INSTALLATION

Plumbing Requirements

Overview

When planning plumbing system layout, reference the plumbing schematics within this section as a guide to the sequence of equipment, valves, fittings, etc. The plumbing configurations for typical instal- lations are diagrammed. In operation, it is imperative the heat pump receive water flow within the minimum-maximum ranges specified for the particular heat pump. Should the system installation under consideration not closely match any of the schematics, contact AquaCal Technical Support Group for advice and guidance: (800) 786-7751.

Parts and Materials

Industry technology changes much too rapidly for AquaCal to specify, with exactness, any items out- side and beyond the heat pump. What is specified is that the heater must be installed in accordance with all applicable local, state, or national codes & standards.

In-Line Chlorine Feeders

The titanium heat exchanger tube is nearly impervious to chemical damage; however, other parts of the heater may be damaged by concentrated chlorine. Caution: Per chlorinator manufacturers’ rec- ommendations, always place in-line chlorinators as low, and as far downstream from the heater as possible.

Maintain Ability to Winterize

In regions where hard freeze conditions are typical, the unions mentioned below allow for easy discon- nection and re-connection of the heater from/to the plumbing system. Caution: Do not defeat the function of the unions–use no glue on the threaded portion of the unions.

Water Connections to Heat Pump

All AquaCal heat pumps are supplied with 2" PVC plumbing unions. Connection to site plumbing is made via PVC solvent cement to the female slip socket of the plumbing unions.

Maximum Operating Pressure: 50-PSI

Minimum - Maximum Water Flow Rates

•All AquaCal 100, 120, and 155 models are designed to operate successfully at flow rates of 20- to-70 gallons-per-minute (GPM).

•Design the plumbing system to maintain at least 20-GPM flow through the heater; the heat pump will not operate correctly, nor reliably, with less than 20-GPM of water flow supplied.

•If water flow rates through the heater will exceed 70-GPM, a spring-check bypass valve will be required. Please contact AquaCal Engineering Group to obtain the valve specification specific to your installation (800-786-7751).

•Generally speaking, most residential pools and spas will not require a plumbing bypass unless a pump of two (2) horsepower, or larger, is used. For bypass valve placement details, see plumbing schematic contained on next page: “…Flow Greater than 70-GPM.”

CAUTION !

Failure to heed the following may result in damage to

equipment.

 

 

Use of an incorrect bypass valve may compromise the heat pump’s efficiency, reliability, and may void the factory warranty. Please contact AquaCal Engineering Group to obtain the valve specification specific to your installation (800-786-7751).

120, 155 specifications

Aquacal 155,120 is a highly regarded pool heater known for its efficiency, reliability, and advanced technology. This product stands out in the competitive market of swimming pool heating solutions, making it a popular choice among pool owners and professionals alike.

One of the main features of the Aquacal 155,120 is its high-performance heat exchanger, made from durable titanium. This material ensures resistance to corrosion and enhances the longevity of the heater. The titanium heat exchanger is designed to facilitate maximum heat transfer, providing rapid warming of pool water and ensuring a consistent swimming experience.

The units are equipped with a powerful compressor that utilizes advanced inverter technology. This technology enables the heater to adjust its output according to the pool’s needs, optimizing energy consumption and reducing operational costs. The inverter-driven compressor allows the Aquacal 155,120 to operate quietly, making it ideal for residential settings where noise could be a concern.

Aquacal has designed the unit to be user-friendly, featuring an intuitive digital control panel. This control panel allows users to easily monitor and adjust the temperature settings, ensuring that the water temperature can be maintained at a comfortable level. Additionally, this feature includes programmable settings to enable automatic heating schedules, providing convenience and energy savings for pool owners.

The Aquacal 155,120 is also known for its energy efficiency. With a high coefficient of performance (COP), this heater can deliver more heat output per unit of energy consumed compared to traditional heating systems. This efficiency contributes to a lower carbon footprint, making it an environmentally friendly choice for heating pool water.

Furthermore, the unit is designed with robust insulation, which minimizes heat loss and maximizes energy retention. This insulation helps maintain the desired water temperature for longer periods, reducing the need for frequent reheating and thereby lowering energy expenses.

In summary, the Aquacal 155,120 is an outstanding choice for pool owners looking for an efficient, reliable, and technologically advanced heating solution. With its titanium heat exchanger, inverter technology, user-friendly control panel, energy efficiency, and excellent insulation, this pool heater stands out as a top contender for modern pool heating needs. Whether for leisure activities or extended swimming seasons, the Aquacal 155,120 ensures a comfortable and enjoyable swimming experience.
