Installation

Read through instructions thoroughly before installation. Installation instructions are intended for use by a qualified technician, specifically trained and experienced in the installation of this type of equipment. Some states or provinces require that the installer be licensed. If this is the case in the state or province where the heater is located, the contractor must be properly certified. Sprinkler Heads: Be sure that there are no sprinkler heads near the heater that will spray on or into the unit. Many sprinkler systems are connected to a well system whose water is high in minerals, sulfur, salt, and other aggressive contaminants that can cause corrosion and shorten life.

The Use Of A Pool Cover Is Recommended. A pool cover reduces heat loss, conserves chemicals, lowers the load on filter systems, and may provide a valuable safety feature. Materials Needed For Installation
The following plumbing items are needed.2-inch Isolation Valves qty (3)

• 2-inch Check Valve qty (1)
• 2 x 2 x 2 PVC Tees qty (2)

For proper installation, appropriate electrical supplies will be needed along with extra hardware items that may be required for anchoring.

Locating The Heater

The installation location of the heat pump is very important for its efficient operation. The heat pump will perform more efficiently when placed in direct sunlight with ample air intake and the avoidance of air recirculation. Locate the pool heater in an area where its condensation will not result in damage to the area adjacent to the heater or a nearby structure.

Outdoor Installation And Service Clearances

The heater must be installed outdoors such that the installation and service clearances shown in Table 3 and Figure 6 are maintained. Additional installation requirements are as listed:

1. Suitable electrical supply line. See the rating plate on the heat pump units for electrical specifications. A junction box is not needed at the heat pump; connections are made inside the heat pump’s electrical compartment. Minimum wire size to be selected per NEC based on unit MCA.
2. An electric disconnect switch that will interrupt all power to the unit. This switch MUST be within line of sight of the heat pump.
3.  Do not install in a location where growing shrubs may, in time, obstruct a heater’s air flow areas (sides or top).
4. Do not install this appliance under an overhang less than 72in from the top of the appliance. The area under the overhang must be open on (3) sides.
5. Do not install the heater where water spray from ground level can contact the heater. The water could damage the coil or reach the controls, causing electrical damage.
6. Do not install under a deck.
7. Do not install within 12″ of any outdoor HVAC equipment.
8. Do not install where water may run off a roof into the heater. A gutter may be needed to protect the heater.

Outdoor Minimum Clearances

Equipment Pad: Place the heat pump on a level surface such as concrete or a fabricated slab (pad). This allows proper drainage of condensation and rainwater from the base of the unit. If possible, the pad should be placed at the same level or slightly higher than the filter system equipment pad.

Flooring: This heater may be installed on either non-combustible flooring or combustible flooring that does not reduce the bottom clearance of the heater. Ultralite™ or equivalent concrete-over-foam HVAC pads are acceptable.

Drainage and Condensation: Condensation will be produced by the evaporator coil when the unit is running and draining at a steady rate, usually three to five gallons per hour, depending upon ambient air temperature and humidity. The more humid the conditions, the more condensation will be produced.

Anchoring: The heater is equipped for the installation of anchoring screws when required by local codes. Follow all relevant Local, State, and National requirements regarding wind load anchoring. When anchoring is required to secure the heat pump to a concrete pad, use the specified hardware shown in Figure 7. To complete the installation, use the following:

• Anchor Clamps (Included)
• Concrete tapping screws (Not Included)
• Fender washers (Not Included)
• qty (8), spaced at least 2½” apart
• qty (8), Tapcons® stainless steel, size to be ¼” diameter with a minimum length of 1½”
• qty (8), stainless steel, size to be 1½”

Equipment Pad and Anchoring

Water Piping

General: The heater is for use with pool and spa/hot tub water furnished by municipal water distribution systems only. Do not use the heater for mineral water, seawater (PPM>5000), or other non-potable waters. These heat pumps are designed for nominal water flows through the condenser. A minimum flow of 30 gpm is required to ensure sufficient heat removal from the condenser, thus avoiding overheating the unit. The minimum flow rate is to be calculated or measured with the in-floor cleaning system in use, if the pool is so equipped, as well as any other jets or other demands on the water flow.

Flow rates above 75 gpm will create excessive pressure drop through the condenser and require unnecessarily high pumping energy. Bypass valve setting may be accomplished by temporarily installing a flow meter on the outlet line of the heater.

Then adjust the manual bypass valve until the flow rate through the heater is within the flow rate range specified. Once the manual bypass valve is set, note the position and remove the valve handle to prevent accidental adjustment. Failure to install an External Bypass Assembly with a flow rate of 75 GPM can cause damage. Do not install any restriction in the water pipe between the heater outlet and the po,ol except for: a three-way switching valve, an in-line chlorinator, and/or a chlorinator.

General Pad Plumbing Layout

• Improperly adjusted manual bypass valves will result in damage to the heater if the flow rates are not maintained under all operating conditions as specified in the listed SPECIFICATION.
• The heat pump must be protected from back siphoning of water. If there is any chance of back siphoning, provide a check valve between the pool and the filter pump inlet. Failure to follow the instructions may result in property damage due to flooding.

Typical Pool Arrangement

Also shown is the implementation of an optional gas or solar heater system for additional capacity. Other pool heaters, such as gas or solar-powered devices, can only be installed in a parallel circuit and operated independently (only one at a time) for your warranty to be valid.Multiple Heater System

1. Maintain 12″ [31 cm] clearance between the units, 12 in. [31 cm] around the perimeter, and at least 6 ft [1,8 m] over them. Refer to the Locating the Heater section for more details.
2. Install bypass loops for each unit.
3. Install union style fittings from the heat pump CONSUMER KIT adjacent to the unit to facilitate easy service p.. procedures

Automatic Chlorinators and Chemical Feeders

Install a separate positive seal corrosion-resistant check valve between the heater outlet and the chlorinator to prevent highly concentrated sanitizer from back siphoning into the heater.

Electrical Wiring

The heater must also have independent ground and bond connections. There is a ground lug inside the control box adjacent to the power connections and a bonding lug on the side of the heater. Use a solid copper conductor, size 8 or larger. Run a continuous wire from the external bonding lug to the reinforcing rod or mesh. Connect a No. 8 AWG (8.4 mm2 ) solid copper bonding wire to the grounding lug provided on the heat pump and to all metal parts of the swimming pool or spa, and to all electrical equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of the swimming pool or spa. IMPORTANT – Reference NEC codes for all wiring standards, including, but not limited to, grounding, bonding, and other general wiring procedures.

Electrical Connections

Turn off the source power to the heat pump before working on electrical connections. Plug any unused openings with the supplied caps.

Remote Control Connection

The heater is equipped for remote control via independent 2-wire connections. Heat-only models connect the remote relay to terminal J7. Heat/Cool models connect the heating remote relay to terminal J7 and the cooling remote relay to terminal J28. (See Figure 14 for remote on/off connections).

1. Connect the Heating remote relay to the J7 connection and the Cooling remote relay to the J28 connection L(if applicable) on the control board.
2. Turn the unit on. Press and hold both the “MENU” and the “+” buttons until “bo” appears. This enables the bypass operation.
