Setting Up
- The Outer dial will need to be set to the current time (when the heater
has been installed and has a constant power supply). Rotate the minute hand slowly
in a clockwise direction, until the correct hour is located at the tip of the arrow
printed on the dial. See Figure 1 below.
Please note that the outer dial is printed with the 24 hour clock i.e. 8:00 am = 8 on
the dial. 8:00 pm = 20 on the dial.
Programming Switching Times
- Once the outer dial has been set to the current
time you will need to position the appropriate tappets to your required on and off
times. The factory set position of all tappets is in the off position, to change any
tappets to the on position they must be switched away from the clock face.
See Figure 2 Below.
Manual Override
- Your 24-hour timer is also fitted with a manual override
switch that is built into the face of the dial illustrated in Figure 1 (top of page). This
switch has 3 positions which are explained in the table on the following page.

Upon completion of the installation, run the water-circulating pump to purge the
system & heater of air (i.e. Remove any trapped air in the system & heater).
On initial power up of the heater the amber light should illuminate. Only when the
water circulating pump is operational and delivering in excess of 1,000-litres per
hour of flow (220 UK gallons), and the temperature set point dial is set to a value
higher than that of the water temperature will the red indicator light click on and the
amber indicator light off. In this mode the heater is on and heating.
Q = How long will it take to heat my pool?
A =
Assuming no heat losses
, and a heater sized in the ratio 1.5-kW per 1,000-
gallons of water (4,545-litres): it will take 2 days of continuous running to raise the
temperature of a pool from tap temperature to swimming temperature.
Heat loss will slow the heating process, particularly during periods of cold weather,
hence the higher the water temperature is to be maintained above average ambient
air temperature, the slower the heating process will become. The only influencing
factors are the level of insulation and the sighting of the pool with regard to wind
shelter.
Important
- The manual override positions are a
fixed
selection - i.e. the output of
the 24 hour timer will remain ON or OFF (as selected), until the switch is returned
back to the
¥
(middle) position.
Useful advice: To reduce running costs and speed up the heating process ;
Insulate the pool wherever possible. A floating solar cover is an essential
minimum to retain heat.
