1. General information 1.1 Introduction This manual provides installation and operation instructions for EVOHEAT heat pumps. Read these installation and operation instructions carefully before proceeding with the installation and operation of your heater. Consult your EVOHEAT Distributor with any questions regarding this equipment. Installation and service must be performed by a qualified installer.

CHAPTER 1 INSTALLATION Before installation it is very important to ensure 4 variables are carefully checked to allow the unit to operate correctly 1. Adequate Air Flow 2. Correct water flow volume 3. Correct electrical connection & supply 4. Heater condition 1. Air Flow Installing the heater indoors or in an enclosed space will result in very poor performance and can in extreme cases damage the heater.
4. Heater Condition Check the heater packaging upon delivery for any obvious signs of damage. Inform your supplier IMMEDIATELY if there is any evidence of rough handling. When the heater has been removed from the packaging check the refrigerant gauge on the front panel of the unit. The gauge should be showing a pressure of approx 1Mpa on the outside black band – any less than this figure means there may be a leak in the refrigerant system and you should immediately contact your Evoheat Dealer.
3.2 Location Evo recommend the heat pump should ONLY be installed in an outdoor location with appropriate ventilation. In the event that a suitable outdoor location is unavailable contact Evo Industries for specialist technical advice. If installing the heater on an existing pump/filtration system the heater must be installed AFTER the filter and BEFORE the chlorinator/sanitizer. The heat pump should be installed on a flat level surface as close as possible to the pool.
3.4 Water Flow and Plumbing Setup All EVOHEAT heat pumps have a factory preset internal water flow switch. If there is insufficient water flow the heater will not operate. Before connecting the heater to the plumbing, all piping must be thoroughly flushed to ensure no debris can enter the heater. Failure to remove pipe debris can jam or damage the flow switch and may cause damage to the heater.
3.5 Drainage Whilst the heater is operating, water in the air condenses on the fins of the evaporator. In the instance of high humidity, the condensate may be several litres per hour. This may give the impression that the heater is leaking, however this is a normal function of heat pumps. The heater will automatically activate reverse cycle or de-icing mode when required which also increases condensate discharge. This normally occurs at temperatures below 8 degC.
3.7 Water Pump Connection There are 2 methods to install an Evo heat pump. 1. EXISTING FILTER PUMP/CHLORINATOR/TIMER CONTROLS THE HEATER 4 Integrated Operation – Ideal mode for retro fit to existing filter/pump set ups. Operation of the filter pump controls the heater start and shut down timing. 2. HEATER CONTROLS A DEDICATED WATER PUMP This option is required for Programmed Options modes. This water pump is installed for heater circulation only.
d. Then press the ON/OFF button on the remote controller. The heater will start shortly after water flow commences. Actual conditions can be checked by going to the MAIN menu and selecting UNIT status to view water inlet and outlet, refrigerant pipe and ambient air temps. e. After the unit runs for a few minutes, check whether the air discharged by the fan is noticeably cooler than the ambient air.
d. Press the ON/OFF button on the remote controller. The water pump will start when the time reaches the TIMER ON setting and the heat pump will start 60 seconds after this value. The heat pump will shut down when it reaches the TIMER OFF value and the water pump will shut down 30 seconds afterwards . Actual conditions can be checked by going to the MAIN menu and selecting UNIT status to view water inlet and outlet, refrigerant pipe and ambient air temps. e.
CHAPTER 2 Button 1. OPERATION Description and Operation On/Off Button Press this to turn the unit on or off. Status will be STANDBY mode when heater is off. 2 & 4. Up/Down Selection Buttons Use to modify data while heater is in standby mode. Use to view data while heater is running. 3. Prg Button Used to access controller menu options. 5. Esc Button Used to confirm changes to menu settings. 6. Used in view mode to move back through the menu options.
There are 2 operating modes for your heater. Follow the instructions below for Quick setup. 4.1 EXISTING FILTER PUMP/CHLORINATOR/TIMER CONTROLS THE HEATER 1. Ensure the heater is in STANDBY mode 1 OFF 2. Set the mode to HEAT - Press 6 from MAIN MENU>MODE SELECT>COOL/HEAT If the pool requires cooling please select cool mode 3.
4. Turn the heater ON 5. The heater will turn on and off according to times set on your (A) chlorinator or timing device (B) the temperature set on the controller once reached At initial startup the water pump may need to be in operation for several days to allow the heat pump to heat the pool to the desired temperature. The operation time of the water pump may also need to be adjusted from winter to summer to ensure adequate time to heat the pool.
Programmed Options – “Timer” Mode This mode gives you precise control over your heater start and stop times 7 days a week. To gain the most efficiency out of your heater, use the timer to run the heater in the hottest part of the day, say 9am – 6pm. This may mean your pool isn’t at the perfect temperature at 3am in the morning for a late night dip, or an early morning swim. This is the most efficient running mode.
4. Set the current date and time and the required heater start and stop time from TIME submenu 5. Change the Pump from NORMAL to SPECIAL mode from PARAMETER>PUMP Page down the parameter menu to find the last screen. NORMAL pump mode means the water pump will run 24 hours continuously while the power is on to the heater. SPECIAL pump mode means the water pump will turn on 60 seconds before the compressor in the heat pump switches on and shut off 60 seconds after the compressor switches off.
6. Turn the heater ON 7. The heater will turn on and off according to times set in step 4 above. If the heater reaches the HEAT/COOL TEMP value entered in step 3 above the heat pump will turn itself and the water pump off and wait for the water temperature to drop by 1 degree from the set point. The heater will then restart providing the actual time is within the set start and stop values.
1. Follow all instructions in Programmed Options – “Timer” Mode menu above. 2. Set the TIME ON and TIME OFF values to 00:01 and 00:00 respectively. By setting the timer to allow the heater to run 24 hours a day you can “set and forget” the operation of the heater. The heater will turn on the water pump, run until it reaches the desired water temperature and then switch itself and the water pump off.
Maintenance and Troubleshooting 5.1 Maintenance General Maintenance a. The unit should be serviced once a year by a authorised EVO technician. If the unit is located in a coastal area, more frequent maintenance may be necessary. b. The unit is designed to withstand only normal rainfall. It is NOT recommended to use a hose or high pressure water cleaner to flush the internals of the heater. Pressurised water may cause damage to the heater.
The unit is running but not heating a. Is the fan functioning? If not contact EVOHEAT for service information b. Is the air discharged from the top of the fan noticeably cooler than the ambient temperature? If not, check the refrigerant gauge on the bottom panel of the heater. Another way to determine if the heater is working correctly is to view MAIN MENU>UNIT STATUS. Check to see if the WATER OUT temp is higher than the WATER IN temp.
