2. Installation and Requirements
The swimming pool heater must be installed by a pool professional. End users are
not qualified to install the heater. Damage may occur to the heater or threaten the
safety of the user. Pool professional guidelines will vary depending on your country,
state or province regulation and can include HVAC technicians or electricians.
Warranty will be voided if done otherwise.
A. Installation
1) The swimming pool heater should be installed in a location with good ventilation;
2) The frame must be fixed by bolts (M10) to concrete foundation or brackets. The
concrete foundation must be solid and fastened; the bracket must be strong and
antirust treated;
3) Don’t stack substances that will block air flow near inlet or outlet area, and no
barrier within 20in behind the main heater, or the efficiency of the heater will be
reduced or even halted;
4) The heater needs an appended pump (Supplied by the user). The recommended
pump specification-flux: refer to Technical Parameter, Max. lift ≥10m;
5) When the heater is running, there will be condensation water discharged from the
bottom. Attach the drainage nozzle (accessory for MI500-MI650-MI900 models)
into the hole under the unit, then connect the pipe to drain the condensation water
out.
Ｂ．Wiring
1) Connect to appropriate power supply; the voltage should comply with the rated
voltage of the products.
2) Heater must be grounded.
3) Wiring must be handled by a professional technician respecting circuit diagram.
4) Moov Inverter units do not require a GFCI to function. If required by code, please
respect following guidelines.
i. Set GFCI according to the local code for wiring (current leakage ≤ 30mA).
ii. Some GFCI breakers may cause nuisance trips with variable speed
products. Consult a certified electrician, your retailer or Moov to confirm
wiring. Product Warranty does not cover electrical wiring.
5) The layout of power cable and signal cable should be orderly and not interfere

9
with each other.
C．Switch on after finishing all wiring construction and re-checking.
Pay attention to the following points:
1． The heat pump must be installed OUTSIDE in a well ventilated area to avoid air
recirculation, or in a place with adequate room for both installation and
maintenance. Please refer to the following illustration for side fan models (MI500-
MI650-MI900).
2． For top fan models (MI1100-MI1400), clearance above the unit should be 8’
unobstructed and 20’’ around.
A minimum of 20’’ of clearance from walls, shrubbery, equipment, etc. is required around the entire
pump circumference. This allows for ample air intake. No less than 8’ clearance on the air outlet
is required to prevent recirculation of air. We recommend to not place the unit underneath eaves,
decks, or porches, as this causes recirculation of discharged air, or the efficiency of the heater
will be reduced or even stopped.
The unit shouldn’t be installed in a confined space or an area with poor ventilation

VII. Testing
１．Inspection before use
A. Check installation of the entire heater and pipe connections
according to the pipe connecting drawing;
B. Check the electric wiring according to the electric wiring diagram;
and grounding connection;
C. Make sure that the main heater power switch is off;
D. Check the temperature setting;
E. Check the air inlet and outlet.
２．Trial
A. The user must start the water pump before the heat pump, and turn
off the heat pump before the water pump, or the heat pump could
be damaged;
B. The user should start the water pump, and check for any leakage
of water. Power the heat pump on by pressing the ON/OFF button
of the heat pump, and set suitable temperature in the thermostat.
C. In order to lower the electrical surcharge, the heater is equipped
with a timer delayed starting function. When starting the heater; the
fan will start 1 minute earlier than the compressor;
D. After the pool heat pump starts up, check for any abnormal noise
from the heater.

14
VIII. Precautions
１. Attention
A. Avoid overheating and set to get comfortable water temperature.
B. Do not stack substances that can block air flow near inlet or outlet
area as the efficiency of the heater will be reduced or even stopped.
C. Do not put hands near the water outlet in the swimming pool, and
don’t remove the screen of the fan at any time;
D. If there are abnormal conditions such as noise, smell, smoke,
electrical issues or leakage, please switch off the machine
immediately and contact the local dealer or Moov Pool Products.
Don’t try to repair it yourself;
E. Don’t use or stock combustible gas or liquid such as thinners, paint
and fuel to avoid fire;
F. In order to optimize the heating effect, please install heat
preservation insulation on pipes between swimming pool and the
heater. During running period of the swimming pool heater, please
use a recommended cover on the swimming pool;
G. Connecting pipes of the swimming pool and the heater should be
≤10m, or the heating effect of the heater cannot be ensured;
２. Safety
A．Please keep the main power supply switch far away from the
children;
B．When a power stoppage happens during running, and later the
power is restored, the heater will start up automatically. So please
switch off the power supply when there is a power cut, and reset
temp when power is restored;
C．Please switch off the main power supply in lightning and storm
weather to prevent from machine damage that caused by lightning;
D．If the machine is stopped for a long time, please cut off the power
supply and drain water clear of the machine by opening the tap of
inlet pipe and outlet pipe.

15
IX. Maintenance
A． In winter season or in the off-season
1. Cut off power supply to prevent any heater damage
2. Drain water clear of the heater.
3. Cover the heater body when not in use.
B．Please clean the heater’s coil with household detergents or clean
water, NEVER use gasoline, thinners or any similar fuel. This will ensure
a good air flow.
C．Check bolts, cables and connections regularly.
X. Trouble shooting for common faults
Failure Reason Solution
Swimming pool
heat pump does
not run
No power Wait until the power recovers
Power switch is off Switch on the power
Fuse burned Check to change the fuse
1. “Cut off” power supply of the heater before cleaning, examination and repairing
2. Do not touch the electronic components until the LED indication lights on PCB
is off/ turn off.
Caution: Danger of electric shock
Important:
Unscrew the water nozzle of inlet pipe to
let the water flow out.
