3.2 Swimming Pool Heat Pumps Location
The unit willperform well inany outdoor locationprovided that thofollowlng threo factorsare
presented:
1. Fresh Air - 2, Electricity - 3. Pool filter piping
The unit maybe installed virtuallyanywhere outdoors. Forindoor pools pleaseconsult the
supplier. Unlikea gas heater, it hasno.draft orpilot light problemin a windyarea.
DO NOTplace the unitin an enclosedarea with alimited air volume,where the uniis

estimate of heat loss per 30 meters is 0.6 kW-hour,(2000BTU)for every 5 C difference in
temperature between thepool water andthe ground surroundingthe pipe, whichtranslates to
about 3% to5% increase inrun time.

3.4 Swimming Pool Heat Pumps Plumbing
The Swimming PoolHeat Pumps exclusive rated flow titanium heat exchanger requires no
special plumbing arrangementsexcept bypass(please setthe flow rateaccording to the
nameplate). The water pressure drop is less than 10kPa at max. Flow rate. Sincethere is no
residual heat orflame Temperatures, The unit does notneed copper heatsink piping. PVC
pipe can berun straight intothe unit.
Location: Connect the unit in the pool pump discharge (return) line downstream of all filter
and pool pumps,and upstream ofany chlorinators, ozonatorsor chemical pumps.
Standard model haveslip glue fittingswhich accept 32mmor 50 mm PVC pipe for
connection to thepool or spafiltration piping. Byusing a 50NB to 40NByou can plumb40NB
Give serious considerationto adding aquick coupler fittingat the unitinlet and outletto allow

CONDENSATION
DRAIN
BARB FTG
Condensation: Since theHeat pump coolsdown the airabout 4 -5C, water maycondense on
the fins ofthe horseshoe shapedevaporator. lf the relative humidityis very high,this could
be as muchas several litresan hour.The waterwill run downthe fins inioihe basepan and
drain out throughthe barbed plasticcondensation drain fittingon the sideof the basepan.
This fitting ls designed to accept 20mm clear vinyltubing which can be pushed on by hand
and run toa suitable drain.lt is easyto mistake thecondensation for awater leak insidethe
unit.
NB: Aquick way toverify that thewater is condensation is to shutoff the unit and keepthe
pool pump running.lf the waterstops running outof the basepan, it is condensation.AN
EVEN QUICKER WAYIS toTEST THEDRAIN WATER FOR CHLORINE. if theis no chlorine
present, then it's condensation.

5. MAINTENANCE AND INSPECTION
§åNo ignition sources
No person carrying out work in relation to a refrigeration system which involves exposing
any pipe workthat contains orhas contained flammablerefrigerant shall useany sources
of ignition insuch a mannerthat it maylead to therisk of fireor explosion.All possible
ignition sources, including cigarette smoking, should be kept suficiently far awayfrom the
site of installation, repairing, removing anddisposal, during whichflammable refrigerant
can possibly bereleased to thesurrounding space. Priorto work takingplace, the area
around the equipmentis to besurveyed to makesure that thereare no flammablehazards
or ignition risks. "No Smoking" signs shall bedisplayed.
&Ventilated area
Ensure that thearea is inthe open orthat it isadequately ventilated beforebreaking into
the system orconducting any hotwork. Adegree ofventilationshall continue duringthe
period that thework is carriedout. Theventilation should safelydisperse any released
refrigerant and preferablyexpel it externallyinto the atmosphere.
& Checks to the refrigeration equipment
Where electrical componentsare being changed,they shall befit for thepurpose and tothe
correct specification.At all timesthe manufacturer's maintenanceand service guidelines
shall be followed.lf in doubtconsult the manufacturer'stechnical department for
assistance.
The following checksshall be appliedto installations usingflammable refrigerants:
The chargesize is inaccordance with theroom size withinwhich the refrigerantcontaining
parts are installed;
The ventilationmachinery and outletsare operating adequatelyand are notobstructed;
lf an indirectrefrigerating circuit isbeing used, thesecondary circuit shall be checked for
the presence of refrigerant;
Marking to theequipment continues tobe visible andlegible. Markings andsigns that are
illegible shall becorrected;
Reirigeration pipe orcomponents are installedin a positionwhere they areunlikely to be
exposed to anysubstance which maycorrode refrigerant containing components, unless
the components areconstructed of materialswhich are inherentlyresistant to being
corroded or aresuitably protected againstbeing so corroded.
3 Checks to electricaldevices
Repair and maintenanceto electrical componentsshall include initialsafety checks and
component inspection procedures. lf a faultexists that couldcompromise safety, then no
electrical supply shallbe connected tothe circuit untilit is satisfactorilydealt with. lf the
fault cannot becorrected immediately butit is necessaryto continue operation,an
adequate temporary solutionshall be used.This shall be reported tothe owner ofthe
equipment so allparties are advised.
lnitial safety checks shall include:
. Thatcapacitors are discharged:this shall bedone in asafe manner toavoid possibility of
sparking;
. Thatthere no liveelectrical components andwiring are exposedwhile charging,
recovering or purgingthe system;
. Thatthere is continuityof earth bonding.

