HOW TO DERTERMINIE THE RIGHT POWER RATING OF
YOUR VAL THERM POOL HEATER
The following factors will influence the power needed for your pool heater: Pool
dimension, average depth, wind exposure, period of utilization, ground
composition, weather, etc...
With normal weather conditions as in our regions, we will be able to determine
the power needed for your pool heater, based on empirical method or
mathematical formulas.
EMPIRICAL METHOD
Our experience shows that according to your utilization period, the power for
your Heater should be as follow:
•4 months utilization: 1.0 kw per 4500 litres
(1000 imperial gallons)
•5 months utilization: 1.5 kw per 4500 litres
(1000 imperial gallons)
•6 months utilization: 2.5 kw per 4500 litres
(1000 imperial gallons)
_______________________________________________________
4500 liters = 1000 imperial gallons

MATHEMATICAL METHOD
You can determine your heater power and also weather elevation rate for a given
heater by applying this formula:
•How to establish the heater power:
Power (KW) = K (W/°Cft²) X temp.diff. (°C) X surfpool. (pi²)
1000 (W/KW)
K: Conversion constant: 5.715 W/°ft²
Temp. Diff.: Temperature spread between water surface and
ambient air. Normal use is generally between
5°C and 8°C.
K:
•How to determine temperature elevation rate:
Elevation (°C/hour) = K (°Cft³/KWH) X Power (KW)
Surf.pool (ft²) X av.depth (ft)

6-TERMINAL BLOCK
Terminal block for electricity supply
7-STATIC CONTACTOR
Allow the activation of the heating elements. Contactors are engage through
the thermostat.
8- TRANFORMER CONTROL
Only used for the 600 volts Water-heater. Allows supply the solenoid
contactor.
9-TIME CONSTANT
Allows a sequential activation of the heating elements (Water-heater with
208 and 240 volts with 21kw of power or more).

Component List
10- BRAKER
Protects the control circuit against electric overloads.
(600 volts and 208 volts Water-heater only)
11-GROUND BOX
Make sure that the ground box is in the ground to prevent any electrocution.
12-THERMAL PROBE
When water is inferior of the temperature assign, it allows the activation of
the elements though the thermostat.
13-HEATING ELEMENT
Triple phased 600 volts element, with a power 6 or 9 kw.
14- HEATING ELEMENT
Single phased 240 volt element, with 3kw power.
15-OPENING
1½`` diameter opening allowing the passage of alimentation cables.
16-THERMAL PROTECTION
High temperature circuit breaker with automatic reengagement.
17-TERMAL PROTECTION
High temperature circuit breaker with manual reengagement.
18-PRESSURE SWITCH
A cut-off switch when water is low.

TROUBLESHOOTING
If water stays cold and pilot light is off:
1- Check the voltage
2- Check circuit breaker, main fuses and replace if necessary
3- Check the “High Temperature Cut off Switch with Manual Reset’’ (refer to the
physical diagram).
4- Check thermostat.
5- For the 600 volts water-heater, checks the circuit breaker located in inside the
control box and if necessary, replace it.
If water does not heat as wanted and pilot light is on:
1- Check voltage
2- Check thermostat
3- Check heating elements. You should obtain the following readings in regards
of elements type:

INSTATALLATION - LOCATION SITE
This Val Therm water heater can be installed either inside or outside. We
strongly recommend sheltered from rain. It is important that all safety and
installation standards be respected.
The water heater must be positioned vertically and at the filter end. A free space
of 12’’ all around the heater must be accessible for maintenance.
ELECTRICITY
The electrical wirings must be performed by qualified electrician.
PLUMBING
The inlet and outlet of the pool heater are connected to two 1 ½” N.P.T. threaded
cap is included with all models for emptying convenience.
Note: Use only Teflon tape to assure water tightness of pipes connections.
Tight pipes properly, and use tools when necessary, ex: Pipe wrench.

ELECTRICITY
The electrical wirings must be performed by qualified electrician.

STAR UP
1- Before switching on pool heater, activate the pump of the filter and ensure that no air remains
inside the water heater. This can be checked when no more bubbles appear at the pool when water
recycles back to the surface.
2- Adjust the thermostat to the desired temperature level. The time to reach the desired
temperature varies, depending on initial temperature of the water, weather conditions, etc...
3- For security, two reset buttons protect the machine against high temperature elevation 120 C°,
the reset button shot off automatically the circuit, so you have to restart by pushing the red button.
The third security, It’s a pressure switch for the lower water pressure in the water thank. This unit
require a minimum flow of 35 gallons per minute.
4- Maintain proper water chemical balance: pH level: 7.4, alkalinity: 120, salinity: 180-260,
otherwise internal parts may deteriorate prematurely, those damages are bit covered by the
warranty. Do not send water through the water heater until it is balanced (see bypass diagram)
Test the water and balance it every week.
5- Tank should be full of water before starting up, otherwise permanent damage to parts occurs.
Such damage is not covered by the warranty.
WINTERIZING
Empty heater tank draining plug to prevent water freezing inside tank during winter.
SAFETY
Before opening the pool heater, make sure it is not plugged in.
This unit require a minimum flow of 35 gallons per minute.
Part replacement with original only
Do not install two heaters on the same line because it could lower the water pressure and cause
damage.
If you install a timer on the pump and/or the filter, there needs to be a 240 volts timer on the water
heater do that this one shuts down 30 minutes before the one on the pump and/or filter
