• National Electrical Code, Article 680; Swimming Pools, Fountains, and Similar Installations, shall apply. • National Electrical Code, Article 440, Air-Conditioning and Refrigeration Equipment, shall apply. Connecting External Controllers • See document entitled: “Connecting External Controllers to AquaCal Heat Pumps”; this document is shipped with every AquaCal heater. For extra copies, contact AquaCal Customer Support (800-786-7751); request literature piece: “LTP0050.” • For Call-Flex option, reference instructions received with the Call-Flex kit. • Please contact the AquaCal Technical Support Group (800-786-7751) concerning the application of any external controller, Call-Flex, sequencing control, etc. INSTALLATION Electrical Requirements (continued): Sizing the Electrical Service... Reference the Equipment Data Plate • AquaCal 100, 120, 135, and 155 model heat pumps have two (2) identical data plates affixed: one can be found outside the unit, on right front corner; the second data plate is located behind the front access panel, on the electrical enclosure cover. • Refer to either equipment data plate for unit-specific electrical power supply requirements. • Based on data plate information, size wiring, wiring devices, and over-current protection per applicable codes and standards. • Refer to drawing below for data plate items specific to electrical installation requirements. On the installed heater data plate, the areas depicted below, numbered 1-8, will contain the information required to size the electrical service and over-current protection. ELECTRICAL PORTION of DATA PLATE A Word Concerning Ground-Fault Protection • The National Electrical Code (NEC) contains no standards requiring Ground-Fault Interruption protection (via GFI Circuit Breaker or otherwise) of “Fixed” or “Stationary” equipment, under article 680: Swimming Pools, Fountain, & Similar Installations, or Article 440: Air-Conditioning & Refrigeration Equipment. • The preceding standards govern the installation of AquaCal (and other manufacturers’) heat pumps. AquaCal heat pumps are designed, and safety tested by a certified laboratory, to be installed under applicable standards detailed within the NEC. • AquaCal does not recommend the use of ground fault protective devices in conjunction with heat pumps. Service calls, found to be due to “nuisance” tripping of ground fault devices, are not covered under the AquaCal factory warranty. Controls Configuration & Adjustments Level-2 (Dealer-Service) Microprocessor Programming (Includes Configuration for External Controllers) Level-2 programming involves configuring the controller for specific site characteristics. To explain, this programming is where the controller is set to operate with, or without, an external controller; where sensor calibrations are performed; and where changes to other factory default parameters are made. Before transferring use of the heater to the owner, the installer must insure the controller programming is compatible with any site-installed external controllers, and that the heater starts and operates per the manufacturer’s specifications. Generally speaking, the installer’s main focus within Level-2 programming will be in configuring for external controller compatibility. And, unless instructed to do otherwise by the AquaCal Technical Support Group, the installer should not adjust sensor calibration or dead-band values. CAUTION ! Failure to heed the following may result in equipment damage and voiding of manufacturer’s warranty. Heat pumps contain no owner-serviceable components. Owner-initiated adjustments, beyond the controller “LOC” code, must not be attempted. If adjustments are deemed necessary, the owner should contact installing dealer or AquaCal Customer Support at (800) 786-7751. 1. Entering Service Menu: A. To enter the service menu, Simultaneously press and hold both the [UP ARROW] and [DOWN ARROW] keys until [CF1] (Celsius / Fahrenheit) code appears. (Note: if “000” displays, the User Lock Code is enabled, and the ULC pass code must be entered before proceeding. See Owner-Level Operating Instructions, page-15: “User Lock Code Option [ULC].” If the owner’s ULC pass code is unknown, the factory default code “0” may be used to access controller programming.) Press the [POOL/SPA] key four times to display [LOC], which is the entrance point for the Service Menu. B. The [LOC] code function allows service personnel to use an access code to enter the service menu. This section of the programming is intended for authorized factory service personnel, only. C. Using the [UP] and [DOWN] arrow keys, scroll the displayed number to “50.” (“50” is the default service entry pass code.) D. Once the correct service code is displayed, pressing the [POOL/SPA] key–once again–will allow access to the service menu. E. The first service parameter displayed will be [dEL] (4 -minute time delay on make). NOTE: Pressing the [POOL/SPA] key will save the displayed value in any menu...
