Swimming pool or spa

3.2 REFRIGERANT TYPE AND INSTALLED LOCATION

This heat pump contains R32, which is an environmentally friendly refrigerant with a GWP (Global Warming Potential) of 675. R32 has the safety in use classification of A2L, being low toxicity and lower flammability. In practical terms it is very difficult to ignite an A2L refrigerant, but this classification requires a risk assessment to be undertaken for the possibility of refrigerant being released by accident into an area connected to the heat pump, considering the application, location of components, and the installed refrigerant charge. This installation guidance can form the framework for such a risk assessment for the installation.

All flammable refrigerants will not ignite if the concentration level in a room stays below their lower flammability limit (LFL). European standard EN378 defines requirements to remain far below the lower flammable limit in case of accidental leakage. By choosing the location as dictated by EN378-1:2016 the probability of forming a flammable atmosphere can be eliminated. Please refer to the minimum area for each product and the interpretation below regarding locations of heat pump and swimming pool. This information is provided as a guide only and does not supersede the regulations or health and safety requirements.

3.4 PLUMBING

IMPORTANT

Before installing the heat pump ensure the blanking disks are removed from the pool water in/out connections. These should drop out when the adaptors are unscrewed.

1. Ensure that bypass is installed and set to achieve the recommended flow rates stated in the data sheet.
2. Ensure that the condensate drain kit supplied is fixed and is drained to a drain or soak-away. (It is best to do this first before the heat pump is fixed to pipework or the ground).

1. Inlet and outlet pipework must be supported to avoid excessive strain on the connections.
2. Water quality must be maintained. See warranty conditions.

3.5 INITIAL CHECKS

Start the filtration pump before the heat pump is turned on and turn off the heat pump before the filtration pump. It is recommended to turn off the heat pump prior to backwashing.

Before starting the heat pump, please check for any leakage of water; and check/set the required temperature on the controller, and then turn on.

In order to protect the components, the heat pump incorporates time delays. When starting heating/cooling the fan will run for one minute before the compressor starts. The heat pump runs for a minimum of 5 minutes. When the heat pump stops heating/cooling, or is turned off by the user, the fan will continue to run for one minute.

After starting up, check for any error codes or abnormal noise from the heat pump.

3.6 ELECTROLYTIC CORROSION IN SWIMMING POOLS

Electrolytic corrosion will occur when dissimilar metals that are in contact with each other create a potential difference between themselves. Sometimes separated by a conductive substance known as an electrolyte, the dissimilar metals will create a small voltage (potential difference) that allows the ions of one material to pass to the other.

Just like a battery, ions will pass from the most positive material to the more negative material.

Anything more than 0.3 volts can cause the most positive material to degrade.

A swimming pool with its associated equipment can create this effect. The pool water being an ideal electrolyte and components of the filtration circuit, heating system, steps, lights etc providing the dissimilar metals needed to complete the circuit.

Whilst these small voltages are rarely a safety threat, they can create premature failure through corrosion. Not dissimilar to corrosion through oxidation, electrolytic corrosion can cause complete failure of a metallic material in a very short period of time.

In order to prevent this type of corrosion all metallic components in contact with swimming pool water should be bonded together using 10mm^2 bonding cable. This includes non-electrical items such as metal filters, pump strainer boxes, heat exchangers, steps and handrails. It is highly recommended that bonding be retrofitted to existing pools, which may not be protected by this system.

All electrical work to be carried out in accordance with I.E.E.regulations, latest issue, or local codes of practice

3.7 ELECTRIC WIRING AND SUPPLY

as applicable..

The machine should be installed in accordance with EMC2004/108/EC.

Always isolate the main owner supply before removing machine covers.

The machine power supply must incorporate the following. Fuses or motor type circuit breakers (aM Fuse / MCB type C) to specified rating (see datasheet). When using a fuse, H.R.C. fuses are recommended. An isolator which disconnects all poles must be must fitted within 2m and in line of sight of the heat pump. The isolator must have a minimum of 3mm air gap when turned off.

All units must be correctly earthed/grounded and its own separate type F RCD earth leakage trip installed which protects the machine only.

The following limits of operation must not be exceeded. Failure to provide the necessary voltages will invalidate the warranty. This voltage must be available at the heat pump whilst running. The voltage must not drop below the above figures when starting the compressor.

Minimum Maximum

Voltage

Single phase machines 207V 253V

Cycle frequency (50Hz) 47.5Hz 52.5Hz

3.8 CONNECTING THE HEAT PUMP TO THE POWER SUPPLY

For installations where the pool filter pump runs continuously, these terminals do not need to be used.

For installations where a timeclock controls the pool filter pump, and the same pump provides water flow to the heat pump, the heat pump can override "pump off" periods to ensure the pool is heated/cooled. To activate this setting please speak to your installer.

When installed in parallel with the timeclock, the pool filter pump will run when:

a) a period of "pump on" has been set on the time clock for filtration purposes.
b) a period of "pump off" has been set in the time clock and the heat pump runs the pool filter pump for temperature sampling and if the pool subsequently requires heating/cooling.

This feature operates by over-riding the timeclock whenever the controller measures a water temperature

that needs heating/cooling. If the pool does not need heating/cooling the filter pump will be turned off until the controller next measures a water temperature that needs heating/cooling. If the pool needs heating/ cooling the heat pump will continue to run the filter pump and heat/cool the pool.

This feature will reduce the pool filter pump run time to minimise pump energy usage.

Note: When the heat pump is powered off, the display shows the time.
