Options for protecting devices and cable specification
※Above data is subject to modification without notice.
Note: The above data is adapted to power cord ≤ 10 m. If power cord is ＞10 m, wire
diameter must be increased. The signal cable can be extended to 50 m at most.
1. 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.
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 haulted;
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.
Please hold the drainage nozzle (accessory) into the hole and attach it well, then connect a
pipe to drain the condensation water out.

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 according to the circuit diagram.
4) NorthFlo VS 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 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 (PSNF50VS-PSNF65VS).
2．For top fan models (PSNF110VS-PSNF140VS), 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.

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 will be damaged;
B. The user should start the water pump, and check for any leakage of water; Power on
and press the ON/OFF bottom of the heat pump, and set suitable temperature in the
thermostat.
C. In order to protect the pool heat pump, the heater is equipped with a time lag starting

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 cut 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.
IX. Maintenance
A．In winter season when you don’t swim:
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.
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.