5. MAINTENANCE AND INSPECTION
@ Repairs to sealed components
1) During repairsto sealed components,all electrical suppliesshall be disconnectedfrom
the equipment being worked upon priorto any removalof sealed covers, etc. lf it
isabsolutely necessary tohave an electricalsupply to equipmentduring servicing, thena
permanently operating form of leak detection shall be located at the mostcritical point to
warn of a potentially hazardous situation.
2) Particular attentionshall be paidto the followingto ensure thatby working onelectrical
components, ihe casing is not altered in such away that the level of protection is affected.
This shall include damage to cables, excessive number of connections, terminals not made
to original specification, damage to seals, incorrect fitting of glands, etc.
& Ensure that apparatus is mounted securely.
Ensure that sealsor sealing materialshave not degradedsuch that theyno longer serve
the purpose of preventing the ingressof flammable atmospheres. Replacement parts shall
be in accordancewith the manufacturer'sspecifications.
N OTE: The use of silicon sealant may inhibit the effectiveness of some types of leak
detection equipment. lntrinsicallysafe components donot have tobe isolated priorto
working on them.
@ Repair to intrinsicallysafe components
Do not applyany permanent inductiveor capacitance loadsto the circuitwithout ensuring
that this willnot exceed the permissible voltage andcurrent permitted forthe equipment in
use.
lntrinsically safe componentsare the onlytypes that canbe worked onwhile live inthe
presence of aflammable atmosphere. The test apparatusshall be atthe correct rating.
Replace components onlywith parts specified by the manufacturer. Other parts may result
in the ignitionof refrigerant inthe atmosphere froma leak.
@ Cabling
Check that cablingwill not besubject to wear, corrosion, excessivepressure, vibration,
sharp edges orany other adverse environmental effects. The check shall also take into
account the efiects of agingor continual vibrationfrom sources suchas compressors or
fans.
§ Detection of flammable refrigerants
Under no circumstancesshall potential sourcesof ignition beused in thesearching for or
detection of refrigerantleaks. Ahalide torch (orany other detectorusing a nakedflame)
shall not be used.
6 Leak detection methods
The following leakdetection methods aredeemed acceptable forsystems containing
flammable refrigerants.
Electronicleakdetectorsshall beusedtodetectflammablerefrigerants,butthesensitivity
may not beadequate, or mayneed re-calibration. (Detectionequipment shall becalibrated
in a refrigerant-freearea.) Ensure thatthe detector isnot a potentialsource of ignitionand
is suitable forthe refrigerant used.Leak detection equipmentshall be setat a percentage
of the LFLof the refrigerantand shall becalibrated totherefrigerantemployed andthe
appropriate percentage of gas (25 %maximum) is confirmed.
Leak detection fluidsare suitable foruse with mostrefrigerants but the use of detergents
containing chlorine shall be avoided as the chlorine may react with the refrigerant and
corrode the copper pipe-work.
lf a leakis suspected, allnaked flames shallbe removed/ extinguished.
lf a leakageof refrigerant isfound which requiresbrazing, all ofthe refrigerant shallbe
recovered from thesystem, or isolated(by means ofshut offvalves) in apart ofthesystem
remote from theleak. Oxygen freenitrogen (OFN) shallthen be purgedthrough the system
both before andduring the brazingprocess.

