Installation

1. Siting

2. Ducting See Figs. 2, 3, 4, and 5.

a) Ensure heat pump on site is as ordered,i.e. model electrical supply and factoryfitted options.

b) Inspect unit for damage, in paticular inspectthe evaporator (finned side) to ensure that it isundamaged (minor indentations in the fins donot affect performance). If severely damagedendorse delivery note in presence of the driverand send a recorded delivery letter to thetransport company giving details.

c) Protect the unit if installation is delayed.

d) Provide a firm level base capable of supportingoperational weight of unit. Spread load if on timberfloor.

e) Ensure water cannot collect under the unit. Itis recommended that units are installed onplinths 100mm above finished floor level andalso to aid condensate drainage.

f) Allow adequate clearance to service panels onunit; recommend 500mm minimum (seeinstallation drawings).

g) All Calorex heat pumps are designed to be asquiet as practicable, however, dueconsideration should be given to siting in orderto fully exploit this feature, i.e. orientate inlet/outlet parallel to occupied premises.

h) Ensure loose debris will not block air filters orgrilles.

IMPORTANT

As Variheat units are handling air at Pool Halltemperatures, they must be sited in a warmenvironment, i.e. pool hall, or insulated plenum. Theymust not be sited in cold areas, i.e subject toambient air.

The quantity of air flow handled by each Variheatunit is given on the data sheet together withthe maximum pressure available fromthe fan to overcome total ducting resistance to airflow, i.e. inlet, discharge ducting, grilles, and whereinstalled, air heater batteries.

It is recommended that a reputable duct workcompany is associated with the duct design/manufacture and selection of grilles for the totalsystem.

Note:

1. The humidity sensing tube situated by the air inletis to be encompassed by or extended to any inlet airducting. Refer to installation drawings.

2. All units have discharge ducting spigots asstandard.

3. Inlet ducting spigots are available from stockists.

4. Final connections to Variheat spigots must bemade of flexible ducting (rubber or canvas) toeliminate transmission of vibration down the duct.

5. Before any discharge ducting is attached removeplate (if fitted) from machine outlet or fan grille.

6. After completion of installation including all grilles,ductwork etc., ensure that the air flow through themachine is as specified in the data sheet ±10%. Ifair flow is high, damp outlet to obtain correct airflow.If airflow is low or high the unit will not functioncorrectly.

But discharge from each unit must be kept separate andmust not be incorporated into one common duct system,unless non return dampers are used for each machine.

In order that moisture can be removed andhumidity control can be effected within the poolhall, it is essential that correct air movement anddistribution is achieved.

The Variheat unit must extract the humid airgenerated at pool surface and discharge the drierair to areas which are subject tio condensationproblems (windows etc and, or comfort zones,spectators, sitting out areas.

This can generally only be achieved by use ofducting and correct application of grilles/ louvresto effect air distribution and movement to theseareas.

NOTE: Variheat unit and ducting will be at poolhall temperature and will require insulation ifexposed to lower air temperatures.

Exhaust from Pool Hall - Humid Air

Should be taken as low as practicable to inlet ofVariheat unit. In many instances siting of Variheatunit in hall or changing rooms can eliminate useof duct work to inlet. If duct work is to be fitted, aninlet duct should be ordered from Calorexdistributer.

Inlet to Pool Hall- Dry Air

Generally achieved by overhead ducting withsuitable grilles to give balance and direction of airflow. Consideration must be given to duct positionin relation to pool surface, material and finishesso as not to promote maintenance problems.

Table 1

Required free areas to provide airflow to and fromheat pumps when installed in and enclosed area orwhere required to pass air through a wall etc.

Free area is the available area through which air canpass through a grille or louvres.

Note: If multiple units are installed in an enclosedarea then the inlet free areas required for each unitcan be added together to form one inlet aperture.

3. Plumbing

a) The Calorex Variheat Heat Pump must beconnected after the filter in the return pipe to thepool. If an existing heater is being retained, thenthe Calorex unit should be connected betweenthe filter and the other heater, see figure 6.

b) Calorex heat pumps have water inlet/ouletconnections as follows:

Models 550,800,1200 1½” BSP parallel, female.

Models 1400, 1800 & 4000 1½” BSP parallel,male.

c) Suitable breakable couplings should beinstalled local to heat pump.

d) If heat pump installed at lower level than poolwater then isolation valves should be fitted.

e) Drain valve or plug should be fitted to lower tofacilitate completedrain down in winter period.

f) Connections on all models from 550 to 1200 areby parallel male fittings sealed by 'O' ring orsilicone mastic these should be hand tightenedonly, otherwise damage may result to thethreads.

