Installation - Pentair ULTRATEMP HX-R32 Series Owner's Manual

Installation

Installation
Only a qualified service person should install the UltraTemp Heat Pump. Before installing this prod-
TM
uct, refer to the Important Warning and Safety Instructions on page 4.
Materials Needed for Installation
The following items are needed and are to be supplied by the installer for all heat pump installations:
1. Plumbing connections (50mm).
2. Level surface for proper drainage.
3. Suitable electrical supply line. See rating plate on unit for electrical specifications. A junction box is
not needed at the heat pump; connections are made inside of the heat pump electrical compartment.
Conduit may be attached directly to the heat pump jacket.
4. Electric isolation switch that will interrupt all power to the unit. This switch must be within line of
sight of the heat pump. Check local codes and wiring rules (see page 4) for requirements.
5. Watertight conduit to run the electrical supply line.
Equipment Pad
For proper drainage of condensation and rain water, place the heat pump on a flat slightly pitched
surface, such as a concrete or fabricated slab (pad). If possible, place the pad at the same level or
slightly higher than the filter system equipment pad.
Note: Be sure that the pad is pitched not more than 20mm per metre in any direction as needed for
runoff.
Drainage and Condensation
Condensation occurs from the evaporator coil while the unit is running, and drains at a steady rate (up
to 20L per hour), depending upon ambient air temperature and humidity. The more humid the ambient
conditions, the more condensation will be produced. The bottom of the unit acts as a tray to catch
rainwater and condensation. Keep the drain holes, located on the bottom pan of the base of the unit,
clear of debris.
Roof Run-off
Make sure the heat pump is not located where large amounts of water may run-off from a roof into the
unit. Sharp sloping roofs without gutters will allow massive amounts of rain water, mixed with debris
from the roof to be forced through the unit. A gutter or down spout may be needed to protect the heat
pump.
Lawn Sprinklers
Avoid placing lawn sprinkler near the heater - they can spray water into the heater and void the
warranty. Be sure to direct any spraying water away from the heater. Note the wind direction to be
sure water from sprinklers is not blown toward the heater. Sprinkler heads can produce high water
pressure and spray at an angle, different from typical rain and humid weather. Also, sprinklers con-
nected to a well water system can cause mineral build up on the evaporator coils and electronics. Salt
water can also be an issue if located near the coast.
