Heat Pump Manual

Terms and Conditions

Listed below are some basic operational and installation conditions that must be adhered to for
Thermex Solutions warranty to remain valid and more importantly for trouble free heat pump
operation

· If the heat pump is supplied without a pump then the minimum flow rate specified in the manual
must be maintained through the units at all times.

· The heat pump must be commissioned in accordance with the instruction in the manual and
the heat pump must be commissioned under normal operating conditions

· The operational settings on the controller must not be altered without first consulting Thermex

· The temperature cut out set point must never be set above 61°C without first consulting

Thermex Solutions

· The heat pump must be installed on level surface

· The heat pump must be powered up for at least 4 hours before starting the heat pump to allow

for the sump heater to warm the compressor oil.

· The pressure in the sealed refrigeration system must be checked by a refrigeration mechanic
before starting the heat pump to ensure that the pressure on the suction side is at least 200
kPa

· For any service work not carried out by Thermex Solutions, Thermex Solutions will only cover
costs of refrigerant to the value of the specified charge in the units.

· It is not Thermex Solutions’s responsibility to connect the heat pump to the BMS unless agreed
to before delivery of the heat pump

· The heat pump must not be installed too close to walls and other heat pumps with clearances
to be at least what is specified in the manual

that is compliant with safe work practices. Additional charges may apply for site where access
to the heat pump is unsafe or restricted

· Thermex Solutions will manufacture the heat pump to the specification provided to the sales
department. If the information supplied is incorrect Thermex Solutions takes no responsibility
for wear on the heat pump for short cycling in the case where the heat pump is over sized for
the heat load or the heat pump unable to maintain temperature when the heat pump is too
small for the heat load

· Thermex Solutions takes no responsibility for repairs carried out on the heat pump by un-
authorised service agents or if parts are installed that are not from Thermex Solutions’s
approved supplier list

· Costs for installations where a crane lift is required to undertake major repairs will not be

Heat Pump Manual

SAFETY
THE UNIT IS DESIGNED FOR OUTDOOR USE.

- This unit is designed to be safe in the use for which it was planned provided that it is
installed, started up and maintained in accordance with the instructions contained in
this manual.

- The unit contains electrical components that operate at line voltage and contains
moving parts. It therefore must be isolated from the electrical supply before being
worked on. All maintenance operations that require access to the unit must be carried
out by suitably qualified technicians who have a thorough understanding of all
necessary precautions associated with refrigeration and electrical machinery.

- The liquids to be heated must be compatible with the materials used in the
constructions of this unit. These liquids can be water or mixtures of glycol and water
for example. The liquids to be heated must not be flammable.

- All panels must be re-installed after carrying out any maintenance work.

- The unit is not to be used by the infirmed or children unless they are supervised by
responsible persons qualified to carry out the supervision.

- The unit should be secured to prevent it from toppling over.

WARNING

The unit is only to be installed, operated, maintained and serviced by
qualified persons only. Operation of units such as these can be hazardous
and should be serviced by persons with the proper training and
qualifications.

The unit and the Product Manual have markings, warning and instructions
on the safe operation of the unit and they must be adhered to.

WARNING

All wiring must be performed by qualified electricians. Improperly installed
wiring and grounding may result in electrocution and fire hazards

To avoid these hazards all wiring must be installed in accordance with all
the local relevant safety standards for wiring

WARNING

The heat pump contains refrigerants under high pressure. The system also
contains oils under high pressure. Before the refrigeration circuit can be
opened, the refrigerant should be reclaimed to reduce pressure in the
system.

Failure to recover the refrigerant to relieve pressure or the use of
refrigerants or refrigerant substitutes that are not specified for the unit may
result in system rupture and explosion.

- Where the above symbol is shown there are live electrical parts and the utmost care
should be taken. .

- Always isolate power from the unit when working on it.

- Maximum temperature setting is 60 degrees on the unit. Any higher than this may
cause problems with the condenser and/ or the water system over heating which may
become dangerous

Refrigerants have a narcotic effect when inhaled in high quantities. Should a leak occur of the
refrigerants then the room should be vacated and should only be re-entered after suitable
ventilation.

SAFETY
First Aid

- Eye Contact. Immediately flush with tepid water or sterile saline solution. Hold eyelids
apart for 15 minutes while irrigating. Seek medical attention.

- Inhalation. Remove from area of exposure immediately and if you are assisting a
victim avoid being exposed. Breathing apparatus must be worn in the presence of
high concentration of refrigerants. If victim is not breathing then apply artificial
respiration and seek urgent medical help. Give oxygen is available.

- Skin Contact. Cold Burns. Remove contaminated clothing and gently flush affected
area with warm water (30C) for 15 minutes. Apply sterile dressing and treat as for a
thermal burn. For large burns immerse in water for 15 minutes. DO NOT apply any
form if direct heat. Seek medical attention.

- Ingestion. For advice contact the poisons centre on 131126 in Australia. If swallowed
do not induce vomiting. Ingestion is considered unlikely due to product form.

- Advice to Doctor. Use of adrenaline and other catacholamines may be contraindicted
due to possible cardiac sensation. Treatment for asphyxia.

R134a HazChem code 2RE
R134a is non – flammable.
Disposal
The unit must be disposed of in a proper fashion. The refrigerants in the system must be

reclaimed by a qualified refrigeration mechanic and disposed of in accordance with the
statutory requirements. The compressor contains oil that must not be dumped.

Manual Handling
The unit weights approximately 650 kg. Do not try to move the unit manually. The unit can be

lifted with a crane (the centre of gravity is towards the front of the unit), a forklift or a pallet
jack.

GENERAL INFORMATION
The heat pump is designed to heat water to feed a central storage system. It has either an air

cooled copper and aluminium fin or a coaxial copper water sourced evaporator, a plate heat
condenser and a scroll compressor to circulate the refrigerant gas. Water is circulated out of
the unit via a pump which is not supplied with the unit. The unit has a microprocessor
controller to maintain temperature, control additional heat pumps and monitor flow through the
unit for safety reasons.

INTENDED USE
The heat pump is design to be installed outdoors and heat water to be storage in a remote

central storage location. The wetted parts in the heat pump are food grade however Thermex
takes no responsibility for the quality of the water being heated. Any other use of this water
heat pump is a not as it is intended.

Heat Pump Manual

HOT WATER CIRCUIT
The hot water circuit consists of

1. Condenser heat exchanger – this may be a plate heat exchanger, a coaxial heat
exchanger or shell and tube

2. Flow switch or flow meter

3. Copper pipe work

The heat pump will run whenever called unless the controller detects a drop in flow.
It is important to ensure that any water treatment is passive to the wetted parts of the system

which include

· Stainless Steel

· Copper

· High Density Polyethylene

· Brass

· ABS Plastic

· Nitrile Rubber

The water to water models have a water sourced evaporator that is connected to – typically –
the return condenser water from the installed chillers. This evaporator can have either a plate
heat exchanger or a coaxial heat exchanger. These heat exchangers have water flowing
through them that must be passive to the materials used. These include

· Stainless steel – 316

· Copper

· Brass