Note: Do not route pipes across service panels orAir In/Outlet

g) The heat exchanger in the Heat Pump will, onsmall pools, take the full flow rate of therecirculating system (see Figure 6). On largerpools a by-pass or separate auxiliary pumpmay be necessary. (bypass 1½ hp or largerwater pumps) see Figures 7 and 8.

h) The condensate drain at the base of the unitcollects the condensation from the evaporatorfins. It is therefore necessary to ensurethat the Calorex is placed on a level plinth sothat the condensate water can run away and notoverflow the edges of the drip-tray inside themachine.

Models 550,800,1200

drain connection to waste via 22mm push fitdomestic waste system.

Models 1400, 1800 and 4000

drain connection to waste via ¾2 & 1½” BSPMstubs respectively.

N.B Hose must be a watertight fit.

i) When the pipework installation is complete thepool pump should be switched on and thesystem tested for leaks. Also check the filtergauge to see that there is not an excessiveincrease in back pressure. If everything is thenworking normally the water circulating system isready to use.

j) Water circuit to and from unit to be capable ofmaintaining within specified limits the rate of flowrequired by heat pump (see data sheet).

k) All pipework must be adequately supported withallowance for expansion/ contraction especially with

plastic pipework.

I) It is recommended that when installing water systemthe last connections to be made in the system

should be the breakable connections to avoid anystresses on to the unit connections.

m)To ensure efficient operation of the Heat Pump, anadequate constant flow of water is required throughthe condenser.

This is normally achieved by ensuring that the filterpump is always operating at the same time as theHeat Pump but this requires consumption of electricitywhich would not normally be used during the filter ‘offcycle’ period.

To reduce energy consumption the installation of a twospeed or small auxillary water pump (by-passing thefilter) should be considered. This method should onlybe used on heavily used pools (4 hours turnover orless to reduce the risk of overheating due to mainpump heat input.

The circuit can be incorporated in the initial installationor added to an existing standard circuit.

IMPORTANT1) The Calorex unit must never be connected in such a

way that the Heat Pump can be switched on withoutadequate water flow through the condenser.Integral interlock terminals provided on all models(see figure 9).

2) All Pool Purifying Devices and Chemical InjectionSystems to be fitted down stream of heat pump with anon return valve to prevent concentrated chemicalsback feeding into the heat exchanger. The practice ofdosing chemicals direct into Skimmer Basket, whichresults in concentrated corrosive liquids passing overvulnerable metal components must not be allowed.

3) Water quality must be maintained not only related tosolids, etc, but also pH between 7,4 ±0,4 and, if poolwater is saline at maximum concentration of 6% wt/wt.

4) Maximum pressure of water in heat pump circuit id3kg/cm².

(140psi) 1400, 1800,4000 models.

To be in accordance with I.E.E. standards latest issueor local codes of practice, also EMC 2006/108/EC.

Protected supply to incorporate fuses or motor ratedcircuit breakers to specified rating, (see Data Sheet).H.R.C. fuses are recommended. An isolator must befitted within 2m and in sight of the machine.†

All units must be correctly earthed/grounded. An earthleakage trip of the current operating type isrecommended to be fitted to all pool electrics.

Inconsistent Electrical Supply

The following limits of operation must noy beexceeded if Calorex machines are to be guaranteedeither in performance or warranty terms.

N.B This voltage must be available at the heat pumpwhilst running.

† Note the Isolator must have a minimum of 3mm airgap when turned off.

Voltage Minimum Maximum

Single Phase Machines (U.K) 207V 253VThree Phase machines (U.K) 360V 440VSingle Phase Machines (60Hz) 187 253Three Phase machines (60Hz) 187 253Cycle Frequency 50Hz 47.5Hz 52.5HzCycle Frequency 60Hz 57.0Hz 63.0Hz

INTERLOCK

All units have interlock circuits incorporated in controlcircuit brought out to two terminals. These terminals areshorted out for factory testing.On site the shorting loop should be removed and twowires taken to pair of voltage free contacts in water pumpstarter/contactor/relay so that Heat Pump cannot operateunless water pump is operating (see page 18 fig 9).

Note

1200 and 4000 three phase machines are fitted with aphase rotation relay and will not run if the phases are notconnected in the correct order (phase sequence) or if thesupply voltage is 15% less than the nominal voltage.(415V for 3~N 50Hz) . The lamp on the phase rotationrelay, situated in the electric box, is illuminated when thephases are correctly connected and the voltage issufficient. The undervoltage protection feature is notpresent in phase protection relays fitted in 3~ 60Hzmachines.
