In addition to qualifications outlined above, for personnel, performing some INSTALLATION, SERVICE, REPAIR and DECOMMISSIONING tasks (related to install, repair and/or disposal of mechanical and refrigeration equipment, ductwork, piping, electrical), formal training in respective field and/or trade licensing, issued by local or national authorities may be required.
Delivery and Storage. Receiving Checklist Each piece of equipment is tested and inspected before it ships from the factory; however, the equipment may suffer damage in transit. It is highly recommended to thoroughly check for both visible and concealed damage upon the equipment arrival and before signing the receiving papers: ...
Storage • Protection from the elements is required for any equipment that will be stored on a job site or holding area before installation. • For long-term storage, a controlled indoor environment is highly recommended. • All factory-applied shipping protection should be removed before the equipment is put into storage. Shipping protection material is provided by the factory for shipping only –...

Uncrate/unwrap provided louver and place it over respective opening/damper (Pic. E.3): Larger louvers require two persons to lift and place the louver Dehumidifier with larger louvers also have louver support lip over the damper. Adjust louver position – shift it slightly left or right as needed to ensure louver side walls and access panels do not interfere with damper linkage, actuators, filter racks, sensors, etc.

Outdoor Dehumidifier – Outdoor Air and Exhaust “Door/Louver” Assembly Installation For shipping purposes, the OA and Exhaust Louver(s) may be shipped on the top of the dehumidifier and will require field installation (see Pic. E.5). This normally applies to outdoor NE004-NE008 series dehumidifiers. ...
Outdoor Condenser (OACC) and Fluid Cooler (OAFC) Mechanical Installation The requirements outlined in General Placement of the Equipment (see above) apply to all models of OACC/OAFC. It is recommended to anchor light-weighted OACC/OAFC to the horizontal mounted surface (concrete pad etc.). This applies to all OACC models and some OAFC models (NG-V-01, -02, -11 and -12).
Page 14
OACC model NC-B assembly is shown on Pic. E.7B below: Uncrate/unwrap the condenser and mounting kit. Assemble left and right mount legs as shown with provided bolts, nuts, and washers (except for joint point (a) – it must be bolted to the condenser) Align holes (a) and (b) in the mount legs with the holes in the condenser and attach them with provided bolts, nuts and washers.

NC-Z Pic. E.7C ATTENTION! Cooling Fluid Lines Sweating! Under certain conditions (namely – when the cooling fluid lines’ outer surface drops below dew point of the surrounding air, particularly inside the facility), said lines may “sweat” as condensation forms on their surface. Should this occur, it is recommended to insulate the piping to prevent condensation.
Mechanical Installation – Special Cases Some equipment may have additional/optional arrangements – refer to submittal documentation and equipment accompanying factory instructions. Frame-mounted main blower shipping brackets. For shipping purposes, larger (7 HP and up) direct-driven main blower frame springs are affixed with shipping brackets (see Pic.

“Split-Deck” dehumidifier (“Double-Decker”) – mechanical field disassembly and assembly If requested, “Double-decker” (stacked) dehumidifiers are provided with means for site disassembly (splitting top deck from the bottom for shipping/delivery purposes) and assembly afterwards. Refer to Disassembly and assembly Instructions, provided with the dehumidifier! CAUTION! Before removing top deck from the bottom, ensure that ALL other system connections...
Page 18
“Split-Cut” dehumidifier – mechanical field assembly Under special conditions, the dehumidifier may be split into two or more sections to ease the installation and delivery process. Refer to the dehumidifier submittal drawings and Disassembly and Assembly Instructions, provided with the dehumidifier (instructions include mechanical, piping, and electrical guidance for reassembly). WARNING! DO NOT lift assembled dehumidifier.
Ductwork Connection WARNING! All work must be done by qualified personnel in accordance with local and national Codes, Standards and Regulations as well as respective submittal documentation and manufacturer recommendations. CAUTION! Obtain all necessary documentation (manufacturer documentation, submittal documentation, drawings etc.) and familiarise yourself with it before performing installation or any other related tasks. Refer to dehumidifier submittal drawings for location and size of dehumidifier duct connections.
Maintain the required minimum OA intake along with negative pressure in the space (respective Exhaust Fan and OA intake arrangement) Where/if applicable, establish direct exhaust of humid/chemical laden air from the source (locate exhaust grille above/close to spa, whirlpool, etc.). ...
follow said space heater manufacturer installation instructions (duct transitions, distances, clearances, support, direction, etc.), respective local codes and regulations and standard field practices. Install space heater in the supply duct, downstream of the dehumidifier. It is recommended for the space heater to be controlled by the dehumidifier control system (for efficient operation and air temperature maintenance).
P-trap installation: Make sure that each drain connection has a P-trap Make sure that there is only one P-trap installed (do not double-trap). If soft piping material is used (braided hose, etc.) - ensure the drain line is not sagging (this may create “double-trapping effect”...
Auxilliary pump or main pool pump must be located upstream of (before) the dehumidifier. The dehumidifier normally requires constant waterflow through (to ensure proper automatic control over pool heating feature); however, if requested, it could be equipped with means to control auxiliary pump.

Pressure/Leak Testing. Leak Detection. Refrigeration piping circuit must be leak-free to ensure problem-free operation of the equipment, comply with environmental and safety requirements. Following tasks to ensure that must be performed at different stages of piping. After completion of field piping for split systems, the field pipework shall be PRESSURE TESTED with an inert gas and then vacuum tested prior to refrigerant charging.
Page 26
To determine the field charge, calculate the pipe line set charge by multiplying its length by the charge-per-foot amount show on the main lable, and then add to it OACC charge amount, shown on the main lable as well. Use ball valve access port(s) or additionally installed access port(s) on the line set for charging.
Fluid Cooler Piping (NG models) Line Set Selection and Sizing Refer to dehumidifier and/or fluid cooler main labels for line set typical diameter (both lines, supply and return, • are normally of the same size); note that size may differ from respective piping connections size at the dehumidifier and fluid cooler.
Page 29
Pressure Testing and Charging Refer to the fluid cooler and/or dehumidifier’s main label and • submittal documentation for operating pressure and cooling media selection. Typically, mixture of food grade propylene glycol (with rust inhibitors added) and distilled water is used as a cooling fluid.
Other Piping Systems and Special Cases Space Heating and Space Cooling Hydronic Systems Requirements, outlined in Piping Connection General Considerations (see above), apply to all types of space heating and/or space cooling fluid systems (water, glycol, etc.) – refer to respective piping termination labels (IN/OUT), main label (for line sizing) etc.
