Electric heater Maxi Heat Digital
Pahlén electric heater Maxi Heat with digital control is a compact and effective heater for swimming pools. It consists of a glass-
fibre reinforced polypropylene tank containing resistance-type heating elements made of Incoloy 825 or titanium.
If the pool water is aggressive, salt or in pools where a salt chlorinator is used, a heater with heating elements made of titanium
is required.
An electronic thermostat controls the pool water temperature (max. +45°C) and four indicator lights show when the heating
element is operating.
The heater is available in outputs from 18kW to 60kW for 230V, 16,2kW to 78kW for 380V or 400/415V. Check the rating plate
placed on the back of the heater for relevant information.
Safety
The heater must be installed in accordance with all local codes, ordinances and utility company requirements.
The heater must not be covered, enclosed in or placed near inflammable material or placed in direct sunlight.
Built-in safety controls in the heater are a flow switch and a manual reset overheating limit control to protect against over-
heating and element burn-out. The heater has also built-in automatic fuses. The heating element is controlled by an electronic
thermostat to provide a safe and satisfactory swimming pool temperature.
Do not in any circumstances energize the heater until certain it's filled with water.
"Appliance is not to be used by children or persons with reduced physical, sensory or mental capabilities, or lack of experience
and knowledge, unless they have been given supervision or instruction. Children being supervised not to play with appliance"
(IEC 60335-1/A2)
General info
Follow these instructions:
Installation
Make the plumbing before the electric installation. Place the heater so that the service door (the opposite side to the one with
the drain plug) and the top lid can be opened. Fasten the heater in the foundation by the four Ø13 holes in the base.
Recommended water flow through the heater is 170-300 l/min. If flow rates are higher than 300 l/min, a bypass should be
installed and adjusted to obtain the recommended flow through the heater. A check valve should be installed after the heater
outlet and a drain valve ahead of the heater inlet to allow for heater maintenance without draining the swimming pool. Install
unions to permit easy removal of the heater for inspection, cleaning and service.
