Page 7: Section I: Indoor Pool Application
The PoolPak™ System utilizes an environmental control package designed to meet all special needs of the indoor pool environment, while reducing energy usage and building maintenance costs. -
Page 8: Occupant Comfort
A strong “chlorine” odor is an indicator of poor pool water chemistry and is generally offensive to the occupants. Higher levels of chloramines can cause skin/eye irritation and respiratory problems commonly known as “lifeguard lung”. Most poolrooms are designed with a minimum ventilation rate to dilute the airborne pollutants generated from the chemical interactions in the pool water. -

ROOM AIR DISTRIBUTION All PoolPak™ models provide continuous air recirculation, and with a good air distribution system, will promote uniform space conditions. To remove the required moisture and maintain controlled conditions, it is essential that there be adequate air movement and distribution in the natatorium. -

Supply ducts should be as short and with as few turns as possible. -
Page 12: Return Air
PoolPak™ System. Return grilles can be placed high in the space to reduce return ductwork, however removal of chloramines from the occupied area has become much more of a design consideration and so low returns are favored by poolroom designers. -
Page 13: Air Connections To Poolpak
Ducts can be fabric, aluminum, PVC, or galvanized steel. Even though “dry air” is being supplied back to the pool, do not use duct board or similar materials. If the PoolPak™ unit is installed in an area that is below the natatorium’s dew point temperature, the ducts may require insulation, pitching and drainage. -
Page 14: Section Ii: Poolpak Principles, Functions, And Features
System’s major function is to dehumidify the pool enclosure air through a vapor compression cycle. During this cycle the PoolPak™ System recycles the sensible and latent heat and places it back into the pool water and air as needed. This recycling process saves money and keeps your pool environment efficient and safe. -
Page 15: Room Dew Point Control
“grains of moisture per pound of dry air” and is directly related to the dew point temperature. The ECC uses dew point control to operate the PoolPak™ unit and maintain the moisture level below the setpoint (see Figure 2-1). The space dry bulb temperature and relative humidity determine the dew point temperature. By varying the space temperature and space relative humidity set points, the dew point set point is changed. -
Page 16: Poolpak™ Operation
POOLPAK™ OPERATION The PoolPak™ fan draws in warm, moist air from the pool enclosure. This air passes through the evaporator (dehumidification) coil and gives up heat energy to the refrigerant which is in a cool, liquid state. This exchange of energy causes the air temperature to fall below its dew point, resulting in moisture condensation on the evaporator coil. -

PURGE MODE (SR AND SEP) The PoolPak™ has a purge cycle to fully ventilate the natatorium at the airflow (CFM) specified for the unit’s supply fan. The purge cycle is programmable by the owner as necessary to ventilate the natatorium after shocking the pool. Unit controls provide completely automatic operation by controlling the supply fan and return (or purge) fan and by opening the outside air and exhaust air dampers for the programmed time intervals. -

Page 35: Section Iv: Installation
RIGGING PoolPak™ units require the use of a spreader bar that is at least as wide as the unit. Care must be taken to remove all doors or openings that will interfere with the chains or slings to prevent damage to the unit. In general, two to four lifting points are provided on each side of the unit, depending on the unit size and length. -
Page 36: Foundation
The unit must be mounted on a flat and level foundation capable of supporting the entire operating weight of the equipment. The unit MUST NOT set flat on a concrete slab. The PoolPak™ unit MUST BE raised 6 inches to allow for sufficient height to adequately trap the condensate line and to allow for electrical service entrance. -

Curbs have been designed specifically for the PoolPak™ product line. Contact factory for roof curb dimensions. The outside dimensions of the curb are such that the base of the PoolPak™ extends over the edge of the curb on each side. This aids in preventing rain water, running down the sides of the unit, from getting between the base of the PoolPak™... -

PoolPak™ System. It is only turned on either when the heat available from the PoolPak™ is insufficient for pool water heating and pool water temperature drops to 1.5°F below set point or when the pool water flow to the PoolPak™ unit is below the minimum required water flow. -
Page 45: Pool Water Flow Switch
A pool water loop flow switch is factory-installed in the PoolPak™ unit. The flow switch is factory-calibrated and should not be adjusted. If the flow switch contacts are not closed when water is flowing through the PoolPak™ unit, there may be insufficient water flow. -
Page 46: Condensate Drains And Piping
If condensate is returned to a closed filter system that does not have a surge tank, care must be taken to ensure free flow of condensate back to the closed filter. For additional questions or concerns regarding installation of condensate drains, please contact PoolPak™ Service. Figure 4-3. Negative Pressure Condensate Piping Schematic... -
Page 47: Air-Cooled Condenser Installation
AIR-COOLED CONDENSER INSTALLATION SPACE AND LOCATION REQUIREMENTS The most important consideration which must be taken into account when deciding upon the locations of air-cooled equipment is the provision for a supply of ambient air to the condenser, and removal of heated air from the condenser area. -
Page 48: Units In Pits
Units in Pits The top of the unit should be level with the top of the pit and side distances increased to “2W”. If the top of the units is not level with the top of the pit, discharge cones or stacks must be used to raise discharge air to the top of the pit. This is a minimum requirement. -
Page 49: Field Installed Piping
◦ The highest point in the discharge line should be above the highest point in the condenser coil. (See Figure 4-8) ◦ The hot gas line should loop toward the floor if the condenser is located above the PoolPak™ unit, especially if the hot gas riser is long. -
Page 50: Table 4-1. Pipe Sizes For Remote Refrigerant Condensers
Above chart is for lineset length less than 100 ft and ACC located less than 50ft above unit or 20ft below unit. Failures due to a piping layout not within these limits nor receiving prior PoolPak Factory approval will not be covered under PoolPak™ warranty. -
