If the product is to sit in storage for a length of time before installation, contact PoolPak Service department for proper storage guidelines.
In its less obvious forms, moisture may penetrate walls and ceilings and cause rot that becomes noticeable only when large scale structural failure occurs. Humidity levels are also a major factor in the comfort of pool users. | MPK Series - Installation, Operation and Maintenance www.poolpak.com | 800-959-7725...
Pool water chemistry is a part of daily maintenance and it is recommended that the users follow the current National Spa Indoor Pool Water and Pool Institute standards. For more information, see the PoolPak Educational Library article ®...
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.
See Figure 2-1 for reference. The CPCS uses dew point control to operate the PoolPak unit and maintain the moisture level below the setpoint. The space dry bulb temperature and relative humidity determine the dew point temperature.
See Figure 2-2 to illustrate the following paragraphs. Refrigerant-Side Operation The PoolPak® 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.

Air Flow Monitoring and Control The best way to control building pressure is by measuring and controlling airflow rates. The PoolPak system employs factory mounted VFD or EC motors on the supply fan array, exhaust fan, and purge fans to modulate airflow. The controller receives feedback from fan inlet measuring stations and the outdoor air measuring station to continuously monitor the outside air, exhaust air, purge air, and supply air flows.
Whenever available, the economizer mode brings in favorable outside air to satisfy the pool room requirements. When economizer is not available, the PoolPak unit performs mechanical dehumidification. The PoolPak provides full proportional control of relative humidity by staging unit capacity. The humidity controller energizes the compressor.
100% outside air is drawn into the PoolPak. All the heat recovered in the PoolPak unit refrigerant is transferred to the supply air in the air reheat condenser.
During times when the pool water requires more heat than is available from the pool water condenser, the PoolPak® activates the auxiliary pool water heater. An auxiliary pool water heater must be supplied as part of the pool water pump and filter system.
Purge Mode (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.

• Remote exhaust fan Selection PoolPak unit selection software is more than an equipment sizing program. It is designed to accurately calculate the entire moisture load for your application. The program incorporates the key design parameters, including ASHRAE ventilation requirement, to help guide the user in meeting the necessary codes. The program also calculates the ventilation load with the outside air airflow requirement that is specified.

If a field-furnished auxiliary space heating coil is installed, the control for this heater must be field wired to the PoolPak control panel as shown in the field wiring diagram (Figure 6-3).
Rigging PoolPak units require the use of spreader bars that are at least as wide as the unit. Care must be taken to prevent damage from the chains or slings used in rigging. In general, two to four lifting points are provided on each side of the unit, depending on the unit size and length.
This power connection feeds the auxiliary electric heating coil. With this option, the contractor is required to supply and install a second fused disconnect. PoolPak MPK units are available in single and dual point power supply options. The 208V option is dual point power only. See illustrations.
The condensate may be piped to a drain or returned to the pool if local codes allow. If returned to the pool, the condensate should be piped to the skimmer. PoolPak LLC recommends neither for, nor against, the practice of returning condensate to the pool.
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® overhangs 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 and the curb.
RIU in the natatorium will not be covered under warranty. The CPCS includes a 7-foot long, black RJ25 cable. If the RIU is to be mounted directly to the PoolPak unit, this cable can be plugged directly into port J10 on control module CM1 in the PoolPak® control panel.
Multi-Unit Network Connection (2) The CPCS utilizes a proprietary, private network to coordinate with other PoolPak units operating in the same space. This allows up to five PoolPak units to coordinate operation using a master/slave scheme. The PoolPak units are connected to each other by daisy-chaining the three terminals of T15.
Wire as shown on the field-wiring diagram. Electrical connection should be made with two-conductor (one shielded, twisted pair), 16-20 AWG copper cable. Connect the shield drain wire to ground at the PoolPak control panel end only. Supply Air Temperature Sensor (5) This sensor measures the air temperature leaving the PoolPak unit to provide indication of possible freeze damage to water coils in the unit.
T12.4-6 provides the analog signal for control of a hot water or steam valve. Normally, this valve is factory-mounted and wired inside the PoolPak unit. However, if a remote valve is used, it can be connected directly to the PoolPak® control panel. Terminal block T12 provides 24 VDC power and a control signal.
The auxiliary heating system is normally factory-installed inside the PoolPak unit. In this case, all interface wiring between the CPCS and the heater is factory-installed. If the PoolPak® is not equipped with an auxiliary heating option, the CPCS provides contact closures to control three discrete stages of auxiliary air heating. The contacts may be directly connected to the heater’s control circuit provided it is 115 VAC maximum and the current does not...
PoolPak® unit. Particular attention must be given to venting when the PoolPak® unit is installed above the level of the main pool water system. When designing a system that has over 20 to 30 feet of vertical rise, the system should be considered to be open (size pump accordingly, assuming no gravitational assistance).
