COMMERCIAL INSTALLATION GUIDE
2a: General Install Requirements
This water heater must be installed by a licensed tradesperson, and in accordance with:
1. AS/NZ 3500.4 National Plumbing and Draining Code, Part 4: Hot Water Supply Systems
2. AS/NZ 3500.4.2, National Plumbing and Draining Code, Part 4.2: Hot Water Supply systems – Acceptable Solutions.
3. Other relevant Australian standards, industry or local water supply regulations or codes for mains pressure
storage tanks.
*Installation within NZ must confirm to NZ Building Code G12.
Note: This water heater is not suitable for pool or building heating.
2a1: Location
a. The water heater should be located as close as possible to the most frequently used hot water outlets.
b. Adequate access must be made for service to the heat pump, water thermostat, relief valve and anode.
c. Ensure that the specification label is clearly visible. The front service cover of the heat pump section (on top
of tank) must be accessible from the front of the heater; this MUST NOT face the wall. The fan MUST NOT be
positioned up against a wall (Suggested minimum clearance 500mm *see ref Page 51-54 ).
d. The Titan Compact model has a noise level similar to an air conditioner’s outdoor unit (58dBA @ 1.5 metres);
therefore locating the unit away from office or living areas is recommended (both the owner’s & any neighbor’s).
e. Note: All models are equipped with a sacrificial anode, accessible through the top cover. We suggest
allowing 400mm above the top of the water heater (if possible) for clearance to replace the anode
(Please refer to Commercial Warranty Section Pages 36-37).
f. For single or multiple water heater installs, Quantum recommends that a 650mm x 650mm plinth be included
if installed on a floor subject to wet conditions or outdoors. In single or multiple installations a properly drained
overflow tray should be used where property damage could occur from water spillage. (See AS3500.4 for
further details.)
Note: The warranty does not cover damage due to leakage of the water heater.
2a2: Corrosion Protection
a. Fittings and the shell surface in contact with the water are to be galvanically compatible.
b. Sealants and/or Teflon plumbing tape should be used on potentially galvanically incompatible fittings. This is to
protect against possible electrolytic corrosion between the metals (where moisture penetration could occur due to
incorrectly or poorly sealed fittings).
2b: Air Flow
a. The air source models (Compact and split) extract the required heat from air being drawn through their Fin Coil
Evaporator. This produces cold exhaust air as a by-product. Therefore, good ventilation of the proposed location for
the Compact models or the split models’ separate evaporator is required.
b. The Commercial range therefore is best located externally; however a large area with a minimum of 120 cubic
meters with natural ventilation may also be acceptable. The separate evaporator in the split models could be
located externally or in a large well-ventilated ceiling space or garage. GOOD VENTILATION IS REQUIRED.
2c: Evaporator Drain
a. The evaporator drain on the Titan, Titan Split & Titan 1020 Air units should be drained to a suitable location
(as per AS/NZ 3500.4.2).
b. This can be accomplished with a length of hose or pipe but must not be connected directly to the PTR valve
or expansion valve drain.
This is because during operation, a certain amount of condensate water will flow from the evaporator drain.
If allowed to simply flow out of the outlet, this water may pool below the unit and can cause problems.
