Installation : SGE Heat Pump should be space unit no less more 800mm. for service and cold air the space should be 2,000 mm.

Checking the mistake and method solve SGE Heat Pump system.

  1. Water Pump Overload

The mistake : cause is  adjust value rate overload not devious with rate of water overload pump. or

Overload mistake.

Modify         : Checking currant and adjust rate .

: Change new overload.

2.Compressor alarm high pressure

The mistake  : Water pump not run

: Over liquid 134a

: Water flow rate less more usual or pressure less more 2 bar

: Control valve have problem ( min PID )

: The mistake of sensor

Modify           : Solve water pump

: Reduce liquid R 134a

: Adjust control valve up

: Checking prob sensor may be mistake so make show high pressure , checking temperature water out from heat pump

is real temperature hot water out.

: Change a new pressure sensor

3.Compressor alarm low pressor

The mistake  : Liquid R 134a leak

: Evaporator block up or filter dirty.

: Blower have mistake not run

:Expansion valve or dryer block up make cannot flow liquid R134a

: Mistake of sensor

Modify          : Checking leak and solve when finished vacuum system and fill liquid R134a

: Clean Evaporator and filter.

: Checking fan blower motor .

: Change Expansion valve or dryer

: Change pressure sensor

4.Compressor overload

The mistake  : Alarm the current of compressor is high over rate standard from the rate of compressor overload adjust incorrect.

Modify          ; Checking current rate of compressor and adjust.

5.Refrigerant insufficient

The mistake  : Alarm the temperature hot water out is low more than setting rate and  not over 10 C  it over more 30 minute.

which may be liquid R134a is low more standard rate. sample is setting hot water outlet 55 C but hot water outlet flow

low more 45 C

Modify         : Checking liquid R134a in system and fill from is loss.

: Reduce % rate of control valve

: Adjust% control valve ( min PID ) over solve by adjust min PID etc from 3.5 reduce be 3

6.Probe of tank / Outlet / Disc. / Suction / Inlet Air / Inlet Water alarm from sensor measure temperature tank / hot water outlet / Liquid part of

compress / liquid part of suction / air flow to filter / water inlet .

The mistake   : Sensor measure temperature mistake or loose cable or line sensor lack of access.

Modify          : Checking line sensor may be loose cable or lack of access

: Change new sensor.

7.Power Protection : Alarm phase or Voltage

The mistake     : Electricity alternating phase or power is not fully phase.

Modify            : Checking voltage is 380 – 420 or not

: Switching 1 pair.

8.Blower overload from the current of motor is high over setting rate

The mistake      : May be adjust overload blower rate not standard.

: Overload mistake.

Modify              : Check current of motor blower and adjust for the suitable.

: Change overload

9.High heating water from alarm hot water outlet temperature is high over high temperature start

The mistake    : Water inlet to SGE Heat Pump have high over temperature sample : water from return pump flow is over hot

which hot water inlet should not over 60 C.

: Sensor mistake

: Adjust rate of control valve not suitable.

Modify           : Check water inlet must not over 60 C

: Check outlet temperature is real may be sensor mistake or loose cable which will show rate temperature not real rate.

: Check setting % max and min control valve.
