1 - Installation Failure to heed the following may result in injury or death. WARNING Installation of this equipment by anyone other than a qualified installer can result in a safety hazard. The information contained throughout the "Installation" section is intended for use by qualified installation technicians familiar with the swimming Pool/Spa safety standards.
1.1 Positioning Equipment Failure to heed the following may result in damage to equipment. NOTICE Do not install equipment inside of a building. Outdoor Use Only Do not install equipment inside of a room or building. Heat Pumps require unobstructed airflow for proper operation. Heat Pumps should never be installed indoors or in a location where airflow is restricted.
1.2 Clearances Proper air circulation is required for the heat pump to operate efficiently. The following diagrams show the minimum clearances required for the proper operation of the heat pump. Avoid storing chemical containers near the heat pump. The chemicals can cause equipment damage. Avoid placing objects near or on top of the heat pump.
(Leisure Temp LT1000) 1.4 Plumbing 1.4.a Plumbing Requirements Failure to heed the following may result in damage to equipment. NOTICE Do not use glue on the threaded portion of the equipment’s unions. A glued-in-place union will prevent the equipment from being properly winterized. The heat pump must receive water flow within the specified minimum ranges under worst-case conditions such as a fouled water filter.
1.4.b Plumbing Diagrams Plumbing diagrams are provided in this section as a planning guide to the sequence of equipment, valves, and fittings. The basic plumbing configurations for typical installations are shown. If the installation does not closely follow any of the supplied plumbing diagrams, Leisure Temp Technical Support is available for installation advice and guidance.

1.4.d In-Line Chlorine Feeders Place in-line chlorinators downstream from the heat pump and as low in elevation as possible. If an erosion type feeder is used, it is recommended that a Hartford Loop be installed to protect internal heat pump components. A Hartford Loop is not necessary with a Salt Chlorine Generator.
flow rates. This requires the filter to be cleaned or back-washed. Keep baskets free of debris. A large quantity of debris in the pump and skimmer baskets can reduce water flow. Check for improper valve settings. A partially closed valve after the filter, or a full-open bypass around the heat pump, will cause insufficient water flow through the heat pump.
1.4.f Adjusting Water Flow Using ΔT (Delta-T) The Delta-T is the temperature difference between the water temperatures entering and leaving the heat pump. The equipment can be fine-tuned for maximum performance by balancing water flow rates to maintain an ideal ∆T. The adjustment procedure must be completed with the unit in heating mode.

2.1 Fault Codes A fault code indicates a specific issue or condition that will require action before the equipment can resume operating. Please perform the following troubleshooting. If the issue reoccurs, please contact Leisure Temp. See "Contacts" on page 1. Failure to heed the following will result in injury or death. DANGER Deactivate power while routing wiring to control board.
DEFROST1 SENSOR SHORT DEFROST2 SENSOR SHORT ISSUE Shorted defrost sensor. RESOLUTION A qualified technician should replace the defrost sensor. ERROR AT MASTER UNIT ISSUE The heat pump is slaved to a master heat pump that is displaying a fault code. RESOLUTION The error at the master heat pump must be corrected before the slaved unit will resume operation.
HP5 SYSTEM LOCKOUT ISSUE The heat pump has locked due to five high-pressure faults during one call for heating . RESOLUTION 1. Deactivate then reactivate power to the heat pump to clear error. 2. Troubleshoot the high-pressure issue causing the error. See "HIGH PRESSURE FAULT"...
OTA SYSTEM LOCKOUT ISSUE A malfunction has occurred that could allow the water temperature to surpass a safe level. An installed "Over Temperature Alarm" kit has disabled the system. See "Available Accessories" on page 67 for more information. RESOLUTION Call for service. SMART COMM FAULT ISSUE Heat Pump is not receiving a signal from an external controller using a smart bus connection point.
Blank Display ISSUE The Heat Pump may have an incoming power problem. RESOLUTION Confirm electrical power is being supplied to the heat pump from electrical disconnect(s). Display Panel Not Responding ISSUE The heat pump's display panel will not respond to user input. RESOLUTION 1.
"SET TO SWITCH REMOTELY" Displays ISSUE "SET TO SWITCH If when pressing the "Pool / Spa" button the display flashes the message REMOTELY", the heat pump is using a remote relay switch or a 3-wire controller. RESOLUTION The Pool and Spa thermostat automatically switch when using these modes. Operation manually will not be available when using these external devices.
