Split Inverter Air-to-Water Heat Pump

Glycol / Water Mixture 

  If unit is operating in a cooling capacity then the 

water system must contain a mixture of inhibited 

glycol  and  water  with  thermal  protection  sufficient 

for the coldest expected temperature for the 

installation. The inhibitor level can degrade over 

time, and may need to be adjusted periodically. 

The inhibitor is essential to prevent the glycol from 

accelerating corrosion of metal components in the 

system. The glycol and inhibitor levels must be 

checked regularly (no less than once annually).

  The minimum allowable concentration of glycol is 

10% by volume in all installations.

  Automotive glycol is not suitable for use in the SIS 

system. Over time it may leave deposits which will 

degrade the performance and damage pumps or 

other devices in the system. Use only propylene 

glycol  mixtures  specifically  labeled  for  boiler  or 

HVAC use.

Obtain all components specified in the Typical System Diagram. 
Make  sure  all  components and piping comply with applicable 

local codes.

DO NOT

 use galvanized pipe anywhere in the system. 

Galvanizing will react with the glycol and can cause glycol 

degradation and sludge in the system.
•  Confirm  charge  of  expansion  tank  is  12-15  PSIG  (with  no 

water or pressure in the system).

•  Install  the  system  piping.  DO  NOT  connect  the  SpacePak 

unit to the system piping until the system has been cleaned 

as required below.

The SIS must NOT be connected to the system during this 

process.

1.  

Connect a hose from a fresh water supply to the system fill 

hose bib. Note the drain port can be used for this purpose. 

The hose bib purge/drain valve should be located low in the 

system and close to the SIS return connection.

2.  

Open the high point purge valve, (not shown in illustration, as 

it may be inside the air handler) while slowly filling the system. 

Close the valve when air is removed from the system and water 

begins to flow out of the valve.

3.  

Fill the system with fresh water and run water until the system 

has been thoroughly flushed clean. 

Automatic Fill – When an automatic fill system is installed, the 

cooling fluid (Glycol/water) must be inspected at least every 3 

months,  or  whenever  a  leak  is  detected  to  ensure  the  proper 

glycol concentration is maintained.

Pressure Test The System

1.   Add water to the system as needed to raise the pressure to 

25 PSIG (verify that all system components are suitable for 

this pressure). Verify that the pressure remains constant for 

at least one hour. Locate and correct any leaks.

2.   After successfully testing, drain the system and remove the 

fresh water hose.

3.   After testing and draining the system, apply pipe insulation. 

Fill system with glycol/water mixture. Calculate the system 

volume. 

4.   See Table 1, for required glycol concentration for the minimum 

expected outside temperature.

5.  Obtain the required volume inhibited glycol/water solution 

premixed or mix in a clean container. (The glycol must contain 

an inhibitor to prevent metal corrosion.)

6.   Pump the glycol/water solution into the system, allowing air 

to escape through the purge valve(s).

7.   After  filling  the  system,  sample  the  system  fluid  and  verify 

glycol and inhibitor percentages, following instructions 

provided with the glycol.
