airlab at Munters/Amesbury. Background
sound measurements were taken before and after testing and represent the ambient noise levels at the time the
system was sound level tested.
Upon unit arrival, inspect immediately for signs of shipping damage. If you do notice any damage, report it to
the shipping company and to Munters immediately.
1.
Check all items in the shipment carefully against the bill of lading. Be sure all of the listed items have been
received and none are missing.
2.
Remove packing materials from unit to check the following items:
Unit is in position and evenly supported.
Unit is level.
Outside air is filtered before entering the building.
3.
Check the electrical panels and controls:
Check for any signs of damage.
Check the tightness of all electrical connections. Carefully check the power wiring terminals.
