Safety
Hazards When Handling the Heat Exchanger
BOWMAN® “Swimming Pool Heat Exchangers” are constructed in accordance with current practice and recognized safety rules. Hazards may still arise from operation, such as:
- Injury of the operator or
- Third parties or
- Damage to the heat exchanger or
- Damage to property and equipment
Any person involved with the installation, commissioning, operation, maintenance or repair of the heat exchanger must be:
- Physically and mentally capable of performing such work
- Appropriately qualified
- Comply completely with the installation instructions
The heat exchanger must only be used for this purpose.
In the event of breakdowns which may compromise safety, a qualified plumber
must always be contacted.

This symbol indicates important information about correct handling of the equipment Failure to comply with this instruction may cause damage to the heat exchanger and/or its surroundings.
Approved Use
BOWMAN® “Swimming Pool Heat Exchangers” are only approved for heating or
cooling pools with boiler water, solar and heat pump systems.Any other use
unless agreed by BOWMAN® is not approved. We decline all liability for damage
associated or arising from such use.
The maximum working pressure is:
Heating/Cooling Side : 6 bar
Pool Water Side : 6 bar
The maximum working temperature is :
Heating/Cooling Side : 110 ºC
Pool Water Side : 100 ºC
Potential Hazards
Take Care
The heat exchanger may be damaged or leak if the maximum working pressure is exceeded.
Connections on the heating water side of the heat exchanger may reach temperatures as high as 110ºC.
Caution
The heat exchanger may heat up to the flow temperature of the heating water if there is no pool water flowing through the heat exchanger. Any plastic pipe work may be exposed to excessive temperature and suffer damage.
Safety Measures at Installation Site
Take Care
The heat exchanger should be installed in a frost free enclosure.
Ensure the maximum working pressure on either side of the heat exchanger is not exceeded or the heat exchanger or surrounding equipment may be damaged.
While the pool is in operation, weekly inspection of the heat exchanger and its connections should be made to check for leaks and external damage.
Installation
Transport / Storage
The heat exchanger must be drained prior to transportation. Once drained and dry, the heat exchanger must only be stored indoors in a non-aggressive atmosphere.
Installation
The heat exchanger should only be installed in a frost-free, dry area with a non aggressive atmosphere. Ensure easy access for assembly/disassembly.
Fitting
Before fitting, check the heat exchanger for damage, the heat exchanger can be installed above or below the pool water level, positioned horizontally or vertically, as shown below.
Horizontal Mounting
The heat exchanger may be damaged by chemicals. Dosing systems must be fitted downstream from the heat exchanger incorporating a non return valve. If chemicals are used, gases must be prevented from entering the heat exchanger when the filtration system is not in use.
The heat exchanger should always be installed downstream of the pumping and filtration equipment. The boiler/solar water must be pump assisted and the usual precautions taken to prevent air locks. It is recommended that an inhibitor is added to the boiler circuit to protect the system against corrosion.
The heat source should be controlled by a thermostat in the pool water pipe before the heat exchanger and set at the required pool temperature.
Connecting the Heat Exchanger
Close all isolating valves in the flow and return pipes of both circuits.
Ensure compliance with water quality and maximum permissible pressures.
When fitting the heat exchanger into the pipe work care must be taken to ensure that no debris has been introduced into the heat exchanger.
Please refer to the table below for the pool water and boiler/solar water connections.

Important pool water connection information
EC heat exchangers; feature ‘Universal Fit’ end covers designed to
accommodate both metric and imperial pipe. For metric 50mm (DN40) pipe, there
is a 28mm deep recess to secure the pipe to the end cover. For imperial 1½”
NPS pipe, there is a 56mm deep recess to secure the pipe to the end cover.
When installing 1½” NPS it is important to locate sufficient pipe length into
the full recess in order to ensure a water tight seal between the pipe and the
end cover. Please refer
FC heat exchangers; are supplied with adaptors which enable either 63mm
(DN50) metric pipe, or 2” NPS(60.3mm) imperial pipe to be used. There is a
38mm deep recess to secure the pipe in the end cover for both pipe sizes.
Please refer to diagram for more information.
FG & GL heat exchangers; when connecting an FG or GL heat exchanger to
the pool water, always ensure that sufficient connecting pipe thread goes into
the end cover to enable it to engage with the black coated thread. This
prevents the uncoated thread being exposed to the pool water.
Counter flow installation
The heat exchanger must be installed in counter flow – i.e. where the pool
water flows in the opposite direction to the heating water as shown below
NOTE: failure to install the heat exchanger in this arrangement will reduce the performance.
Integral thermostat pocket
Most Bowman swimming pool heat exchangers have an integral thermostat pocket. To ensure accurate monitoring of the pool water temperature it is important to install the thermostat on the pool water inlet to the heat exchanger.
Operation
It is essential that the following instructions are followed to prevent corrosion/erosion of the heat exchanger:
a) BOWMAN® Stainless Steel heat exchangers should not be used with salt water chlorinators or salt water pools. ( Cupro Nickel or Titanium is available for these applications).
b) Always maintain the water pH to within correct levels. The ideal pool pH should be kept within 7.4 to 7.6. On no account should it fall below 7.2 or rise above 7.8. Checks should be made daily. Recommended chemical limits for BOWMAN® Swimming Pool Heat exchangers are shown below, however any local swimming pool water guidelines should be followed for safe bathing.
| Material | Cupronickel | Stainless Steel | Titanium |
|---|---|---|---|
| Free Chlorine | 1.0 – 3.0 ppm | 1.0 – 3.0 ppm | 15.0 ppm max. |
| pH | 7.2 – 7.8 | 7.2 – 7.8 | 6.8 – 8.0 |
| Calcium Hardness | 200 – 400 ppm | 200 – 1000 ppm | 200 – 1000 ppm |
| Alkalinity | 100 – 150 ppm | 100 – 150 ppm | 100 – 150 ppm |
| Bromine | 2.0 – 4.0 ppm | 2.0 – 4.0 ppm | 15.0 ppm max. |
| Chloride | Less than 150 ppm | Less than 350 ppm | Less than 3000 ppm |
c) If a by-pass is fitted, it is essential that any valves are positioned to allow the recommended pool water flow to pass through the heat exchanger.
d) The filter unit should be checked regularly, especially if sand filters are used. If sand filters are not working correctly, fine particles of sand can flow round the pool circuit causing erosion of the pipe work, heat exchanger and pump
e) Keep the pool free from debris such as leaves, grass cuttings etc. Foreign matter can decay and increase the pH level in the pool.
f) It is essential that the correct amount of chemical is added to the pool. To allow proper dispersion of the dose in the pool water, distribution of the dose should be made to various areas of the pool. Do not dose in one area only, especially adjacent to the pool water return as this will create high acidic areas which can cause corrosion/erosion of the pool equipment.
Commissioning
Take Care
Commissioning of the heat exchanger should not be undertaken until this document has been read and understood.
Danger
Both circuits of the heat exchanger must be connected before commissioning.
Adequate provision should be made to ensure that correct operating equipment along with personal protection (PPE) in accordance with current standards is used.
Maintenance / Repair
Winter Shutdown in Frost Free Areas
When shut down in frost free premises the heat exchanger must be completely full of water and purged of air.
Winter Shutdown in Areas Exposed To Frost
Care should be taken to prevent frost damage from a winter shutdown in premises exposed to frost. We recommend draining the heat exchanger or removing it from the installation for the shutdown period.
General Maintenance
The heat exchanger should require little attention in service, however if cleaning or replacement of the tube stack is necessary the end cover screws should be tightened to the torque figures below. Note, new seals are recommended if the end covers are removed.
