LOCATION OF HEAT PUMP
Location is probably the most important consideration when installing a heat pump. Poor installation can adversely affect performance, as well as cause problems with servicing and overall customer satisfaction.
PREFERRED LOCATION PLACEMENT
Have as much space as possible between the heater and house or any overhangs. Example shown is a preferred installation but is not always practical.
EXAMPLE OF A NORMAL INSTALL
See an example of a standard installation, which should work correctly with the space available.
Make sure there are no overhangs that would cause the unit to recirculate the cold air.
This will make the unit go into defrost mode.
COLD AIR RECIRCULATION
The heat pump gets its heat from the surrounding air; therefore, recirculation of the cold air off the top of the unit should be avoided. Enclosed spaces such as garages and sheds without proper ventilation should be avoided and may void warranty of the refrigerant components. In order to maintain maximum performance, avoid low overhangs such as porches, overhanging brush, etc., whenever possible.

DOs & DON’Ts OF PLUMBING THE UNIT
Consider the direction the heater is facing. The water connections run out the side of the heater. This keeps piping out of the way so customers and service personnel don’t step on or trip over the piping. It defeats the purpose to run the piping back around the front of the heater. Try to keep all piping out of the way.
Do plumb unit to side.
Don’t run pipes back around to the front of the unit. This makes access to the panel difficult for service.

Don’t plumb unit so that service personnel cannot remove or easily access the corner panel.

A simple 90° turn can make all the difference for easy access between
serviceable and non-serviceable.

THE CONTROL PANEL MUST ALWAYS FACE OUT, away from walls and obstructions
for ease of customer use and serviceability.

PLUMBING SEQUENCE
It is very important to plumb in the correct order.
PLUMBING SEQUENCE
The piping sequence is Pool Pump Filter Heater Chlorination System(s) Pool. Rigid PVC piping is recommended and all joints secured with PVC glue. Installation MUST conform to all local codes. Make sure water-flow is correct as indicated on the back of the heater. Again, try to keep piping away from areas that may be tripped over or stepped on when operating heater or servicing. Try to keep elbows and piping to a minimum to avoid excessive pressure drop. We use a full-flow heat exchanger so no external bypass is needed up to 60 GPM (Gallons Per Minute).

It is also possible, though not recommended, to plumb the solar heating system before the Heat Pump. It is not ideal as the temp of the solar heated water entering the unit may not produce the optimum desired temp by the homeowner.

Please call the Heat Pump Services Department if you have questions about the plumbing order.

MULTIPLE HEATER INSTALL
Multiple heater plumbing must be designed with balancing valves and flow meters to assure at least minimum water-flow to each heater. You will want to consult with our service department for important technical data prior to installation.
A diagram of the system’s flow should be drawn out prior to installation. This will prevent plumbing errors while on site, and help ensure the installation will go quickly.
WIRING MULTIPLE HEATERS TO BE CONTROLLED BY ONE MASTER HEATER 1. Install external 2-pole 24-volt contactor. 2. Wire master contactor low voltage tabs to external contactor low voltage tabs. 3. Run low voltage wire from Heater 2′ s pools/spa terminal on back of board to external contactor, L1 and T1. 4. Run low voltage wire from Heater 3’s pools/spa terminal on back of board to external contactor, L2 and T2.
Pay close attention to different wiring colors to avoid confusing the wires during this set-up. In addition to causing installation delays and aggravation, mismatched or incorrect wiring
may also cause problems with heater operation. 5. Program Remote T-Stat setting to ENABLED on Heater 2 and Heater 3. 6. This system is designed so that when master The Master Heater turns on, it energizes the contactor, causing all sub units to run until The Master Heater shuts off. You may also want to program the time delay on Heater 2 to 6 minutes, and Heater 3 to 7 minutes. This prevents
the units from kicking on all at once, which may cause a power surge. Connecting another external contactor to low voltage tabs of the external contactor, you may wire an additional
heater and all will be controlled by The Master Heater. MULTIPLE HEATER WIRING DIAGRAM LOCATED ON PAGE 16

ELECTRICAL
A qualified electrician must install the electrical power in accordance with local code requirements. Conduit must be run all the way up to electrical box and installed with appropriate connector. Failure to do so voids warranty of electrical components. Running wires as seen in Picture 1 not only allows snakes, bugs, lizards, etc., into box, which could possibly short components, but also poses a direct short hazard where wires penetrate the control box.

Picture 1 – Bad Example

Picture 2 – Good Example

Bugs or lizards getting into board or shorting out the board will not be covered by warranty.

In the bottom of the control box, there is a rubber-piercing plug through which to run low-voltage wiring for external controllers. Simply use a sharp tool, such as a razor, to pierce the plug and run the external control wires through it.

Step One

Step Two

LOCATION OF LOW VOLTAGE WIRES
On the top right-hand corner of the control board, are the connections for outside controllers. Only Dry Contact (no voltage) Connections are to be made here. You may connect external controllers with a thermostat, without a thermostat, flow-switches, etc., to these connections.
caution
Not using the designated area to run your wires can cause safety issues and void warranty. To connect a three-wire controller, use common and either High or Spa, depending on switch,
to these connections and disregard Pool or Low wires.

BONDING THE UNIT
Bonding is often confused with electrical grounding. On the outside of our control box, on the bottom right-hand corner, is a bonding lug. Because all metals have different electrical potentials, all metal and electrical components of the pool system MUST be bonded together.
Check all local and state code requirements.
Damage caused by incorrect or no bonding will not be covered by warranty.

EVEN-HEAT FEATURE ON POOL/SPA
OPTION 8: Even-Heat (Default is “Disabled”) When enabled, this feature is activated when Water Pressure Switch, (WPS) is sensed open for more than 1 minute. The WPS being open for more than 1 minute serves as an indication to the control board that the external timer has timed out and pump has been shut off. This feature is meant to periodically turn the pump on based on the Even- Heat Delay setting and circulate the water. Time interval options are: 1 Hour, 2 Hour, 3 Hour, 4 Hour, Default, and Off. The water circulation distributes the heat evenly and control will sample water temperature to find out if there is a need for heating. If there is a need for heating, the heat pump will heat until temperature set point is reached. The pump will then be de-energized and the Even-Heat timer will reset. If there is no call for heat when the pump is turned on, the pump will shut off after a 5-minute time delay and the Even- Heat timer will reset.
During Even-Heat time delay if WPS is sensed closed then Even-Heat Feature is canceled. The Even-Heat Delay setting remains per user setting in the set up menu. Even-Heat is activated when WPS is sensed open again for more than 1 minute.
In case the water flow switch does not close on the second attempt, control will then display “EVEN-HEAT, LOCKOUT” and stop outputting. The user will have to reset power to the heat pump to unlock the control. Protection features with regard to the state of WPS, LPS and HPS apply when compressor is running.
INSTALLING AN EVEN- HEAT FEATURE To install an Even Heat Feature, wire an extra contactor in parallel with time clock (See Wiring Diagram, Pg. 18). Wire low voltage side of contactor to control board marked “Pump” (See Wiring Diagram, Pg. 18). Set desired Time Interval that you would like the heater to check the water temperature.
See the Even-Heat Feature wiring diagram on Page 18 of this manual.
Incorporting the Even-Heat Feature will change the efficiencies of your Heat Pump operation.