5. MAINTENANCE AND INSPECTION
&; Removal and evacuation
When breaking intothe refrigerant circuitto make repairs or for anyother purpose
conventional procedures shallbe used. However, it isimportant that bestpractice is
followed since flammabilityis a consideration.The following procedure shall beadhered to:
. Remove refrigerant;
. Purge thecircuit with inertgas;
. Evacuate;
. Purge againwith inert gas;
. Open the circuit by cutting or brazing.
The refrigerant chargeshall be recoveredinto the correctrecovery cylinders.The system
shall be "flushed"with OFN torender the unitsafe. This process may needto be repeated
several times. Compressed air or oxygen shall not be used for thistask.
Flushing shall beachieved by breakingthe vacuum inthe system withOFN and continuing
to fill untilthe working pressureis achieved, thenventing to atmosphere,and finally pulling
down to avacuum. This process shall berepeated until norefrigerant is withinthe system.
When the final OFN charge isused, the systemshall be venteddown to atmospheric
pressure to enablework to takeplace. Thisoperation is absolutelyvital if brazing
operations on the pipe-work are totake place.
Ensure that theoutlet for thevacuum pump isnot close toany ignition sourcesand there is
ventilation available working on them.
§i Labeiling
Equipment shall belabelled stating thatit has beende-commissioned and emptiedof
refrigerant. The label shall bedated and signed. Ensure that there are labels on the
equipment stating theequipment contains flammablerefrigerant.
Recovery
When removing refrigerantfrom a system,eitherfor servicingor decommissioning, itis
recommended good practicethat all refrigerantsare removed safely.
When transferring refrigerantinto cylinders, ensurethat only appropriaterefrigerant
recovery cylinders areemployed. Ensure thatthe correct numberof cylinders forholding
the total systemcharge is available.All cylindersto be usedare designated forthe
recovered refrigerant and labelled for that refrigerant (i.e. special cylinders for the recovery
of refrigerant). Cylindersshall be completewith pressure reliefvalve and associatedshut-
off valvesin good workingorder. Emptyrecovery cylinders areevacuated and, if possible,
cooled before recoveryoccurs.
The recovery equipmentshall be ingood working orderwith a setof instructions
concerning the equipmentthat is athand and shallbe suitable forthe recovery of
flammable refrigerants. lnaddition, a setof calibrated weighingscales shall beavailable
and in goodworking order. Hoses shall becomplete with leak-freedisconnect couplings
and in goodcondition. Before usingthe recovery machine,check that itis in satisfactory
working order, has been properly maintained and thatany associated electrical
components are sealedto prevent ignitionin the eventof a refrigerantrelease. Consult
manufacturer if in doubt.
The recovered refrigerantshall be returned to the refrigerantsupplier in the correct
recovery cylinder, and the relevantWaste Transfer Note arranged. Do not mixrefrigerants
in recovery unitsand especially notin cylinders.
lf compressors orcompressor oils areto be removed, ensure that theyhave been
evacuated to anacceptable level tomake certain thatflammable refrigerant doesnot
remain within the lubricant. The evacuation process shall be carried out prior to returning
the compressor tothe suppliers. Onlyelectric heating tothe compressor bodyshall be
employed to acceleratethis process. Whenoil is drainedfrom a system,it shall becarried
out safely.
